How the Mortgage Formula Works

The calculator uses the standard mortgage amortization formula to estimate monthly payments.

The formula calculates:

  • Loan balance repayment
  • Monthly interest costs
  • Fixed-term payment schedules

The monthly mortgage payment depends on:

  • Interest rate
  • Loan duration

Higher interest rates increase total borrowing costs, while larger down payments reduce the financed amount.
