When is refinancing worth it?
Refinancing is worth it when you'll stay in the home long enough to recover the closing costs through monthly savings, then enjoy net positive returns after that. Calculate your break-even period (closing costs ÷ monthly savings). If you plan to stay 2–3x past that point, it's typically a clear win.
What is the break-even point on a refinance?
It's the number of months it takes for your monthly savings to add up to your refinance closing costs. If closing costs are $4,500 and you save $300 per month, your break-even is 15 months. Beyond that point, every additional month of savings is pure benefit.
How much should rates drop before I refinance?
A common rule is at least 0.75–1.0% lower than your current rate. But the right number depends on your closing costs and how long you'll stay. With low closing costs and a long horizon, even 0.5% can pay off. With high closing costs and a short stay, even 1.5% may not. Run your specific numbers.
Should I roll closing costs into the loan?
Rolling closing costs into the loan avoids paying out of pocket but means you'll pay interest on those costs for the life of the loan. Paying upfront saves more long-term, but rolling them in is fine if you don't have cash on hand and your monthly savings still work after the slightly higher payment.
Does refinancing reset my loan term?
Yes — when you refinance into a new 30-year loan, you start over at year zero of a 30-year amortization, even if you'd already paid 5 or 10 years on the old loan. This is why total lifetime interest can go up even when your monthly payment drops. To avoid this, refinance into a shorter term that matches your remaining years.
What is a cash-out refinance?
A refinance where you borrow more than your current balance and take the difference as cash. Useful for renovations, consolidating higher-rate debt, or major expenses. Your new loan is larger, monthly payment may rise, but you tap home equity at typical mortgage rates — usually much lower than personal loans or credit cards.
How much does it cost to refinance?
Typically 2–5% of the loan amount in closing costs. On a $300,000 refinance that's $6,000–$15,000 total. Costs vary by lender, state, and loan size. Get loan estimates from at least three lenders to compare — fees can vary by thousands of dollars on the same loan.
Will refinancing hurt my credit score?
Slightly and temporarily. The hard inquiry typically drops your score by a few points, and opening a new loan account briefly affects credit age. Both effects fade within a year. Multiple mortgage inquiries within a 14–45 day window count as one inquiry for scoring purposes, so feel free to shop around.
Can I refinance if my home value dropped?
Possibly. If your loan-to-value ratio is now above 80%, you'll likely need PMI on the new loan and may face stricter terms. Government-backed streamline refinances (FHA, VA) may be available with reduced LTV requirements. If you're severely underwater, special programs sometimes exist for borrowers in good standing.
How long does refinancing take?
In the US, 30–45 days is typical from application to closing, sometimes faster for streamline refis and longer for cash-out. Provide documentation promptly and respond to lender requests within 24 hours to keep things moving. Lock your rate when you apply to protect against market changes during processing.
Should I pay discount points?
Discount points buy a lower rate — typically 1 point (1% of loan) lowers the rate by 0.25%. The math is the same as the refinance itself: how long to break even? If you'll keep the loan well past that point, points pay off. If you might refinance again or move soon, skip them.
How accurate is this refinance calculator?
The math is precise for your inputs. Real numbers depend on the exact terms your lender offers, which vary by credit, income, equity, and program. Use this to estimate the upside; then get loan estimates from a few lenders for exact numbers before deciding.
