What is a Promissory Note With Acceleration Clause?

A Promissory Note With Acceleration Clause is a legally binding written instrument in which a borrower (the maker) unconditionally promises to repay a specified principal amount β€” plus interest β€” to a lender (the payee) according to a defined repayment schedule, with an added provision that makes the entire outstanding balance immediately due and payable if the borrower defaults. The acceleration clause transforms what would otherwise be a series of separate installment claims into a single, immediately enforceable debt obligation the moment a defined trigger event occurs β€” such as a missed payment, insolvency, or bankruptcy filing. It is the standard form for private commercial lending, seller-financed transactions, shareholder loans, and any structured loan arrangement where the lender needs a clear, swift collection remedy.

Why You Need This Document

A loan advanced without a signed promissory note is effectively an unsecured gift in any courtroom β€” you have no written evidence of the terms, the interest rate, or the repayment schedule, and collecting on it requires proving an oral agreement, which courts treat with considerable skepticism. Without an acceleration clause specifically, a lender whose borrower stops paying can only sue for each missed installment as it comes due, dragging out collection over months or years while the borrower's assets erode. The acceleration clause closes this gap: one default, one demand, one lawsuit for the full balance. It also signals to the borrower at the outset that the lender is serious β€” reducing the frequency of missed payments in practice. This template gives private lenders, business owners, and seller-financiers a professionally drafted, jurisdiction-aware starting point they can complete in under 30 minutes, without paying a lawyer to draft from scratch for a routine transaction.

Common mistakes to avoid

❌ Setting an interest rate above the jurisdiction's usury ceiling

Why it matters: A usurious rate can render the interest provisions void or, in some states, void the entire note β€” leaving the lender unable to collect any interest and potentially forfeiting principal.

Fix: Look up the applicable usury limit for the borrower's state or province before executing. For commercial loans between businesses, usury ceilings are often higher or inapplicable, but confirm this in writing from a licensed attorney.

❌ Omitting a defined list of default events beyond missed payment

Why it matters: A borrower can remain technically current on installments while filing for bankruptcy, encumbering collateral, or entering a transaction that makes collection impossible β€” leaving the lender with no acceleration right.

Fix: Include at least five default triggers: payment default, insolvency, bankruptcy filing, judgment liens exceeding a defined threshold, and breach of any agreement securing the note.

❌ No anti-waiver clause

Why it matters: Accepting a late payment without reserving rights can be construed as a course-of-dealing waiver, making it harder to accelerate on a later default after a pattern of tolerance.

Fix: Add a standard anti-waiver provision stating that acceptance of any payment β€” late or partial β€” does not waive the lender's right to enforce the note strictly on any subsequent default.

❌ Making acceleration automatic rather than optional

Why it matters: Automatic acceleration triggers the entire balance due without lender action, which can complicate workout negotiations, modify subordination arrangements, and expose the lender to claims they acted in bad faith.

Fix: Draft the clause as 'at the option of Payee, the entire balance shall become immediately due' β€” this preserves lender flexibility to forbear, negotiate, or accelerate on their own timeline.

❌ Executing the note after funds have already been advanced

Why it matters: A note signed after the loan is made may lack consideration in some jurisdictions, making it potentially unenforceable as a matter of contract law.

Fix: Always execute the promissory note before or simultaneously with the transfer of funds. If funds were advanced informally, have a lawyer draft a ratification agreement alongside the note.

❌ Failing to attach or reference an amortization schedule

Why it matters: Disputes over how much principal remains outstanding β€” especially after partial prepayments or negotiated deferrals β€” are common and expensive to resolve without a contemporaneous schedule.

Fix: Attach a full amortization table as Exhibit A at signing and update it in writing any time the repayment terms are modified.

The 10 key clauses, explained

Parties, Principal Amount, and Loan Date

In plain language: Identifies the lender and borrower as legal entities or individuals, states the principal loan amount, and records the date the note is executed and funds are advanced.

