Insurance companies make money on annuities mainly through the investment spread: they invest your premium at one rate and credit your contract at a lower one, keeping the difference. On a fixed annuity that gap typically runs about 1.5% to 2.5% a year. Layered on top are mortality assumptions, internal fees deducted from your account, surrender penalties in the early years, and, on indexed products, crediting formulas that cap how much of the market’s upside reaches you. Understanding how annuities make money is the fastest way to judge whether a given contract’s guarantees are worth what you’re paying for them.
The Investment Spread Is the Main Engine
When you pay a premium, the insurer deposits it into its general account, a large pool of conservatively managed assets holding investment-grade corporate bonds, government securities, and commercial mortgage loans. The company then earns a return on that pool while crediting you a lower rate on your contract. The difference is the investment spread, and it is the single largest source of profit on fixed and fixed indexed annuities.
The math is simple. If the general account earns 5.5% and your contract guarantees 3.5%, the insurer keeps the remaining 2%. That margin has to cover operating costs, agent compensation, and profit. Insurers monitor interest rate conditions and adjust the rates offered on new contracts to protect it.
State insurance regulators oversee general accounts and require reserves large enough to pay every future obligation. Those rules keep insurers from chasing high yields with risky bets, which is why general account portfolios lean heavily toward bonds rather than stocks. For you, the result is predictable, modest growth backed by the insurer’s claims-paying ability. For the insurer, it’s a stable spread business.
Mortality Assumptions Do Quiet Work
Annuities can promise income you cannot outlive because the insurer pools thousands of contract holders together and applies actuarial math to predict how many will die each year. Funds left behind by participants who die earlier than average stay in the pool and subsidize payments to those who live longer than expected.
If you live to 95, that pooling works in your favor. If you die at 72, the remaining balance effectively helped fund someone else’s payments. Actuaries calculate the necessary reserves using standardized mortality tables; for contracts issued in recent years the 2012 Individual Annuity Reserving Table is the prescribed minimum standard, replacing older tables the industry relied on for over a decade. Because life expectancy keeps rising, insurers hold larger reserves today than a generation ago, and they price contracts to earn a margin above those reserve requirements.
Fees Deducted Inside the Contract
Most annuity fees are not billed to you separately. They’re pulled from your account value, so your balance simply grows more slowly than the underlying investments would suggest. Fixed annuities carry minimal explicit fees because the insurer recovers costs through the spread. Variable and indexed annuities add more layers.
Mortality and Expense Risk Charge
The mortality and expense (M&E) risk charge compensates the insurer for guaranteeing that payments continue regardless of how long you live and regardless of how the company’s actual claims experience compares to its projections. On variable annuities this charge typically runs from about 0.50% to 1.50% of account value per year. Part of it sometimes covers distribution costs, including the commission paid to the agent who sold the contract.1U.S. Securities and Exchange Commission. Variable Annuities: What You Should Know
Administrative Fees
Administrative fees cover the overhead of maintaining your contract: processing transactions, issuing statements, managing beneficiary records. They’re typically small, either a flat annual amount or roughly 0.15% to 0.30% of account value. On a $200,000 annuity that’s roughly $300 to $600 a year. Some contracts waive the flat fee once your balance passes a threshold.
Sub-Account Expenses on Variable Annuities
Variable annuities let you invest in sub-accounts that resemble mutual funds, and each carries its own internal management fees, described in the product prospectus and deducted before returns are credited to your account.1U.S. Securities and Exchange Commission. Variable Annuities: What You Should Know Stacked on top of the M&E charge and administrative fees, total annual costs on a variable annuity can exceed 2% of account value, a drag that compounds significantly over a long accumulation period.
Rider Fees
Optional riders, such as a guaranteed lifetime withdrawal benefit or an enhanced death benefit, add another annual charge, usually 0.25% to 1.00% of the contract’s benefit base. The benefit base is often calculated differently than the account value, so the dollar amount of the fee can be larger than it first appears. Riders can be valuable, and they’re also where costs quietly stack up.
