Annuities are financial contracts between you and an insurance company, designed to provide a steady income stream, typically during retirement. In exchange for a lump-sum payment or a series of payments, the insurer agrees to make periodic payments to you, either immediately or at a future date. This article explains how annuities work, the common types, their costs, and how to evaluate if one fits your financial plan.

How Annuities Work: The Basics

At its core, an annuity is a long-term investment product that grows tax-deferred until you begin receiving payments. You purchase the annuity with a premium, which can be a single lump sum or multiple contributions over time. The insurer then invests that money. The growth is not taxed until you withdraw it, which can be a significant advantage for retirement savings.

The key phases of an annuity are the accumulation phase (when you contribute and the value grows) and the annuitization phase (when you start receiving regular payments). The payment amount depends on factors like the principal amount, your age, the interest rate environment, and the type of annuity you choose. For example, a typical fixed annuity might offer a guaranteed interest rate of around 3% to 5% per year, while a variable annuity’s returns depend on the performance of underlying investments, often mutual funds.

Main Types of Annuities

Fixed Annuities

Fixed annuities provide a guaranteed minimum interest rate for a set period, often 3 to 10 years. The insurer promises a specific return, so your principal is safe. For instance, a $100,000 fixed annuity might guarantee a 4% annual return for five years, ensuring you receive $120,000 at the end of the term (minus fees). These are popular for conservative investors who want predictable growth.

Variable Annuities

Variable annuities allow you to invest in sub-accounts (similar to mutual funds). Your returns fluctuate based on market performance. While they offer higher growth potential, they also carry market risk. For example, if you invest in a stock-market sub-account that loses 10% in a year, your annuity value drops accordingly. Most variable annuities include a death benefit that guarantees your beneficiaries receive at least your initial investment, minus withdrawals.

Indexed Annuities

Indexed annuities (or fixed-indexed annuities) link your returns to a stock-market index, like the S&P 500. They typically offer a cap on gains (e.g., 6% per year) and protect against losses (e.g., 0% floor). If the index rises 10% in a year, you might earn only the 6% cap. If it falls 10%, you lose nothing. This hybrid approach appeals to investors seeking moderate risk.

Immediate vs. Deferred Annuities

An immediate annuity begins payments within a year of purchase. For example, a 65-year-old with $200,000 might receive about $1,200 per month for life. Deferred annuities delay payments until a future date, allowing the money to grow tax-deferred. These are often used to accumulate savings for retirement.

Key Costs and Fees to Watch For

Annuities come with several fees that can reduce returns. Common charges include:

  • Surrender charges: A penalty for withdrawing money early, often 7% to 10% of the amount in the first year, decreasing over time. These can last 5 to 10 years.
  • Mortality and expense (M&E) fees: Typically 1% to 1.5% of the account value annually, covering insurance guarantees.
  • Administrative fees: Flat annual fees of $25 to $50 or a percentage of assets (0.1% to 0.3%).
  • Investment management fees: For variable annuities, sub-account fees range from 0.5% to 2% per year.
  • Rider fees: Optional add-ons (like guaranteed lifetime income) can cost 0.25% to 1% extra annually.

For example, a variable annuity with a 1.5% M&E fee, 0.3% admin fee, and 1% investment fee would have total annual costs around 2.8%. Over 20 years, that can significantly erode growth compared to a low-cost index fund.

Tax Treatment of Annuities

Annuities offer tax-deferred growth, meaning you pay no taxes on earnings until you withdraw them. Withdrawals are taxed as ordinary income (not capital gains), which can be a disadvantage if you’re in a high tax bracket. If you withdraw before age 59½, you typically incur a 10% IRS penalty on earnings, in addition to income tax.

For example, if you have a $100,000 annuity that grows to $150,000, and you withdraw $20,000 at age 55, the IRS treats a portion as earnings (pro-rated). You’d owe income tax on the earnings portion plus a 10% penalty. This makes annuities best suited for long-term retirement savings.

How to Evaluate if an Annuity Is Right for You

Annuities are not for everyone. They work well for individuals who want guaranteed lifetime income, have maxed out other tax-advantaged accounts (like 401(k)s and IRAs), and are comfortable with fees and illiquidity. Here are practical considerations:

  • Your risk tolerance: Fixed annuities suit conservative investors; variable annuities suit those with higher risk tolerance.
  • Your time horizon: Deferred annuities require a long-term commitment (at least 5–10 years) to avoid surrender charges.
  • Alternative options: Compare annuities to other income sources like Social Security (which is inflation-adjusted) or a bond ladder. A typical Social Security benefit for a 65-year-old in 2025 is about $1,900 per month, while a $200,000 immediate annuity might pay $1,200 per month—but Social Security has cost-of-living adjustments.
  • Inflation risk: Fixed payments lose purchasing power over time. Consider an inflation-adjusted rider (which reduces initial payments but increases them annually, often by 2% to 3%).

For example, a 70-year-old with $500,000 in savings might allocate $200,000 to an immediate fixed annuity to cover basic expenses, keeping the rest in stocks and bonds for growth and liquidity.

Frequently Asked Questions

Can I lose money in an annuity?

Yes, with variable annuities you can lose principal if your investments perform poorly. Fixed and indexed annuities typically protect principal, but early withdrawals can trigger surrender charges that reduce your balance.

What happens to my annuity when I die?

If you choose a life-only payout, payments stop at death, and the insurer keeps remaining funds. Most annuities offer death benefit riders (e.g., return of premium) that pay your beneficiaries the remaining value, often at an extra cost.

Are annuity fees tax-deductible?

No, annuity fees are not tax-deductible. They are considered part of the cost of the contract and reduce your taxable gains when you withdraw.

Annuities can be a valuable tool for generating guaranteed retirement income, but they come with complexity, fees, and long-term commitments. Before purchasing, compare quotes from multiple insurers, read the fine print on surrender periods and riders, and consider consulting a fee-only financial advisor who does not earn commissions from annuity sales. For most people, annuities work best as a small portion of a diversified retirement portfolio, not as a primary investment.