Sample language
For value received, [BORROWER FULL LEGAL NAME] ('Maker'), promises to pay to the order of [LENDER FULL LEGAL NAME] ('Payee') the principal sum of $[AMOUNT] ([WRITTEN AMOUNT] Dollars), advanced on [DATE].

Common mistake: Using informal names or trade names instead of full legal names. If the borrower defaults and enforcement is required, the note must identify the correct legal party to sue.

Interest Rate and Calculation Method

In plain language: States the annual interest rate, whether it is fixed or variable, how it is calculated (simple or compound), and the basis for daily accrual.

Sample language
This Note shall bear interest at the rate of [X]% per annum, calculated on the basis of a 365-day year on the unpaid principal balance from the date of this Note until paid in full.

Common mistake: Omitting the calculation basis (365-day vs. 360-day year). The difference affects accrued interest on large principals and has been the subject of litigation in commercial lending disputes.

Repayment Schedule

In plain language: Sets out the payment frequency, payment amount, first payment date, and whether payments are interest-only, fully amortizing, or structured with a balloon.

Sample language
Maker shall pay [MONTHLY / QUARTERLY] installments of $[AMOUNT], beginning on [FIRST PAYMENT DATE], with a final balloon payment of all remaining principal and accrued interest due on [MATURITY DATE].

Common mistake: Leaving the repayment structure ambiguous by stating only the maturity date without specifying interim payments. Courts have had to imply repayment terms, with results unfavorable to the lender.

Acceleration Clause

In plain language: Grants the lender the right to declare the entire unpaid balance β€” principal plus accrued interest β€” immediately due and payable upon the occurrence of any defined default event.

Sample language
Upon the occurrence of any Event of Default, at the option of Payee, the entire unpaid principal balance of this Note, together with all accrued and unpaid interest, shall immediately become due and payable without further notice or demand.

Common mistake: Forgetting to specify that acceleration is at the lender's option rather than automatic. Automatic acceleration can trigger unintended consequences β€” including accelerating subordinate obligations β€” before the lender is ready to enforce.

Events of Default

In plain language: Lists the specific circumstances that constitute a default, such as missed payments, insolvency, bankruptcy filing, breach of a related agreement, or material misrepresentation.

Sample language
Each of the following shall constitute an Event of Default: (a) Maker fails to pay any installment within [X] days of its due date; (b) Maker files for bankruptcy or becomes insolvent; (c) Maker breaches any material term of any agreement securing this Note.

Common mistake: Defining default only as missed payment and omitting insolvency, judgment liens, and breach of related collateral agreements. A borrower can be technically current on payments while their financial position deteriorates to the point where collection becomes impossible.

Cure Period and Notice

In plain language: Gives the borrower a defined period β€” typically 5 to 30 days β€” to remedy a default after written notice from the lender, before acceleration or other remedies are exercised.

Sample language
Payee shall provide Maker with written notice of any Event of Default. Maker shall have [X] calendar days from receipt of such notice to cure the default before Payee may exercise acceleration or any other remedy.

Common mistake: Including no cure period at all. Courts in many jurisdictions imply a reasonable cure opportunity even when the note is silent; specifying the period gives the lender control over the timeline and reduces legal risk.

Late Payment Penalty

In plain language: Imposes a fixed fee or percentage charge on any payment not received within a defined grace period after its due date.

Sample language
If any payment is not received within [X] days of its due date, Maker shall pay a late charge equal to [X]% of the overdue payment, but not less than $[MINIMUM] and not more than $[MAXIMUM], as liquidated damages.

Common mistake: Setting late fees as a flat dollar amount rather than a percentage of the overdue payment. On a large loan, a flat $25 late fee is commercially meaningless and provides no incentive for timely payment.

Prepayment Rights

In plain language: States whether the borrower may repay the loan early, and if so, whether a prepayment penalty applies and how it is calculated.

Sample language
Maker may prepay this Note in whole or in part at any time without penalty. [ALTERNATIVE: Maker may prepay this Note, provided that any prepayment within the first [X] months shall be subject to a prepayment fee equal to [X]% of the amount prepaid.]