Surrender Charges Pay Back the Commission
Surrender charges are the penalty you pay for withdrawing more than the allowed amount during the early years of the contract. A typical schedule starts at 7% if you cash out in the first year and drops by one percentage point annually, reaching zero after the seventh or eighth year. Most contracts let you withdraw up to 10% of your account value each year without triggering this penalty.1U.S. Securities and Exchange Commission. Variable Annuities: What You Should Know
The schedule exists because the insurer pays the selling agent a commission upfront, generally 1% to 8% of the premium. Fixed indexed and variable annuities carry the highest commissions; simple fixed and immediate annuities sit at the low end. You never see this deducted from your premium. The insurer pays the agent directly and recoups the outlay through the spread, ongoing fees, and the surrender period, which locks your money in long enough for the contract to become profitable to the company.
Some fixed annuities also apply a market value adjustment (MVA) on top of the surrender charge. The MVA links your withdrawal value to interest rate changes since purchase, calculated using a formula tied to Treasury rates, the rate locked at purchase, and the months remaining in your term. If rates have risen, the MVA reduces your payout; if rates have fallen, it can increase it. The mechanism exists because the insurer bought long-term bonds with your premium, and rising rates cut the market value of those bonds. The MVA passes part of that loss to you if you leave early.
How Indexed Contracts Keep the Upside
Fixed indexed annuities link your interest to a market index, commonly the S&P 500, while protecting principal from market losses. If the index drops 15% in a year, you earn zero for that period rather than losing money. The 0% floor is a contractual guarantee backed by nonforfeiture requirements that apply to all fixed annuities.
In exchange for that downside protection, the insurer limits your upside using three main mechanisms:2Morgan Stanley. Understanding Index Annuities
- A cap rate sets the maximum interest you can earn in a crediting period. If the cap is 6% and the index gains 10%, you receive 6%.
- A participation rate credits only a percentage of the index gain. At 90% participation, a 10% index gain produces a 9% credit.
- An index spread subtracts a flat percentage from the index gain before crediting. With a 2% spread, a 10% index gain becomes an 8% credit.
Not every contract uses all three at once, and the insurer can reset caps and participation rates annually. These limiters are how the company covers its hedging costs. It buys options on the underlying index to deliver your credited interest, and the caps and participation rates keep those hedges profitable. Two indexed annuities tracking the same index can produce very different returns depending on where these dials are set, so the disclosure statement matters more than the marketing brochure.
Tax Deferral Is Yours, Not the Insurer’s Revenue
One point worth being clear on: tax deferral is a benefit to you, not a source of income to the insurer. Earnings inside the contract grow without annual taxation, so your money compounds faster than it would in a taxable account earning the same rate. That advantage doesn’t put dollars in the insurer’s pocket; the insurer’s profit still comes from the spread, mortality assumptions, fees, surrender charges, and crediting formulas described above. The IRS separately imposes ordinary income tax on withdrawn earnings and a 10% penalty on taxable amounts pulled out before age 59½, but those are tax consequences, not costs paid to the insurance company.3Internal Revenue Service.

Putting the Pieces Together
Every annuity earns the insurance company money through some combination of the same levers. A plain fixed annuity relies almost entirely on the spread, which is why its published fees look so low. A variable annuity keeps the spread on any fixed-account allocation but leans on M&E charges, sub-account expenses, and rider fees for most of its revenue. A fixed indexed annuity uses the spread on the insurer’s bond portfolio, funds its options budget from that spread, and then keeps whatever index return exceeds the caps and participation rates. Surrender charges and commissions sit behind all three, ensuring the insurer has enough time with your money to recover what it paid the agent on day one.
When you compare contracts, look for the total drag: the spread you can infer from the credited rate versus prevailing bond yields, the explicit fees listed in the prospectus or disclosure statement, the surrender schedule, and, on indexed products, the caps, participation rates, and spreads. Those numbers together tell you what the insurer expects to earn from your contract. Whether that price is fair depends on how much you value the guarantees you’re buying in return.
