Recasting Calculator

A Recasting Calculator is an essential tool for homeowners looking to reduce their monthly mortgage payments without refinancing. Mortgage recasting allows you to make a lump-sum payment toward your principal, after which your lender recalculates your monthly payments based on the new balance. Unlike refinancing, recasting usually comes with minimal fees, no credit check, and keeps your existing interest rate intact.

How to Use the Recasting Calculator

Using a Recasting Calculator is straightforward. The tool requires three essential inputs:

1. Current Mortgage Balance – The remaining amount owed on your loan.
2. Lump Sum Payment – The extra principal you plan to pay to reduce the balance.
3. Current Interest Rate – The fixed or adjustable rate of your mortgage.
4. Remaining Loan Term – The number of months or years left on your mortgage.

After inputting these values, the calculator provides the new monthly payment amount and the total interest savings over time.

Calculation Logic

The Recasting Calculator works using this formula:$$\text{New Monthly Payment} = \frac{(\text{Current Balance} – \text{Lump Sum}) \times r}{1 – (1 + r)^{-n}}$$New Monthly Payment=1−(1+r)−n(Current Balance−Lump Sum)×r​

Where:

• $r$r = monthly interest rate (annual rate ÷ 12)
• $n$n = remaining months in the loan term

This calculation recalculates your monthly payment based on the reduced principal while keeping your loan term and interest rate unchanged.

Practical Example

Suppose you have a mortgage of $300,000 with a 4% interest rate and 20 years remaining. You decide to make a $50,000 lump-sum payment.

• Current balance: $300,000
• Lump sum: $50,000
• Interest rate: 4%
• Remaining term: 20 years

Using the Recasting Calculator, your new monthly payment reduces from $1,819 to approximately $1,512, saving you hundreds of dollars each month while preserving your original loan terms.

• Minimal Fees: Most lenders charge $250–$500, far less than refinancing.
