Should You Refinance Your Mortgage in 2026?

Mortgage refinancing replaces your current loan with a new one — ideally at a lower interest rate, shorter term, or both. In 2026, millions of homeowners who bought or last refinanced when rates were above 7% are evaluating whether today's rates justify a refi. A refinance calculator takes the guesswork out of that decision by showing you exactly when you'll break even and how much you'll save over time.

The Break-Even Rule of Refinancing

The most important number in any refinance decision is the break-even month — the point at which your accumulated monthly savings equal your upfront closing costs. If you plan to stay in the home beyond that month, refinancing saves you money. If you plan to sell or move before then, the refi costs you money.

What Are Current Refinance Rates in 2026?

As of mid-2026, 30-year fixed refinance rates are averaging in the 6.25–6.75% range nationally, with 15-year fixed rates around 5.75–6.25%. Rates vary significantly by credit score, loan-to-value ratio, and lender. Borrowers with 760+ credit scores and 20%+ equity can often qualify for rates at the lower end of the range. Note that refinance rates typically run 0.10–0.20% higher than purchase rates due to added lender risk.

Types of Mortgage Refinances

Not all refinances work the same way. Understanding your options helps you pick the strategy that fits your goals:

Refinance Closing Costs: What to Expect

Refinancing isn't free. Typical closing costs run 2–5% of the loan amount. On a $400,000 refi, that's $8,000–$20,000 out of pocket. Key fees include:

Some lenders offer reduced-cost refis through loyalty programs or preferred customer pricing. Always get at least three quotes and compare the APR (not just the rate) to account for all fees.

Rate Drop Thresholds: How Much Lower Is Enough?

The old rule of thumb was "refinance if you can drop your rate by 1%." In reality, it depends on your loan balance, closing costs, and how long you'll stay. On a larger loan ($600,000+), even a 0.375% rate drop can justify refinancing quickly. On a smaller loan ($150,000), you might need a full 1–1.5% drop to break even in a reasonable timeframe. Our refinance calculator shows you the exact threshold for your specific loan.

Refinancing to Shorten Your Term

One of the most powerful — and often overlooked — refinance strategies is switching from a 30-year to a 15-year mortgage. You'll pay more per month, but dramatically less in total interest. A homeowner with a $350,000 balance at 7% on a 30-year loan pays roughly $487,000 in interest over the remaining life of the loan. Refinancing to a 6.0% 15-year loan means a higher payment (~$400/mo more) but saves roughly $300,000 in interest. That's generational wealth, not just monthly cash flow.

How Our Mortgage Refinance Calculator Works

Our calculator compares your current loan against a new refinance scenario using industry-standard amortization math. Enter your remaining loan balance, current interest rate, remaining term, new rate, new term, and estimated closing costs. The calculator instantly shows: new monthly payment, monthly savings, break-even month, total interest paid under both scenarios, and your cumulative savings timeline year by year.
