Formula and assumptions

How the calculator works

Monthly Rate = Annual Rate / 12 Monthly Payment = Principal × r × (1 + r)^n / ((1 + r)^n - 1) Total Interest = Total Paid - Principal

Common mistakes this catches

  • Only checking whether the payment fits this month.
  • Ignoring insurance, maintenance, taxes, fees, and down payment.
  • Assuming the calculator matches lender terms exactly.
