Worked example
Example: $300,000 for 30 years at 6.5%
- Payment = $1,896.20
- Month 1 interest = 300,000 × 0.065 ÷ 12 = $1,625.00
- Month 1 principal = 1,896.20 − 1,625.00 = $271.20
Early payments are mostly interest; by year 20 most of each payment is principal.
Formula
Interestₘ = Balanceₘ₋₁ × r
Principalₘ = Payment − Interestₘ
Balanceₘ = Balanceₘ₋₁ − Principalₘ
Extra payments go straight to principal, which reduces every future interest charge.