Common mistake: Remaining silent on prepayment. In many jurisdictions, silence means prepayment is permitted without penalty β€” lenders who intend to charge a yield-maintenance fee must expressly state it.

Governing Law and Venue

In plain language: Specifies which jurisdiction's law governs interpretation and enforcement of the note, and where any legal proceedings must be filed.

Sample language
This Note shall be governed by and construed in accordance with the laws of the State of [STATE], without regard to its conflict-of-law provisions. Any legal action shall be brought exclusively in the courts of [COUNTY], [STATE].

Common mistake: Choosing a governing law with no connection to either party. Courts may disregard a governing-law clause that appears designed to avoid the borrower's home-state consumer protections or usury limits.

Waiver of Presentment and Demand

In plain language: The borrower formally waives the right to require the lender to present the note, make formal demand, give notice of dishonor, or protest before enforcement β€” streamlining collection.

Sample language
Maker and all endorsers, sureties, and guarantors hereby waive presentment, demand for payment, notice of dishonor, protest, and notice of protest, and consent to any extension of time for payment without notice.

Common mistake: Omitting the waiver clause entirely and relying on state-law defaults. Several states require formal presentment and demand before a note holder can sue β€” the waiver clause removes this procedural barrier.

How to fill it out

  1. 1

    Identify both parties with their full legal names

    Enter the borrower's and lender's complete legal names β€” individual or registered entity β€” along with addresses. For businesses, use the exact name on the incorporation or registration certificate.

    πŸ’‘ For LLC or corporate borrowers, confirm the signing officer has authority to bind the entity; attach a board resolution or member consent if the loan is material.

  2. 2

    Set the principal amount and loan date

    Enter the exact dollar amount being lent and the date funds are or will be advanced. If funding occurs in tranches, use the date of the first advance and attach a disbursement schedule.

    πŸ’‘ Write the amount in both numerals and words β€” e.g., '$50,000 (Fifty Thousand Dollars)' β€” to prevent disputes over transcription errors.

  3. 3

    Define the interest rate and confirm it is below your jurisdiction's usury ceiling

    State the annual rate, whether fixed or variable, and the calculation basis (365-day year is most common). Check your state or provincial usury limit before setting the rate.

    πŸ’‘ For variable-rate notes, tie the rate to a published index (e.g., Wall Street Journal Prime Rate) plus a spread, and cap the maximum rate to reduce borrower default risk.

  4. 4

    Build the repayment schedule

    Specify payment frequency, the dollar amount of each installment, the first payment date, and the maturity date. Decide whether the note is fully amortizing, interest-only with a balloon, or structured differently.

    πŸ’‘ Attach a full amortization table as Exhibit A so both parties can verify each payment reduces principal as expected β€” this prevents disputes mid-term.

  5. 5

    Draft the events of default and cure period

    List every trigger that will constitute a default β€” missed payment, insolvency, bankruptcy, breach of related agreements β€” and specify the number of days the borrower has to cure after written notice.

    πŸ’‘ A 10-day cure period for payment default and a 30-day period for non-payment defaults is a commonly accepted commercial standard that balances lender protection with borrower fairness.

  6. 6

    Confirm the acceleration clause is at the lender's option

    Review the acceleration provision to ensure it says 'at the option of Payee' rather than triggering automatically. Add language specifying that failure to exercise acceleration on one default does not waive the right on a later default.

    πŸ’‘ Include an anti-waiver clause: 'No failure or delay by Payee in exercising any right shall constitute a waiver of that right.' This protects lenders who accept a late payment without intending to forgive future defaults.

  7. 7

    State prepayment and late-fee terms explicitly

    Decide whether early repayment is allowed without penalty, and set your late-fee rate as a percentage of the overdue amount with a grace period of 5 to 10 days.

    πŸ’‘ Courts scrutinize late fees as potential penalties β€” framing them as 'liquidated damages reflecting estimated collection costs' strengthens enforceability.

  8. 8

    Execute before funds are advanced

    Both parties must sign the note before or simultaneously with the transfer of funds. Date the note accurately and retain the original signed copy in a secure location.

