Year Principal Paid Interest Paid Remaining Balance

How are mortgage payments calculated?

Fixed-rate loan amortization uses an annuity formula where each monthly payment remains identical while the split between principal reduction and accrued interest shifts progressively over time.

The true cost of loan duration and interest

Shortening loan term from 25 to 20 years substantially decreases total interest paid, even if monthly installments are marginally higher.
