Guaranteed Lifetime Withdrawal Benefit (GLWB)

Guaranteed Lifetime Withdrawal Benefit (GLWB)

A Guaranteed Lifetime Withdrawal Benefit (GLWB) is an optional rider you add to an annuity contract that guarantees you can withdraw a set percentage of your benefit base every year for the rest of your life, even if the annuity's account value falls to zero. You pay an annual fee for the rider, typically between 1% and 3% of the benefit base. The insurance company continues making payments for as long as you live, funded by the insurer's reserves once your account is depleted.

Fidelity offers GLWBs on variable annuities through third-party insurance companies including Nationwide Life Insurance and Pacific Life. Morningstar describes a GLWB as a way to get lifetime income without requiring the irrevocable annuitization that locks you out of your account permanently.

How the Math Works

A GLWB tracks two values simultaneously. Your account value is the real cash value of the annuity, moving with the market and subject to withdrawal and fee deductions. Your benefit base is a separate calculation value used exclusively to determine your guaranteed annual withdrawal amount.

Think of the benefit base as a scorecard, not a bank account. You cannot withdraw the benefit base as a lump sum, but the insurer uses it to calculate how much you receive every year for life.

Most contracts set your annual withdrawal as: Benefit Base × Payout Percentage = Annual Guaranteed Income. The payout percentage rises as you age. A 60-year-old might receive 4% of the benefit base annually, while a 70-year-old might receive 5.5%. Choosing joint coverage for a spouse reduces the payout percentage to reflect two lifetimes of payments.

What Happens When the Account Hits Zero

If you live long enough and make regular withdrawals, your account value will eventually reach zero. At that point, the insurance company continues making your guaranteed annual payments from its own reserves. This is the core value proposition of the GLWB: the insurer absorbs the longevity risk that you might outlive your assets.

Annuity.org emphasizes that this guarantee holds only if you stay within the prescribed withdrawal limits. Taking withdrawals above the guaranteed amount triggers a recalculation that permanently reduces future guaranteed income. The GLWB functions as an income lane, not a blanket permission to withdraw whatever you want.

Benefit Base Growth Features

Many GLWB contracts include features that increase the benefit base over time.

  • Step-up or ratchet feature: On each contract anniversary, the insurer compares your account value to your benefit base. If your account value is higher, the benefit base steps up to match it, permanently locking in market gains.
  • Roll-up rate: Some contracts guarantee the benefit base grows at a minimum rate, often 5% to 7% annually compounded, during a deferral period before you begin withdrawals. This lets you maximize future income by waiting to take withdrawals.

GLWB vs. Income Annuity: The Control Trade-Off

An income annuity converts your balance into a guaranteed income stream permanently. You give up control of the assets, but you typically receive higher monthly payments than a GLWB provides on the same premium.

A GLWB lets you keep control of your account. You can make additional withdrawals beyond the guaranteed amount, change investments within the subaccounts, and pass any remaining account value to beneficiaries. Morningstar notes that this flexibility comes at a price: GLWB income is generally lower than what an income annuity delivers on the same premium because the insurer is compensating you for the retained liquidity.

The Fees Make the Math Less Obvious

GLWB riders add annual charges on top of the base annuity expenses. A typical variable annuity already carries mortality, expense, and administrative fees of 1% to 1.5% annually. Adding a GLWB rider pushes total annual costs to 2.5% to 4.5% of the account value.

Thrivent Financial notes these costs compound over a 20-year deferral period, significantly reducing the net return on your investment account. You need to model the break-even point: how long must you live and draw income before the guaranteed lifetime payments exceed what you paid in fees?
