Mortgage Repayment Formula
Mortgage repayments are calculated using the standard amortization formula:
Payment = P × r × (1 + r)^n ÷ [(1 + r)^n − 1]
Where:
P = Loan amount
r = Interest rate per payment period
n = Total number of payments
This formula ensures each payment covers both principal and interest until the loan is fully repaid.
Formula Breakdown
Let's understand each variable.
Loan Amount (P)
The original amount borrowed from the lender.
Example:
$250,000
Interest Rate (r)
The annual interest rate converted into the payment frequency.
For monthly payments:
Annual Rate ÷ 12
For bi-weekly payments:
Annual Rate ÷ 26
For weekly payments:
Annual Rate ÷ 52
Number of Payments (n)
Calculated as:
Loan Term × Payment Frequency
Example:
30 years × 12 months = 360 payments
Mortgage Calculation Example
Suppose you borrow:
Loan Amount: $350,000
Interest Rate: 5.5%
Loan Term: 30 years
Payment Frequency: Monthly
The calculator estimates:
- Monthly Payment
- Total Payments: 360
- Total Amount Paid
- Total Interest Paid
Changing the payment frequency to bi-weekly or weekly may reduce interest costs depending on your repayment strategy.
