HELOC vs Cash Out Refinance Calculator

Enter your home value, current mortgage balance, and the cash you need. The HELOC vs cash out refinance calculator compares a HELOC against a cash out refinance so you can see the monthly payment and the cost of each route before you choose.

The HELOC or cash out refi decision usually comes down to one question. A cash out refinance replaces your existing mortgage, so the new rate applies to the whole balance. A HELOC sits behind it and leaves that first mortgage untouched.

A cash out refinance pays off your current loan and replaces it with a larger one. You receive the difference as a lump sum at closing, and you have a single mortgage payment afterwards.

A HELOC is a revolving line of credit secured as a second lien. Your first mortgage stays exactly as it is. You draw what you need, when you need it, and you pay interest only on the balance you have drawn.

The first vs second lien distinction drives everything else: pricing, closing costs, payment structure, and how much flexibility you keep.

The rate impact on existing mortgage debt is one of the biggest factors in the decision.

If your current mortgage carries a rate well below today's market, a cash out refinance replaces that rate across your entire balance, not just the cash you are taking. Borrowing $60,000 can therefore reprice $300,000 of debt you were perfectly happy with.

A HELOC avoids that. The first mortgage keeps its rate and term, and the new borrowing amount is priced separately.

When the gap between your existing rate and current market rates is wide, this helps you decide the best choice for you.

The draw period vs. lump sum difference affects both cost and discipline.

A cash out refinance gives you the entire amount at closing, and interest starts on all of it immediately. That suits a single large expense with a known cost.

A HELOC has a draw period, commonly around ten years, during which you borrow as needed and typically make interest-only or low payments on the drawn balance. A repayment period follows, often around twenty years, when the line closes to new draws and you repay principal and interest.

For staged projects, where costs arrive over months, paying interest only on what you have used can save a meaningful amount.

HELOCs are usually variable, tied to the prime rate, so your payment moves when rates move. Some lenders allow you to lock a fixed rate on a portion of the balance, which limits that exposure.

A cash out refinance can be fixed for the full term, which gives certainty. That variable vs fixed rate choice matters most if your budget has little room to absorb a payment increase, and if you expect the balance to stay outstanding for years rather than months.

HELOCs generally have lower upfront closing costs than refinancing. A refinance carries the full set of mortgage costs, commonly ranging from 2% to 5% of the loan amount, including lender fees, title work, and the appraisal.

HELOCs frequently come with low or no closing costs, though you should check for annual fees, early closure fees if you repay within a set period, and any appraisal requirement. The headline cost and the total cost are not always the same, so compare both over the period you expect to carry the balance.

Figures are typical market standards rather than guarantees. Terms, leverage limits, and fees vary by lender.

Both routes are limited by your equity. Lenders set a maximum combined loan-to-value across all liens on the property, commonly around 80% for a cash out refinance and sometimes higher on a HELOC, subject to credit and program.

A home equity comparison needs real numbers, so here is a worked example. On a $500,000 home with a $300,000 mortgage, an 80% limit allows $400,000 of total debt, leaving roughly $100,000 of accessible equity before costs. Your credit score, income documentation, and occupancy all affect where your actual limit lands.

Tax deductibility of interest on either route depends on how you use the money. Under current federal rules, interest on home equity borrowing is generally deductible only when the funds are used to buy, build, or substantially improve the home securing the loan, and overall limits apply.

Using the money for other purposes, such as consolidating consumer debt or paying tuition, usually removes that treatment. Rules change and individual situations differ, so confirm the position with your tax advisor rather than planning around a general statement.

The HELOC vs cash out refinance choice is rarely close once you look at the numbers. Choose a cash out refinance when your existing rate is at or above market, you want one payment, and you need the full amount at once. Choose a HELOC when your first mortgage carries a rate worth protecting, your spending is staged, or you want a facility available without drawing it immediately.
