Refinancing is a math problem before it is a shopping problem. Closing costs typically run 2%–5% of the loan amount. Divide that by your monthly savings and you get the breakeven point — the number of months you must stay in the home for the refinance to pay for itself. Only after the math says yes does the lender comparison matter.
Refinance lender comparison
Rates change daily; collect same-day quotes. The four lender types for refinancers in 2026:
| Lender type | Typical rates | Closing costs | Speed | Best for |
|---|---|---|---|---|
| Online lender | Often the lowest | Low origination; verify points | 2–4 weeks | Rate-focused borrowers with clean files |
| Your current servicer | Rarely the best rate, sometimes retention offers | Occasionally discounted | Fast — they hold your file | Convenience; always benchmark against outside quotes |
| Credit union | Competitive for members | Low | 4–6 weeks | Members; jumbo or non-standard loans |
| Mortgage broker | Shops wholesale lenders on your behalf | Broker fee or built into rate | 3–5 weeks | Complex files and one-application shopping |
The breakeven calculation, worked
- Loan balance: $300,000. Rate drop: 7.0% → 6.0% on a 30-year term.
- Monthly principal-and-interest savings: roughly $200.
- Closing costs: $6,000 (2%).
- Breakeven: 30 months. Stay longer than 2.5 years and the refinance wins; move earlier and you paid $6,000 for savings you never kept.
Two adjustments people skip:
- Term reset. If you are 8 years into a 30-year mortgage and refinance into a new 30-year term, your payment drops partly because you are stretching the debt over 30 years again — not because the rate improved. Compare total interest over your remaining horizon, or refi into a 20-year term.
- Cash-out refinances convert home equity into debt at mortgage rates. That can beat credit card rates — but it puts your home on the line for spending that used to be unsecured. Treat it as a last resort, not a piggy bank.
Our guide to when refinancing makes sense walks through the decision framework in more detail.
Who this is NOT for
- Anyone inside the breakeven window. If you might move, sell or pay off the loan before breakeven, refinancing is a guaranteed loss — no lender is cheap enough to fix the math.
- Anyone with a small remaining balance. Closing costs do not shrink proportionally with the loan. On a $60,000 balance, even a full percentage point of rate savings rarely covers $3,000+ in costs.
- Anyone deep into their loan. In the final decade of a mortgage, payments are mostly principal. Restarting the amortization clock — even at a lower rate — can cost more total interest. Run the numbers for your actual remaining term.
- Anyone refinancing to fund consumption. Extending 25 years of debt to pay for a renovation you could save for is how equity quietly disappears.
Bottom line
Do the breakeven math first. If the answer is yes, collect three same-day quotes, compare APRs (not rates), and take the cheapest — the lender’s brand matters far less than the fee sheet.
Frequently asked questions
How much lower should my new rate be to make refinancing worth it?
The old rule of thumb was one full percentage point, but the real answer comes from the breakeven calculation: divide total closing costs by your monthly savings. If you will keep the loan well past that breakeven point, even a half-point drop can be worth it. If you will not, two points is not enough.
What are typical refinance closing costs in 2026?
Typically 2%–5% of the loan amount — roughly $6,000–$15,000 on a $300,000 loan — covering origination, appraisal, title and recording fees. No-closing-cost refinances exist, but the costs are paid via a higher rate, so compare the total interest over your expected time in the home, not just the upfront figure.
Should I refinance with my current mortgage servicer?
Only if they win on price. Current servicers sometimes offer streamlined or discounted refinances, especially for government-backed loans, and the process can be faster. But loyalty discounts in mortgages are rare — get two or three outside quotes and make your servicer beat them.
