CD vs Paying Off HELOC (2026): Variable Rate Crushes Fixed Yield
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.
CD vs MYGA, after tax
What $100,000 earns in 5 years: CD vs MYGA, after tax
Rates used: CD 4.50%, the top nationally available 5-year CD (DepositAccounts, September 24, 2026); change it to the rate you are offered. MYGA 5.95%, the best A-rated rate we track as of October 13, 2026: Delaware Life Pinnacle Plus 5-year (AM Best A-, negative outlook, 7/31/2026), $100,000 and up, effective October 6, 2026 (Delaware Life rate sheet).
| CD, interest taxed every year | $118,826 |
|---|---|
| MYGA, tax-deferred, before tax | $133,507 |
| MYGA after paying tax on all the interest at withdrawal | $126,136 |
| Tax deferral alone adds about | $674 |
| MYGA ahead of the CD, after tax | $7,310 |
Assumes 22% federal and 0% state income tax, no withdrawals, rates held for the whole term. MYGA interest is taxed as ordinary income when you withdraw it, not as capital gains. Gains taken before age 59 1/2 can owe a 10% IRS penalty, and cashing out early can cost a surrender charge. In an IRA both grow tax-deferred, so the edge there is the rate alone. Bank and credit union deposits are FDIC or NCUA insured up to the limits; a MYGA is backed by the issuing insurer's claims-paying ability and your state's guaranty association up to its limits, not the FDIC.

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.
