How do I calculate refinance break-even?

Break-even months = closing costs ÷ monthly payment savings. If a refi cuts payment by $200/month and closing costs $4,800, break-even = 24 months. Below that, you lose money; beyond it, you save.

How much should mortgage rates drop to refinance?

The old "1% rule" — refi when rates drop 1.0 point below your current — is a useful starting heuristic. With faster online lenders and lower closing costs in 2026, even 0.5-0.75 point drops can be worthwhile if you stay 3+ years.

What is a no-cost refinance?

No-cost (lender-paid) refis charge zero closing costs but in exchange give a 0.125-0.375 pt higher rate. The lender pays your costs out of the rate spread (yield-spread premium). Break-even is immediate but the loan is higher-rate forever.

What is the difference between rate-and-term and cash-out refi?

Rate-and-term refi changes interest rate or loan length only — no cash withdrawal. Cash-out refi increases the loan balance above the payoff to put cash in your pocket (typically for home improvements). Cash-out rates are 0.125-0.25 pt higher than rate-and-term.

Do I need a new appraisal to refinance?

Conventional refis usually require an appraisal ($500-700). FHA Streamline and VA IRRRL (Interest Rate Reduction Refinance Loan) waive the appraisal entirely. Fannie Mae and Freddie Mac also offer Property Inspection Waivers (PIW) for low-LTV refis with strong borrower profiles.

How much does it cost to refinance?

Typical refi closing costs are 2-5% of the new loan amount. On a $300k refi, expect $6,000-$15,000. Lender fees are usually $2,000-3,500; title insurance $1,500-3,000; appraisal $500-700; recording + transfer tax variable by state.

Can I refinance to a 15-year mortgage?

Yes. 15-year refis carry rates 0.5-0.75 pt below 30-year. The monthly payment is higher (less amortization), but lifetime interest is dramatically lower. Common move for borrowers 5-7 years into a 30-year with rising income who want to be mortgage-free by retirement.

Should I roll closing costs into the refi loan?

You can, but you pay interest on those costs for 15-30 years. Better practice: pay closing costs out of pocket if you have cash, or take a slightly higher rate (no-cost refi) so the lender absorbs them. Rolling in is the worst of three options for long-term cost.

Will refinancing hurt my credit score?

Briefly. The hard credit pull and new account can drop your score 5-15 points. Per FICO scoring rules, mortgage inquiries within a 14-45 day shopping window count as ONE inquiry. The score recovers within 6-12 months as the new account ages.

What is an FHA Streamline refinance?

FHA Streamline (24 CFR 203.43) lets existing FHA borrowers refinance into a new FHA loan without an appraisal, income verification, or credit check beyond payment history. Lower closing costs ($1,500-3,000 typical), faster process. New rate must produce a "net tangible benefit".

VA Interest Rate Reduction Refinance Loan (38 U.S.C. §3710(a)(8)). Streamline refi for VA loans — no appraisal, no income re-verification. Funding fee is 0.50%, lower than the 2.15-3.30% on a regular VA purchase or cash-out refi. New loan must drop rate or convert ARM → fixed.

When should I NOT refinance?

When you are within 2-3 years of break-even and may sell. When rates are not meaningfully lower (<0.5 pt). When closing costs eat the savings. When you would extend the loan term backward (5 years into a 30 → fresh 30 erases prior amortization). When credit has dropped since origination.

Refinance Break-Even Calculator

The break-even month on a refi is closing costs ÷ monthly payment savings. Below the break-even month, you lose money. Above it, every month is pure savings. The chart shows the crossover precisely — and shades the loss zone red and gain zone green.

From the 1933 HOLC to the 2026 IRRRL: a century of mortgage refinance

In 2026, a Phoenix homeowner who locked a 7.5% mortgage in 2023 watches rates touch 6.0% and pulls up this calculator. With a $285k balance and $4,500 closing costs, the break-even comes in around 24 months — beating the industry rule of thumb. The visual crossover from red loss zone to green savings zone is the single most useful chart in residential lending.

The Home Owners' Loan Corporation (HOLC), created by the Home Owners' Loan Act of 1933, invented the modern American refinance. HOLC refinanced over 1 million distressed mortgages between 1933 and 1936, converting short-term balloon loans into 15-25 year fully-amortizing ones. The 30-year FHA mortgage (Title II National Housing Act 1934) was the direct descendant.

The Federal Housing Administration (FHA) introduced the FHA Streamline refinance in the 1980s — codified at 24 CFR 203.43. The streamline waives appraisal, income re-verification, and credit re-check; the only requirement is a "net tangible benefit" (rate drop, payment reduction, or ARM → fixed). FHA Streamline is the cheapest mainstream refi product as of 2026.

The Servicemen's Readjustment Act of 1944 (GI Bill) created the VA loan; its refinance cousin is the VA IRRRL (Interest Rate Reduction Refinance Loan, codified at 38 U.S.C. §3710(a)(8)). IRRRL drops the funding fee to 0.50% — the lowest on any VA product — and matches FHA Streamline's no-appraisal, no-credit-re-verify model.

The PMI Cancellation Act of 1998 (Homeowners Protection Act, 12 U.S.C. §4901-4910) does not directly govern refinances, but it interacts: a refi can eliminate PMI on a conventional loan if the new LTV is below 80% (based on a new appraisal), even if HPA auto-cancellation has not yet been triggered. Many homeowners refi specifically to drop PMI when home values have appreciated.

The Tax Cuts and Jobs Act of 2017 reduced the mortgage interest deduction cap to $750,000 of acquisition debt (was $1M pre-2018), and removed the deduction for home-equity interest unless used for home improvement. Cash-out refi tax treatment now depends on use of proceeds — investment property cash-outs deduct interest under IRC §163(d), home improvement under §163(h)(3), but personal use does not.

The CFPB's TRID rule (effective Oct 3, 2015 per Reg Z 1024.37) governs the Loan Estimate and Closing Disclosure on every refinance. The Loan Estimate must be issued within 3 business days of application; the Closing Disclosure 3 business days before closing. The break-even math on this page uses the closing-cost total disclosed on those forms. As of 2026, Rocket Mortgage, loanDepot, and Better.com offer fully online refi closings using e-notarization in 39 states under the SECURE Notarization Act of 2024.

How to evaluate a refinance

Get current balance + rate. Pull from your most recent statement; rate from your note.
Shop new rate. Compare 3+ Loan Estimates within a 14-day FICO shopping window — counts as one inquiry.
Get closing costs total. Section J of the new Loan Estimate (TRID-mandated since 2015).
Compute break-even. Closing costs ÷ monthly payment savings (same term). Below the line is loss, above is pure savings.
Compare to stay duration. Will you be in the home longer than break-even months? If yes, refinance pays.

“The lifetime interest savings calc is what most refi calculators miss. This one nails it — showing both same-term apples-to-apples and rolled-in scenarios. CFPB-compliant treatment of the no-cost refi tradeoff. Excellent compliance-friendly tool.”

“The 30→15 yr preset is the scenario I run with clients twice a week and the numbers match my own spreadsheets to the penny. The visual makes break-even click instantly — most clients have never seen this comparison done well.”

“No-cost refi FAQ correctly explains yield-spread premium math — many calculators get this wrong by claiming "truly free". CFPB-aligned. The 14-45 day FICO shopping window note is also accurate per FICO 9/10 specifications.”
