FAQ

What makes this refinance calculator different?

It tests breakeven against how long you expect to keep the new loan and shows the effect of rolling costs into the refinanced balance.

Should I refinance if the monthly payment is lower?

Not automatically. A lower payment can still be a poor move if closing costs, points, or a longer term erase the benefit before you sell or refinance again.

Does this replace a lender Loan Estimate?

No. Use it for planning, then verify the rate, APR, closing costs, points, escrow, and cash-to-close with a lender.
