Beginner guide

Start with the payment, then check the interest

The monthly payment tells you whether the loan fits your cash flow. The total interest tells you how much the loan costs beyond the amount you borrowed.

A longer term usually lowers the monthly payment, but it can make the total interest much larger. That tradeoff is the first thing to compare.

  • Use years for a quick estimate, or months when the lender quotes an exact term.
  • Compare two terms with the same rate to see how much the lower payment really costs.
  • If fees are financed, add them to the loan amount before calculating.

What the schedule is showing

The schedule breaks each month into interest and principal. Early payments usually contain more interest. Later payments reduce the balance faster.

Formula

Monthly payment = P x r x (1 + r)^n / ((1 + r)^n - 1), where P is principal, r is monthly interest rate, and n is number of monthly payments.

Example

A $25,000 loan at 7.5% for 5 years has an estimated monthly payment of about $501.

Result notes
