How to Turn Your Retirement Savings Into Monthly Income

Saving for retirement and living off retirement savings are two completely different problems. For decades, the goal is simple: accumulate as much as possible. Then one day the paychecks stop, and the account that was only supposed to grow now has to generate spending money every month for the next 20 or 30 years.

Most people have given far more thought to the accumulation side than the distribution side. This article covers the main options for converting a lump sum into reliable monthly income, including what each one pays and where a fixed indexed annuity fits into the picture.

Key Takeaways

• The core challenge in retirement income is converting a single balance into a stream of payments that lasts as long as you do, without knowing in advance how long that will be.
• Portfolio withdrawals, immediate annuities, and deferred annuities with income riders each solve the problem differently, with different trade-offs in flexibility, payout size, and longevity protection.
• Current April 2026 annuity rates show a $300,000 immediate annuity paying roughly $1,845 to $2,280 per month for a 65-year-old, depending on payout structure and gender.

Option 1: Systematic Withdrawals from Your Portfolio

The most common approach is simply withdrawing a percentage of your investment portfolio each year. The 4% rule, developed by financial planner William Bengen in the 1990s, suggests withdrawing 4% of your portfolio in the first year of retirement and adjusting that amount for inflation each year after.

On a $500,000 portfolio, that produces $20,000 in year one, or about $1,667 per month.

The appeal is flexibility. You keep full control of the money, can adjust spending in any given year, and the remaining balance passes to your heirs.

The problem is sequence-of-returns risk. Morningstar’s 2025 research found that retirees who experienced poor market returns in the first five years of retirement and did not adjust their spending were far more likely to deplete their savings prematurely.

A bad market in year two of retirement hits differently than a bad market in year twelve, because you are selling shares at depressed prices to cover living expenses with no opportunity to let the portfolio recover undisturbed.

Morningstar researchers have also noted that some financial experts, including Wade Pfau, suggest a starting withdrawal rate closer to 3.3% to 3.7% may be more appropriate for today’s retirees given current market valuations and longer life expectancies.

At 3.5%, a $500,000 portfolio generates $17,500 per year, or under $1,500 per month. That is less than many households need.

Portfolio withdrawals work best when they cover discretionary spending rather than essential bills. Using them as your only income source puts the full burden of market volatility on your monthly cash flow.

Option 2: A Single Premium Immediate Annuity

A single premium immediate annuity (SPIA) converts a lump sum into a guaranteed monthly payment that starts within 30 days and continues for the rest of your life. You hand a sum of money to an insurance company, and they send you a check every month no matter how long you live.

The payment amount is fixed at purchase based on your age, gender, and current interest rates.

Based on April 2026 SPIA rates from Annuity.org, here is roughly what different balances generate for a 65-year-old:

Premium	Approx. Monthly Payment (Single Life, Age 65)
$100,000	$590 to $625
$200,000	$1,180 to $1,250
$300,000	$1,798 to $1,916
$500,000	$2,966 to $3,151

Men receive slightly higher payments than women because actuarial life expectancy tables run shorter for men. Adding a joint life option, which continues payments for a surviving spouse, reduces the monthly amount by roughly 10% to 15%.

The trade-off with a SPIA is irreversibility. Once you hand over the premium, you no longer own that money as a lump sum. If you need $50,000 for a medical emergency in year three, it is not available.

The payment also does not grow with inflation unless you purchase an inflation-adjustment rider at the time of purchase, which reduces the starting payment.

A SPIA is most useful for covering essential, fixed expenses: housing, utilities, food. Pair it with a separate liquid account for discretionary spending and emergencies.

Option 3: A Fixed Indexed Annuity with an Income Rider

A fixed indexed annuity (FIA) with a guaranteed lifetime withdrawal benefit (GLWB) rider takes a different approach. Instead of starting income immediately, you let the contract grow during a deferral period, then turn on guaranteed withdrawals at a time of your choosing.

During the deferral years, the contract runs two parallel values. The account value grows based on index-linked credits tied to a market index like the S&P 500, with a floor that prevents principal loss in down years.

The benefit base, a separate figure used only to calculate income, grows at a stated roll-up rate, often 6% to 8% simple interest per year, regardless of market performance.

When you activate income, the carrier applies an age-based payout percentage to the benefit base. That produces your guaranteed annual withdrawal amount. The payment continues for the rest of your life even if the account value eventually reaches zero from a combination of withdrawals and fees.

Any balance remaining in the account at death passes to your beneficiaries.

The key advantage over a SPIA: you retain access to the account value during the contract. The key advantage over pure portfolio withdrawals: the income guarantee removes longevity risk entirely.

Comparing the Three Approaches Side by Side

Approach	Income Guaranteed for Life?	Access to Principal?	Remaining Balance to Heirs?	Income Starts
Portfolio withdrawals (4% rule)	No	Yes, fully	Yes, whatever remains	Immediately
Single premium immediate annuity (SPIA)	Yes	No	Only with period certain option	Within 30 days
Fixed indexed annuity with income rider	Yes	Yes, with restrictions	Yes, remaining account value	When you choose

How to Think About Combining These Options

Most retirement income plans work better when they use more than one approach. The goal is to cover essential expenses with guaranteed sources and use flexible tools for everything else.

A straightforward structure many retirees use:

• Social Security covers a base layer of income. Delaying to age 70 increases the benefit by about 8% per year past full retirement age, a guaranteed return available from no other source.
• An annuity, whether a SPIA or an FIA with an income rider, fills the gap between Social Security and essential monthly expenses. This creates a guaranteed income floor that does not depend on market performance.
• An investment portfolio covers discretionary spending, large one-time expenses, and emergencies. Because essential bills are already covered, this money can stay invested longer without the pressure of forced withdrawals during a downturn.

Financial planner Dana Anspach of Sensible Money recommends using guaranteed income coverage as a benchmark: if your guaranteed income sources cover less than 50% of essential expenses, adding a guaranteed income product is worth serious consideration.

A Note on Taxes

The source of the money you use to purchase an annuity affects how the income is taxed. Annuity income funded with pre-tax dollars from a traditional IRA or 401(k) is taxed as ordinary income in full, dollar for dollar, as payments arrive.

Annuity income funded with after-tax dollars is taxed only on the gain portion of each payment, with the return of your original premium treated as tax-free. The IRS refers to this as the exclusion ratio. Confirm the tax treatment with a qualified tax professional before purchasing, particularly if you are rolling over a 401(k).

Turning a savings balance into monthly income is not a single decision. It is a structure built from several pieces, each covering a specific piece of the income problem. The more clearly you define what each dollar needs to do, the easier it becomes to match the right tool to the right job.
