Our mortgage recast calculator helps homeowners easily estimate their new, lower monthly payments after making a large lump sum payment toward their existing loan balance. Using a recast calculator, you can plan your mortgage strategy more effectively and understand how a one-time payment impacts your loan term and overall costs.

What is Mortgage Recast?

In banking, a mortgage is a borrower's loan to purchase land, a plot, a house, or other real estate. The Recast Mortgage is a process where large payments are made to reduce the principal amount, so the lender re-amortizes the loan with lower monthly repayments based on the new balance.

Mortgage Recast Calculator

Though the loan is recast, the interest doesn't change and remains fixed. The loan term also stays the same. FHA, USDA, and VA loans typically do not support standard recasting, though lenders may make exceptions. For more details, see the Consumer Financial Protection Bureau.

How a Mortgage Recast Works

The borrower pays a lump sum toward the principal. The lender then re-amortizes the remaining balance into new monthly payments over the same remaining term. The new schedule includes updated principal, interest, and balance for every month ahead.

How to Use This Calculator

Enter: original loan amount, interest rate, loan term, months already paid, lump-sum payment, and recast fee. The calculator instantly shows your new EMI, interest saved, break-even point, and a full month-by-month amortization table.

Example: $200,000 loan at 5% for 30 years = $1,074/month. After 10 years, recast $50,000 (fee $250). New balance $112,684 → new payment $744/month for the remaining 20 years.

Requirements

  • No government-backed loan (FHA, VA, USDA not eligible)
  • Must meet lender's minimum equity requirements
  • Minimum lump-sum amount (varies by lender)
  • Good payment history required

When is the Right Time to Recast?

Recasting works best when your interest rate is fixed or rising, you have a low credit score that would hurt refinancing rates, or you've received a windfall (bonus, inheritance, asset sale) and want to lower monthly payments without the approval process of a refinance.

Loan TypeApprox. Rate

Refinance RatesSimilar (lender-dependent)

Rates change frequently based on inflation, Federal Reserve policies, and market demand.

Conclusion

Mortgage recasting lowers your monthly payments by applying a lump sum to the principal — keeping your rate and term unchanged. It's a smart, low-friction alternative to refinancing, especially when credit scores are low or rates are high. Use this calculator to see your exact numbers before approaching your lender.

Frequently Asked Questions

A Recast mortgage calculator helps homeowners estimate new monthly payments and total interest savings after making a lump sum payment towards their mortgage principal.
Recasting is the process of pre-paying a lump sum amount to the lender, which reduces the principal and gives a new, lower payment schedule.
When you recast, your lender charges a one-time administrative fee to redo your payment schedule. This typically falls between $150 and $500 — check with your lender for the exact amount.
No. The interest rate remains constant during recasting — only the monthly payment amount decreases due to the lower principal balance.
Government-backed loans — FHA, VA, and USDA — are generally not eligible for loan recasting.
Recasting is ideal when your interest rate is fixed or rising, your credit score is low (making refinancing expensive), or you've received a large sum you want to put toward your home without going through a full refinance process.
