When Does Refinancing Your Mortgage Make Sense?
Updated 2026-06-03 · FinCalc Hub Editorial
Refinancing can save real money — or cost you, if you don't stay long enough to recover the fees. Here's how to tell the difference.
Start with the break-even point
Refinancing has closing costs, often 2–5% of the loan. Divide those costs by your monthly savings to get the break-even point in months.
If you'll stay in the home past break-even, refinancing likely pays off. If you might sell sooner, it probably won't. The refinance calculator does this math for you.
How big a rate drop do you need?
There's no magic number, but a drop of 0.5–1% or more usually makes the savings worth the effort, especially on a large balance.
Even a smaller drop can be worthwhile if closing costs are low or you're shortening your term.
Watch the term reset
Refinancing into a new 30-year loan lowers the payment but can extend how long you're paying. Compare lifetime interest, not just the monthly payment, before deciding.
