What is Mortgage Acceleration?
Mortgage acceleration is a strategy to pay off your home loan faster than the standard amortization schedule by making extra payments toward the principal balance. This reduces the total interest you'll pay and shortens your loan term significantly.
This calculator helps with:
- Payoff planning - Calculate how extra payments affect your mortgage timeline
- Interest savings - See exactly how much interest you'll save
- Budget optimization - Determine the best extra payment amount for your situation
- Goal setting - Plan how to become mortgage-free faster
- Comparison analysis - Compare different extra payment scenarios
How Extra Payments Work
Extra payments are applied directly to your principal balance, which has compounding effects:
Principal Reduction
Extra payments reduce the amount that earns interest, creating a snowball effect.
Interest Savings
Less principal means less interest charged each month.
Shorter Term
Faster principal reduction leads to earlier payoff date.
Equity Building
More of your payment goes toward building home equity.
Types of Extra Payments
Monthly Extra Payments
Consistent monthly extra payments provide the most predictable acceleration.
Annual Payments
Apply bonuses, tax refunds, or annual raises as lump-sum extra payments.
Bi-Weekly Payments
Make half your monthly payment every two weeks for 26 payments per year.

Frequently Asked Questions
Common questions about mortgage acceleration and extra payments
What is mortgage acceleration?
Mortgage acceleration is the process of paying off your mortgage faster than the standard schedule by making extra payments toward the principal balance, which reduces interest costs and shortens the loan term.
How do extra payments affect my mortgage?
Extra payments are applied directly to the principal balance, reducing the amount of interest you'll pay over time and shortening the total loan term. Even small extra payments can save thousands in interest.
What's the best way to accelerate my mortgage?
The most effective way is to make extra principal payments monthly. You can also make bi-weekly payments, round up payments, or apply bonuses and tax refunds to the principal.
How much interest can I save with extra payments?
Even $50-100 extra per month can save $10,000-50,000 in interest over a 30-year mortgage, depending on your interest rate and loan amount. Higher interest rates and larger extra payments yield greater savings.
Can I make extra payments on any mortgage?
Most conventional mortgages allow extra payments, but some loans have prepayment penalties. Always check your loan agreement. FHA and VA loans typically allow unlimited extra payments without penalties.
When should I start making extra payments?
Start as soon as possible. The sooner you begin, the more interest you'll save due to compound interest working in reverse. Even if you can only afford small amounts initially, consistency matters.
How does this calculator work?
Enter your mortgage details and desired extra monthly payment. The calculator shows your original payment schedule versus accelerated schedule, including time saved and interest savings.
Are there tax implications for extra payments?
Extra principal payments don't affect your mortgage interest deduction. You can still deduct the interest portion of your regular payments, but the tax benefits decrease as you pay down the loan faster.
