Most homeowners think the only way to reduce monthly mortgage payments is by refinancing. But there’s another powerful option: reamortization, also known as loan recasting.
Unlike refinancing, which creates a new loan with new terms, reamortization recalculates your monthly payments based on your existing interest rate, loan balance, and remaining term.
A Reamortization Calculator helps you estimate new monthly payments after making a large lump-sum payment toward your loan’s principal. It’s the easiest way to see how much you can save without the hassle of refinancing.
What is Reamortization?
Reamortization (loan recasting) is the process of recalculating your mortgage payment schedule after you make a significant payment toward your principal.
- Your interest rate stays the same.
- Your loan term stays the same (unless the lender allows adjustments).
- Your monthly payment decreases because the loan balance is reduced.
When to Use a Reamortization Calculator
- You received a large bonus, inheritance, or settlement and want to apply it to your loan.
- You sold another property and want to pay down this mortgage.
- You want lower monthly payments without refinancing.
- You plan to stay in your home long-term and don’t need a new interest rate.
How the Reamortization Calculator Works
The calculator requires just a few key details:
- Current Loan Balance – How much you still owe on your mortgage.
- Interest Rate – The fixed interest rate on your loan.
- Remaining Loan Term – How many years/months are left on your loan.
- Lump-Sum Payment – The extra payment you’re making toward principal.
After entering this information, the calculator will show you:
- New monthly mortgage payment.
- Savings per month compared to your old payment.
- Total interest savings over the life of the loan.
Step-by-Step Instructions
- Enter Current Loan Balance
Example: $250,000 remaining balance. - Input Interest Rate
Example: 5% fixed rate. - Enter Remaining Loan Term
Example: 25 years left. - Add Lump-Sum Payment
Example: $50,000 one-time payment. - Click “Calculate”
Instantly see your new reduced monthly payments and lifetime interest savings.
Practical Example
Imagine you have a mortgage with these details:
- Loan Balance: $250,000
- Interest Rate: 5%
- Remaining Term: 25 years
- Lump-Sum Payment: $50,000
Results:
- Old Monthly Payment: $1,462
- New Loan Balance: $200,000
- New Monthly Payment (same 25-year term): $1,169
- Monthly Savings: $293
- Lifetime Interest Savings: $50,000+
👉 By using reamortization, you keep the same interest rate but reduce your monthly payment by nearly $300 without refinancing.
