Mortgage Recast Calculator
Owning a home comes with long-term financial responsibilities, but there are strategies to make your mortgage more manageable without refinancing. One powerful option is a mortgage recast.
Our Mortgage Recast Calculator helps you see how much you can lower your monthly payments and save on interest by applying a lump-sum payment toward your mortgage balance and recalculating your loan.
What Is a Mortgage Recast?
A mortgage recast (sometimes called re-amortization) allows you to:
- Make a large lump-sum payment toward your mortgage principal.
- Ask your lender to recalculate monthly payments based on the new, lower balance.
- Keep the same interest rate and loan term.
Unlike refinancing, a recast doesn’t require credit checks, new loan closing, or high fees. It’s a straightforward way to reduce monthly payments while staying on track with your original loan.

The calculator helps you:
- ✅ See how much your monthly payment decreases after a lump sum.

Practical Example
Scenario:
- Loan Balance: $280,000
- Interest Rate: 6.5%
- Remaining Term: 25 years
- Lump-Sum Payment: $40,000

👉 By recasting, you save $270 per month and around $41,000 in total interest.
Benefits of a Mortgage Recast
- Lower Monthly Payments – Reduces financial stress without extending your loan term.
- Keep Your Interest Rate – No need to refinance in a high-rate environment.
- Save on Interest – Reduces total interest paid over the life of the loan.
- Low Cost – Most lenders charge only a small recast fee ($150–$500).
- No New Loan Application – Simpler than refinancing.
Things to Consider Before a Recast
- You need a large lump sum (from savings, bonus, inheritance, or property sale).
- Not all loans qualify (many government-backed loans like FHA, VA, USDA are excluded).
- Your lender must approve the recast.
- It doesn’t shorten the loan term—only reduces monthly payments.
Tips for Homeowners
- Ask your lender about minimum lump-sum requirements (often $5,000–$10,000).
- Use windfalls (bonuses, tax refunds, inheritance) for recasting.
- Compare recasting vs. making extra principal payments without a recast.
- If interest rates are much lower than your current loan, refinancing may save more.
Use Cases
- Retirees – Lower monthly expenses while keeping the same loan.
- Families – Free up cash flow for college, childcare, or other expenses.
- High-rate environment – Avoid refinancing into a higher rate.
- Property sale – Apply profits from selling another property toward a recast.
