The Quick Read: The standard formula divides closing costs by monthly savings. On a cash-out loan, that formula usually fails, because the new loan is bigger and the payment often rises. The better test asks what the borrowed cash costs you and what it earns or replaces. Run it early with estimated costs, then confirm it against the Loan Estimate once you have applied and received it.
Why the Standard Formula Breaks on Cash-Out
The formula is closing costs divided by monthly savings. It gives you the number of months until the savings repay the costs. On a plain refinance, that works. The loan balance stays about the same, so a lower payment is the whole point.
Cash-out flips the setup. You borrow more than you owe, so the balance grows. The payment typically rises. If savings are zero or negative, the formula has nothing to divide by. Plenty of web guides skip this, and primary sources don’t help either. Fannie Mae and Freddie Mac don’t prescribe a break-even test for conventional cash-out loans. Treat the formula as a planning tool, not a rule.
| Factor | Rate-and-term | Cash-out |
|---|---|---|
| Loan balance | About the same | Larger |
| Monthly payment | Often falls | Usually rises |
| What you’re buying | A cheaper loan | Access to equity |
| Break-even test | Costs ÷ savings | Cost of cash vs. what it does |
The sequence that keeps a cash-out comparison honest is to decide the job of the cash first. The math follows from that.
What Is a Cash-Out Refinance, Exactly?
Freddie Mac defines a cash-out refinance as a mortgage with no specific restrictions on how you use the proceeds. For a primary residence, every borrower must occupy the home. You replace your current mortgage with a larger one and keep the difference.
Lendmire arranges cash-out refinance programs through wholesale lenders. Conventional cash-out generally tops out at 80% loan-to-value (LTV) on a one-unit principal residence. LTV is the loan balance divided by the home’s appraised value. On two- to four-unit homes, second homes and investment property, the cap drops to 75%. Occupancy decides the leverage, and that is all this article will say about rentals.
Seasoning applies too. Seasoning is the waiting period before you can refinance. The first mortgage being paid off must generally be at least 12 months old, and a borrower must have been on title for 6 months. Exceptions exist for delayed financing, inheritance and legal awards. Programs differ, and every figure here is subject to lender guidelines and full file review.
How Do You Run the Break-Even, Step by Step?
Gather these first: your current balance, current payment, remaining term, the proposed new loan amount, total closing costs and the cash you want. Then work through the steps.
1. Pull total closing costs from your Loan Estimate. The Loan Estimate is the form every lender must give you after you apply. Add the origination, services-you-cannot-shop-for, services-you-can-shop-for and government-fee sections. The CFPB notes you can shop for the services listed in section C of page 2.
2. Decide what the cash replaces. Paying off other debt, funding repairs and spending it freely are three different problems. Each has its own test.
3. Compare total monthly obligations. Don’t compare mortgage payments alone. Add the payments you retire, such as cards or an auto loan. Then subtract the increase in your mortgage payment. That net figure is your “true” monthly change.
4. Account for financed costs. Rolling closing costs into the loan raises the balance. That pushes break-even later and adds interest on the costs themselves.
5. Account for the term reset. A new 30-year clock lowers the payment but adds years of interest. A shorter term can raise the payment and still save interest.
6. Fix your holding period. How long will you realistically keep this loan? Include a possible sale or future refinance.
Then compare the months you need against the months you’ll hold.
The Cash-Out Test: Price the Cash, Then Ask What It Earns
Here is the replacement test. It has two halves.
Half one: price the cash. The cost of the cash is the extra interest on the added principal, plus any closing costs, plus the cost of re-pricing the balance you already had. That last piece matters. If your existing loan has favorable terms, replacing it carries a cost. If the terms are poor, replacing it can be a benefit.
Half two: price the return. Ask what the cash must save or add to justify that cost. Debt payoff saves the interest you stop paying. Renovation may add value or avoid a future expense. Spending has no payback at all.
Write it as a plain comparison:
Annual cost of the cash + annual share of closing costs, versus annual interest avoided or value added.
If the second side is bigger, the cash earns its keep. If not, the formula has told you something useful: look elsewhere.
Worked Example A: The Payment Rises
Say a homeowner takes a cash-out loan at 75% of the home’s value. Part of the cash retires two credit cards and an auto loan. The mortgage payment rises, so the savings-based formula has no positive number to use.
Run the net instead. The retired card and auto payments come off the monthly total. The mortgage increase goes on. If the retired payments are larger than the increase, the household’s monthly obligation falls, and you can divide closing costs by that net savings. Then add a harder question: are the cards likely to fill back up?
The CFPB’s research found that credit scores jumped after cash-out closings, then drifted back down. Scores stayed above where they started. Card balances trended up again without fully returning. Paying off cards with house equity only works if the cards stay paid.
Worked Example B: The Payment Falls
Now a homeowner with a high-cost existing loan takes a modest amount of cash at the same time. The new payment comes in below the old one. Here the familiar formula works: closing costs divided by monthly savings gives the months to break even.
Even here, read the result honestly. The added cash still carries interest. The longer term may stretch the payoff date. A short break-even doesn’t mean the loan is cheap overall. It only says the closing costs are earned back.
