Refinance Break-Even Calculator
Find out how long it takes to break even on a refinance — and whether it's actually worth it given how long you plan to stay.
Frequently Asked Questions
When does refinancing make sense?
Refinancing typically makes sense when you can lower your rate by at least 0.5–1%, you plan to stay in your home past the break-even point, and your closing costs are reasonable (usually 2–5% of the loan balance).
What are typical refinancing closing costs?
Closing costs typically run 2–5% of the loan amount. On a $300,000 loan, expect $6,000–$15,000. Some lenders offer 'no-closing-cost' refinances by rolling the costs into the rate.
What is the break-even point?
The break-even point is how many months it takes for your monthly savings to cover the closing costs you paid upfront. If you sell or move before that, refinancing wasn't worth it.
How does my credit score affect refinancing?
Your credit score directly affects the interest rate you'll qualify for. A score above 740 typically unlocks the best rates. Even a 0.25% rate difference can save tens of thousands over the life of a loan.
Should I do a cash-out refinance?
A cash-out refinance lets you borrow against your equity. It can be worth it for home improvements or paying off high-interest debt — but it resets your loan and increases what you owe, so run the numbers carefully.
How the refinance break-even calculation works
The break-even point is simple: divide your total closing costs by your monthly payment savings. If refinancing costs $6,000 in closing costs and saves you $200/month, your break-even is 30 months (2.5 years). If you stay in the home longer than that, refinancing saves you money. If you sell or move before 30 months, it was a net loss. The key insight most people miss: it's not about the interest rate drop — it's about how long you'll be in the home. A 1% rate drop with $10,000 in closing costs on a small loan balance may take 7+ years to break even.
What closing costs actually include when you refinance
Refinance closing costs typically run 2–5% of the loan amount and include: origination fee (0.5–1% of loan), appraisal ($300–$700), title search and insurance ($700–$1,500), credit report fee ($25–$50), recording fees ($100–$250), and prepaid interest for the days until your first new payment. On a $300,000 loan, total closing costs often land between $6,000 and $9,000. Some lenders offer "no-closing-cost" refinances that roll the costs into a slightly higher rate or add them to the loan balance — these make sense when you plan to move within a few years, since you avoid the upfront payment.
The rate drop rule of thumb — and when it breaks down
The old rule says "refinance when you can drop your rate by 1%." This is a rough heuristic at best. On a $500,000 loan, a 0.5% drop saves $208/month — you break even on $6,000 in closing costs in 29 months. On a $100,000 loan, a 1% drop saves only $58/month — you break even on the same $6,000 closing costs in over 8 years. Loan balance, remaining term, and closing costs all matter as much as the rate difference. Always calculate the actual break-even for your specific numbers rather than applying the rule of thumb.
Cash-out refinancing: when it makes sense (and when it doesn't)
A cash-out refinance replaces your existing mortgage with a larger one, giving you the difference in cash. Common uses: home improvements that increase property value, paying off high-interest debt (credit cards at 20%+ replaced by mortgage debt at 6–7%), or funding major expenses. The risk: you're converting unsecured debt to secured debt — if you can't make payments, your home is on the line. Cash-out refis also reset your amortization clock, meaning you pay more interest over the extended term. They make the most financial sense for home improvements with strong ROI (kitchens, baths, additions) or eliminating genuinely high-interest debt, not for lifestyle purchases.
