accrued interest
UCC / CommercialLegal glossary term
Quick answer
Accrued interest usually means interest that has accumulated but not yet been paid. In contracts, it matters because it can swell the debt owed. Before signing, check the rate, compounding method, and when it starts.
Definitions
What is accrued interest?
Legal Definition
Accrued interest is the interest that builds up on a loan or obligation but has not yet been paid. It creates a right for the creditor to receive that amount when payment is due, and it may increase the total outstanding balance. The calculation method—simple versus compound—often determines the final sum.
Plain-English Translation
Think of a library fine that keeps adding each day you keep the book; the fine grows even though you haven’t paid it yet.

accrued interest vs similar terms
| Related term | Plain meaning | Main difference from accrued interest |
|---|---|---|

| Compound interest | Interest on interest | Accrued interest may be simple or compound, affecting total owed |
Missing or vague
If accrued interest is missing or vague
If a contract omits a clear definition of accrued interest, parties may dispute when interest starts to pile up. The borrower might argue that interest should not begin until a formal default notice, while the lender could claim immediate accrual. Such ambiguity often leads to litigation over the amount owed and can delay repayment.
Without a specified rate or compounding method, courts may apply statutory defaults, which may not reflect the parties' intent. The resulting uncertainty can increase transaction costs and damage business relationships.

Document context
How accrued interest shows up in legal documents

Who is affected?
The lender gains a claim for additional compensation, while the borrower risks an inflated repayment amount.
How does it work?
