The Four Main Types of Annuities and How They Work

Fixed, Variable, Indexed, and when ready Annuities: What Sets Them Apart

An annuity is a contract with an insurance company where you give them money now and they pay you back over time. The type you choose depends on how much risk you want to take, when you need the money to start, and whether you want payments that stay the same or change with market performance.

There are four main categories: fixed annuities (may provide payments), variable annuities (payments tied to investment performance), indexed annuities (payments tied to a market index with a floor), and when ready annuities (payments start right away). Within each category, you can choose when payments begin and how long they last.

Key Takeaways

• Fixed annuities pay you a set amount each month or year, no matter what happens in the market, but the payment does not keep up with inflation.
• Variable annuities let you choose how your money is invested, so your payment amount changes based on how those investments perform.
• Indexed annuities tie your returns to a stock market index like the S&P 500, with a may provide minimum return if the market drops.
• when ready annuities start paying you within a year of purchase, while deferred annuities let you wait years before payments begin.
• Each type has different fees, tax treatment, and rules about when you can access your money without penalty.

Fixed Annuities: Predictable Payments You Can Count On

A fixed annuity pays you the same amount at regular intervals — usually monthly or annually — for a period you choose when you buy it. The insurance company guarantees this payment no matter what happens in the economy or stock market. If you buy a fixed annuity for $100,000, the company might promise to pay you $500 per month for 20 years, and that $500 does not change.

The tradeoff is that your payment is locked in when you purchase the contract. If inflation rises and your $500 monthly payment buys less groceries five years from now, the payment stays $500. You also earn no growth on your money — once you hand it over, you are receiving only what was promised, not a share of any investment gains.

Fixed annuities appeal to people who value certainty and do not want to monitor investments. They are common for people who have just retired and want to replace a paycheck with a may provide income stream. The insurance company takes the investment risk, which is why they can make that may provide.

Variable Annuities: Your Payment Rises and Falls With Your Investments

A variable annuity lets you direct your money into investment accounts — usually mutual funds — and your payment amount changes based on how those investments perform. If your investments gain 10 percent in a year, your payment goes up. If they lose 5 percent, your payment goes down. You choose which funds to invest in, and you bear the investment risk.

Variable annuities often come with a may provide minimum income benefit (GMIB), which promises a floor payment even if your investments tank. For example, you might be may provide at least $400 per month even if your account value drops. This may provide costs extra in fees, but it caps your downside risk.

Variable annuities are more complex than fixed ones because you must make investment choices and monitor them over time. They also carry higher fees — typically 1 to 3 percent per year in addition to the fees of the underlying mutual funds. They work best for people who understand investing, want growth potential, and can tolerate payment fluctuations.

Indexed Annuities: Market Upside With a Safety Net

An indexed annuity ties your returns to a stock market index — most commonly the S&P 500 — but with a may provide minimum return if the market drops. If the S&P 500 rises 12 percent in a year, your annuity might credit you with 8 percent (the insurance company takes a cut). If the S&P 500 falls 10 percent, your account might be credited with 0 percent instead of a loss.

This structure appeals to people who want market growth but fear losing money in a downturn. You get some of the upside without the full downside. However, the insurance company limits how much of the index gain you actually receive — this is called the participation rate. A 70 percent participation rate means if the index gains 10 percent, you get 7 percent.

Indexed annuities also have a cap — a maximum return you can earn in any year, often 5 to 8 percent. So even if the S&P 500 jumps 20 percent, you might be capped at 6 percent. These limits are how the insurance company manages the cost of the may provide. Fees are typically lower than variable annuities but higher than fixed ones.

when ready Annuities: Payments Start Within a Year

An when ready annuity is defined by timing, not investment type. You hand over a lump sum and the insurance company begins paying you within 12 months — often within 30 days. Most when ready annuities are fixed (you get a set payment), but you can also buy an when ready variable annuity if you want payments tied to investments.

when ready annuities are common for people who have just retired and have a large sum of money — from a pension lump-sum payout, an inheritance, or a 401(k) rollover — and want to turn it into income right away. A 65-year-old who buys a $200,000 when ready annuity might receive $1,000 per month for life.

