APR basics

How APR works

Annualized cost

APR expresses borrowing cost as an annual percentage so loan offers are easier to compare.

Interest plus fees

APR usually includes interest and required finance charges such as origination or lender fees.

Term matters

The same fee can create a higher APR on a short loan than on a longer loan.

Compare similar loans

APR works best when comparing loans with similar terms, repayment schedules, and fee structures.

Comparison

APR vs interest rate

Interest rate

5.00%

The interest rate is the advertised yearly cost of borrowing the principal before certain fees are included.

APR

Formula

APR formula explanation

Periodic payment

Payment = P × r × (1 + r)^n / ((1 + r)^n − 1)

The scheduled payment is estimated from the loan amount, periodic rate, and number of payments.

Net amount received

Net Amount = Loan Amount − Required Fees

APR uses the amount effectively received after upfront required fees.

APR estimate

APR = Periodic Cost Rate × Payments Per Year

The calculator solves for the periodic rate that matches the payment stream, then annualizes it.

APR calculations may vary by loan type, jurisdiction, and which fees are legally included. This calculator is an educational estimate and does not provide lending, legal, or tax advice.
