Formula used

Monthly payment = P × r(1+r)^n ÷ ((1+r)^n − 1). Each month: interest = opening balance × r; principal paid = payment + extra payment − interest; new balance = opening balance − principal paid.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Fixed-rate principal-and-interest schedule only. Compare against lender statements before making financial decisions.

  • The loan has a fixed annual rate converted to a monthly rate.
  • Payments are monthly and the first payment is one month after the starting balance.
  • Extra monthly payment is treated as principal reduction with no fee or prepayment penalty.
  • Taxes, insurance, redraw fees, offset accounts, variable-rate changes and lender servicing fees are excluded.

Master’s Tip

How to use the result well

Master’s Tip: print the selected payment row beside the lender statement. Small rate changes, fee timing, skipped payments or a different compounding convention can explain why a lender balance is not exactly the same as a simple public calculator.

Visual proof

Principal progress

Principal paid after payment 60Interest share of paid cash

Principal progress is slowest near the start because interest is calculated from the remaining balance each month.

Method

Monthly payment = P × r(1+r)^n ÷ ((1+r)^n − 1). Each month: interest = opening balance × r; principal paid = payment + extra payment − interest; new balance = opening balance − principal paid.

  1. For 250,000 at 6.5% over 30 years, r = 0.065 ÷ 12 and n = 360. The scheduled monthly payment is about 1,580.17. Month 1 interest is about 1,354.17, so only about 226.00 reduces principal before any extra payment.

Assumptions

  • The loan has a fixed annual rate converted to a monthly rate.
  • Payments are monthly and the first payment is one month after the starting balance.
  • Extra monthly payment is treated as principal reduction with no fee or prepayment penalty.
  • Taxes, insurance, redraw fees, offset accounts, variable-rate changes and lender servicing fees are excluded.
