Should You Refinance Your Mortgage in 2026? How to Calculate If It Makes Sense
Refinancing replaces your current mortgage with a new one, typically to get a lower interest rate, change your loan term, or access home equity. The key question is whether the interest savings exceed the closing costs (typically 2-5% of the loan amount). If you can lower your rate by 0.75%+ and plan to stay in the home long enough to pass the break-even point, refinancing usually makes sense.

The Break-Even Formula: When Refinancing Pays Off
The most important number in any refinance decision is the break-even point — the month when your cumulative interest savings exceed your closing costs. The formula is straightforward: closing costs divided by monthly savings equals months to break even.
For example, if refinancing costs $6,000 in closing costs and saves you $200/month in interest, you break even in 30 months (2.5 years). If you plan to stay in the home for 5+ more years, this is a clear win. If you might move in 2 years, it is not.
Our Refinance Calculator computes your exact break-even point, total interest savings over the life of the loan, and new monthly payment. Our 15 vs 30-Year Comparison shows what switching term lengths does to your total cost.
When Refinancing Makes Sense
The traditional rule was to refinance when rates drop at least 1% below your current rate. Today, most experts say 0.5-0.75% is sufficient because closing costs have become more competitive. On a $300,000 loan, a 0.75% rate reduction saves roughly $150/month and $54,000 over 30 years.
Beyond rate reduction, refinancing makes sense to switch from an adjustable-rate to a fixed-rate mortgage (locking in certainty), to shorten your term from 30 years to 15 years (builds equity faster, less total interest), to remove PMI if your home has appreciated past 20% equity, or to do a cash-out refinance for home improvements with strong ROI.
Refinancing does not make sense if you are close to paying off your mortgage (most savings come in early years), if you plan to move within 2-3 years (will not pass break-even), or if your credit score has dropped significantly since your original mortgage.
What Refinancing Costs
Closing costs for a refinance typically run 2-5% of the loan amount. On a $300,000 mortgage, expect $6,000-$15,000. Major cost components include the appraisal fee ($300-$600), origination fee (0.5-1% of loan), title insurance ($500-$1,500), recording fees, and credit report fee.
Some lenders offer "no-closing-cost" refinances, but these typically roll costs into the loan balance or charge a slightly higher rate. You are still paying — just not upfront. Use our Closing Cost Calculator to estimate your specific costs.
When comparing lenders, request the Loan Estimate form from each. This standardized document breaks down every fee and makes comparison straightforward. Get quotes from at least 3 lenders — rates can vary by 0.25-0.5% between lenders on the same day.
How to Get the Best Refinance Rate
Your credit score is the single biggest factor in your refinance rate. A score above 760 qualifies for the best rates. Each 20-point drop typically adds 0.125-0.25% to your rate. Check your credit report for errors before applying — correcting mistakes can boost your score significantly.
Your loan-to-value ratio matters too. More equity means lower risk for the lender and a better rate. If your home has appreciated significantly, you may qualify for better terms than when you originally purchased. Our LTV Calculator shows where you stand.
Shop multiple lenders on the same day (rate quotes are time-sensitive). Credit inquiries for mortgage shopping within a 14-day window count as a single inquiry for credit scoring purposes. Get quotes from your current lender, a national online lender, and a local credit union for the best comparison.
