GLWB Income Rider vs SPIA Annuitization — Lifetime Income Compare

TL;DR: Both deliver guaranteed lifetime income. SPIA usually pays more per dollar because you give up principal access forever. GLWB pays less per dollar but preserves account value that may pass to heirs (after the rider fees have done their damage). This calculator shows exact total income and residual values across both routes.

Compare current GLWB vs SPIA quotes

SPIA usually pays more per dollar (no rider fee, no death benefit). GLWB pays less but preserves account value that may pass to heirs. Rider fees compound against the account value and can deplete it — after which the carrier continues paying the guaranteed income from its own reserves.

How this calculator works

SPIA total income = SPIA monthly × 12 × years. SPIA is annuitized at issue — principal is gone. No residual.

GLWB total income = GLWB monthly × 12 × years. Account value still exists, projected as:

Each year, account value = prior balance × (1 + credit rate) × (1 - rider fee) - GLWB income drawn.

If account value depletes to zero before the period ends, the carrier continues paying the GLWB income from its own reserves (guaranteed feature of GLWB riders).

Residual at end = the account value remaining after all years of fees and withdrawals. If positive, that money passes to heirs at death.

What the result means

GLWB total income over the period is usually 5-15% lower than SPIA — the cost of the rider fee and the lower payout rate.

SPIA total income is the higher monthly check × full years. No residual.

GLWB residual is the dollar amount remaining in the account that passes to heirs. For typical scenarios (4-5% credited rate, 1.10% fee, 6.5% withdrawal), the residual depletes around year 18-22.

If you live longer than the residual lasts, the GLWB guarantee kicks in — you keep getting the income but heirs get nothing. So GLWB's heir benefit depends on dying early enough.

When MYGA wins / when the alternative wins

SPIA wins when: you want the absolute maximum lifetime income, have no heirs (or don't care about leaving money), and want the simplest structure.

GLWB wins when: you want lifetime income BUT want to preserve some account value for heirs, you're comfortable with rider fees, and the carrier offers a strong rider.

Neither wins when: you have other income sources covering the floor and want maximum growth/liquidity. Then a MYGA or balanced portfolio beats both.

Worked example

Scenario: 65-year-old, $300,000 premium, plans for 20 years of income (to age 85).

GLWB payout: 6.5%. Monthly = $1,625. Annual = $19,500.
SPIA payout: 6.6%. Monthly = $1,650. Annual = $19,800.
GLWB rider fee: 1.10%/yr. FIA credits 4.5%/yr.

Over 20 years:

GLWB total income: $19,500 × 20 = $390,000. Residual at year 20: ~$25,000 (depending on actual credit performance).
SPIA total income: $19,800 × 20 = $396,000. Residual: $0.

SPIA wins on income by $6,000. GLWB wins on residual by $25,000 (if she dies at 85). Net wealth wins GLWB by $19,000 — if she dies on schedule. If she lives to 95, GLWB residual is long gone and SPIA's extra $6K x extended years adds up.

Common mistakes

Comparing GLWB payout rate to SPIA payout rate directly. GLWB pays on the BENEFIT BASE (often 5-7% rolled up), not the account value. SPIA pays on premium directly. Different bases — do the dollar math.
Forgetting rider fees compound. 1.10%/yr sounds small but eats 19% of account value over 20 years even before withdrawals.
Assuming residual will be substantial. Most GLWB account values deplete to zero around year 18-22 of withdrawals. Heirs often get little.
Buying GLWB without intent to use it. Rider fees apply whether you turn on income or not. Many buyers pay fees for years and never activate.
Ignoring the bonus. Many GLWB products have a benefit-base bonus (e.g., 30% Allianz 222 PIV bonus) — can swing the GLWB math significantly. Make sure to use the bonused benefit base for income calc.

FAQ

Q: What is GLWB?
A: Guaranteed Lifetime Withdrawal Benefit — a rider on a deferred annuity that promises a level lifetime income at a specified % of the benefit base, regardless of account value performance. Costs 0.85-1.50%/yr in rider fees.

Q: What is SPIA annuitization?
A: Single Premium Immediate Annuity. You hand over premium and receive a guaranteed lifetime monthly check. No more access to principal. Highest income per dollar.

Q: Can I cancel the GLWB rider?
A: Some carriers allow you to drop the rider in exchange for stopping the fees. Once dropped, you can't add it back. Once income is turned on, can't be dropped.

Q: What's the 'benefit base' on a GLWB?
A: A separate accounting figure (not real cash) that grows at a guaranteed rate (often 5-7%/yr) during deferral. The GLWB lifetime income is a % of this base, not the cash account value.

Q: Does SPIA pay more than GLWB?
A: Usually yes per dollar of premium because SPIA gives up principal access. GLWB preserves the cash account value (which may pass to heirs after fees).

Q: What if I die before the GLWB account value depletes?
A: Account value passes to heirs as a death benefit. GLWB income stops.

Q: What if I live past GLWB depletion?
A: Carrier continues paying GLWB income for life from its reserves. Heirs get zero. This is the longevity-insurance feature of the rider.