    πŸ’‘ Have the note notarized even if not legally required β€” notarization authenticates signatures and simplifies enforcement if the borrower later denies signing.

Frequently asked questions

What is a promissory note with an acceleration clause?

A promissory note with an acceleration clause is a written, signed promise to repay a specified loan amount under defined terms β€” including a provision that makes the entire unpaid balance immediately due if the borrower defaults. The acceleration clause is the lender's most powerful collection tool: rather than suing for each missed installment separately, the lender can call the full balance due at once and pursue enforcement in a single action.

When should I use an acceleration clause in a promissory note?

Include an acceleration clause any time there is meaningful default risk β€” specifically when the loan is unsecured, when the borrower's financial position could deteriorate, or when the repayment term exceeds 12 months. Short-term loans between trusted parties with strong collateral may not require one, but for most commercial and private lending situations the acceleration clause is standard practice and is expected by sophisticated lenders and borrowers alike.

Is a promissory note legally binding without notarization?

In most US states, Canada, and the UK, a promissory note is legally binding when signed by the borrower (maker) β€” notarization is generally not required for enforceability. However, notarization authenticates the signatures and makes the document self-proving in court, which simplifies enforcement if the borrower later claims they did not sign. Some jurisdictions require notarization for notes secured by real property.

What is the difference between a secured and an unsecured promissory note?

An unsecured promissory note, like this template, is backed only by the borrower's personal or corporate promise to pay. A secured promissory note is backed by a specific asset β€” real estate, equipment, receivables β€” that the lender can seize upon default. Secured notes generally carry lower interest rates because the lender has a defined recovery path. Unsecured notes rely entirely on the acceleration clause and subsequent judgment enforcement for collection.

How does an acceleration clause interact with bankruptcy?

When a borrower files for bankruptcy, an automatic stay under US Bankruptcy Code Β§362 typically halts the lender's ability to enforce the acceleration clause or collect on the note outside the bankruptcy proceeding. The lender must file a proof of claim and may need to seek relief from the automatic stay to pursue collateral. In Canada, similar stay protections apply under the Companies' Creditors Arrangement Act and the Bankruptcy and Insolvency Act. Including bankruptcy as a defined default event is still important β€” it preserves the acceleration right for use after stay relief is obtained.

What interest rate can I charge on a promissory note?

The maximum allowable rate depends on the jurisdiction and whether the note is a consumer or commercial transaction. In the US, usury laws vary by state β€” consumer loan limits range from 10% to 36% annually depending on the state, while many states exempt business-to-business loans above a threshold principal amount. In Canada, the Criminal Code sets a maximum effective annual rate of 60% for all loans. In the UK, consumer credit regulations cap certain loan rates, while commercial rates are largely unregulated. Always confirm the applicable ceiling before drafting.

Can the borrower prepay a promissory note early?

Unless the note expressly prohibits or penalizes prepayment, the borrower generally has the right to repay early in most jurisdictions. Lenders who want to preserve expected interest income should include a prepayment penalty clause β€” typically a percentage of the outstanding principal during a defined penalty period. For longer-term commercial notes, a yield-maintenance formula may be used instead of a flat percentage.

What happens if the lender waives one default β€” does that waive future defaults?

Without an anti-waiver clause, a pattern of accepting late payments or overlooking minor defaults can create a course-of-dealing argument that the lender waived strict compliance. With a properly drafted anti-waiver clause, acceptance of any payment β€” on time, late, or partial β€” does not waive the lender's right to strictly enforce the note going forward. This is one of the most important protective provisions a lender can include.

Do I need a lawyer to draft a promissory note with an acceleration clause?

For straightforward loans between businesses in a single jurisdiction with standard repayment terms, a high-quality template is typically sufficient. Engage a lawyer when the loan exceeds $100,000, when collateral is involved, when the borrower is in a different jurisdiction, when the transaction is cross-border, or when the note is part of a broader financing arrangement with subordination or intercreditor agreements. A 1–2 hour legal review typically costs $300–$600 and is worthwhile for any loan where collection risk is significant.

