Mortgage Refinance Savings Calculator — Is Refinancing Worth It in 2026?

Should You Refinance Your Mortgage in 2026? This Free Calculator Shows Exactly How Much You'd Save

With mortgage rates hovering around 6.5–7% after the Federal Reserve held the federal funds rate at 4.25–4.50% through March 2026, millions of homeowners are asking: is refinancing worth it right now?

The answer depends on three numbers: your current rate, your new rate, and your closing costs. Our Mortgage Refinance Savings Calculator does the math instantly.

What the Calculator Shows You

Enter your current loan balance, interest rate, remaining term, and the new rate you've been quoted. The calculator returns:

  • Monthly payment reduction — the immediate cash flow improvement
  • Break-even month — when cumulative savings exceed closing costs
  • Total interest saved — often $20,000–$80,000 over the loan life
  • Side-by-side cost comparison — remaining current loan vs. new loan with closing costs

When Refinancing Makes Sense

The classic rule: refinance when you can drop your rate by at least 0.75–1.0 percentage points AND plan to stay in the home past the break-even point. With typical closing costs of 2–5% of the loan amount (source: CFPB), a $300,000 refi at $9,000 in costs needs roughly 18–24 months to break even on a 1% rate drop.

The 2026 Rate Environment

The OBBB Act (P.L. 119-21, signed July 4, 2025) stabilized the tax landscape, but mortgage rates remain elevated versus the 2021 lows. Homeowners who locked in 2.5–3.5% rates during 2020–2021 likely shouldn't refinance. But those with 7.5%+ rates from 2023 purchases may find significant savings as rates moderate.
