What Is a Cash-Out Refinance?
A cash-out refinanceis a mortgage transaction in which you replace your existing home loan with a new, larger loan and receive the difference as a lump sum at closing. The cash you receive is drawn from your accumulated home equity, the difference between your home's current market value and what you still owe on the mortgage. Unlike a regular rate-and-term refinance that simply restructures your existing debt, a cash-out refinance taps into the value your home has gained, converting illiquid equity into usable cash. This cash-out refinance calculator models the entire transaction so you can see exactly what the deal looks like before you apply with a lender.
Lenders typically cap cash-out refinances at 80% of your home's appraised value (the loan-to-value or LTV limit), though VA cash-out loans can reach 100% for eligible veterans and FHA cash-out loans cap at 80%. To find your maximum cash, multiply your home value by 0.80 and subtract your current mortgage balance, the remainder, minus closing costs, is the most cash you can take out. The cash-out refi calculator on this page applies the standard 80% cap automatically and will warn you if your requested cash exceeds the limit. For a deeper look at your equity position, our home equity calculator shows your current equity, LTV ratio, and borrowing capacity in detail.
The new loan carries a new interest rate, a new term, and new closing costs (typically 2% to 5% of the loan amount), and it fully replaces your old mortgage. Your old monthly payment goes away, replaced by a new monthly payment based on the larger principal. According to the Consumer Financial Protection Bureau guide to cash-out refinancing, the most important question to answer before doing one is whether the cost of replacing your low-rate mortgage with a higher-rate larger loan is justified by what you do with the cash.
Cash-Out Refi vs HELOC vs Home Equity Loan
All three products let you access home equity, but they behave very differently. A cash-out refinance replaces your existing mortgage entirely with a new, larger, single fixed-rate loan. A home equity loan is a separate fixed-rate second mortgage taken on top of your existing first mortgage; you receive a lump sum and repay it over its own term, typically 5 to 30 years. A HELOC (home equity line of credit) is a revolving, variable-rate credit line secured by your home that you can draw on and repay multiple times during the draw period, then amortize during the repayment period. The cash-out refinance loan calculator above lets you input HELOC and home equity loan rates so you can see all three options side-by-side.
The most important variable in this choice is your current mortgage rate relative to today's market rates. If your existing mortgage is at 3% and today's rates are 7%, doing a cash-out refinance forces you to give up that ultra-low rate on your entire balance just to access equity, almost always a losing trade. In that scenario a HELOC or home equity loan, which preserves your low-rate first mortgage, is dramatically cheaper. Use our HELOC calculator to model the variable-rate draw and repayment phases, and compare against the cash-out refinance output above. If rates have dropped since you took out your mortgage, the cash-out refi usually wins because you reduce your blended rate and pull cash in one transaction.
Closing costs also differ significantly. A cash-out refinance carries full mortgage closing costs of 2% to 5% of the loan, a home equity loan typically runs $500 to $2,000, and many lenders waive HELOC closing costs entirely. For a $50,000 cash need, the closing-cost difference alone can be $5,000 to $15,000 in favor of the HELOC or home equity loan. The trade-off is the variable rate on a HELOC and the dual-payment burden of a second mortgage. Run all three scenarios in the cash-out refinance calculator to see how they compare for your specific numbers.
When a Cash-Out Refinance Makes Sense
A cash-out refinance makes the most sense in four specific situations. First, when current mortgage rates are at or below your existing rate, replacing your loan does not increase your blended cost. Second, when you need a substantial sum (typically $50,000 or more) where the closing-cost efficiency of rolling everything into one mortgage beats stacking a smaller home equity loan. Third, when you have a clear, high-value use for the cash such as home improvements that increase property value, paying off double-digit-rate credit card balances, or funding tuition that would otherwise carry higher private-loan rates. Fourth, when you want to refinance anyway for rate or term reasons and the cash-out is incremental.
