About Payment Calculators

A payment calculator helps you understand the relationship between loan amount, interest rate, loan term, and monthly payment. It is useful for any fixed-rate loan — personal loans, car loans, student loans, or mortgages.

Fixed Term mode answers: "Given this loan amount and term, what will my monthly payment be?" This is the most common use case when comparing loan offers.

Fixed Payments mode answers: "If I can only afford $X per month, how long will it take to pay off this loan?" This helps you plan your budget and understand the true cost of borrowing.

Payment Tips

  • Even small extra payments each month can significantly reduce total interest paid.
  • A shorter loan term means higher monthly payments but much less total interest.
  • Reducing your interest rate by 1% can save thousands over the life of a loan.
  • Making bi-weekly payments instead of monthly can shorten your loan term by years.

Frequently Asked Questions

Monthly payment = P × [r(1+r)^n] / [(1+r)^n - 1], where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of payments. This formula ensures the loan is fully paid off at the end of the term.
