What is the difference between the interest rate and the APR?

The interest rate is the cost you pay each year to borrow the principal amount, expressed as a percentage. The APR (Annual Percentage Rate) includes the interest rate plus other costs such as fees, points, and insurance, giving a more complete picture of the yearly cost of the loan.

Can I use this calculator for any type of loan?

Yes, the General APR Calculator works for personal, auto, or business loans. The Mortgage APR Calculator is designed specifically for home loans in the United States and factors in down payment, loan term, and PMI if applicable.

How often are payments made if I select biweekly or weekly compounding?

Payment frequency refers to how often you make your regular loan payment (e.g., every two weeks or every week). Compounding frequency affects how interest is calculated on the remaining balance; more frequent compounding can slightly increase the total interest paid over the loan term.

What does the 'Upfront Fees' field represent?

Upfront fees are one-time charges added to the loan at closing, such as origination fees, application fees, or points. Including these fees in the calculator raises the real APR, reflecting the true cost of borrowing.

About this tool

What APR Calculator does

The APR Calculator on Calculator.net reveals the true yearly cost of borrowing by combining interest rates with upfront fees, points, and compounding frequency. The General APR Calculator lets users input a loan amount, term, interest rate, and optional fees to compute a real APR alongside monthly payment totals and an amortization schedule. A separate Mortgage APR Calculator tailors the inputs for home loans, factoring in house value, down payment, loan term, interest rate, points, and annual PMI. Both versions output the real APR, amount financed, total interest paid, and a full payment breakdown, giving borrowers a clear picture of what they will actually pay over the life of the loan.
