Variable annuities are often sold on the promise of one compelling idea: you can participate in market gains without bearing the full risk of market losses. It’s an attractive pitch, especially for investors approaching retirement who can’t afford a major setback. However, the word “guarantee” inside a variable annuity contract carries a lot of fine print. Understanding exactly what it protects, what it costs and how the mechanics actually work can mean the difference between a smart retirement income strategy and an expensive misunderstanding.

A financial advisor can help you assess whether variable annuities are right for your portfolio based on your retirement goals.

What Does a Variable Annuity Actually Guarantee?

A variable annuity is a contract between you and an insurance company 1 . You invest your money in market-linked sub-accounts, meaning your returns can go up or down. What makes variable annuities distinct is that, despite that market exposure, they can still offer a layer of financial protection. It comes from built-in or optional guarantees that help reduce investment risk.

At the most fundamental level, a variable annuity guarantees that your beneficiaries will receive at least what you put in. Known as the standard death benefit, it ensures that if you die before beginning withdrawals, your heirs won’t receive less than your original investment, regardless of how the market performs 2 .

Beyond the death benefit, many variable annuities offer optional living benefit riders that protect you while you’re still alive. Although they vary, they generally guarantee either a minimum income stream, a minimum withdrawal amount or a minimum account value. This is often for an additional annual fee ranging from 0.25% to 1.5% or more 3 .

The Four Types of Variable Annuity Guarantees

Variable annuities can include several distinct types of guarantees. Each helps protect a different aspect of your financial picture. Understanding what each one covers and its costs is essential before committing to a contract.

1. Guaranteed Minimum Death Benefit (GMDB)

The guaranteed minimum death benefit is the baseline protection included in virtually every variable annuity 4 . It ensures that if you die during the accumulation phase, your beneficiaries receive at least the amount you originally invested, even if the account has lost value.

Some contracts enhance this by locking in the highest account value reached on specific anniversaries, giving heirs a potentially larger payout.

2. Guaranteed Minimum Income Benefit (GMIB)

A guaranteed minimum income benefit is an optional rider that guarantees you can convert your contract into a stream of income 5 . This is annuitization, and it uses a minimum benefit base, regardless of the account’s actual performance.

This can be a good idea if markets perform poorly heading into retirement. This is because your income payments are calculated based on a floor value rather than your account’s actual value. The tradeoff is that you typically must annuitize to access the benefit, surrendering control of your principal.

3. Guaranteed Minimum Withdrawal Benefit (GMWB)

The guaranteed minimum withdrawal benefit allows you to withdraw a set percentage of your benefit base each year until you’ve recouped your entire original investment 6 . This applies even if market losses have reduced your account value to zero.

Unlike the GMIB, this rider doesn’t require annuitization. It gives you more flexibility over how and when you access your money. However, withdrawals above the guaranteed amount can reduce or eliminate the benefit.

4. Guaranteed Minimum Accumulation Benefit (GMAB)

The guaranteed minimum accumulation benefit promises that your account value will be at least equal to a specified amount, often your original investment, after a defined holding period 7 . This typically lasts seven to ten years. If the market has underperformed, the insurance company makes up the difference.

This rider appeals to investors who want market participation but need assurance that they won’t fall below their initial investment over the long run.

Understanding the Benefit Base vs. Account Value

One of the most misunderstood aspects of variable annuities is the difference between the benefit base 8 and the account value. Confusing the two can lead to serious miscalculations about how much money you actually have.

The account value is the actual dollar amount in your annuity at any given time. It rises and falls based on the performance of the sub-accounts you’ve chosen. These are typically invested in mutual fund-like portfolios tied to stocks, bonds or other assets. This is the number that reflects your true wealth inside the contract.

The benefit base is a separate, hypothetical figure used only to determine the size of your guaranteed benefits 9 . It is not money you can withdraw as a lump sum, transfer to another account or leave to heirs in full. Think of it as the measuring stick the insurance company uses to calculate what they owe you under a specific rider.

Depending on your contract, the benefit base may grow in several ways. Some contracts offer a simple annual roll-up rate (often 5% to 7%) that increases the benefit base each year you defer withdrawals, regardless of market performance 10 . Others use a step-up feature that locks in your highest account value on contract anniversary dates, resetting the benefit base upward if markets have performed well.

Salespeople sometimes emphasize benefit base growth when presenting variable annuities. However, this can make the product sound more lucrative than it is. A rising benefit base does not mean your investable assets are growing at that same rate.

Understanding this distinction helps you evaluate whether these guarantees are actually worth the cost. It is a conversation well worth having with a financial advisor before signing any contract.

What Variable Annuity Guarantees Cost

Variable annuity guarantees don’t come free. They have a layered fee structure that can quietly erode your returns over time. Before purchasing a contract, it’s worth understanding exactly what you’re paying and how those costs compound across the life of the annuity.

Every variable annuity carries a mortality and expense risk charge, commonly called the M&E fee 11 . This is the insurance company’s base charge for providing the contract and its baseline guarantees. It typically runs between 0.5% and 1.5% of your account value annually 12 . It applies regardless of whether you add any optional riders.

Each optional guarantee rider (whether a GMWB, GMIB or GLWB) comes with its own annual fee, usually ranging from 0.50% to 1.50% or more. These charges are typically assessed against your benefit base rather than your account value. This means you could end up paying fees on a larger number than what your account is actually worth. Adding even one rider can meaningfully increase your total annual cost.

The sub-accounts inside a variable annuity function similarly to mutual funds. Like mutual funds, they carry their own internal expense ratios, typically ranging from 0.50% to over 1.50% annually.

They’re often embedded in the sub-account’s performance rather than listed as a separate line item. Therefore, many investors don’t realize they’re paying them at all.

Bottom Line

Variable annuities occupy a unique space in retirement planning. They offer market-linked growth potential alongside contractual guarantees that can protect your income, investment or beneficiaries, depending on the riders you choose. The four core guarantee types (GMDB, GMIB, GMWB and GMAB) each address a different risk. Meanwhile, the benefit base mechanic is the engine that powers most of those protections. That security comes at a real cost, though, one that can reach 3% to 4% annually with all fees combined.
