Mortgage Recast vs Refinance

Want a lower required payment after a big principal hit? You have two common paths: recast the loan you already have, or refinance into a new one. They are easy to mix up. A recast keeps your rate and usually your maturity date; a refinance replaces the whole loan. Compare estimated numbers in the recast vs refinance vs extra payment calculator.

Recast: same loan, new payment math

After a large principal payment, some servicers will re-amortize the remaining balance over the remaining term at the same interest rate. The required monthly payment falls because the principal is lower. Rate and maturity date typically stay put. A fee is common. Not every loan program or servicer offers a recast — confirm before you count on one.

Refinance: new loan, new terms

Refinancing closes a new mortgage that pays off the old one. Rate and term can improve or worsen cash flow and total interest. Closing costs may be paid in cash or financed into the new balance. Qualification depends on credit, income, equity, and lender overlays. For cost recovery timing, use the refinance calculator and the refinance break-even guide.

Pick by goal, not by buzzword

Goal is a lower required payment and your rate is already fine? A recast (when available) can skip new underwriting and a rate change. Goal is a lower rate or a different term length? Refinance is the tool that can change those — at the cost of closing expenses and a new loan. A lump-sum payment without a recast usually does not lower the required installment; it mainly shortens payoff. Model that path in the extra payment calculator.

What this guide cannot promise

It does not list which lenders allow recasts. Servicer policies and investor rules change. Treat calculator outputs as educational estimates, not approval or advice.
