MYGA vs CD After-Tax Calculator — State & Bracket Aware (2026)

TL;DR: CDs get taxed every year. MYGAs defer all gains until withdrawal. That single difference is worth $5K-$30K on a 5-year, $250K deposit for anyone in a 22%+ bracket. Higher brackets and state-income-tax states (especially California) widen the gap dramatically. Enter your state, bracket, and the two rates — see the dollar advantage instantly.

CD interest is taxed every year as it's credited. MYGA interest is tax-DEFERRED until withdrawal. Even at the same headline rate, deferral lets the MYGA compound on a larger base. The advantage grows with bracket, state rate, and term.

How this calculator works

Two different tax mechanics are at play:

CD math (taxed yearly):

Net = P × (1 + r×(1-t))^n

Every dollar of interest gets taxed in the year it's credited, so your effective compound rate is the gross rate times (1 minus your combined tax rate).

MYGA math (tax-deferred):

Gross = P × (1 + r)^n
Net = P + (Gross - P) × (1 - t)

The full nominal rate compounds untouched for the entire term. Only at withdrawal is the gain taxed — once, at your then-current bracket. You can also stagger withdrawals across years to manage bracket creep.

The combined tax rate t = federal + state. CA at the 9.3% bracket plus 24% federal = 33.3% — that's a brutal yearly haircut on CD interest, and exactly why deferral matters most in high-tax states.

What the result means

The big number is MYGA's net dollar advantage over the same-deposit CD held for the same term, after all taxes are paid. Positive = MYGA wins. Negative = CD wins.

For most realistic scenarios in 2026, MYGA wins. The gap grows with:

Tax bracket. A 12% bracket gets minimal benefit from deferral. A 32%+ bracket gets significant benefit.
State tax. No-tax states (FL, TX, NV) cut the deferral edge in half. High-tax states (CA, NY top, NJ) amplify it.
Term length. 3-year MYGA vs 3-year CD = modest advantage. 10-year MYGA vs 10-year CD = massive advantage because compounding has time to work.
Rate spread. If the MYGA is already paying more than the CD (typical in 2026, 100-200 bps), the after-tax gap widens even further.

When MYGA wins / when the alternative wins

MYGA wins decisively when: CA / NY / NJ resident in a 24%+ federal bracket, 5+ year horizon, deposit $100K+. Common advantage: $15K-$50K over 5 years on $250K.

CD wins when: 0-12% federal bracket, no-state-tax state, term under 3 years. The deferral mechanic doesn't have enough room to overcome any rate gap.

Treasury ladder wins when: You're in CA/NY/OR top bracket AND need monthly cashflow you can't get from a deferred wrapper. State-tax exemption on Treasuries is its own form of "deferral" — for state tax only.

Tie scenarios: 3-year horizon, 22% federal, ~5% state. Run the numbers exactly. Often the deciding factor isn't tax — it's whether you actually need the liquidity that the CD offers.

Worked example

Scenario: 67-year-old Sacramento retiree, $250,000 to park for 5 years.

CD rate (5-yr brokered): 4.40%
MYGA rate (5-yr, A-rated): 5.85%
Federal bracket: 24%
CA state: 9.3%
Combined: 33.3%

CD after-tax: $250,000 × (1 + 0.044×0.667)^5 = $250,000 × (1.02935)^5 = $288,930. Gain = $38,930.

MYGA after-tax: Gross = $250,000 × 1.0585^5 = $332,460. Gain = $82,460. Tax = $82,460 × 0.333 = $27,460. Net = $250,000 + $55,000 = $305,000.

MYGA wins by $16,070 — 6.4% of original principal — over 5 years. And if she stages withdrawals over 2-3 years to stay in the 22% bracket, that gap widens by another $4-6K.

Common mistakes

Forgetting state tax. Federal-only comparisons make CDs look better than they are. CA, NY, NJ residents in particular get burned.
Assuming "same rate" = "same outcome." Even at identical rates, MYGA wins on after-tax due to deferral compounding.
Comparing CD to non-qualified MYGA when the money's in an IRA. Inside an IRA, both are already deferred — comparison is pure rate.
Underestimating bracket creep at withdrawal. If you withdraw $80K of MYGA gain in one year, you may push into the next bracket. Stagger withdrawals across 2-3 years to manage this.
Skipping the renewal-rate question on the MYGA. A "MYGA" with a 1-year guarantee and 4 years of renewals is not the same product; nominal rate doesn't lock.

FAQ

Q: Is MYGA always better than a CD?
A: For taxable money held 3+ years by anyone in a 22%+ bracket, almost always. For under-3-year horizons or 0-12% brackets, CDs are competitive.

Q: How is California different?
A: CA has the highest state income tax in the nation (up to 13.3%). Every dollar of CD interest gets clipped twice (federal + CA). MYGA defers both clips until withdrawal — and you can stage withdrawals to lower-income years.

Q: What's the catch on the MYGA tax?
A: Withdrawals before age 59½ get a 10% IRS penalty on the gain portion. After 59½, just ordinary income tax on gains as they come out.

Q: Are MYGAs FDIC-insured?
A: No. MYGAs are insurance contracts backed by the carrier and state guaranty associations (typically $250K-$500K per carrier per state). FDIC covers CDs to $250K per bank per ownership category.

Q: Why not just use a Treasury ladder?
A: Treasuries are state-tax-exempt but federally taxed yearly. For CA top-bracket folks, a 5-year MYGA at 5.85% deferred typically still beats a Treasury ladder around 4.20% after both fed and state math.

Q: Can I get a 10% withdrawal without penalty?
A: Yes — almost all MYGAs allow 10% of account value withdrawn per year free of surrender charge. IRS penalty on gain still applies if you're under 59½.

Q: Does the tax rate at withdrawal matter?
A: Yes. If you plan to withdraw in retirement when you're in a lower bracket, the deferral advantage grows. Many high-earners use MYGAs to time-shift income from peak-earning years to lower-bracket retirement years.
