How it works
Formula & explanation
APR Calculator uses the following calculation:
Solve r in: Payment = (Amount−Fees) × r(1+r)n / [(1+r)n−1]
This is a simplified model intended for planning and education. Real-world offers from lenders, institutions, or tax authorities may include additional fees, rules, or adjustments not reflected here.
FAQ
Frequently asked questions
Why is APR different from the interest rate?
APR spreads upfront fees over the life of the loan, giving a fuller picture of borrowing cost than the interest rate alone.
Is a lower APR always the better loan?
Usually, but compare APRs only between loans with similar terms — a shorter loan naturally shows a different APR impact from fees.
Do all fees count toward APR?
Federal disclosure rules define which fees are included; some third-party costs like appraisal fees typically aren't.
