CD vs Paying Off HELOC (2026) - Variable Rate Crushes Fixed Yield

TL;DR: HELOCs reset monthly at Prime + margin - currently Prime is 8.50%, plus a typical 0.50-1.50% margin = 9.00-10.00% all-in rate. A 5-year CD pays 4.40%. Paying off the HELOC saves 9-10% guaranteed; the CD earns 4.40% taxable. The HELOC payoff wins by 500+ basis points. The only reason to keep HELOC debt is if rates are about to fall sharply.

This is the easiest decision on the page. HELOC rates in 2026 sit at Prime (8.50%) plus a typical margin of 0.50-1.50%, putting effective rates at 9.00-10.00%. CDs yield 4.40%. Paying down the HELOC eliminates a guaranteed 9-10% cost; the CD generates 4.40% gross / 3.20% net.

This isn't a close call. The HELOC payoff wins by 580-680 basis points after-tax. The only argument for keeping HELOC debt and investing in CDs instead: you expect Prime to fall sharply (Fed cuts of 300+ bps) within months. Even then, the math during the wait is against you.

Side-by-side comparison

Dimension	CD	Pay Off HELOC
'Yield' (2026)	4.40% gross, ~3.20% after tax	9.00-10.00% saved interest (Prime + margin)
Rate type	Fixed for term	Variable - resets monthly
Rate direction risk	CD locked at 4.40% even if rates rise	HELOC rate rises if Prime rises - cost climbs
Tax deductibility	Interest taxable	Generally NOT deductible unless used for home improvement (TCJA rules)
Liquidity	Penalty for early withdrawal	Pay down, but can re-borrow through HELOC unused capacity
Reversibility	Can withdraw at maturity	Can re-borrow against HELOC unless bank closes the line
Risk	FDIC to $250K	None - payoff is risk-free
HELOC line closure risk	N/A	Banks can freeze/close HELOC lines in stress (2008 lesson)
Best for	Liquidity scarcity, expecting big rate cuts	Almost any other situation
Inflation impact	Locked yield, no upward adjustment	Variable cost moves with rates
Behavioral risk	Money stays accessible	Tempting to re-borrow once line is paid down

When CDs win

You're certain rates will fall 200+ bps within 6 months. Even then, the math is marginal.
You don't have an emergency fund and the HELOC is your only liquidity backstop. Don't pay it off if doing so leaves you with no cash for emergencies.
You're about to sell the property and the mortgage/HELOC will be cleared at closing. Short-term liquidity preserved makes sense.
Your HELOC is at a teaser introductory rate (e.g., 5% intro for 12 months). While teaser is active, the spread shrinks. Re-evaluate when teaser expires.
You used the HELOC for home improvement and need ongoing draws against it. Don't pay down what you'll re-borrow next month.

When Pay Off HELOC wins

Your HELOC is at variable Prime + margin (the normal structure). Pay it down. Almost no scenario where keeping it makes sense.
Your HELOC was used for non-deductible purposes (debt consolidation, vacation, college). No tax shield, full pre-tax cost. Pay it down.
You have ample emergency liquidity elsewhere. No reason to keep an expensive open balance.
You're approaching retirement. Reduce monthly debt obligations before fixed-income retirement begins.
You're concerned about bank stress that could trigger HELOC line freezes. Pay down (don't close - keeping the line open as backup is fine, just at zero balance).

Worked example: $250,000 over the planning horizon

You have $150,000 cash and a $150,000 HELOC balance at Prime + 1.00% = 9.50%. Your monthly interest-only payment is currently ~$1,188. Two strategies:

Option A: $150K into a 5-year CD at 4.40%.
CD interest: $6,600/yr gross / $4,686 after 24% federal + 5% state. HELOC interest cost: $14,250/yr (at current 9.50% rate). Net cost: $9,564/yr.

Option B: $150K to pay off HELOC.
HELOC balance = $0. Interest cost: $0. Free cash flow improvement: $1,188/mo / $14,250/yr. CD interest forgone: $4,686/yr. Net benefit: $9,564/yr improvement vs Option A.

The payoff saves you $9,564/year compared to keeping the cash in a CD - and that's at current Prime. If Prime rises to 9.00% (HELOC = 10.00%), the savings widen further. If Prime falls to 7.00% (HELOC = 8.00%), savings narrow but still favor payoff.

Keep the HELOC line OPEN at zero balance after payoff. It's a free standby liquidity source. Just don't pay 9.50% interest on a balance you can eliminate today.

Tax implications

CD interest: taxable as ordinary income annually.

HELOC interest: under the 2017 tax law (TCJA), HELOC interest is deductible only if the loan proceeds were used to "buy, build, or substantially improve" the home that secures the loan. HELOC interest used for debt consolidation, college expenses, vacation, or general personal spending is not deductible. The HELOC must be tracked-use to claim any deduction.

For most HELOC borrowers, the interest is fully non-deductible, making the gross rate the comparison. At 9.50% non-deductible HELOC vs 4.40% taxable CD (3.20% after-tax), the math overwhelmingly favors payoff.

Frequently Asked Questions

Should I close the HELOC after paying it off?

No. Keep it open at zero balance. The line is free standby liquidity. Banks sometimes close inactive HELOCs after 12-24 months - draw $100 once a year if needed to keep it active.

What if my HELOC has a fixed-rate option?

Some HELOCs allow you to convert all or part of the outstanding balance to a fixed-rate term (5-15 years) at a stated rate. If the fixed-rate option is below CD yields (rare in 2026), it might make sense to lock and keep. Compare carefully.

Is mortgage payoff or HELOC payoff a higher priority?

HELOC almost always. HELOCs are variable (climbing in rising-rate environments), often higher rate (Prime + margin vs fixed mortgage rate), and frequently non-deductible. Pay HELOC first, mortgage second.

What if I'm in a HELOC draw period vs repayment period?

During draw period (typically first 10 years), payments are interest-only on the outstanding balance. During repayment period (typically next 10-20 years), payments include principal and interest. Both have the same arithmetic for the payoff comparison.

Should I refi the HELOC into a fixed-rate second mortgage?

Sometimes. Fixed-rate second mortgages are currently around 8.5-9.5% - similar to HELOC rates but locked. If you can't pay off the balance and want rate certainty, refinancing to fixed makes sense. Compare closing costs.

What about HELOCs at promotional intro rates?

Intro rates (often 4-5% for 6-12 months) are real but temporary. Don't get used to the payment. Plan to refinance or pay down before the intro period ends.

Can I lose the HELOC line if I pay it down?

Banks sometimes reduce or close inactive lines. Keep it active with occasional small draws. Don't formally close it unless you're sure you won't need it - reopening requires a new application and may not be approved.
