Notes payable are written promises to pay a specified principal, usually with interest, under stated terms. A note may arise from a bank loan, equipment purchase, property financing, or conversion of an overdue supplier balance.
Notes payable are liabilities. The portion due within one year or the operating cycle is generally current, while later principal is presented as noncurrent under the applicable accounting rules.
Notes payable vs. accounts payable
| Feature | Notes payable | Accounts payable |
|---|---|---|
| Documentation | Formal note or loan agreement | Supplier invoice and purchase terms |
| Interest | Usually explicit | Usually not explicit within normal terms |
| Duration | Short- or long-term | Normally short-term trade credit |
| Security | May be secured or unsecured | Generally unsecured trade obligation |
| Covenants | May include financial and operational requirements | Typically purchase and payment terms |
Simple interest formula
Interest = principal × annual interest rate × time
A $12,000 note at 10% for two months produces:
$12,000 × 10% × 2/12 = $200 interest
Journal entry when cash is borrowed
| Account | Debit | Credit |
|---|---|---|
| Cash | $12,000 | — |
| Notes payable | — | $12,000 |
Cash increases and the liability increases. The entry can be visualized with the debit and credit rules in our T-account guide.
Accrue interest at period end
If $100 of interest has accrued but is unpaid at month-end:
| Account | Debit | Credit |
|---|---|---|
| Interest expense | $100 | — |
| Interest payable | — | $100 |
This recognizes the cost in the period incurred rather than waiting for cash payment.
Entry when the note is paid
At maturity, assuming total interest is $200 and $100 was already accrued:
| Account | Debit | Credit |
|---|---|---|
| Notes payable | $12,000 | — |
| Interest payable | $100 | — |
| Interest expense | $100 | — |
| Cash | — | $12,200 |
Amortizing notes
With an amortizing loan, each payment contains interest and principal. Interest is calculated on the outstanding balance under the agreement, so the interest portion normally falls as principal is repaid.
| Payment component | Calculation |
|---|---|
| Interest | Opening principal × periodic rate |
| Principal | Total payment − interest |
| Ending balance | Opening principal − principal paid |
An amortization schedule supports payment, classification, interest accrual, and reconciliation. Variable rates, balloon payments, fees, discounts, and modification terms require additional analysis.
Balance-sheet presentation
Separate the current principal due from the long-term portion. Interest payable is generally shown separately. Disclose material terms, collateral, maturities, rates, covenant violations, guarantees, and refinancing facts when required.
Adding a current portion can reduce the current ratio. A business should forecast principal and interest dates rather than evaluating debt only at year-end.
Control checklist
- Maintain the signed note, amendments, collateral, and lender correspondence.
- Reconcile lender statements to the general ledger.
- Separate principal, interest, fees, and escrow.
- Track payment dates, rate resets, balloon amounts, and covenants.
- Obtain approval for new borrowing and modifications.
- Confirm current/noncurrent classification at every reporting date.
- Model covenant and liquidity effects before a distribution or new debt.
Frequently asked questions
Is notes payable an expense?
No. Principal is a liability. Interest and certain fees may become expense or be accounted for under other applicable rules.
Is notes payable a debit or credit balance?
It normally has a credit balance. Borrowing credits the liability; principal repayment debits it.
Can accounts payable become notes payable?
Yes. A supplier and customer may formally convert an overdue trade balance into an interest-bearing note, which requires appropriate entries and documentation.
