Free Home Refinance Calculator

Use this free refinance calculator to compare your current mortgage against a possible new loan. Estimate payment changes, refinance closing costs, break-even timing, and long-term savings before making a decision.

Compare Your Current Mortgage vs a Refinance

Refinancing can lower your payment in some cases, but it can also reset your loan term, add closing costs, or change mortgage insurance. This tool helps you compare both sides so you can see whether a refinance may actually help in your situation.

When a Home Refinance May Make Sense

A refinance may be worth considering if you can lower your interest rate, reduce your monthly payment, remove mortgage insurance, shorten your loan term, or improve your overall loan structure. But even then, the math depends on closing costs, how long you plan to stay in the home, and whether the refinance restarts the clock on your mortgage.

Important Things to Remember Before Refinancing

Lower Monthly Payments Are Not the Whole Story

A refinance can reduce your monthly payment while still increasing the total interest paid over time, especially if you restart into a longer loan term.

Closing Costs Matter

Refinancing usually comes with lender fees, title costs, and other charges. Those costs can reduce or delay your savings.

Mortgage Insurance Can Change the Math

PMI, MIP, VA funding fees, or USDA guarantee fees may affect the real benefit of refinancing depending on your loan type and equity position.

This Tool Is for Education Only

This refinance calculator is meant to help you understand the numbers. It is not a lender quote, tax opinion, or legal recommendation.

Common Refinance Questions

Is refinancing worth it if I only lower my rate a little?

Sometimes. It depends on your remaining loan balance, closing costs, new term length, and how long you expect to keep the home.

How do I estimate my refinance break-even point?

A basic break-even point compares your refinance closing costs to your monthly savings. This tool also helps you compare longer-term total cost differences.

Should I refinance into another 30-year mortgage?

That depends on your goal. A new 30-year loan may reduce your payment, but it can increase the total interest you pay over time.

Can refinancing remove PMI?

In some cases, yes. If you have enough equity, a conventional refinance may eliminate PMI. This tool helps estimate how that may affect the result.

Are property taxes and homeowners insurance included?

No. This calculator focuses mainly on principal, interest, mortgage insurance, and refinance costs because taxes and insurance often do not change much from the refinance itself.
