How Mortgage Overpayments Cut Years Off Your Loan
During the early years of a 30-year home mortgage, over 70% of every monthly payment goes straight toward interest charges rather than building principal home equity. Making extra monthly overpayments goes 100% toward reducing your principal balance, compounding interest savings across the remaining loan life.
Calculating the impact of mortgage overpayments shows how small extra contributions shave years off your payoff date.

Worked Example of a $250,000 Home Loan
Consider a homeowner with a $250,000 mortgage at a fixed interest rate of 6.0% with 25 years (300 months) remaining. The standard principal and interest payment is $1,610.75 per month.
Look at what happens when adding just $200.00 extra per month designated toward principal:
- Standard Total Interest Paid: $233,225.00 over 25 years
- Accelerated Total Interest Paid: $170,410.00 with overpayments
- Total Interest Saved: $62,815.00
- Time Saved Off Loan Term: 5 years and 4 months shaves off payoff date
Why Early Overpayments Count Most
Because interest compounds on your remaining principal balance, overpayments made in years 1 through 10 eliminate decades of future compounding interest. Even modest extra payments of $50 or $100 per month make a massive long-term difference.
