HELOC vs Cash-Out Refinance: which is right for you?
Both let you access your home equity. The right choice depends mostly on one number — your current first mortgage rate. If it's lower than today's rates, a HELOC almost always wins. If it's higher, cash-out refinance can deliver a bigger number at a lower blended cost.
| Feature | HELOC | Cash-Out Refi |
|---|---|---|
| Effect on existing mortgage | Untouched — keeps your low rate | Replaces existing mortgage with new one |
| Disbursement | Draw as needed during 10-yr period | Lump sum at closing |
| Rate type | Variable (prime + margin) | Fixed for the new loan term |
| Typical APR (2025) | 8.0–9.5% | 6.5–7.5% on the new first mortgage |
| Closing costs | $0–$500 (often waived) | 2–5% of loan amount ($6K–$25K typical) |
| Repayment structure | Interest-only during draw, then amortizing | Amortizing from day one — full P&I |
| Max loan amount | Up to 80–90% CLTV; typical cap $250K–$500K | Up to conventional limits ($806K baseline) |
| Time to close | 2–4 weeks typically | 30–45 days typically |
| Tax deductibility | Interest deductible if used for home improvements | Interest deductible up to $750K of total debt |
| Best for | Smaller amounts, ongoing access, low first-mortgage rate | Large amounts AND existing rate is high |
The most important rule
If your current first mortgage rate is lower than current market rates, do NOT cash-out refinance. You'll lose your low rate on the entire balance — not just the cash-out portion.
Most US homeowners who bought between 2020 and 2022 are sitting on mortgages at 2.5–3.5%. With current rates around 6.5–7%, refinancing to extract $50K of equity would mean re-pricing the whole $300K balance at the higher rate. The interest cost on the existing balance alone would dwarf any savings on the cash-out portion.
In that case: HELOC wins automatically, even at a higher headline APR.
When a HELOC wins
- Your first mortgage rate is below current market. You don't want to refinance the whole balance at today's higher rate.
- You need flexibility. Draw as you go for ongoing renovations, or open a line you may never use as an emergency fund.
- You want low closing costs. $0–$500 typical vs $6K–$25K for refi.
- You want to close fast. 2–4 weeks vs 30–45 days.
- You expect to pay it off quickly. Variable rate risk shrinks if you only carry the balance for 1–3 years.
When cash-out refinance wins
- Your existing rate is higher than current market. You get a rate reduction on the entire balance + the cash-out amount as a bonus.
- You need a large amount ($150K+). HELOC pricing gets ugly at high balances. A 6.5% cash-out refi on $200K extra beats a 9% HELOC on the same balance over time.
- You want a fixed payment. Variable HELOC rate is uncomfortable on a long-held balance.
- You're consolidating other high-rate debt. Rolling credit cards (22% APR) or personal loans (12% APR) into a 6.5% mortgage can save hundreds per month — if your existing rate isn't already lower.
The math: $50K cash on a $300K mortgage at 3% (locked in 2021)
Say you bought in 2021 with a $300K mortgage at 3%, current balance $280K, and you want $50K cash for a renovation. Current market rates are 6.5%.
- Cash-out refi @ 6.5% for 30 years on $330K total: ~$2,090/mo. Total interest over 30 years ≈ $422K. (Vs your existing ~$1,180/mo — a payment increase of $910/mo.)
- HELOC @ 9% on $50K, 10-year amortizing repayment after draw: ~$50/mo interest-only during draw, ~$635/mo amortizing. Existing $1,180/mo mortgage continues unchanged. Total monthly ~$1,815. Total HELOC interest ≈ $26K.
HELOC saves ~$396K over 30 years in this scenario, entirely because you don't lose your 3% rate on the existing balance.
The math: $50K cash on a $300K mortgage at 7.5% (took out in 2024)
Same $50K need, but your existing rate is already higher than current market.
- Cash-out refi @ 6.5% on $330K: ~$2,090/mo. Saves you ~$60/mo on the existing portion (re-priced from 7.5% to 6.5%) and gives you the $50K. Net good deal.
- HELOC @ 9% on $50K: ~$50/mo interest-only, existing $2,030/mo at 7.5% continues. Combined ~$2,080/mo during draw — basically a wash on payment, but you're paying 9% on $50K instead of 6.5% on $50K.
Cash-out refi wins by capturing the rate reduction on $280K balance. HELOC only makes sense if you'll pay it off fast.

Quick decision tree
- Existing rate < current market rate? → HELOC
- Existing rate > current market AND need $150K+? → Cash-out refinance
- Need flexibility, ongoing access? → HELOC
- Need lump sum, want fixed payment, existing rate is high? → Cash-out refinance
- Want low closing costs and fast close? → HELOC
