Recasting Mortgage Calculator
What is a Recasting Mortgage Calculator?
A recasting mortgage calculator is a financial tool designed to show you how making a large, lump-sum payment towards your mortgage principal can lower your future monthly payments. When you recast a mortgage, your lender re-amortizes the loan based on the new, lower balance while keeping the interest rate and the original loan’s end date the same. This calculator helps you visualize the potential monthly savings and total interest reduction, empowering you to make an informed decision about your home loan.
The Recasting Mortgage Formula and Explanation
The core of a recast calculation involves determining the new monthly payment after a principal reduction. The standard formula for a monthly mortgage payment (M) is:
M = P [r(1+r)^n] / [(1+r)^n – 1]
When you recast, you first calculate your new principal (P’).
New Principal (P’) = Original Principal (P) – Lump-Sum Payment
Then, you use the same formula with the new principal but the *original remaining term (n)* and *interest rate (r)* to find the new monthly payment (M’). The calculator does this for you automatically. For a deeper dive into how this affects your loan, our amortization schedule calculator can be a helpful resource.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| P | Current Loan Principal | Currency ($) | $50,000 – $2,000,000+ |
| r | Monthly Interest Rate | Percentage (%) | 0.002 – 0.007 (monthly) |
| n | Remaining Loan Term | Months | 1 – 360 |
| L | Lump-Sum Payment | Currency ($) | $5,000+ |
Practical Examples of Mortgage Recasting
Example 1: Significant Inheritance
Imagine a homeowner has a $300,000 remaining balance on a 30-year mortgage at a 5% interest rate, with 25 years left. They receive an inheritance of $50,000 and decide to recast.

- Results:
- Original Payment: ~$1,753
- New Balance: $250,000
- New Payment: ~$1,461
- Monthly Savings: ~$292
Example 2: Bonus From Work
Another homeowner owes $450,000 with 28 years remaining at 6.5%. They get a $25,000 bonus and use it to recast their mortgage.
- Inputs:
- Current Balance: $450,000
- Interest Rate: 6.5%

Key Factors That Affect Mortgage Recasting
- Lump-Sum Amount: The larger the payment, the greater your monthly savings will be.
- Lender Policies: Not all lenders offer recasting. FHA, VA, and USDA loans are typically not eligible. You must confirm with your lender first.
- Recasting Fees: Most lenders charge a fee, usually a few hundred dollars, which is much lower than refinancing closing costs.
- Your Interest Rate: Recasting is most beneficial when you already have a low interest rate that you want to keep. If current rates are much lower, refinancing might be a better option.
- Payment History: Lenders usually require a history of on-time payments to approve a recast application.
- Minimum Payment: Lenders often require a minimum lump-sum payment, commonly between $5,000 and $10,000.
Frequently Asked Questions (FAQ)
- Is mortgage recasting a good idea?
- It can be an excellent idea if you have a lump sum of cash, like your current interest rate, and want to lower your monthly payments for better cash flow.
- How is recasting different from just making an extra payment?
- An extra payment shortens your loan term but keeps your monthly payment the same. Recasting keeps your term the same but lowers your monthly payment. Exploring a principal reduction calculation can clarify this further.
- How much does it cost to recast a mortgage?
- Fees are typically modest, ranging from $150 to $500, depending on the lender.
- How many times can you recast a mortgage?
- Policies vary, but many lenders allow you to recast multiple times, though you’ll pay the fee each time. Some may only allow it once.
- Does recasting hurt your credit score?
- No, recasting does not involve a credit check and therefore has no impact on your credit score.
- What’s the main benefit of recasting?
- The primary benefit is a lower monthly mortgage payment, which frees up cash flow, while also saving on the total interest paid over the life of the loan.
- When is refinancing better than recasting?
- Refinancing is better if current market interest rates are significantly lower than your current rate, as it allows you to secure that new, lower rate.
- How do I start the recasting process?
- The first step is to contact your current mortgage lender or servicer and ask if they offer mortgage recasting and what their specific requirements are.