Break-Even by Use of Funds
| Use of cash | What to test | What breaks it |
|---|---|---|
| Pay off debt | Interest avoided vs. added mortgage interest | Running the balances up again |
| Home improvements | Value added or repair cost avoided | Spending that adds no value |
| Spending | Nothing earns back | Extra interest is a pure cost |
| Mixed use | Test each slice separately | Blending hides the weak piece |
If you split the cash, split the test. Debt payoff and renovation follow different logic. Many homeowners lump them together and then can’t tell which part paid off.
Does Your Holding Period Change the Answer?
Yes. The same loan can pass at one horizon and fail at another. Check break-even against three dates: the shortest you might stay, the most likely, and the longest.
- Break-even lands before your likely move: the costs are earned back.
- Break-even lands close to your move: the margin is thin. A small change in plans flips the result.
- Break-even lands well after your move: you are paying for a benefit you won’t collect.
Financing the costs shifts every line later. Build that into the test instead of discovering it at closing.
Where the General Rule Breaks: Named Edge Cases
Limited versus full cash-out. Fannie Mae treats these as two transaction types. A limited cash-out loan pays off only the first mortgage and any purchase-money second lien. Cash back is capped. Fannie Mae’s Announcement SEL-2025-08 set that cap at the greater of 1% of the new loan balance or $2,000. Older web guides still show a lower cap. Pay off a non-purchase second lien, and the loan becomes cash-out. That usually changes the leverage cap and pricing.
Streamlines are not cash-out. The FHA Streamline requires an existing FHA loan, a current payment history and a net tangible benefit. HUD limits cash back to $500. The VA IRRRL likewise offers no real cash-out. Neither can run a cash-out break-even.
FHA cash-out. HUD cut the maximum to 80% LTV in 2019, down from 85%. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
VA cash-out. Many summaries say VA stops at 90%. The 2018 final rule moved the ceiling to 100% of reasonable value and kept 90% as one of the net tangible benefit criteria. VA also requires lenders to give the veteran a written comparison of the old and new loans, which is a built-in break-even check.
Co-owner buyouts. Freddie Mac has a special-purpose cash-out category for buying out a co-owner, with a joint-ownership requirement.
Texas. Cash-out on a Texas homestead is capped by the state constitution, and the wholesale lane that reaches 89.99% LTV is not written there. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
The “No-Cost” Refinance Trap
A “no-closing-cost” refinance is not free. HUD notes that some of these loans work by charging a higher interest rate than you’d pay if you covered the costs. Others roll the costs into the balance. Either way, the cost is still there. It has moved into your monthly payment or your principal. Run the same break-even on it as you would on any other loan.
What Else Moves the Result?
- Amount of cash. More cash means more interest on the added principal.
- Mortgage insurance. Insurance is required above 80% LTV, cancels on request at 80% of original value and ends automatically at 78%. Conventional cash-out generally stays at or below 80%, so this matters most when comparing against a high-LTV alternative. One wholesale lane reaches 89.99% LTV with no mortgage insurance at a 680 score and a 50% ratio on a thirty-year fixed primary residence with a conforming balance. It carries its own six months of seasoning and is subject to lender guidelines.
- Pricing by loan type. Freddie Mac applies risk-based credit fees that differ for cash-out, no-cash-out and special-purpose loans. Cash-out loans are priced differently.
- Shopping the closing services. The CFPB says borrowers who shop for title services could save as much as $500 on those services alone.
When Break-Even Says No
A weak result isn’t a dead end. It points you to a different tool.
| If the test says | Consider | Trade-off |
|---|---|---|
| Cost of cash too high | A smaller cash-out amount | Less money in hand |
| Existing loan is favorable | Keeping it and borrowing separately | A second loan to manage |
| Break-even after your move | Waiting, or skipping it | Delays the use of the cash |
| Cash has no payback | Reconsidering the purpose | None, usually |
Every alternative has its own costs. Run the same comparison on each, using the same cash amount.
Common Mistakes
- Using the closing-costs-over-savings formula when the payment rose.
- Comparing only principal and interest and ignoring the retired debt payments.
- Forgetting that financed costs accrue interest.
- Ignoring the term reset and the extra years of interest.
- Treating a “no-cost” loan as free.
- Paying off cards, then running the balances back up.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.

Frequently Asked Questions
Is break-even just closing costs divided by monthly savings?
Only when the payment falls. On most cash-out loans, the payment rises, so the formula has no savings to use. Compare the cost of the cash against what it replaces or buys, then check the months against your holding period.
What is a good break-even period?
One that lands comfortably before you expect to sell or refinance again. No agency sets a standard for conventional cash-out. VA is the exception, because its rules require a written comparison and a net tangible benefit test on its cash-out loans.
What if I plan to move soon?
A short stay usually makes a cash-out loan harder to justify. The closing costs have less time to be earned back, and the extra interest on the larger balance still accrues. Test the shortest horizon you can imagine.
Do financed closing costs change the result?
Yes. Rolling them in raises the loan balance, adds interest on the costs and pushes break-even later. Compare the result both ways.
Does the Fannie Mae cash-back cap apply to a regular cash-out loan?
No. That cap applies to limited cash-out refinances. A full cash-out loan allows equity to be taken out for any purpose, within the LTV limit, subject to lender guidelines.
