APR Calculator

What Is APR?

APR (Annual Percentage Rate) is the all-in cost of borrowing money for one year. It’s more than just the interest rate you see advertised. APR includes:

  • Interest Charges: The cost you pay each month for borrowing.
  • Processing Fees: One-time fees the lender charges to handle your loan.
  • Origination Fees: A percentage of your loan amount, charged upfront.
  • Other Loan-Related Costs: Any extra charges the lender adds.

Why APR Matters More Than Interest Rate

  • True Comparison: Two loans might both say “5% interest,” but if one has a $300 origination fee and the other doesn’t, their APRs will differ.
  • No Surprises: APR uncovers hidden fees, so you won’t be hit with unexpected costs.
  • Standard Measure: It’s a uniform way to compare loans from banks, credit unions, and online lenders.
