Estimates for a fixed-rate loan with equal monthly payments. Lenders that use daily simple interest charge interest on the exact days between payments, so paying early or late changes the interest slightly.
How to read the schedule
- Payment: the same each month, except possibly the last, which is whatever clears the balance.
- Interest: last month’s balance × APR ÷ 12. It falls every month.
- Principal: payment minus interest. It rises every month.
- Balance: what you still owe. On a simple interest loan, this is also roughly your payoff amount, plus interest accrued since the last payment.
