Mortgage Repayment Formula Explained
Mortgage repayments are calculated using the standard amortization formula.
Formula
Payment = P × r ÷ (1 − (1 + r)^(-n))
Where:
P = Principal loan amount
r = Interest rate per payment period
n = Total number of payments
This formula ensures each repayment covers both:
- Interest
- Principal
As the mortgage progresses:
- Interest gradually decreases.
- Principal repayment gradually increases.
