This payment comparison tool models monthly payments for both a HELOC and a cash-out refinance over time. It accounts for variable-rate HELOC adjustments versus fixed-rate refinance stability, helping you understand how each option affects your monthly budget.
When you need to tap home equity — for renovations, debt consolidation, college tuition, or other major expenses — two main options exist: a Home Equity Line of Credit (HELOC) and a cash-out refinance. They access the same equity but work very differently. A HELOC is a second lien with a revolving credit line, while a cash-out refi replaces your entire first mortgage with a larger one. The right choice depends on your current mortgage rate, how much you need, and whether you prefer fixed or variable payments. This calculator compares both options side by side so you can see the true cost difference. For broader mortgage decisions, also see our Mortgage Calculator and Refinance Calculator.
HELOCs shine when you have a low existing mortgage rate that you don't want to lose. If you locked in at 3% and current rates are 7%, refinancing would cost you thousands per year in additional interest on your existing balance — far more than the HELOC interest on the smaller amount you need. HELOCs also have minimal closing costs ($0–$750 vs. 2–5% for a refi), make sense for smaller amounts ($10,000–$50,000), and allow you to draw funds as needed rather than taking a lump sum. The downside: HELOC rates are typically variable, meaning payments can increase if rates rise. Some lenders offer fixed-rate HELOC options at a slightly higher rate.

A cash-out refi makes sense when current rates are similar to or lower than your existing rate — you're essentially getting "free" access to equity by refinancing at the same or better rate. It also works well for large amounts ($75,000+) since you get one combined payment at a fixed rate, eliminating the variable-rate risk of a HELOC. If you're consolidating high-interest debt, the fixed rate provides predictable payments. The main costs are closing costs (2–5% of the new loan amount, which includes both the refinanced balance and the cash-out portion) and potentially extending your loan term.

In a low-rate environment, cash-out refinancing is usually the winner because you can lock in a low fixed rate on the entire loan. In a high-rate environment (like the mid-2020s), HELOCs often win because keeping a low existing mortgage rate is extremely valuable. The math is straightforward: if your current mortgage is at 3.25% and refi rates are 6.75%, you'd pay 3.5% more on your entire $280,000 balance ($9,800/year) just to access $60,000 — that's effectively a 16.3% cost on the cash-out portion. A HELOC at 8.5% on just the $60,000 costs $5,100/year — significantly less. Run different rate scenarios through our Interest Rate Calculator.
| Factor | HELOC | Cash-Out Refi |
|---|---|---|
| Upfront costs | $200–$1,500 | $4,000–$8,000 |
| Interest rate (2026) | 8–10% variable | 6.5–7.5% fixed |
| Monthly payment ($50K) | $333–$417 (interest only) | Included in new mortgage |
| 5-year interest cost | $20,000–$25,000 | $16,250–$18,750 |
Beyond the basic comparison, several real-world scenarios dramatically change which option delivers better financial outcomes. Understanding these nuances helps you avoid the common mistake of making a decision based solely on current monthly payment comparisons.
Using home equity to consolidate high-interest debt (credit cards at 18–25%, personal loans at 10–15%) into a lower-rate HELOC or refinance can save thousands in interest annually. However, this strategy converts unsecured debt into secured debt — a critical distinction. If you default on credit cards, creditors can sue and potentially garnish wages, but you keep your home. If you default on a HELOC or mortgage, you risk foreclosure. The consolidation only makes financial sense if you simultaneously address the spending patterns that created the high-interest debt. Otherwise, many borrowers find themselves with a maxed HELOC and new credit card balances within 2–3 years — a far worse position than they started in.
For renovation financing, HELOCs are often superior because renovation spending is inherently phased. You might spend $15,000 on demolition and framing in month one, nothing in month two while waiting for inspections, then $20,000 on finishes in month three. A HELOC lets you draw only what you need when you need it, paying interest on $15,000 for the first month rather than on the full $50,000 from day one. This phased interest savings typically amounts to $500–$2,000 over a six-month renovation compared to having the full cash-out amount sitting in a checking account earning minimal interest while your mortgage accrues on the full balance.
Real estate investors frequently tap home equity for down payments on investment properties. A HELOC provides maximum flexibility — draw the down payment, close on the property, then repay the HELOC from rental income. The HELOC interest is potentially deductible as investment interest expense (consult a tax advisor for your situation). A cash-out refinance provides a fixed, predictable cost structure for this same strategy but locks you into the higher payment regardless of whether you deploy the capital immediately. If you are actively searching for deals but have not found one yet, a HELOC lets you hold the line of credit without paying interest on unused funds.
This is often the deciding factor. If your existing mortgage rate is below current market rates (common for anyone who locked in during 2020–2021), a cash-out refinance forces you to reprice your entire balance at the higher rate. On a $300,000 balance, moving from 3% to 7% adds roughly $800/month to your payment — dwarfing any benefit from the cash-out amount. A HELOC preserves that low first mortgage entirely. Conversely, if your existing rate is at or above current rates, a cash-out refinance lets you lower your rate on the existing balance while accessing equity — a dual benefit the HELOC cannot match.
From a pure wealth-building standpoint, the fastest path to financial freedom involves minimizing the total interest paid across your lifetime. Run both scenarios through a full amortization schedule including the HELOC repayment period. In many cases, a shorter-term refinance (15-year instead of 30-year cash-out) combined with aggressively paying down the balance outperforms a HELOC that lingers near its maximum for years. However, cash flow flexibility matters — a strategy that looks optimal on a spreadsheet but strains your monthly budget to the point of creating financial stress is not truly optimal.

→ The HELOC interest-only phase masks the true cost. During the draw period, you might pay $400/month on a $100,000 HELOC. When repayment begins, that jumps to $900–$1,200/month. Make principal payments during the draw period if possible to avoid payment shock later.
→ Your debt-to-income ratio affects qualification for both. Lenders typically require a DTI below 43% for cash-out refinances and below 50% for HELOCs. If you're close to the limit, the lower initial payment of a HELOC may help you qualify. Use our Debt-to-Income Calculator to check.
→ Tax deductibility depends on how you use the funds. Interest on home equity borrowing is only deductible if the funds are used to "buy, build, or substantially improve" the home securing the loan. Using HELOC funds for debt consolidation, tuition, or other purposes means the interest is not deductible under current tax law.
→ Consider a hybrid approach: keep your mortgage and open a smaller HELOC. You don't have to choose one or the other exclusively. Some borrowers keep their low-rate first mortgage, open a HELOC for flexibility, and only draw what they need. This minimizes interest cost while preserving access to equity. See our Mortgage Calculator for refinance modeling.

The Tax Cuts and Jobs Act of 2017 changed how homeowners deduct interest on home equity borrowing. Under current rules, interest on a HELOC or cash-out refinance is only deductible if the funds are used to buy, build, or substantially improve the home securing the loan. Using a HELOC to consolidate credit card debt, pay tuition, or fund a vacation means the interest is not deductible — even though the loan is secured by your home. This is a significant departure from pre-2018 rules that allowed deduction regardless of how funds were used.
Cash-out refinance interest generally remains fully deductible because the entire loan is classified as acquisition debt, up to the $750,000 mortgage interest deduction cap for loans originated after December 15, 2017. However, if you refinance into a larger loan and use the excess cash for non-home purposes, only the portion used for home improvements qualifies. Keep detailed records of how you spend the funds in case of an audit. Consult a tax professional before choosing between these options, as the tax savings on deductible interest can significantly shift the effective cost comparison between a HELOC and a cash-out refinance.
