Recast calculator

Mortgage Recast Calculator

See how a lump-sum principal payment could change your monthly payment if your lender allows a mortgage recast.

What this estimate means

A recast usually keeps your interest rate and remaining term, then recalculates payment on the lower principal balance. Your lender may charge a fee or require a minimum principal payment.

Recast vs refinance

A recast can lower payment without changing your rate. A refinance may change rate and term, but it can add closing costs and a new loan approval process.
