How Much Cash Can You Actually Take Out of Your House?
The ceiling is not a number you look up. It is home value times the lender's LTV cap, minus your balance and closing costs, and the formula leaves three real costs out.
Most people asking "how much can I take out" want a single number. The honest answer is a formula, and it takes about ninety seconds to run.
Cash available ≈ (home value × the loan-to-value ratio your lender allows) − what you still owe − closing costs.
Loan-to-value ratio — LTV, in lender shorthand — is the loan balance divided by the appraised value, expressed as a percentage. If your home appraises at $500,000 and you would owe $370,000 after the refinance, that is a 74% LTV. Most conventional lenders stop cash-out refinances near 80% LTV, which is where the ceiling in that formula comes from. Some programs allow more, some less; the only number that matters is the one your lender actually underwrites to, and you have to ask.
A worked example with real numbers
Say you bought at $395,000 three years ago with 20% down. Your balance is now $320,000 and the house appraises at $500,000.
At an 80% LTV cap, the largest loan the lender will write is $500,000 × 0.80 = $400,000. You owe $320,000, so the theoretical maximum cash is $80,000. That is the number before costs.
Now run it through an actual scenario — taking out $50,000 rather than the full $80,000:
- New loan: $320,000 + $50,000 = $370,000
- LTV: $370,000 ÷ $500,000 = 74%
- At 6.75% over 30 years, principal and interest comes to about $2,399.81 per month
- Cash received at closing: $50,000
That monthly figure is the part people fixate on, and it is the wrong thing to fixate on. Your old payment was presumably lower because your old balance was lower. You are not paying $2,399.81 for the same house — you are paying it for a house plus $50,000 in cash. The comparison that matters is your old payment versus your new payment, and the difference is the true price of that $50,000.
You can run your own numbers in the cash-out refinance calculator — it builds the new loan, checks the LTV, and shows the new principal-and-interest payment.
The rate you are refinancing into matters more than the cash
As of October 8, 2026, the average 30-year fixed rate was 7.40% (Freddie Mac Primary Mortgage Market Survey; the calculator shows the current weekly average). If your existing mortgage sits at 3.25% from 2021, a cash-out refinance today does not just add $50,000 of debt — it re-prices your entire $320,000 balance at more than double the rate.
Run that and the math gets ugly fast. The interest cost on the old balance alone can exceed the cost of the cash you took out. This is the single most common mistake in the category: people compare the cash-out rate against nothing, when the correct comparison is against the rate they already have.
If your current rate is below roughly 5%, a home equity line of credit — HELOC, a revolving second mortgage — often beats a full refinance, because it leaves the first mortgage untouched. The tradeoff is that HELOCs usually carry variable rates and a shorter repayment window. A 15-year versus 30-year comparison is also worth running if you are considering resetting the clock: shortening the term raises the payment but can dramatically cut total interest, which partially offsets the rate increase.
Three costs that do not show up in the calculator
Closing costs. A cash-out refinance is a new mortgage, not a modification. You pay for it again: appraisal, title, lender fees, recording. Ask every lender for the Loan Estimate — the federally required three-page form that breaks charges into a standardized format — and compare those side by side, not the advertised rate. A lender quoting 6.75% with $9,000 in fees is worse than one quoting 6.875% with $2,500.
The appraisal is not your Zestimate. The LTV is computed on the appraised value, not what your neighbor's house listed for or what a website estimates. If the appraisal comes in $30,000 below your expectation, your available cash drops by roughly $24,000 at an 80% cap. This is the most common reason a cash-out refinance shrinks between application and closing.
You are resetting the amortization clock. If you are seven years into a 30-year loan and you refinance into a new 30-year term, you have just extended your payoff date by seven years. The payment may drop; the total interest will not.
When it is genuinely a bad idea
- You plan to sell within two or three years. Closing costs need time to amortize against the monthly savings. Selling early means you paid the costs and never collected the benefit.
- You are using it to pay off consumer debt without changing the behavior that created it. Trading 22% credit card interest for 7% mortgage interest is arithmetically sound. It stops being sound the moment the card balance rebuilds, because now you have both. If this is the motivation, run the payoff plan first with a debt snowball calculator and see whether the consolidation actually changes your payoff date.
- Your emergency fund is thin. Converting home equity into cash to hold as cash costs you the mortgage rate every month you do not need it.
The one comparison people forget to run
Here is the scenario that produces the worst outcomes, and it is common right now.
You bought in 2021 at 3.25%. Your balance is $320,000 and your principal-and-interest payment is roughly $1,390 a month. You want $50,000 for a kitchen. At 6.75% — below the current market average, as a strong borrower would typically be quoted — refinancing into a $370,000 loan puts your payment near $2,400.
That is about $1,000 more every month, and only part of it is the $50,000. The larger share is your existing $320,000 being re-priced from 3.25% to roughly double that. Spread over thirty years, the interest cost of that re-pricing comfortably exceeds the $50,000 you walked away with.
This is not an argument against cash-out refinancing in general. It is an argument against evaluating it as "can I get $50,000" instead of "what does this do to the total cost of my housing." Run both loans side by side — old balance at old rate versus new balance at new rate — before you sign anything. If the gap makes you uncomfortable, a HELOC on a smaller amount, or simply waiting, usually looks better.
The tax question, briefly
Cash-out proceeds are not taxable income. You are borrowing against an asset, not earning money.
Whether the interest is deductible is a different question, and it depends on what you did with the money. Interest on proceeds used to buy, build, or substantially improve the home that secures the loan is generally treated as home acquisition debt. Interest on proceeds spent on other things — paying off cards, funding a business, buying a car — generally is not. The details live in IRS Publication 936, and the safe move is to ask a tax preparer before you assume the deduction.
Two more things worth asking about while you are comparing offers. First, whether the lender will let you bring cash to closing instead of rolling costs into the balance — financing your closing costs means paying interest on fees for thirty years, which is a quietly expensive default. Second, how long your rate lock lasts and what happens if the appraisal or title work pushes you past it. A 30-day lock on a file that takes 45 days is a real cost, not a footnote.
What to actually do next
Get three Loan Estimates, not three rate quotes. Put them side by side and look at one column: total cash you receive at closing, net of all costs. Then compare your new payment against your current payment and divide the difference into the net cash. That quotient is the real price of the money, and it is the only number worth comparing across lenders.
