You walk into a financial advisor's office with $200,000 saved for retirement. They offer you two products: a fixed annuity that guarantees 4% annual growth with zero market risk, or a variable annuity that could earn 7–9% but charges 3.2% in annual fees. Which one piles more cash in your pocket by age 85? The answer depends on time horizon, inflation, and sequence-of-returns risk—not the glossy brochure promises. This article compares the long-term math behind fixed vs. variable annuities, reveals where the industry buries its profit centers, and shows you how to benchmark your own annuity contract against a DIY portfolio of index funds.
Annuity providers quote you a monthly payout figure—say $1,200 per month from a $200,000 fixed annuity. That number sounds concrete, but it masks the true cost of owning the contract. Fixed annuities typically charge no explicit annual fee but recoup costs through the spread between what they earn on their bond portfolio and what they credit to your account. That spread is often 1.5% to 2.5% per year, hidden in the fine print as the 'administrative expense.' Variable annuities, meanwhile, advertise a menu of sub-accounts but attach mortality and expense (M&E) fees of 1.1% to 1.6%, plus underlying fund fees of 0.5% to 1.2%.
Take a real example: a $200,000 variable annuity from a major insurer charges a 1.4% M&E fee, a 1.0% fund fee, and a 0.2% rider fee for a guaranteed lifetime withdrawal benefit (GLWB). That's 2.6% total. If the sub-accounts gross 8% annually, your net return is 5.4%. A fixed annuity crediting 4.5% gross may net 4.5% if the insurer takes its spread from the bond return rather than a direct deduction on your account value. Over 20 years, the variable annuity starting at $200,000 grows to $571,000 at 5.4%—while the fixed annuity reaches $482,000 at 4.5%. The gap is $89,000, or roughly $128,000 if you factor in inflation-adjusted spending power at 3% annual inflation.
GLWB riders let you withdraw a fixed percentage (typically 4–6%) of your 'benefit base' each year, regardless of market performance. The benefit base is not your actual account value—it grows at a guaranteed rate (5–7%) for a deferral period. The catch: the rider costs 0.6% to 1.2% of your account value annually. If your variable annuity account grows at 5% after fees and the rider costs 1%, you need to decide whether the downside protection justifies the drag.
Consider a 60-year-old with $200,000. With a 6% GLWB and 5% guaranteed growth on the benefit base over 10 years, the benefit base rises to $325,000. The annual withdrawal becomes $19,500. Meanwhile, the actual account value—net of the 1% rider—grows at 4% post-fees to $296,000 by year 10. You are now withdrawing 6.6% of your actual account each year, which may deplete the account by age 85. Without the rider, a variable annuity earning 5% after all other fees yields $325,000 at year 10. If you take a 5.5% withdrawal ($17,875), the account may last to age 90. The GLWB provides certainty but costs about $2,000 per year in fees on the $200,000 account. Over 20 years, that is $40,000 in rider fees—and potentially $60,000 lower ending balance.
Fixed annuities tout safety, but they pay nominal returns. If inflation averages 3% annually, a 4% fixed annuity yields a real return of just 1%. Over 20 years, inflation cuts $200,000 to $110,000 in today's spending power. The fixed annuity's principal appears intact, but you can only buy half as much with it. Variable annuities, with equity-linked sub-accounts, historically earn 6–8% nominal, leaving 3–5% real. The trade-off: you accept volatility. In years where stocks drop 30%, your variable annuity may drop 28% after fees—painful if you need to withdraw during a downturn. That is the sequence-of-returns risk that makes fixed annuities appealing to risk-averse retirees. However, a multi-year guaranteed annuity (MYGA) fixed-rate product can lock 5% for five years in 2025, beating inflation in the short term. But once the guarantee period ends, renewal rates typically revert to lower prevailing rates.
The optimal approach splits the difference: use a fixed annuity to cover essential expenses for years 1–5 of retirement, and a variable annuity for discretionary growth. But buying both means paying two sets of fees. A simpler alternative: a low-cost fixed indexed annuity (FIA) that credits a portion of stock index gains with a floor of 0%. FIA fees average 1.0–1.5%, with caps on participation. In 2025, an FIA with a 75% participation rate on the S&P 500 and a 0% floor might yield 6.5% in a year the index returns 9%—but you still pay fees, and you miss the other 25% of gains.
