How the numbers shift across typical situations for this calculator:
| Scenario | Months to break even |
|---|---|
| $4,800 cost · $200/mo | 24 |
| $6,000 cost · $150/mo | 40 |
| $3,000 cost · $250/mo | 12 |
| $9,000 cost · $300/mo | 30 |
How This Calculator Works
Enter the total closing costs of the refinance and the amount the new monthly payment saves you. The calculator divides one by the other to find the break-even month — the point after which the refinance is genuinely saving you money.
The Formula
Recovery Period
Fixed Cost is the upfront amount, Benefit per Period is the recurring gain that pays it back
Worked Example
A refinance with $4,800 of closing costs that lowers the payment by $200 a month breaks even at 24 months. Stay in the home beyond two years and the refinance pays off; leave sooner and it costs more than it saves.
Key Insight
A refinance only makes sense if you keep the loan past the break-even month. The headline rate drop matters less than how long you will stay — a low rate cannot recover closing costs you never hold the loan long enough to earn back.
The 1% rule and why it's outdated
Traditional rule: refinance when current rate is at least 1 percentage point below your existing mortgage rate. With current closing costs ($3,000-8,000) and the longer time it takes to amortize a refi, the rule is roughly correct for $300k+ loans but may not apply universally.
Better rule: calculate the break-even point — months until cumulative monthly savings exceed total refinance costs. Worked example: $400k mortgage at 7% (P&I $2,661), refinanced to 6% (P&I $2,398). Monthly savings: $263. Refi costs: $6,000. Break-even = $6,000 / $263 = 22.8 months. If you'll stay in the home 23+ months, refinancing is profitable. Less than that, you lose money.
Sensitivity: smaller loans need bigger rate drops to make refinancing worthwhile. On a $100k mortgage at 7% vs 6%: monthly savings only $66, break-even on $6k closing costs = 91 months (~7.5 years). For small loans, you often need 1.5-2 percentage point drops to make refinancing worth the trouble.
Closing costs: what's actually included
Refinance closing costs are typically 2-5% of loan amount. On a $400k refi: $8,000-20,000 in total costs. Major components: loan origination fee (0.5-1% of loan amount), appraisal ($500-800), title insurance ($1,000-3,000 — even though your home is the same, lender requires NEW title insurance), application fee ($200-500), credit report ($30-100), processing/underwriting fees ($1,000-2,000).
'No-closing-cost' refinances are NOT free — the costs are either (1) rolled into a higher interest rate (typically 0.25-0.5% above what you'd otherwise get), OR (2) added to the loan balance (you pay them with interest over the loan life). Both effectively pay the costs through the mortgage rather than upfront.
Math on no-closing-cost option: $400k refi at 6.0% with $6k closing costs paid upfront vs 6.5% no-closing-cost. Monthly payment difference: $138/month. If you stay long enough that 138 × months > 6000, the upfront option wins. Break-even: ~44 months. Stay less than 4 years, no-closing-cost saves money. Stay longer, paying upfront wins.
Cash-out refinance: the new equity-as-cash trade-off
Cash-out refinance: new mortgage > old mortgage balance, with the difference paid to you in cash. Rates 2026: typically 0.25-0.50% HIGHER than rate-and-term refis (lenders charge a premium for the increased risk).
Worked example: home value $500k, current mortgage $250k (LTV 50%). Cash-out refi to new mortgage $400k (LTV 80%). You receive $150k in cash. New monthly payment higher, total interest paid higher, but you have $150k for whatever purpose (renovation, debt consolidation, investment, college tuition).
When cash-out refi makes sense: (1) major home improvement that adds value (kitchen, addition — likely net positive), (2) consolidating very high-interest debt where the rate drop justifies the new mortgage (credit cards 22% → mortgage 7% can save substantial interest IF you don't run up cards again), (3) investment opportunity with high expected return (stocks at index returns 7-10% can beat mortgage rate at 7% — but at risk). When it DOESN'T: discretionary spending, vacations, cars — converting home equity to consumption is usually wealth-destroying.
Refinance break-even by rate drop and loan amount
Months until cumulative monthly savings exceed $6,000 in closing costs. Stay longer than break-even = refinancing worthwhile. Sell before = losing money.
| Rate drop | Savings on $200k loan | Break-even | Savings on $500k loan | Break-even |
|---|---|---|---|---|
| 0.5% | $60/mo | 100 months (8.3 yr) | $150/mo | 40 months (3.3 yr) |
| 1.0% | $120/mo | 50 months (4.2 yr) | $300/mo | 20 months (1.7 yr) |
| 1.5% | $180/mo | 33 months (2.8 yr) | $450/mo | 13 months (1.1 yr) |
| 2.0% | $240/mo | 25 months (2.1 yr) | $600/mo | 10 months |
Larger loans break even faster on smaller rate drops. Smaller loans need bigger drops to justify the same $6k closing costs. Always factor in expected time in home — if you might move within break-even period, refinancing loses money even on attractive rate drops.
Frequently Asked Questions
What is the refinance break-even point?
It is the number of months of payment savings needed to recover the closing costs of the refinance. Past that month, the refinance is saving you money.
What goes into closing costs?
Lender fees, appraisal, title, and any discount points paid to lower the rate. Enter the full upfront cost of completing the refinance.
How do I find my monthly savings?
Subtract the new monthly principal-and-interest payment from the old one. Compare like for like — principal and interest only, excluding escrow.
Should I refinance if I might move soon?
Only if you will stay past the break-even month. If a move is likely before then, the closing costs outweigh the savings.
Does extending the loan term affect this?
It can. A longer term lowers the monthly payment, which shortens the break-even, but it may raise total interest over the life of the loan.

Methodology & Review
The break-even month is the refinance closing costs divided by the monthly payment saving. Staying in the home past that month means the refinance has paid for itself.
