“Is now a good time to buy an annuity?”

That’s one of the most common questions I hear from clients — and the honest answer is: it depends entirely on your age, your income timeline, and what you’re trying to accomplish.

Annuities are not one-size-fits-all products. The same contract that’s a smart move for a 65-year-old with $400,000 to protect might be the wrong choice entirely for a 45-year-old with decades of accumulation ahead. And a 75-year-old who waited “just a bit longer” may have left thousands of dollars of annual income on the table.

In this guide, I’ll walk through the annuity timeline by decade — what each age window makes sense for, the math behind deferral, and why most financial professionals consider 60–70 the sweet spot for purchasing a fixed index annuity with a guaranteed lifetime income rider.

First: Not All Annuities Are the Same

Before we talk about age, a quick clarification: “annuity” covers several very different products.

Immediate Income Annuity (SPIA): You deposit a lump sum and immediately start receiving income payments for life (or a fixed period). Best for those who need income right now.
Fixed Annuity (MYGA): Like a bank CD but issued by an insurance company — fixed interest rate, fixed term. Best for conservative savers who want guaranteed growth without income features.
Fixed Index Annuity (FIA): Growth linked to a market index (like the S&P 500) with a floor of 0% — no losses in down years. Often paired with a GLWB rider for future guaranteed income.
Variable Annuity: Growth based on sub-account investments (like mutual funds), with market risk. Higher potential upside, but real downside risk.

This article focuses primarily on Fixed Index Annuities with Guaranteed Lifetime Withdrawal Benefit (GLWB) riders, since those are the most versatile and commonly used for retirement income planning. The age guidance, however, applies broadly across product types.

The Core Math: Why Timing Matters

With income annuities, two factors drive the size of your guaranteed lifetime paycheck:

1. How large your income base is when you activate income 2. Your payout rate, which increases with age

These two factors compound in your favor when you defer — but only to a point. There’s a diminishing return to waiting past a certain age that most people don’t anticipate.

Let’s look at a simple illustration. Assume a $300,000 premium, 6% compound roll-up rate on the income base, and a carrier’s standard payout table:

Age When Income Activated	Income Base	Payout Rate	Annual Income
60 (immediate)	$300,000	4.00%	$12,000
65 (5 years deferred)	$401,469	4.75%	$19,070
70 (10 years deferred)	$537,253	5.75%	$30,892
75 (15 years deferred)	$719,075	6.50%	$46,740

The math looks extraordinary for waiting until 75. But here’s what that table doesn’t show:

You collected $0 of guaranteed income from age 60–75 while waiting
The person who activated at 65 has already collected ~$95,350 in income by age 75
The person who activated at 70 has collected ~$154,460 by age 75

Waiting longer only “wins” if you live long enough for the higher annual payment to recoup the years of foregone income. That break-even analysis changes the picture significantly.

Age by Age: What Makes Sense at Each Life Stage

Under 50: Generally Too Early for Income-Focused Annuities

If you’re in your 40s, the priority is usually growth — maximizing your retirement savings before you need income. A fixed index annuity can still make sense at this stage, but usually without a GLWB rider.

What might make sense:

A short-term MYGA (2–5 year fixed annuity) as a safe alternative to CDs or bonds
An FIA focused on accumulation, without the income rider fee dragging on growth
Deferring the GLWB rider purchase until later (some carriers allow you to add it later; others don’t)

What to avoid:

Long-term surrender periods (10+ years) that lock up money you may need for other opportunities
GLWB riders on 40-year-olds — the fees compound over too many years before you benefit

Ages 50–59: Building the Foundation

This decade is when serious retirement income planning begins. Many people at this stage start asking: “How do I make sure I don’t run out of money?”

An FIA purchased in your early to mid-50s can have a meaningful deferral period — 10–15 years — before you need income. That deferral magnifies the income base substantially.

What tends to work well at 50–59:

A multi-year MYGA for a portion of fixed-income savings while interest rates are favorable
An FIA with GLWB rider if you plan to retire at 65–70 and want 10+ years of income base growth
Conservative portfolio rebalancing — gradually shifting from pure equities into income-producing vehicles

Key consideration: At this age, you still have significant accumulation potential in equities. Most advisors suggest keeping the majority of retirement savings in growth assets at 55, with an FIA serving as the “safe floor” portion of the portfolio.

Ages 60–65: The Early Sweet Spot

This is where the math starts to really favor a fixed index annuity with a GLWB rider.

At 60–65, you’re typically 5–10 years from needing income. That’s enough deferral time for the income base to grow meaningfully, but not so far that you’re paying rider fees for decades before you benefit.

Why 60–65 often works well:

5–10 year deferral window — enough for the income base to grow 34–79% (at 6% compound)
Payout rates are competitive — at 65, most carriers offer 4.5–5.25% annual payout rates
Rider fees are contained — you’ll pay them for 5–10 years before income starts, not 20
Health is typically still good — you can pass medical underwriting if required
You can coordinate with Social Security timing — using GLWB income to bridge while you wait to claim SS at 70

The Social Security bridge strategy: For many clients I work with, buying an FIA at 62–65 and using GLWB income to replace the income they would have gotten from Social Security at 62 — while actually delaying SS until 70 — significantly increases lifetime income. As an RSSA®, I model this strategy regularly. The gains can be substantial: $50,000–$150,000+ in additional lifetime income depending on your benefit amount and life expectancy.

