An annuity is a financial product that converts a lump sum of money into regular income payments. You can think of it as creating your own pension. You give an insurance company money today, and they commit to paying you back in regular installments later.
In essence, you're trading immediate access to a large sum for the security of predictable income over time. For many retirees, this trade-off provides peace of mind that they won't outlive their savings.
How Annuities Work
When you buy an annuity, you're entering into a contract with an insurance company. You can fund this either with a single lump sum payment or through multiple payments over time. The insurance company then invests this money and guarantees you a specific payment schedule in return.
The amount you receive depends on several key factors. Your age plays a major role — older purchasers typically receive higher monthly payments because their life expectancy is shorter. A 75-year-old might receive 30-40% more per month than a 65-year-old with the same investment amount.
Interest rates at the time of purchase matter significantly, too. When rates are higher, annuity providers can offer better payouts. This is why annuity rates were particularly attractive in 2024 and 2025, with rates reaching levels not seen in over a decade.
The type of annuity you choose also affects your payments. Lifetime annuities pay less per month than fixed-term options because the insurance company may have to pay you for decades. Additional features, such as inflation protection or survivor benefits, reduce your payment amount but provide valuable protections.
The Economics Behind Annuities
Annuities work through something called mortality credits or longevity pooling. With lifetime annuities, people who die earlier than expected effectively subsidize payments to those who live longer. This pooling of longevity risk is what allows insurance companies to offer lifetime guarantees.
Your payments come from three sources:
- the principal you invested
- interest earnings on that money
- mortality credits from the annuity pool
This combination allows annuities to often pay more than you could safely withdraw from an investment portfolio.
Insurance companies manage annuity obligations by investing in long-term bonds and other fixed-income securities. They're required by state insurance regulators to maintain significant capital reserves to ensure they can meet their payment obligations for decades.
Main Types of Annuities
Annuities come in several varieties, each suited to different needs:
Immediate annuities start paying you within a year of purchase. You hand over a lump sum and begin receiving monthly income soon after. These work well if you've just retired or need income right now.
Deferred annuities involve a waiting period before payments begin. You might buy one at 55 and set it to start paying at 70. During the deferral period, your money typically grows tax-deferred (meaning you don't pay taxes on the accumulated interest and returns until you start receiving payments). The longer you defer, the higher your eventual payments will be.
Fixed annuities provide the same payment amount every single period. If you're getting $2,000 monthly, you'll receive exactly $2,000 whether markets are up or down. This predictability is valuable for budgeting but means you'll lose purchasing power to inflation over time.
Variable annuities tie your payments to investment performance. Your money gets invested in sub-accounts similar to mutual funds, and your income fluctuates based on how those investments perform. These are complex products with high fees, and most retirees are better served by simpler options.

Who Uses Annuities and Why
People buy annuities for various reasons:
- Retirees without pensions find annuities appealing because they create pension-like income. If your only guaranteed income is Social Security and it doesn't cover your expenses, an annuity can fill that gap.
- Those worried about longevity appreciate knowing they can't outlive their money. If you have family members who lived into their 90s, a lifetime annuity provides insurance against the risk of running out of income later in retirement.
- Conservative investors who want to avoid market volatility value the stability annuities provide. Your payments arrive like clockwork regardless of what's happening in financial markets.
- Lottery winners and people receiving large settlements sometimes use annuities to ensure they don't burn through their windfall too quickly.
- Accident victims' structured settlements often involve annuities.
- Parents of children with disabilities may set up annuities to provide lifetime income for a dependent who can't manage money independently. Special needs trusts often incorporate annuities for this purpose.
The Annuity Purchase Process
Buying an annuity requires more diligence than many financial products. Start by determining how much income you'll need. Calculate your essential expenses, such as housing, food, utilities, and healthcare, and see how much your guaranteed sources (e.g., Social Security or state pension) cover. The gap is what you might fill with an annuity.
