Will refinancing pay off? Break-even month + lifetime savings.

Refinancing makes sense when monthly savings × months-you-stay exceeds closing costs. ValiFit's refinance calculator shows the break-even month, total interest saved, and the optimal time to refinance based on current rates and your remaining loan balance. Includes cash-out refi math: new loan vs. equity extracted.
