How to Decide Whether an Annuity Fits Your Retirement Plan

An annuity is not the right choice for everyone, and the decision depends on your income needs, how much you have saved, and what you want to leave behind

Whether to buy an annuity is a personal decision based on your specific situation, not a one-size-fits-all answer. An annuity converts a lump sum of money into regular payments for life or a set period. The trade-off is that you give up control of that money in exchange for predictable income you cannot outlive. Some people need that certainty; others have enough from Social Security and pensions, or they want to keep their savings flexible.

The core question is whether you value may provide income more than you value flexibility and growth potential. If you are comfortable with market risk and want to leave money to heirs, an annuity may not suit you. If you are worried about running out of money in your 90s and have no pension, an annuity can solve that specific problem.

Key Takeaways

• An annuity makes sense if you have a gap between your may provide income (Social Security, pension) and your actual spending, and you want that gap filled predictably.
• Annuities lock up your money, so you should only buy one with funds you do not expect to need for emergencies or major expenses in the next 5 to 10 years.
• The cost of an annuity — the fees, the insurance markup, and the loss of growth potential — is real, and you should compare the monthly payment you would receive against what you could generate by investing the same amount yourself.
• Your age, health, and family longevity matter: annuities pay out over decades, so the longer you live, the better the deal becomes for you.
• A partial annuity (buying one with some of your savings, not all) is common and lets you keep some money flexible while locking in income for essentials.

When an annuity solves a real problem

An annuity works best when you have identified a specific shortfall. For example: your Social Security and pension add up to $2,500 a month, but you spend $3,500. That $1,000 gap is what an annuity could fill. You know the exact amount you need, you know it will not change, and you want certainty that the money will be there every month for the rest of your life.

This is different from buying an annuity because you are worried about the stock market or because a salesperson told you it is a safe investment. Those are emotional reasons, not structural ones. The structural reason is: you have a gap between may provide income and actual expenses, and you want to close it.

An annuity also makes sense if you have no pension and no heirs you care about leaving money to. In that case, you are not giving up anything by locking the money away — you are converting it into something you cannot outlive, which is the whole point.

The real costs of buying an annuity

When you buy an annuity, you pay three costs that reduce what you actually receive. First, the insurance company builds in a profit margin — they are betting you will live a certain number of years, and they keep the difference if you live less. Second, you pay fees, which vary by annuity type but typically range from 0.5% to 3% of your balance per year. Third, you lose the opportunity to invest the money and watch it grow.

To understand the real cost, compare the monthly payment the insurance company offers you against what you could generate yourself. If you have $100,000 and an insurance company offers you $450 a month for life, calculate what you would need to earn on that $100,000 to generate $450 a month yourself. That is roughly 5.4% per year. If you believe you can earn more than that in a diversified portfolio over your lifetime, the annuity is expensive. If you believe you cannot, or if you are too anxious to try, the annuity may be worth the cost.

This comparison is not about whether the stock market will go up or down next year. It is about your long-term return expectations and your emotional ability to stick with an investment plan when markets fall.

How your age and health change the math

An annuity is a better deal the longer you live. If you buy an annuity at 65 and live to 95, you collect payments for 30 years. If you live to 80, you collect for 15 years. The insurance company prices the annuity assuming an average lifespan for your age and gender, so if you expect to live longer than average, an annuity favors you. If you expect to live shorter than average, it does not.

Your health matters directly. If you have a serious diagnosis that shortens your expected lifespan, an annuity is a poor deal because you will not collect enough payments to recover what you paid. If you come from a family with a history of longevity and you are in good health, an annuity becomes more attractive.

Your age at purchase also affects the monthly payment. The older you are when you buy, the higher your monthly payment, because the insurance company expects to pay you for fewer years. Someone buying at 75 receives more per month than someone buying at 65 with the same amount of money.

when ready annuities versus deferred annuities

An when ready annuity starts paying you within a few months of purchase. You give the insurance company a lump sum, and they begin sending you monthly checks right away. This is straightforward: you know exactly what you are getting, and there are no moving parts.

