Refinance Break-Even Calculator — When Do You Start Saving?

Separate payment break-even from five-year financing cost using entered rates, closing costs, payments, and ending balances.

Quick answer: Refinance break-even is closing costs divided by monthly savings. If you keep the loan past break-even, refinancing may pay off; if not, the costs can wipe out the savings.

About mortgage rates

Mortgage rates depend on loan type (30-yr fixed, 15-yr fixed, ARM, FHA, VA, jumbo), your credit score, down payment, points paid, loan amount, property state, and whether you're purchasing or refinancing. The calculator above uses a representative market rate for payment estimates — your actual rate will vary.

For a personalized rate comparison, use the tool below to see lenders ranked by APR, loan type, and your profile.

Frequently Asked Questions

Everything you need to know.

Which refinancing costs should I enter?
Use lender and third-party transaction costs from a Loan Estimate. Treat prepaid taxes, insurance, escrow funding, financed costs, credits, and points consistently when comparing offers.
What exactly is the "break-even point" in a refinance?
It's your entered closing costs divided by your monthly payment reduction, rounded up to the next whole month. If refinancing costs $5,000 and cuts your payment by $200/month, break-even is 25 months — the point where cumulative savings catch up to what you paid to refinance.
Why does the five-year comparison matter if I already know my break-even point?
Break-even only measures payment, not total cost. A refinance that resets your clock (e.g. 22 years remaining refinanced into a new 30-year term) can break even quickly on payment alone while still costing more in total interest and leaving you owing more principal after five years. The five-year comparison nets out each loan's projected ending balance so it isn't mistaking home equity for a cost.
Should I refinance if I'm planning to move in a few years?
Compare your break-even month against how long you realistically expect to stay. If break-even is 25 months and you plan to sell in 3 years, you'd net roughly 11 months of real savings — still worthwhile, but by a much thinner margin than the headline monthly savings number suggests.
Does this account for the interest rate on my new loan versus my current one?
Yes — enter both your current note rate and the new rate you're being offered. The calculator computes both payments independently using your entered remaining balance and term, so it reflects your actual rate spread rather than a generic assumption.
Is the Refinance Break-Even Calculator — When Do You Start Saving? free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the Refinance Break-Even Calculator — When Do You Start Saving? affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.
Are the results personalized financial advice?
No. Calculator outputs are educational estimates based on the inputs you enter. Review assumptions and confirm terms directly with providers before making a financial decision.
What should I do after seeing the result?
Use the recommendation module on this page to compare mortgage rates, or run Money Map to compare this home & mortgage decision with your other opportunities.
How does SwitchWize choose related offers?
Related offers are matched by the calculator surface (mortgage) and ranked using SwitchWize data such as rate, fees, trust signals, product fit, and switching friction. Paid relationships do not change organic ranking order.
How fresh are the rates and offers shown?
Rate and offer data is reviewed on a recurring cadence and every offer module shows review context or links to the methodology and disclosure pages.
Where can I see the ranking methodology?
The SwitchWize methodology page explains how rate freshness, editorial review, affiliate disclosure, and category ranking factors work.
Can Money Map use this result?
Yes. Money Map is the broader diagnostic path: it compares savings, mortgage, cards, and debt so you can see whether this calculator result is your highest-impact next move.

Why This Matters

A lower payment can come from restarting or extending the term. The five-year comparison includes ending principal so equity is not mislabeled as a cost.
