New Estimated Monthly Payment
What Is a Mortgage Recast?
A mortgage recast, sometimes called a re-amortization, is when a homeowner makes a large one-time payment toward their mortgage principal. Instead of refinancing, the lender recalculates the monthly payment based on the new, lower balance while keeping the original interest rate and remaining term intact.
Benefits of mortgage recasting include:
- Lower monthly payments without refinancing
- Reduced interest over time
- Retention of current low interest rates
- Minimal fees compared to refinancing
How the Rocket Mortgage Recast Calculator Works
The calculator uses the basic amortization formula to estimate new monthly payments after a lump sum payment is applied:MonthlyPayment=1−(1+MonthlyInterestRate)−TotalMonthsNewPrincipal×MonthlyInterestRate
Where:
- New Principal = Current Mortgage Balance – Lump Sum Payment
- Monthly Interest Rate = Annual Rate ÷ 12
- Total Months = Remaining Term × 12
This ensures accurate estimates based on your mortgage details.
How to Use the Rocket Mortgage Recast Calculator
Using the calculator is straightforward. Here’s a step-by-step guide:
Step 1: Enter Current Mortgage Balance
Provide your remaining mortgage balance. Example: $250,000.
Step 2: Input Annual Interest Rate (%)
Add your current mortgage interest rate. Example: 4.5%.
Step 3: Enter Remaining Term (Years)
Include the remaining years on your mortgage. Example: 25 years.
Step 4: Input Lump Sum Payment
Enter the amount you plan to pay toward the principal. Example: $10,000.
Step 5: Click “Calculate”
The calculator will instantly display your new estimated monthly payment.
Step 6: Copy or Share Results
You can copy the results to your clipboard or share them with others directly from the calculator.
Practical Example
Scenario:
- Current Mortgage Balance: $300,000
- Interest Rate: 5%
- Remaining Term: 30 years
- Lump Sum Payment: $20,000
Calculation:
- New Balance = $300,000 – $20,000 = $280,000
- Monthly Interest Rate = 5% ÷ 12 = 0.0041667
- Total Months = 30 × 12 = 360
Estimated new monthly payment = $1,502.38
Impact:
- Original monthly payment (before lump sum) = $1,610.46
- Monthly savings = $108.08
- Annual savings = $1,297
This example shows how a single lump sum payment can reduce your monthly obligations while maintaining the same interest rate and term.

Frequently Asked Questions (FAQs)
1. What is mortgage recasting?
Mortgage recasting is paying a lump sum toward your mortgage principal to lower monthly payments while keeping your original interest rate and term.
2. How is it different from refinancing?
Refinancing replaces your current mortgage with a new one, often with a new rate or term, while recasting simply recalculates payments on the existing loan.
3. Can I recast any mortgage?
Most conventional loans allow recasting, but some FHA, VA, or special programs may not. Always check with your lender.
4. How much does recasting cost?
Lenders typically charge a fee ranging from $150 to $500, which is usually much lower than refinancing costs.
5. Does recasting shorten my loan term?
Recasting generally keeps your term the same but reduces monthly payments. However, making additional principal payments can shorten the term.
6. Will recasting reduce total interest paid?
Yes, by lowering your principal balance, you pay less interest over the remaining term.
7. Can I recast multiple times?
Many lenders allow multiple recasts, but each may require a fee and approval.
8. Is a lump sum required?
Yes, recasting requires a minimum lump sum payment, typically a few thousand dollars depending on your lender.
9. How do I know if recasting is right for me?
If you want lower monthly payments and have extra funds to reduce principal without refinancing, recasting is ideal.
10. Does recasting affect my credit score?
No, recasting doesn’t impact your credit score because it doesn’t create a new loan.
11. How soon after a lump sum can I recast?
Lenders usually allow recasting once the payment clears and is applied to the principal, often within 30–60 days.
12. Can I recast my mortgage online?
Some lenders offer online recast requests; others may require in-person or phone applications.
13. Will recasting affect my escrow account?
Monthly payments may decrease, which can reduce the amount needed for taxes and insurance if escrow is included.
14. How much can I save by recasting?
Savings depend on the lump sum amount, interest rate, and remaining term. Even moderate payments can yield significant monthly reductions.
15. Do all lenders offer recasting?
Not all lenders offer recasting, but many conventional mortgage lenders do. Confirm with your bank or mortgage servicer.
16. Can I recast if I’m behind on payments?
Typically, lenders require your mortgage to be current before approving a recast.
17. Is recasting beneficial for short-term loans?
It’s more impactful on long-term mortgages since it reduces total interest over time.
18. Does recasting reduce principal?
Yes, your lump sum directly lowers your principal balance.
19. How is monthly payment recalculated?
Lenders use the remaining balance, interest rate, and term to determine new payments.

Absolutely. This strategy maximizes interest savings and accelerates mortgage payoff.
