Understanding how insurance companies invest your annuity funds to provide growth, safety, and lifetime income.
When you buy an annuity, your money doesn’t just sit idle—the insurance company invests it to generate the returns that fund your contract. But what exactly do annuity companies invest in? The answer depends on the type of annuity and the company’s financial strategy. Most annuity providers invest heavily in conservative, long-term assets like bonds, mortgages, and government securities to keep your principal safe and provide steady income. Others may use equities or alternative investments when offering variable or indexed products. Understanding where your money goes helps you see how annuities remain stable, why returns differ, and what risks are involved. While this guide focuses specifically on investment portfolios, it is important to remember that the broader life insurance company profit model also relies on mortality credits and lapsing policies to maintain financial strength.
Fixed Annuities
For traditional fixed annuities, the company that sells you the annuity will invest all of the money it receives from you in traditional investments, like corporate bonds, mortgage-backed securities, and similar investments.
The contract owner gets most of the profit yield. The rest goes toward acquisition, maintenance costs, and a profit for taking risks.

Fixed Index Annuities
To provide for market-linked growth and principal protection, the insurance company uses a small percentage of the contract owner’s premium to buy a call option from a group of investment banks. As a result, the best call option price is the one that gives the contract owner the highest cap for the fee the insurance company pays.
When the market rises, the insurance company pays the contract owner 100% of the return from the expiring call option. The insurance company does not deduct fees for the option’s cost or the competitive bidding process.
When the market declines, the call option expires and is worthless. This outcome means that the insurance company still pays for the option.

How Annuity Companies Make Money
1. Interest Rate Spread (The Investment Margin Game)
Annuity companies primarily profit from the difference between what they earn on your premium and what they credit to your account. This revenue driver is known as the spread or investment margin.
- For example: If they earn 6% investing your funds and credit you 4%, they keep 2% as profit.
- This model applies to fixed annuities, fixed indexed annuities (FIAs), and MYGAs.
Why it works: Insurers are expert bond investors and manage large-scale portfolios at lower cost. They can take a long-term view and lock in yields with less risk than individuals can.
Who benefits: You get principal protection, and the insurer gets predictable profit.
Note: The more guarantees you receive, the lower your credited interest—because the insurer takes on more risk.
2. Fees (Rider Fees, Admin Fees, M&E Fees)
Many annuities include optional or embedded features that charge fees.
Common Fee Types:
- GLWB Rider Fees: Income guarantees for life, typically 0.95%–1.50% of the income base annually.
- M&E Fees (Variable Annuities): Mortality & expense risk charges to maintain reserves, often 1.25%–1.65%.
- Fund Management Fees: In variable annuities, the subaccounts charge fees like mutual funds (0.5%–1.5%).
- Administrative Fees: Some annuities charge flat-dollar or percentage-based admin fees annually.
Who needs fee-based features: People looking for lifetime income, market growth with downside protection, or enhanced death benefits.
Who doesn’t need them: People solely seeking accumulation with liquidity or investors averse to ongoing charges.
3. Surrender Charges (Liquidity Penalties)
Surrender charges are a mechanism by which insurers protect themselves from early withdrawals that disrupt their investment horizon.
- Typically 5–14 years: If you take out more than the free withdrawal (usually 10% per year), you’ll pay a declining penalty.
- Covers agent commissions, underwriting costs, and helps stabilize the insurer’s investment plan.
Alternative strategy: Choose annuities with shorter surrender schedules or liquidity riders if you anticipate needing access to your money.
Important Tip: Surrender charges apply to the contract value, not the income base in GLWB products.
4. Mortality Pooling and Risk Hedging
Annuities are insurance products. The concept of risk pooling allows insurers to pay lifetime income to those who live long by using funds from those who pass away earlier.
- In GLWB or annuitization: The insurer is betting on actuarial averages. Some people outlive their account value; others don’t.
- The “bet”: You may outlive your principal, but many won’t, and the company makes money from those who don’t use all the benefits.
Why this matters: You’re buying longevity insurance. The longer you live, the better the value you get—but the insurer manages the risk over a large group.
5. Unused Contract Value
In annuitized contracts, if the annuitant dies early without a refund option, the insurer keeps the remaining balance. These excess funds offset other liabilities and add to profits.
- This con is why many people opt for “period certain“ or “refund annuities”—to leave something behind.
- GLWB annuities usually allow the remaining account value to go to beneficiaries until it hits zero.
Where Does Annuity Income Come From?
The income from an annuity can come from three different sources. While you can run an interactive annuity calculator payout simulation to estimate your personal distributions, an insurance company establishes and sustains those actual payouts from three structural cash flow pools:
- The first is the investment income that the company earns on its portfolio. This return includes interest, dividends, and capital gains.
- The second source is the premium that the contract owner pays. This money goes into a separate account for expenses like acquisition and administration fees.
- The third source of income is the death benefit. If the contract owner dies, the beneficiary will receive a death benefit equal to the account value.
