Recasting a mortgage, also known as mortgage reamortization, is a simple way to reduce your monthly mortgage payment by making a lump-sum principal payment. Unlike refinancing, recasting keeps your original interest rate and loan term intact. Our Recast Mortgage Payment Calculator on this website helps homeowners determine their new monthly payment quickly and accurately, making financial planning easier and more efficient.
This tool is ideal for borrowers who want to maintain the terms of their current mortgage while lowering monthly obligations and improving cash flow.
What Is Mortgage Recasting?
Mortgage recasting is the process of recalculating your monthly mortgage payment after applying a lump-sum payment toward the principal. The interest rate and loan term remain unchanged, making it a faster, simpler, and usually less expensive option than refinancing.
New Payment Formula:
New Payment = Remaining Principal × [r × (1 + r)^n] ÷ [(1 + r)^n − 1]
Where:
- r = monthly interest rate
- n = number of remaining months

Practical Example
Suppose:
- Current Mortgage Balance: $350,000
- Interest Rate: 4.25%
- Remaining Term: 30 years (360 months)
- Lump-Sum Payment: $50,000
Step 1: Remaining principal = $350,000 − $50,000 = $300,000
Step 2: Monthly interest rate = 4.25 ÷ 12 = 0.003542
Step 3: Calculate new payment → approximately $1,474/month
This demonstrates a significant reduction from the original payment of $1,718/month, improving monthly cash flow.
