Cash-out refinancing: turning equity into cash
A cash-out refinance replaces your existing mortgage with a larger loan, and you take the difference home in cash. It's the primary way Americans access the equity in their homes — about $50 billion a quarter gets pulled out this way in a typical year. Done right, it can fund a major renovation, pay off high-interest debt, or seed a down payment on an investment property. Done wrong, it resets your mortgage clock, costs you thousands in closing fees, and converts flexible unsecured debt into secured debt that your home is collateral for.
This calculator gives you the three numbers that determine whether a cash-out refi makes sense: how much cash you'll actually net after closing costs, how much your monthly payment increases, and the true long-term cost of the cash (total interest you'll pay on the borrowed amount over the new 30-year term).
How the math works
Lenders cap cash-out refis at a maximum loan-to-value ratio. For conventional (Fannie/Freddie) loans, that cap is 80%. For FHA, 80%. For VA cash-out, up to 100% for eligible veterans. Jumbo lenders vary from 70% to 80%. Investment properties are usually capped at 70–75%.
The formula: maximum new loan = home value × max LTV. Subtract your existing loan balance and closing costs to get the cash you actually walk away with. On a $550,000 home with a $285,000 balance and 80% max LTV:
- Maximum new loan: $440,000
- Pay off existing: $285,000
- Closing costs (3%): $13,200
- Cash to pocket: $141,800
Closing costs typically run 2–5% of the new loan. Origination fees, appraisal ($500–$800), title insurance, recording fees, prepaid escrow, and sometimes discount points. On a $440k loan at 3%, that's $13,200 in fees — a meaningful haircut to the cash number you're targeting.
When cash-out refi makes sense
You have high-interest debt to consolidate.Credit card balances at 22% APR are brutal. Paying them off with a 6.5% mortgage cuts your interest cost by 70%. BUT — you have to have the discipline not to re-run the cards. The most common cash-out refi horror story is "I paid off my $40k credit card with a cash-out refi, then ran up the cards again, and now I have $80k of debt plus a bigger mortgage."
You're funding a renovation that adds value. If you can borrow at 6.5% to add a kitchen or second bathroom that increases the home's value by more than the cost of the renovation, the spread is free money plus the interest is tax-deductible. Run the cost-vs-value math in our renovation ROI calculator first.
You're buying an investment property. Using cash-out to seed a down payment on a rental is a classic real estate investor move. Your borrowed cash earns whatever the rental cash flow plus appreciation produces; your cost is the new mortgage rate. If the rental returns 9% and your rate is 6.5%, the 2.5% spread compounds over the hold period. See our BRRRR strategy calculator for the full investor version of this play.
When cash-out refi is a mistake
Your existing rate is much lower than current rates. If you locked a 3% mortgage in 2021 and cash-out refi rates today are 7%, you're paying 4% more on your entire balance just to access some equity. The effective cost of the cash is enormous. Use a HELOC instead — it keeps your first mortgage at the low rate and only charges you rate on what you draw.
You're buying depreciating assets.A car, a boat, a wedding, a vacation. These lose value while your mortgage compounds. Over 30 years, $40,000 of cash-out at 6.5% costs you about $90,000 in total interest. That's a very expensive way to finance something that's worth zero in ten years.
You're nearly at loan payoff.If you're 23 years into a 30-year loan, you have 7 years left of mostly-principal payments. A cash-out refi restarts the 30-year clock. You add another 23 years of total interest just to access some equity. Usually not worth it.
Texas has its own rules
Texas is the one state with constitutional protections on home equity lending that add unusual constraints to cash-out refinances. Notable rules: max 80% LTV (state constitutional limit, not just lender policy); 3% cap on total fees; 12-day mandatory waiting period after loan application; cannot refinance within 12 months of a previous cash-out. If you're in Texas, verify your lender documents comply with Section 50(a)(6) of the Texas Constitution.
Cash-out refi vs. HELOC vs. home equity loan
Cash-out refi. Replaces your first mortgage. Fixed rate (usually), fixed monthly payment, all cash at closing. Best for large one-time needs with a long payback horizon. Costs 2–5% of loan in closing fees.
HELOC. Second mortgage, line-of-credit structure. Variable rate (tied to prime). Interest-only during 10-year draw period. Only pay interest on what you draw. Best for uncertain or staged needs. $0–$500 in fees typically. See our HELOC calculator.
Home equity loan.Second mortgage, lump sum, fixed rate. Similar to cash-out refi but keeps your first mortgage untouched. Higher rate than first-lien but cheaper closing ($500–$2,500). Best when your first mortgage rate is much lower than current rates and you don't want to refinance it.
The true cost of the cash you pull out
This is the number most homeowners underestimate. When you pull $150,000 out of your home over a 30-year term at 6.5%, the total interest on that $150k portion is roughly $192,000. You're paying $192,000 to access $150,000 of cash. That's 1.28× the cash you received, and it's only the interest — principal is the $150k itself, so you're actually paying back $342,000 over 30 years.
Is that bad? It depends on what you do with the cash. If you invest at 10% and it grows to $2.6M over 30 years, the $192k of interest is trivial. If you spend it on a wedding, you've permanently destroyed $192k of future wealth for one day of celebration. The calculator above shows the total interest on the cash portion so you can weigh it against the return you'll get from deploying the money.
Timing: rates matter enormously
Cash-out refi rates are usually 0.25–0.50% higher than a standard rate-and-term refi. If you're already refinancing to lower your rate, adding cash-out is cheap. If your current rate is already lower than market, the penalty for doing cash-out instead of sitting still is substantial.
Run the numbers both ways. Compare the cash-out refi to a separate HELOC stacked on your existing low-rate first mortgage. The HELOC at a higher rate on a smaller balance often beats a cash-out refi at a lower rate on a bigger balance.
