Recast Calculator
If you’re looking for a smart way to reduce your monthly mortgage payments without going through the hassle of refinancing, a Recast Calculator is exactly what you need.
Mortgage recasting allows homeowners to make a large principal payment and then recalculate their loan based on the new balance. The result? Lower monthly payments, reduced interest costs, and improved financial flexibility—all without changing your interest rate or loan terms.
This comprehensive guide explains how the recast calculator works, how to use it, practical examples, and expert strategies to maximize your savings.
What is Mortgage Recasting?
Mortgage recasting (also known as loan recasting) is the process of making a large lump sum payment toward your loan principal and then having your lender re-amortize the remaining balance.
Unlike refinancing:
- Your interest rate stays the same
- Your loan term remains unchanged
- You avoid closing costs and credit checks
Instead, your monthly payment is recalculated based on a lower balance.
