What Is a Mortgage Overpayment?
A mortgage overpayment means paying more than your required monthly mortgage amount. The extra money goes directly toward reducing your loan principal.
When your principal decreases faster:
- You pay less interest overall
- Your loan term shortens
- You build home equity quicker
Because mortgage interest is calculated on your remaining balance, lowering the balance early results in substantial long-term savings.

Example: How Overpaying Saves Money
Let’s look at a real-world example:
- Loan Amount: $300,000
- Interest Rate: 6%
- Loan Term: 30 years
- Monthly Overpayment: $250
Without Overpayment:
- Standard monthly payment calculated
- Full 30-year repayment
- Significant total interest paid over time
With $250 Monthly Overpayment:
- Mortgage paid off several years earlier
- Thousands saved in interest
- Faster financial freedom
Even a $100–$300 monthly overpayment can reduce your mortgage term by several years and save tens of thousands of dollars.
How the Mortgage Calculation Works
The calculator uses the standard mortgage amortization formula:
Monthly Interest Rate:
Annual Interest Rate ÷ 12
Standard Mortgage Payment Formula:
P × [r(1+r)^n] ÷ [(1+r)^n – 1]
Where:
- P = Loan Amount
- r = Monthly Interest Rate
- n = Total Number of Payments
When overpayments are added, the tool recalculates how quickly your balance reduces each month and determines your new payoff timeline.
