Loan Payment Calculator

What Affects Your Loan Payment

  • Principal — The total amount you're borrowing.
  • Interest rate (APR) — The annual cost of borrowing, including fees in most cases.
  • Term length — How many months or years you have to repay the loan.
  • Payment frequency — Most loans are paid monthly, which this calculator assumes.

Personal Loans vs. Auto Loans vs. Student Loans

Personal loans are typically unsecured and carry higher rates than auto loans, which are backed by the vehicle itself. Student loans often have longer terms and, for federal loans, fixed rates set by the government. Run each scenario through the calculator to see how term length and rate change your total cost.

Tips for a Cheaper Loan

  1. Compare rates from multiple lenders before committing.
  2. Choose the shortest term you can afford to minimize total interest.
  3. Check for origination fees that can add to your effective rate.
  4. Improve your credit score beforehand to unlock better offers.
