Loan Calculator Formula & How It Works

M = P × [r(1+r)ⁿ] / [(1+r)ⁿ − 1]
  • M = Monthly payment
  • P = Principal (loan amount)
  • r = Monthly interest rate = Annual Rate ÷ 12 ÷ 100
  • n = Total number of monthly payments

This standard loan amortization formula computes a fixed monthly payment that covers both interest on the remaining balance and principal repayment. Total interest paid = (M × n) − P. The same formula applies to mortgages, car loans, student loans, and personal loans.

Loan Calculator FAQs

How do you calculate a monthly loan payment?

Monthly payment = P × [r(1+r)ⁿ] / [(1+r)ⁿ − 1]. For a $10,000 loan at 8% for 3 years: r = 0.08/12 = 0.006667, n = 36, M = $313.36.

What factors affect loan monthly payment?

Three main factors: loan amount (higher = bigger payment), interest rate (higher = bigger payment), and loan term (longer term = smaller monthly payment but more total interest).

Should I get a longer or shorter loan term?

Shorter term: higher monthly payments but less total interest. Longer term: lower monthly payments but significantly more total interest paid. Choose based on your cash flow needs and total cost.
