Decide whether refinancing a loan is actually worth it. Enter your current loan balance, interest rate and remaining term, then the new rate, new term and any closing costs, and the calculator compares the two side by side. It shows your new monthly payment, how much lower or higher it is than now, the total interest under each option, and the break-even month where your monthly savings finally outweigh the closing costs you paid. That break-even figure is the number most people forget, and it decides whether a refinance saves money or just moves it around, especially if you might sell or move before you reach it. Test different rates and terms to find the real deal. All math runs locally in your browser.
It compares your current monthly payment against the new rate and term, showing the monthly saving and total interest difference over the life of the loan.
It is how many months of savings it takes to recover any refinancing costs, after which refinancing starts paying off.
Not always. A longer new term can lower the payment but raise total interest, which is why the lifetime interest comparison matters.
