Understanding how you can use immediate annuities to fund your retirement

There are basically three ways you can turn your retirement savings into a regular paycheck. In this post, the third of a series, I explain how immediate annuities work and the income you can expect to generate if you buy one early this year. You may also want to read the first post, on generating income from interest and dividends, as well as the second one in the series about implementing systematic withdrawals for retirement income.

First, some background on immediate annuities.

With an immediate annuity, you give your retirement savings to an insurance company and it promises to pay you monthly retirement income for the rest of your life (no matter how long you live). You can continue the income flow for your spouse or partner after you die by using a joint and survivor annuity.

The amount of income this method generates will vary depending on the type of annuity you purchase, as well as your age, sex and marital status. To provide more of an across-the-board look at this method, I've shown the results for fixed annuities, variable annuities, guaranteed lifetime withdrawal benefits (GLWB) and inflation-adjusted annuities.

  • For fixed and inflation-adjusted annuities, I used rates from Vanguard's Annuity Access service that uses the Hueler Income Solutions platform
  • For GLWB annuities, I used the payout rates under Prudential's IncomeFlex annuity that is offered in many 401(k) plans
  • I used immediate variable annuity rates offered by the mutual fund company Vanguard and American General Life Insurance, with an assumed investment return (AIR) of 3.5 percent

Below are the annual incomes generated for a single man, a single woman and a married couple at three different ages. I've used annuity purchase rates at the beginning of January, 2014, assuming you have $100,000 to buy the annuity. I've included the annual payout rates in order to compare immediate annuities to other methods of generating retirement income in my previous posts. These payout rates are not to be confused with investment rates of returns.


Compared to annuity rates offered at the beginning of July, 2013, fixed annuity rates have improved slightly but inflation-adjusted annuity rates have worsened slightly. Variable annuity rates and GLWB payout rates have remained unchanged.

If you compare the retirement income amounts generated by the three methods I've described in this and the two previous retirement income posts, you'll see a wide range of results, depending on the method you use and your individual circumstances. In particular, you'll see that immediate fixed and variable annuities usually provide a higher initial retirement paycheck than systematic withdrawals or depending only on interest and dividends.

It's particularly helpful to compare inflation-adjusted annuities with the "4 percent rule," which is an application of systematic withdrawals often recommended by financial planners. For retirements at age 65, inflation-adjusted annuities have higher payout rates for individuals than the 4 percent rule, and the payout rates for couples are just below 4 percent. The payout rates are 5.1 percent for single men, 4.7 percent for single women, and 3.9 percent for married couples. And keep in mind that the 4 percent rule has been questioned lately as possibly being too high, considering the current low interest rate environment and the significant fees for investment managers and financial advisors.

With inflation-adjusted annuities, you're guaranteed that your income lasts for the rest of your life and is adjusted for inflation, no matter how long you live and no matter what happens in the stock and bond markets. With systematic withdrawals, you hope to achieve these outcomes, but there's no guarantee, particularly if you suffer poor investment returns or live a long time.

The big tradeoff with most immediate annuities is that you generally give irrevocable control of your savings to the insurance company, while with systematic withdrawals you have the flexibility to tap into your savings. And with most annuities, there's no money left for a legacy after you and your beneficiary die; with systematic withdrawals, you can leave a legacy with any money left in your accounts when you die. Note that GLWB annuities are the exception to the above statements about annuities, and they offer the ability to tap into your savings and the potential to leave a legacy with any money left over after you die. But there's a tradeoff, since GLWB annuities have lower payout rates than fixed or variable annuities, and they incur fees for the insurance guarantees.

When it comes to generating a retirement paycheck that will last the rest of your life, there's no single answer that is appropriate for everybody. Your answer depends on your goals and circumstances. I often recommend that you split your retirement savings between annuities and systematic withdrawals, so that you diversify your retirement income and realize the advantages of each method.

Please note that the incomes shown above are pre-tax amounts. Federal and state income taxes will have a significant effect on your after-tax income and should be taken into account. The income taxes you pay will vary depending on whether your annuity was purchased with pre-tax investments in traditional IRA or 401(k) accounts, or with after-tax investments.

Because only you know which method or combination of methods might work best for you, you should take the time to learn as much as you can about the various methods of generating a retirement paycheck. You'll thank yourself when you reach your 80s and 90s and your retirement income keeps chugging along.
