A cash-out refinance replaces your mortgage with a larger one and pays you the difference in cash. People use it for renovations, to consolidate high-interest debt, or to cover large expenses. The key questions are how much you can actually get, and what it really costs once your whole balance moves to a new rate.
How much can you borrow?
Lenders cap cash-out loans at a maximum loan-to-value (LTV) ratio:
- Conventional: typically up to 80% of the home’s value for a primary residence.
- FHA: up to 80%, with occupancy and payment history requirements.
- VA: can allow higher LTVs for eligible borrowers; many lenders cap it around 90%.
Maximum cash ≈ (home value × max LTV) − current balance − closing costs.
Worked example
Your home is worth $450,000. Five years ago you took a $300,000, 30-year loan at 3.5%. Your payment is $1,347.13 and your balance is $269,091.22.
- 80% of $450,000 = $360,000 maximum new loan.
- $360,000 − $269,091 = $90,909 before costs.
- Closing costs of about 3% of the new loan ($10,800) leave roughly $80,109 in cash.
The catch is the payment. At an example rate of 6.75%, a new $360,000, 30-year loan costs $2,334.95 per month, which is $987.82 more than today. Even a smaller $50,000 cash-out would raise the loan to about $319,091 and the payment to $2,069.62, an increase of $722.49 a month, because your entire balance moves from 3.5% to 6.75%.
When cash-out refinancing makes sense
- Current rates are similar to or lower than your existing rate, so you are not giving up a cheap loan.
- You are replacing much higher-interest debt and will not run that debt back up.
- You need a large sum and prefer one fixed payment.
- The money funds improvements that add value or are necessary repairs.
When to look at alternatives
If your current mortgage has a low rate, a home equity loan or HELOC lets you borrow only what you need while keeping your first mortgage untouched. In the example above, a $50,000 HELOC at an example rate of 8.5% interest-only would add $354.17 a month, far less than the $722.49 increase from a cash-out refinance, though HELOC rates are usually variable.

Risks to understand
- Your home is the collateral. Turning unsecured debt like credit cards into mortgage debt means missed payments can put your home at risk.
- Restarting the clock. A new 30-year loan adds years of payments; see how to refinance your mortgage.
- Less equity if home values fall or you need to sell soon.
- Closing costs on the whole new loan, not just the cash portion. See closing costs explained.

Frequently asked questions
How much cash can I get from a cash-out refinance?
Most conventional and FHA cash-out refinances let you borrow up to 80% of your home’s current value. Subtract your current balance and closing costs to estimate the cash you would receive. VA cash-out loans can allow more, depending on the lender.
Is a cash-out refinance a good idea?
It can be if the new rate is close to or lower than your current rate, or if you are replacing much more expensive debt. It is usually expensive if it replaces a low-rate mortgage, because the new rate applies to your entire balance.
Is cash from a refinance taxable?
Cash-out proceeds are loan money, not income, so they are generally not taxed. Whether the interest is deductible depends on how you use the money and IRS rules; check with a tax professional.
What is the alternative to a cash-out refinance?
A home equity loan or a HELOC lets you borrow against your equity while keeping your first mortgage and its rate. Compare them in our HELOC vs. cash-out refinance guide.