Ages 65–70: The Prime Window

If I had to name a single age range where fixed index annuities with GLWB riders most consistently make mathematical sense, it’s 65–70.

Here’s why this window is optimal:

Payout rates are meaningfully higher than at 60. At 65, you might get 4.75–5.25%. At 70, you’re often looking at 5.5–6.25%. Those percentages matter enormously when applied to a large income base.

Deferral still adds value. Even if you’re 67 and plan to activate income at 72, that 5-year deferral can add $60,000–$100,000+ to the income base on a $300,000 premium.

You’re close enough to need it. The time between purchase and income activation is short enough that rider fees don’t erode excessive value.

Health considerations become relevant. Waiting too long increases the chance that health events intervene — either making you want to preserve assets for care rather than lock them into income, or in some cases affecting insurability.

Illustration — FIA purchased at 67, income activated at 72:

Premium: $400,000
Income base after 5 years at 6.5% compound: ~$548,000
Payout rate at 72: 5.8%
Annual guaranteed income: ~$31,784/year
Monthly income: ~$2,649

That’s over $2,600/month in income you cannot outlive — in addition to Social Security.

Ages 70–75: Still Viable, But Nuances Increase

Buying an FIA in your early 70s is still a reasonable option — but the math and the priorities shift.

At 70+, immediate income often makes more sense than a GLWB rider with a long deferral period. If you need income now, a Simplified Income Annuity (SPIA) might provide more income per dollar than an FIA you’d defer for years.

That said, there are situations where an FIA with a short 3–5 year deferral still makes sense at 72–74:

You have a pension or other income covering immediate needs but want a larger income in 3–4 years
You want market participation with a floor, plus a future income guarantee
You want the death benefit structure an FIA provides (passing remaining account value to heirs)

The key shift at 70+: More of your planning energy should go toward immediate income optimization (Social Security, RMDs, pension maximization) and less toward long-term deferral strategies.

Age 75+: Immediate Income Often Wins

At 75 and beyond, the dynamics favor immediate income solutions. If you need guaranteed income today, a Single Premium Immediate Annuity (SPIA) typically provides more income per dollar at these ages than an FIA with a GLWB rider because:

SPIA payout rates are exceptionally high at older ages
You no longer have time for meaningful income base roll-up
The administrative simplicity of a SPIA reduces oversight burden

FIAs at 75+ can still serve as accumulation vehicles (protecting assets, capturing index-linked growth), but the GLWB rider is less compelling when deferral time is short.

The “Waiting Too Long” Problem Most People Don’t Anticipate

Here’s something counterintuitive: waiting longer than 70–72 to buy an FIA with a GLWB rider often produces worse outcomes than buying at 67–70 and deferring.

Why? Several reasons:

1. You forgo years of income base accumulation inside the contract. If you buy at 67 and defer to 72, your income base grows for 5 years. If you wait to buy at 72, you’re starting fresh — no accumulated income base.

2. Premium is the same, but starting value is lower. The income base at purchase is your premium. Whether you buy at 67 or 72, you start at the same number. But the person who bought at 67 and deferred has been rolling up for 5 years.

3. Surrender periods. Most FIAs have 5–10 year surrender periods. Buying at 72 means potential surrender charges if you need the money in your late 70s.

4. Health changes can affect planning options. While FIAs don’t require medical underwriting, other retirement income solutions (like long-term care hybrids) do. Waiting too long can eliminate certain options.

What To Do Right Now (At Any Age)

The best time to do an annuity analysis is before you need one — when you have time to compare carriers, optimize the income base growth period, and coordinate with Social Security timing.

If you’re 55–60: Model the income base growth at a 10-year deferral. Understand what your guaranteed income could look like at 70 and what percentage of your income needs it would cover.

If you’re 60–65: Seriously evaluate whether a portion of your safe-money assets belong in an FIA with a GLWB rider. Run the Social Security bridge math.

If you’re 65–70: This is prime time. Get at least 3–4 carrier illustrations and compare income base growth, payout rates, rider fees, and death benefit options. Don’t buy the first one you’re shown.

If you’re 70–75: Evaluate whether immediate income (SPIA) or deferred income (FIA) better fits your timeline. Model both.

At any age: Never buy an annuity you don’t fully understand. If an advisor can’t explain in plain English exactly how the income base grows, how the payout rate is calculated, and what the rider fee costs you annually — that’s a red flag.

The Bottom Line

The best age to buy a fixed index annuity is typically somewhere between 60 and 70 — with the sweet spot in the 65–70 range for most retirees. Early enough to benefit from income base deferral. Late enough that payout rates are competitive.

But “best” is personal. Your Social Security age, pension income, spending needs, health, and legacy goals all affect the optimal timing.

That’s why an individualized analysis beats any general rule of thumb.
