Refinance calculator

Compare your current loan with a refinance to estimate payment savings and break-even timing.

Use current balance, current rate, remaining term, new rate, new term, and closing costs to estimate whether refinancing lowers payments and saves money after fees.

This estimate compares current and refinanced amortized payments, then measures monthly savings, lifetime interest savings, and the closing-cost break-even point.

Why this result matters

What this calculator helps you answer

A refinance planning calculator focused on current-vs-new payment savings, closing costs, and break-even timing rather than generic mortgage origination or amortization alone. Use the tool above to enter a few clear inputs and get a practical answer you can use right away.

This refinance calculator compares current and refinanced loan payments, remaining interest cost, net savings after closing costs, and break-even timing. It stays distinct from mortgage and repayment calculators by focusing on the refinance decision itself.

Formula and method

How the calculation works

The calculator estimates current and refinanced amortized payments, compares remaining interest cost, subtracts closing costs from lifetime savings, and computes how many months of payment savings are needed to break even.

Example

Example refinance comparison

If a homeowner or borrower knows the current balance, remaining term, current rate, refinance offer, and closing costs, the calculator helps estimate whether the refinance actually improves cash flow and long-term cost.

FAQ

Common questions about this calculator.

Short answers to the questions people often ask before or after using the tool.

Question

Why does break-even matter?

Break-even shows how long it takes monthly payment savings to recover closing costs, which helps determine whether the refinance is worth doing if you may move or sell sooner.

Question

Can refinancing lower monthly payment but still cost more overall?

Yes. Extending the term can lower monthly payment while increasing total interest, which is why this page also compares lifetime interest and net savings after fees.

Question

How is this different from the mortgage calculator?

The mortgage calculator helps estimate an original loan. This page specifically compares an existing loan with a new refinance offer.
