Mortgage Refinance Calculator
Estimate how a new mortgage rate, term and closing costs compare with your remaining loan. Use the same currency for every amount; this is an estimate, not a lender quote.
How do I compare a mortgage refinance?
Enter your current payoff balance, rate and months remaining, then the proposed refinance rate, term and closing costs. Choose whether fees are paid upfront or added to the new balance. Compare monthly payments, total modeled cost and the first month cumulative cash-flow savings cover upfront costs.
Frequently asked questions

Are my mortgage details uploaded?
No. The estimate runs in this browser. Do not enter account numbers or other sensitive identifiers.
Does a lower mortgage payment always mean I save money?
No. A longer term can lower the payment while increasing total interest or extending repayment. Compare both the monthly payment and total modeled cost.
How are closing costs handled?
Choose to pay them upfront or add them to the new balance. This estimate compares modeled cash flows and does not include escrow refunds, prepaid taxes, insurance or lender-specific charges.
Does this calculator use live mortgage rates?
No. You enter both rates and all fees. Results are estimates and are not an offer, approval decision or financial advice.
