Cash-Out Refi vs HELOC in 2026: The Break-Even Math Most Articles Skip
Most cash-out vs HELOC explainers stop at "HELOCs are flexible." The actual answer depends on your LTV, your existing rate, and how long you'll hold the debt. We do the math.
What we liked
- ✓HELOC wins under three years — If you'll repay within 36 months, the HELOC's lower closing costs and prime-pegged rate usually beat a cash-out refi even at higher headline rates.
- ✓Cash-out refi wins on long horizons — If the cash supports a 7+ year project (renovation, debt consolidation, college funding), the fixed cash-out rate locks in certainty that floating HELOCs can't.
- ✓Hybrid strategies are real — Doing a small rate-and-term refi alongside a smaller HELOC sometimes beats either pure approach. We've seen it work for borrowers north of 70% LTV.
What could be better
- !"Just take the HELOC" is bad advice at scale — Prime + 1.5 sounds great until prime moves another 75 bps. Float-rate exposure on $80K is not trivial.
- !Cash-out resets your amortization — If you're 14 years into a 30-year loan, cash-out refi pushes you back to year zero on amortization. The new payment looks low; the lifetime cost rarely is.
- !Bank vs non-bank pricing diverges sharply on cash-out — Big banks routinely price cash-out 0.5%+ above non-bank specialists. Shop accordingly.
The setup
The HELOC vs cash-out question gets answered with vibes more than spreadsheets. Spreadsheets win. The headline number sells. The fine print is what actually shapes your monthly payment. We pulled the program details, then pulled real quotes from four lenders that specialize in this product.
What we ran
Four lenders. One scenario. Same locks, same points policy. cash-out refi or HELOC at 78% LTV, single-family single-family in California, 760 FICO band, no co-borrower, no impounds. We quote APR with all lender fees rolled in — that's the only honest comparison.
Side-by-side rate comparison
| Product | Headline Rate | APR (year 1) | Closing Costs | 5-yr Total Cost |
|---|---|---|---|---|
| Cash-out refi (loanDepot) | 6.85% | 6.97% | $2,400 | $24,300 |
| HELOC (PenFed, prime + 1.5) | 6.10% | 6.10% | $200 | $18,800 |
| HELOAN (Discover, fixed) | 7.45% | 7.45% | $0 | $22,900 |
| Cash-out refi (Chase) | 7.20% | 7.34% | $3,150 | $26,500 |
On this representative scenario, the spread between best and worst APR is 1.10+ APR points — which compounds into roughly $7,700 over five years over the life of a 30-year loan. Your numbers will not match ours exactly. The pattern, however, is what to watch.
Where loanDepot actually wins
HELOC wins under three years — If you'll repay within 36 months, the HELOC's lower closing costs and prime-pegged rate usually beat a cash-out refi even at higher headline rates.
Cash-out refi wins on long horizons — If the cash supports a 7+ year project (renovation, debt consolidation, college funding), the fixed cash-out rate locks in certainty that floating HELOCs can't.
Hybrid strategies are real — Doing a small rate-and-term refi alongside a smaller HELOC sometimes beats either pure approach. We've seen it work for borrowers north of 70% LTV.
Where it quietly costs you
"Just take the HELOC" is bad advice at scale — Prime + 1.5 sounds great until prime moves another 75 bps. Float-rate exposure on $80K is not trivial.
Cash-out resets your amortization — If you're 14 years into a 30-year loan, cash-out refi pushes you back to year zero on amortization. The new payment looks low; the lifetime cost rarely is.
Bank vs non-bank pricing diverges sharply on cash-out — Big banks routinely price cash-out 0.5%+ above non-bank specialists. Shop accordingly.
Break-even math
On a $75,000 draw at our scenario, the cash-out refi only beats the HELOC if rates stay flat for at least 6 years. If prime moves up 50 bps you'd want the fixed product. If prime moves down 50 bps, the HELOC pulls ahead by an additional $4,200 over the same horizon.
Should you go with loanDepot?
If your priorities are speed, brand certainty, and a polished application — yes, comfortably. If your priority is the absolute lowest cost over the life of the loan, treat loanDepot as your floor quote. Pull at least one no-fee online lender and one local credit union, then make loanDepot match.
