What does a loan calculator tell you?

The loan calculator shows your exact monthly payment, total interest paid, and total loan cost. With this information you can compare different amounts, terms, and interest rates to choose the best loan and accurately plan your monthly budget.

Loan payment formula

Payment = P × [r(1+r)^n] ÷ [(1+r)^n − 1]

  • P = Loan principal
  • r = Monthly interest rate (annual rate ÷ 12)
  • n = Number of monthly payments

Practical example

$10,000 loan at 6% annual rate over 3 years (36 months).

  1. Monthly rate: 6% ÷ 12 = 0.5% = 0.005
  2. Monthly payment: ≈ $304/month
  3. Total paid: $304 × 36 = $10,944
  4. Total interest: $10,944 − $10,000 = $944

Tips to reduce loan cost

  • Compare APR (not just nominal rate) for the true cost including fees.
  • Shorten the term if you can: less time = less total interest.
  • Make extra payments to reduce principal and cut future interest.
  • Check for prepayment penalties before paying ahead of schedule.