Annuity rates can vary significantly between providers for identical terms, so shopping around is important.
In the US, state guaranty associations typically protect up to $250,000 per insurer (however, limits vary by state, with some offering up to $500,000), so you might split large purchases across multiple highly-rated companies.
Similar protection schemes exist in other countries, too. Assuris in Canada protects monthly annuity payments up to $5,000/month or 90% (whichever is higher), the UK's Financial Services Compensation Scheme (FSCS) provides 100% protection with no cap for qualifying annuities, and various schemes exist across some EU member states, even though coverage varies significantly.
Before buying an annuity, check the insurance company's financial strength ratings. Only consider companies rated A+ or better by rating agencies such as AM Best, Standard & Poor's, or Moody's. Your payments are only as secure as the insurer backing them.
Always understand exactly what you're buying. Read the contract carefully or have a financial advisor review it. Pay attention to fees, surrender charges if you change your mind, and any conditions that might affect your payments.
Some jurisdictions offer a free look or cooling-off period after purchase. In the US, this typically lasts 10-30 days depending on your state, during which you can cancel without penalty and receive a full refund. Some states provide longer periods for seniors or when replacing an existing annuity. Check with your insurance regulator or department to confirm what protections apply in your jurisdiction, as these provisions vary significantly.
When Annuities Make Sense
Annuities work well in certain situations. If you're retiring without a pension and need to create guaranteed income, they serve a clear purpose. When Social Security or state pension doesn't cover your basic expenses, annuities bridge that gap reliably.
For those concerned about cognitive decline later in life, annuities remove the need to manage investments when you might not be capable of doing so effectively. The payments just keep coming automatically.
If you value peace of mind over maximizing returns, the certainty annuities provide might be worth the trade-offs since you'll know your essential expenses will be covered regardless of market conditions.
When to Avoid Annuities
Don't buy an annuity if you don't have adequate emergency savings elsewhere. Annuities are illiquid — once you buy an immediate annuity, you typically can't access the principal. Keep 6-12 months of expenses in accessible savings first.
If you're in poor health or have a family history of shorter lifespans, lifetime annuities might not pay off. You're betting on living a long time, and if you don't, the insurance company keeps what's left. Fixed-term annuities or enhanced annuities for those with health issues might be better options.
Younger investors usually have better alternatives. If you're under 55, there's typically more value in contributing to tax-advantaged retirement accounts such as 401(k)s (in the US), IRAs (in the US), SIPPs (in the UK), superannuation funds (in Australia), and others (depending on your country). These offer tax benefits with more flexibility.
If you want to leave a substantial inheritance, you should think carefully. Most annuity options don't leave much or anything for heirs. You're converting wealth into income, not preserving it for the next generation.
Annuities vs. Other Retirement Income Strategies
Annuities are just one tool in retirement planning. Many experts suggest a balanced approach.
For example, you can use some assets to buy an annuity covering essential expenses, invest other assets for growth, and keep some money liquid for emergencies and opportunities. You can read more about this approach in our three-bucket strategy guide.
Compared to a systematic withdrawal plan from investments, annuities remove longevity risk and market timing concerns but offer less flexibility and upside potential. Compared to bonds or bond ladders, annuities typically pay more for lifetime income but provide no liquidity or inheritance value.
Are Annuities Worth It for You?
Deciding whether to purchase an annuity depends on your specific situation. Consider your risk tolerance, other income sources, health status, and legacy goals. Your specific situation might vary depending on your country, as regulations and product availability differ.
Most people benefit from professional guidance when considering annuities. It's recommended that you consult a fee-only financial advisor, who can help you evaluate whether an annuity fits your retirement plan without the bias of commission-based sales.
Regulatory standards vary by country and advisor type. In some jurisdictions, certain advisors must act in your best interest (fiduciary duty), while others only need to ensure recommendations are suitable. Always ask how your advisor is compensated and what standards they're held to.
