Mortgage Recast Calculator
Calculate your new monthly payment after making a lump sum payment to reduce your loan balance (recasting).

Frequently Asked Questions
Does recasting change my interest rate?
No. Recasting keeps your existing rate and term date. It only lowers the principal and monthly payment.
Is recasting better than paying extra principal?
Paying extra principal shortens the loan but keeps payments the same. Recasting lowers payments but keeps the term length. Choose based on cash flow needs.
