Reamortize Mortgage Calculator

Homeowners looking to reduce monthly mortgage payments without refinancing can benefit from reamortization, also called mortgage recasting. Our Reamortize Mortgage Calculator on this website allows you to quickly determine your new monthly payment after making a lump-sum principal payment, helping you plan finances efficiently and save on interest over time.

Reamortizing a mortgage spreads the remaining balance over the existing term, lowering your payment while maintaining your original interest rate.

What Is Mortgage Reamortization?

Mortgage reamortization is the process of recalculating monthly payments after paying down part of your mortgage principal. Unlike refinancing, reamortization does not require a new loan or new interest rate, making it faster and often cheaper.

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 Balance: $250,000
• Interest Rate: 3.75%
• Remaining Term: 25 years (300 months)
• Lump-Sum Payment: $30,000

Step 1: Remaining principal = $250,000 − $30,000 = $220,000

Step 2: Monthly interest rate = 3.75 ÷ 12 = 0.003125

Step 3: Calculate new payment → approximately $1,146/month

This demonstrates a significant reduction from the original monthly payment.
