Accrued Interest
Also known as: earned interest, interest accrual
Accrued interest is the amount of interest that has built up on a loan since the last payment was made but has not yet been paid or collected. On a personal loan, interest accrues daily based on the outstanding principal balance and the daily periodic rate.
Full definition
Interest accrues continuously on most personal loans, even though payments are made monthly. Understanding accrual helps borrowers see exactly what they owe between billing cycles and why the exact payoff amount changes from day to day. How daily accrual works: Divide your annual interest rate (APR) by 365 to get the daily periodic rate. Multiply that by your current principal balance. That dollar figure is the interest accruing every day you carry the loan. Example: a $10,000 balance at 18% APR accrues approximately $4.93 per day ($10,000 x 0.18 / 365). When you make a monthly payment, the lender first applies it to accrued interest since the last payment, then applies the remainder to principal. Early in the loan term, a larger share of each payment goes to interest (since the principal is higher); later, more goes to principal. This is standard amortization. Payoff amounts: If you request a payoff quote, the lender calculates the current principal plus all accrued but unpaid interest up to the payoff date, plus any fees. The payoff amount increases each day you wait. Always ask for a payoff quote valid through the specific date you plan to send the final payment. If you miss a payment: Interest continues to accrue on the full balance during delinquency. Some lenders also charge a late fee. If interest is never paid, it may eventually be capitalized (added to principal), causing the balance to grow. Prepayment consideration: When you make extra principal payments, you reduce the balance on which future interest accrues, which saves money on the total interest paid over the life of the loan.

- APR (Annual Percentage Rate)APR is the yearly cost of borrowing, expressed as a percentage of the loan amount. It includes interest plus most lender fees, so it's a more complete measure of cost than the interest rate alone.
- Interest rateThe interest rate is the percentage of the loan balance charged per year as interest, excluding fees. It is a component of, but smaller than, the APR.
- Fixed interest rateA fixed rate stays the same for the entire life of the loan, so the monthly payment never changes. Most U.S. personal loans are fixed-rate.
- Variable interest rateA variable rate can change over the life of the loan, usually tied to an index like the prime rate. Monthly payment can rise or fall.
- Prime rateThe prime rate is the benchmark interest rate U.S. banks publish for their most creditworthy commercial customers. Many consumer rates are quoted as prime + a margin.
- Loan termThe loan term is how long you have to repay the loan, usually expressed in months. Common personal-loan terms are 24, 36, 48, 60, and 72 months.
