Can I roll the closing costs into the loan?

Usually yes, if you have equity. It preserves cash but adds to the loan balance and slightly reduces monthly savings - factor both into the break-even calculation.

How often can I refinance?

There's no legal limit, but many lenders enforce a 'seasoning' period of six months on a new loan. More importantly, each refinance has its own break-even - doing it too often just resets the clock without capturing savings.

The Short Version

A refinance makes sense when the monthly savings pay back the cost of the refinance before you sell or refinance again. That's the whole test. Everything else - 'rates just dropped', 'my neighbor refinanced' - is noise.

The rule of thumb that a rate has to drop 1% to be worth it is outdated. Break-even is the real answer, and it depends on your closing costs, your monthly savings, and how long you'll stay.

The Break-Even Test in One Formula

Break-even in months = total closing costs of the new loan divided by the monthly payment savings. If you'll stay in the home past that many months, refinancing typically pays off. Anything before that, and you'd lose money on the transaction.

This is the same math whether the refinance drops your rate by 0.5% or 2%. It's the only calculation that matters for a rate-and-term refinance.

Break-Even Example on a $350,000 Loan

Current rate	7.25%
New rate (illustrative)	6.25%
Old P&I	≈ $2,388 / mo
New P&I	≈ $2,155 / mo
Monthly savings	$233
Closing costs on the refi	$5,600
Break-even	$5,600 ÷ $233 ≈ 24 months

If you'll keep the loan past month 24, the refi pays off. If you're likely to move or refinance again within two years, it doesn't.

Reasons Besides Rate That Can Justify a Refinance

Rate isn't the only trigger. The break-even framework still applies, but the savings side of the equation is broader:

Key points

Dropping FHA MIP by refinancing into a conventional loan once you have 20% equity.
Shortening the term (30 → 20 or 15) to save large amounts of lifetime interest.
Cashing out equity for a specific, high-value purpose - debt consolidation math is real and often ignored.
Removing a co-borrower after a divorce or partnership change.
Switching from an ARM to a fixed rate before the adjustment window.

Rate-and-Term vs. Cash-out vs. Streamline

There are three main refinance flavors, and the break-even test applies to all of them - but the inputs change.

Rate-and-term: refinance to a lower rate or different term. Uses the simple break-even formula.
Cash-out: rate typically 0.25%–0.5% higher than rate-and-term, and closing costs are higher - but pull out equity. Compare against your best alternative source of cash (HELOC, home equity loan, etc.).
Streamline: FHA and VA both have streamline programs (FHA Streamline, VA IRRRL) with reduced documentation, no appraisal in most cases, and lower fees. These have the fastest break-evens because the costs are so much lower.

How to Actually Run This

Ask your lender for a full Loan Estimate on the refi - not a verbal quote. The Loan Estimate lists total closing costs, so you can compute break-even in one line. If the lender resists giving you a full LE up front, ask a different lender.

Our refinance calculator will do the arithmetic for you once you have the two payments and the closing costs.

FAQ

Frequently Asked

No. The 1% rule is a shortcut that's often wrong. Break-even in months (closing costs ÷ monthly savings) is the real test. On a large loan balance, even a 0.375% drop can pay back within a couple of years.