A deferred annuity is more complex. You give the insurance company money now, it sits and grows (either at a fixed rate or tied to the stock market), and you do not take payments until later — sometimes years later. Deferred annuities often come with riders (add-ons) that let you withdraw money early, adjust payments, or leave money to heirs. These riders add cost and complexity.

For most people deciding whether to buy an annuity, an when ready annuity is simpler to evaluate. You can see exactly what you will receive and compare it directly to other uses of that money. Deferred annuities require you to forecast growth rates and understand multiple features, which makes the decision harder.

Why flexibility matters more than you might think

Once you buy an annuity, that money is gone. You cannot access it if you have a medical emergency, need a new roof, or want to help a grandchild. Some annuities let you withdraw a small percentage each year, but most do not. If you are young or you have unpredictable expenses, this is a serious constraint.

A common mistake is buying an annuity with money you might need. If you have $200,000 in savings and you spend $30,000 a year, you have roughly seven years of expenses covered. Locking all of that into an annuity leaves you with no cushion. A better approach is to keep one to two years of expenses in a savings account or money market fund, invest the rest for growth, and only buy an annuity with money beyond that cushion.

This is why partial annuities are popular. You might buy an annuity with $100,000 to cover your essential expenses, and keep $100,000 invested for flexibility and growth. That way, you get the certainty you want without giving up all control.

What to compare before deciding

If you are seriously considering an annuity, gather quotes from at least three insurance companies. The monthly payment varies based on current interest rates, the company's assumptions about your lifespan, and their profit margin. A difference of 10% to 15% between quotes is common.

For each quote, ask for the payout rate — the percentage of your initial investment you will receive per year. A $100,000 annuity paying $450 a month is a 5.4% payout rate. Compare this to what you could earn investing the money yourself, accounting for taxes. If you are in a high tax bracket, the tax-deferred growth inside an annuity may be valuable. If you are in a low bracket, it matters less.

Also ask about the insurance company's financial strength. Annuity payments are backed by the insurance company, not by the government. Check ratings from agencies like A.M. Best or Moody's to confirm the company is stable.

Frequently Asked Questions

What happens to my annuity money if I die early?

With a straight life annuity, the insurance company keeps any remaining balance. With a period-certain annuity, payments continue to your heirs for the may provide period (usually 10 or 20 years). With a joint-and-survivor annuity, your spouse continues receiving payments after you die. Each option reduces your monthly payment because the insurance company expects to pay out more total money.

Can I change my mind after buying an annuity?

Most annuities have a surrender period, usually 5 to 10 years, during which you can withdraw your money but pay a penalty — often 5% to 10% of the balance. After the surrender period ends, you can usually withdraw without penalty, but you lose the may provide income stream. Some annuities have no surrender period but charge higher fees instead.

Is an annuity better than just investing the money myself?

That depends on whether you can earn more than the annuity's payout rate and whether you can stick with an investment plan during market downturns. If you believe you can earn 6% or more long-term and you are comfortable with volatility, investing yourself may be better. If you need certainty and you are anxious about markets, the annuity's cost may be worth the peace of mind.

Do I have to buy an annuity with retirement account money?

No. You can buy an annuity with money from a traditional IRA, Roth IRA, 401(k), or taxable savings account. The tax treatment differs: annuities inside retirement accounts grow tax-deferred, while annuities in taxable accounts are taxed on the interest portion of each payment. Consult a tax professional before deciding where to buy.

What if I need the money before I planned to retire?

If you buy an annuity and then face a job loss or major expense, you are stuck. You can withdraw during the surrender period, but you will pay a penalty. This is why annuities should only be part of your retirement plan, not all of it. Keep enough liquid savings outside an annuity to cover emergencies.