Fixed and variable annuities both impose surrender charges—a sliding fee if you withdraw more than a certain percentage (often 10% per year) during the first 7–10 years. Typical surrender schedules: 7% in year one, declining 1% each year. On a $200,000 contract, a full withdrawal in year two costs $12,000. Variable annuities often offer a 'free withdrawal' provision of 10% annually without penalty. Fixed annuities might allow only the interest or a 5% free withdrawal. In an emergency, that illiquidity can force you to pay penalties or take a loan from the annuity at 5–6% interest—costing you more than a bank loan.
Let's model two scenarios with $200,000 and 20-year horizon. Scenario A: A fixed annuity with 4.5% gross return, no explicit fee, but a 1.5% implied spread—so net 3.0%. No rider. Withdraw $1,000 per month adjusted for 3% inflation starting year one. The account is empty by year 18. Scenario B: A variable annuity with 2.6% total fees, gross return 8%, net 5.4%. Withdraw the same $1,000 (inflation-adjusted). The account holds $87,000 at year 20. The difference in ending value: $87,000 vs. $0. If you instead take a 5% fixed withdrawal of $10,000 per year (no inflation adjustment), the fixed annuity ends at $143,000, the variable annuity at $272,000—a $129,000 gap. But if you increase the variable annuity fee by another 0.5% (common for added living benefits), the gap shrinks to $95,000.
The winner is clear for long horizons: lower-fee variable annuities with market exposure. But for short horizons (10 years or less), a fixed annuity with a guaranteed 4.5% and no market risk leaves you ahead, assuming you do not need the money early. The $128,000 figure assumes a full 20-year growth path with no catastrophic market crash. In a 2008-repeat scenario—30% drop in year one—the variable annuity drops to $140,000 after fees, while the fixed annuity stays at $200,000. The variable annuity takes 4 years to recover, during which you might have withdrawn more than the contract can sustain. Sequence risk is real.
Run your numbers through a Monte Carlo simulator (tools like Portfolio Visualizer or MoneyGuidePro offer free versions). Input your annuity's fee load, withdrawal rate, and a portfolio of 60% stocks/40% bonds for the variable option. Compare the probability that your money lasts to age 95. If the fixed annuity shows a 90% success rate and the variable shows 80%, the fixed may be worth the lower ceiling. But if variable shows 95% success and fixed shows 85%, the math tilts toward variable.
You do not need to buy an insurance product to get guaranteed income. A 'do-it-yourself annuity' uses a ladder of Treasury bonds, CDs, or SPIA shares (a single-premium immediate annuity purchase) to create a predictable cash flow. For $200,000, you could buy a five-year CD ladder earning 4.8% in 2025, yielding $9,600 annual interest with FDIC insurance—zero fees, zero surrender charges. The difference from a fixed annuity: you hold the principal and can adjust withdrawals. The downside: interest rates may drop at renewal, and you take reinvestment risk. Pair the CD ladder with a variable annuity for growth to create a 'bond tent' strategy: the fixed cash covers early spending, while equities grow untouched until later years. The fee savings alone—2.5% vs. 0.06%—on a $200,000 portfolio over 10 years amounts to $48,700 in extra returns (assuming 6% growth on the fee difference).
Before signing any annuity contract, ask your financial advisor or the insurance agent for a single-page document showing the cumulative fees—in dollars—over years 1, 5, 10, 15, and 20. Insist on a projection that includes the net return after all expenses, not just the gross illustration. If they cannot provide it, that is a red flag. Then compare those numbers to a simple ETF portfolio at a brokerage like Vanguard or Fidelity. You can also visit the National Association of Insurance Commissioners (NAIC) free annuity buyer's guide to check surrender terms and fee disclosures by contract type. If the fixed annuity's guaranteed income covers your bare-bones expenses and you sleep better, it may be worth the $128,000 gap in potential growth. But if you have a 20-year runway, the variable annuity—or the DIY alternative—likely leaves you with a six-figure larger nest egg.