How this compares to alternatives

vs Simple Promissory Note

A simple promissory note documents the loan and repayment terms but does not include an acceleration clause. If the borrower misses a payment, the lender can only sue for that installment β€” not the full balance. The acceleration clause version is appropriate any time there is meaningful default risk or the repayment term exceeds 12 months.

vs Secured Promissory Note

A secured promissory note attaches a specific asset as collateral, giving the lender a priority claim to seize that asset upon default. An unsecured note with an acceleration clause relies on the borrower's general creditworthiness and subsequent judgment enforcement. Use the secured version when the loan is large, the borrower's credit is uncertain, or a specific asset directly supports repayment.

vs Demand Promissory Note

A demand note makes the entire balance payable whenever the lender chooses to demand it β€” there is no fixed repayment schedule and no specific default trigger required. A note with an acceleration clause has a defined schedule and requires a default event before the lender can call the balance. Demand notes are simpler but give the borrower no schedule certainty; acceleration-clause notes balance lender protection with a predictable repayment structure.

vs Loan Agreement

A loan agreement is a comprehensive bilateral contract covering all lending terms in detail β€” covenants, representations, conditions precedent, and remedies β€” typically used for larger or more complex transactions. A promissory note is a simpler, one-sided instrument focused on the borrower's payment obligation. For loans above $250,000 or with multiple financial covenants, a full loan agreement provides stronger protection; a promissory note with acceleration is appropriate for straightforward private lending arrangements.

Industry-specific considerations

Real Estate

Seller-financed transactions use acceleration clauses tied to property insurance lapse, title transfer without consent (due-on-sale), or missed installments β€” protecting the seller's security interest in the property.

Small Business and Startups

Shareholder loans and bridge notes between related parties rely on acceleration clauses to protect lenders if the company enters insolvency proceedings or closes a funding round that could dilute repayment priority.

Manufacturing and Equipment

Equipment purchase financing documented by a promissory note typically ties acceleration to physical destruction, unauthorized sale, or failure to maintain insurance on the financed asset.

Professional Services

Law firms, accountancies, and consulting practices use promissory notes when partners buy into or out of the firm on installment terms, with acceleration triggered by departure, disbarment, or breach of the partnership agreement.

Jurisdictional notes

United States

Usury laws vary by state β€” consumer loan rate ceilings range from 10% (California) to 36% (payday-loan regimes), while many states exempt commercial loans above $250,000 from usury limits entirely. Acceleration clauses are broadly enforceable in commercial transactions; however, mortgage-backed notes are subject to federal and state foreclosure procedures that impose additional notice and cure requirements before acceleration can be exercised against real property.

Canada

The Criminal Code of Canada caps the effective annual interest rate at 60% for all loans, including fees and charges. Acceleration clauses are enforceable across provinces, but Quebec's Civil Code requires clear, unambiguous language and may impose additional borrower-protection requirements. Ontario's Mortgages Act governs acceleration on real-property-secured notes and requires specific notice periods. Notes between related corporations may attract scrutiny under thin-capitalization tax rules.

United Kingdom

Commercial promissory notes are governed by the Bills of Exchange Act 1882, which recognizes the acceleration clause as a standard term. Consumer credit transactions are regulated by the Consumer Credit Act 1974, imposing form requirements and a 14-day cooling-off period. The Financial Conduct Authority regulates consumer lending rates. For business-to-business notes, there are no statutory interest-rate caps, but courts may strike terms that are found to be unfair or penal in nature.

European Union

The EU Consumer Credit Directive limits interest rates and requires mandatory pre-contractual disclosure for consumer loans; business lending is largely governed by member-state law. Germany, France, and the Netherlands each impose their own usury ceilings for consumer transactions. GDPR considerations apply where the note involves personal data processing between parties. Acceleration clauses in cross-border EU commercial lending are generally enforceable under Rome I Regulation, which allows parties to choose governing law, subject to overriding mandatory provisions of the borrower's home member state.