The payment amount depends on your age, gender (in most states), the amount you invest, and how long you want payments to last. Older buyers receive higher monthly payments because the insurance company expects to pay them for fewer years. when ready annuities have lower fees than deferred annuities because the insurance company is not managing your money for years before payments begin.

Deferred Annuities: Waiting Years Before Payments Start

A deferred annuity is one where you invest money now but do not receive payments until years or decades later. You might buy a deferred annuity at age 50 and not receive payments until age 70. During the waiting period, your money grows — either at a fixed rate, through investments you choose, or tied to a market index, depending on the type.

Deferred annuities are often used as retirement savings vehicles. You contribute money over time (or in a lump sum), it grows tax-deferred inside the contract, and then you convert it to income payments later. The longer you wait to start payments, the larger each payment will be, because your account has had more time to grow.

Deferred annuities typically charge higher fees than when ready annuities because the insurance company manages your money for a longer period. They also often include surrender charges — penalties if you withdraw money before a certain date, often 5 to 10 years after purchase. These charges can be steep, sometimes 5 to 10 percent of your withdrawal.

How Payment Duration Affects Your Choice

Beyond the four main types, you also choose how long you want to receive payments. A life annuity pays you for as long as you live, no matter how long that is. If you live to 100, you keep receiving payments. If you die at 75, payments stop. Life annuities offer the highest monthly payment because the insurance company is betting you will not live extremely long.

A period-certain annuity pays for a fixed number of years — say, 20 years — whether you live or die. If you die after 10 years, your beneficiary receives the remaining 10 years of payments. If you live past 20 years, payments stop. Period-certain annuities pay less per month than life annuities because the insurance company's risk is limited to a known timeframe.

A life with period-certain annuity combines both: you receive payments for life, but if you die before the period ends (say, 10 years), your beneficiary receives the remaining payments. This option costs more than a straight life annuity but gives your heirs some protection.

Frequently Asked Questions

Can I switch from one annuity type to another after I buy it?

Most annuity contracts do not allow you to switch types once purchased. However, you can sometimes exchange one annuity for another through a 1035 exchange, which is a tax-free swap allowed by the IRS. This process involves paperwork and may trigger surrender charges if you are still in the surrender period. Speak with the insurance company or a tax professional before attempting an exchange.

Which annuity type is best for inflation protection?

None of the four main types automatically adjust for inflation, but some contracts offer an inflation rider — an add-on that increases your payment by a set percentage each year, usually 2 or 3 percent. This rider costs extra in fees but protects your purchasing power over time. Variable and indexed annuities can also provide inflation protection indirectly if your investments or index gains outpace inflation.

What happens to my annuity if the insurance company fails?

Each state has a guaranty fund that protects annuity holders if an insurance company becomes insolvent. Coverage limits vary by state but typically range from $100,000 to $500,000 per person per company. This protection covers the payment obligations, not investment losses. Before buying an annuity, you can check the financial strength rating of the insurance company through agencies like A.M. Best or Moody's.

Do I have to pay taxes on annuity payments?

Tax treatment depends on whether you bought the annuity with pre-tax money (like a 401(k) rollover) or after-tax money. If pre-tax, the entire payment is taxable income. If after-tax, only the earnings portion is taxable; the portion that represents your original contribution is not. The insurance company will send you a 1099-R form each year showing how much of your payment is taxable.

Can I access my money early if I need it?

Most annuities allow you to withdraw money, but deferred annuities often charge surrender fees if you withdraw during the surrender period — typically 5 to 10 years. These fees can be 5 to 10 percent of the withdrawal. After the surrender period ends, you can usually withdraw without penalty, though you will owe income tax on any earnings. Some annuities allow a small annual withdrawal (often 10 percent) without penalty.