Home improvements are the most defensible use because they can increase the property's value, partially or fully offsetting the larger loan balance. Debt consolidation is a close second when the math is clear, replacing a $30,000 credit card balance at 22% APR with mortgage debt at 6.5% saves thousands per year, but only if you keep the cards paid off afterward. The Freddie Mac research on cash-out refinancing shows that homeowners use cash-out funds for debt consolidation, home improvements, and investment in roughly equal measure, but financial outcomes diverge sharply by use case.
A cash-out refinance is generally not appropriate for funding lifestyle spending (vacations, weddings, new cars), for speculation in markets, or as a recurring strategy. You are converting your home, typically your largest asset, into a tap for short-term needs while extending the timeline to outright ownership. Before pulling cash out, also model a standard refinance using our refinance calculator to compare against rate-and-term-only options that do not touch your equity.
Tax Implications of a Cash-Out Refinance
The Tax Cuts and Jobs Act of 2017 made the tax treatment of cash-out refinances more restrictive. Under current law, interest on the cash-out portion of a refinance is only tax-deductible if the funds are used to buy, build, or substantially improve the home that secures the loan. This means cash used for home renovations such as a kitchen remodel, addition, or new roof generates deductible interest on the new mortgage debt. Cash used to pay off credit cards, buy a car, take a vacation, or fund tuition does not qualify for the home mortgage interest deduction, even though it is technically secured by your home.
The total mortgage debt eligible for the interest deduction is capped at $750,000 for loans originated after December 15, 2017 (or $1 million for loans originated before that date). If your cash-out refinance pushes your balance above that limit, only the interest on the qualifying portion is deductible. The standard deduction was also raised significantly in 2017, so many homeowners no longer itemize, meaning the mortgage interest deduction provides no benefit unless your total itemized deductions exceed the standard amount. The Investopedia cash-out refinance overview covers the tax mechanics in detail; consult a CPA for your specific situation because this cash-out refinance calculator does not factor in tax effects.
Closing costs themselves are generally not tax-deductible in the year of the refinance, but certain costs (such as discount points) may be amortized over the life of the new loan. The cash you receive from a cash-out refinance is not taxable income because it is borrowed money, not earnings. If you use the cash to invest in another property and that property generates rental income, the interest may be deductible as an investment expense or rental expense depending on how the funds are traced. Talk to a tax professional before relying on any of these treatments. IRS rules on debt tracing are detailed and often misunderstood.
Qualifying for a Cash-Out Refinance
Qualifying for a cash out mortgage calculator result that matches a real lender approval requires meeting several underwriting thresholds. Most conventional cash-out refinance programs require a minimum credit score of 620, with the best rates reserved for borrowers with scores above 740. Your debt-to-income (DTI) ratio, total monthly debt payments divided by gross monthly income, must generally stay at or below 45%, with some programs allowing up to 50% for borrowers with compensating factors. You will need at least 20% equity remaining after the cash-out (the standard 80% LTV cap), and lenders typically require you to have owned the home for at least 6 to 12 months before allowing a cash-out refinance.
Documentation requirements are similar to those for an original mortgage: two years of W-2s or tax returns, the last 30 days of pay stubs, two months of bank and asset statements, identification, and authorization for a credit check. Self-employed borrowers face additional scrutiny and typically need two full years of tax returns showing consistent or growing income. A new appraisal is required to establish current home value. This is what the lender uses to compute LTV, and if the appraisal comes in lower than expected, your cash-out amount shrinks. Use our loan-to-value calculator to see how a lower appraisal would affect your borrowing capacity.
Special programs offer more flexibility. FHA cash-out refinances accept credit scores as low as 580, though they still cap LTV at 80% and require mortgage insurance premiums for the life of the loan. VA cash-out refinances for eligible veterans permit borrowing up to 100% of home equity and waive mortgage insurance, but include a one-time VA funding fee. USDA rural housing loans do not currently offer a cash-out option. Always request a Loan Estimate from at least three lenders, the cash-out refinance calculator above lets you plug in each lender's rate-and-fee combination to see the true total cost of each offer.
