What is the Loan Refinance Calculator?

The Loan Refinance Calculator helps you decide if breaking your current loan to take a new one at a lower interest rate is actually worth the closing costs and fees.

It analyzes values such as loan amount, interest rate, term, monthly payment and returns insight through outputs like monthly obligation, total interest, payoff timeline, savings opportunity.

This structure helps you compare alternatives, understand trade-offs, and identify whether your current strategy is aligned with your goals.

Frequently Asked Questions

A general rule of thumb is to refinance if the new interest rate is at least 1% to 2% lower than your current rate, and if you plan to keep the loan long enough to hit the 'break-even' point.

Refinancing usually costs money (fees). The break-even point is how many months it takes for your new, lower monthly payment savings to completely pay off those upfront fees.
