See how extra mortgage payments can save thousands in interest and dramatically reduce your loan term. Compare standard payments vs. accelerated payoff strategies.
Our extra payment calculator simulates two parallel amortization schedules — one with standard payments and one with additional payments — to show you exactly how much you can save. It runs a month-by-month calculation for precise results.
See the exact dollar amount of interest you'll save by making extra payments toward your principal.
Discover how many years and months you can shave off your loan term with consistent extra payments.
Choose from monthly, quarterly, yearly, or one-time extra payments to match your financial strategy.
Directly compare standard vs. accelerated payoff side-by-side with a detailed amortization schedule.
With extra payments, the principal portion increases, reducing the remaining balance faster and saving future interest.
This shows the total dollar savings from making extra payments over the life of the loan.
The earlier you start making extra payments, the more interest you save. Extra payments made in the first few years have the most impact.
Round your monthly payment to the nearest $50 or $100. Small rounding can save thousands over the life of a 30-year mortgage.
Instead of one monthly payment, pay half every two weeks. This results in 26 half-payments (13 full payments per year) — one extra payment annually.
Apply tax refunds, bonuses, or inheritance as one-time extra principal payments to make a significant dent in your balance.
If you have multiple debts, prioritize extra payments on the highest interest rate loan first for maximum savings.
Some loans have prepayment penalties. Check your loan agreement before making extra payments to avoid unexpected fees.
Extra payments provide the biggest savings on loans with high interest rates (7%+), where more of each payment goes to interest.
30-year mortgages benefit enormously from extra payments because the interest compounds over a longer period.
Ensure you have 3-6 months of expenses saved before accelerating loan payments. Liquidity is important.
If your loan interest rate exceeds expected investment returns, paying down debt becomes the better financial move.
Our Extra Payment Calculator is designed to help homeowners and borrowers understand the financial impact of making additional principal payments. By comparing standard amortization against accelerated payoff schedules, you can see exactly how much interest you'll save and how much sooner you'll be debt-free.
Month-by-month amortization iterations provide accurate interest savings and term reduction estimates.
Compare monthly, quarterly, yearly, and one-time extra payment strategies side-by-side.
