Refinance Analysis Calculator

Analyzes whether a mortgage refinance makes financial sense.

Overview

Analyzes whether a mortgage refinance makes financial sense. Compares the current loan against the proposed refinance, computes current and new payment, monthly savings, break-even months, and gross and net savings over the hold horizon, then scores whether the refi economics are attractive. Use it as a rate-and-term refi calculator, break-even month calculator, closing-cost payback tool, or monthly payment savings estimator.
