2026 SPIA Payout Rates By Age — Real Market Quotes

Annuity payouts increase dramatically with age because the insurance company expects to pay you for fewer years. Each year you wait between 65 and 75 raises your payout by ~3-5% on the same premium. This is the "deferral premium" — and it's why DIAs (Deferred Income Annuities) and QLACs are so attractive.

AgeMale — Monthly per $100KFemale — Monthly per $100KAnnual Payout %
55$500$475M=6.0% / F=5.7%
60$550$517M=6.6% / F=6.2%
65$625$590M=7.5% / F=7.08%
70$716$670M=8.6% / F=8.04%
75$850$783M=10.2% / F=9.4%
80$1,033$933M=12.4% / F=11.2%
The "wait 5 years" arithmetic:
  • $500K SPIA at age 65 (life-only, male): $3,125/mo = $37,500/yr
  • $500K + 5 years growth at 5% = $638K, then SPIA at 70: $4,572/mo = $54,866/yr
  • Waiting 5 years = 46% MORE income. The combination of longer growth on premium + higher payout factors at older age compounds dramatically.

Why women's payouts are lower

Women statistically live longer than men — about 2-3 years longer at age 65. Insurers use sex-distinct mortality tables for individual annuities (allowed by federal law for non-employer products), so a 65-year-old woman gets ~5-6% less monthly income than a 65-year-old man on the same premium. For employer-sponsored qualified plans (401(k), etc.), unisex tables are required by the Norris decision (1983) and ERISA — so qualified annuities use unisex rates that fall between male and female single-life rates.

Real April 2026 SPIA quotes per ImmediateAnnuities.com survey across 12+ carriers. Sex-distinct rates per state insurance regulations. Unisex requirements for qualified plans per Arizona Governing Committee v. Norris, 463 U.S. 1073 (1983) and ERISA §205.

Payout Options Compared — Trading Income for Protection

Every payout option except "life only" reduces your monthly income. The reduction is the price of protection — protection for your beneficiaries, your spouse, or against early death. Pick the option that matches what you're actually trying to protect against.

Option (65M $100K base)Monthly IncomeReductionBest For
Life only$625/mo0% (baseline)Single retiree, no heirs to protect, want max income
10-year period certain$608/mo-3%Want some heir protection if early death
20-year period certain$575/mo-8%Strong heir protection, accept lower income
Cash refund$590/mo-6%Heirs get any unpaid principal at death
Installment refund$600/mo-4%Same as cash refund but in installments
Joint & 50% survivor (spouse 65F)$555/mo-11%Lower income now, 50% to spouse for life
Joint & 100% survivor$540/mo-14%Spouse gets your full payment for life
Life + 3% COLA$475/mo (growing)-24%Inflation protection, but 8-12 year breakeven
The "period certain" trap: Many buyers default to 10-year period certain "just in case." But the reduction is permanent. If you live 30 years, you've paid 3% extra forever — for protection you only needed in years 1-10. Period certain only makes sense if your primary goal is heir protection. If you're married, joint & survivor is usually better than period certain because it provides protection for life of spouse, not just a 10-20 year window.

Decision tree for payout option

  • Married → Joint & Survivor (50%, 75%, or 100%). Higher survivor % = lower starting income. Pick based on how dependent spouse is on this income.
  • Single, no heirs → Life only. Maximum income; no need to protect anyone.
  • Single, want to leave money to heirs → Cash refund OR life + 20-year period certain. Cash refund typically simpler.
  • Concerned about inflation → Life + 3% COLA. But understand the 20-30% starting reduction; takes 8-12 years to break even.

Payout option mathematics per actuarial standard practice. State insurance regulations govern available options. Period certain reductions vary slightly by carrier — these are mid-market estimates.

Joint Life Annuity — Math For Married Couples

A joint life annuity pays as long as EITHER spouse is alive. Because two lives last longer than one (statistically), the insurer must pay for more years — so the monthly amount is lower than single life. The 50%/75%/100% suffix indicates what fraction of the original payment continues after the FIRST spouse dies.

Option ($100K, both age 65)Both AliveAfter First DeathTotal Reduction vs Single Life
Single life (65M only)$625/mo$0 (annuity ends)Baseline
Joint & 50% survivor$555/mo$278/mo (50%)-11%
Joint & 75% survivor$540/mo$405/mo (75%)-14%
Joint & 100% survivor$530/mo$530/mo (100%)-15%
The expected lifetime payment math is striking: For a couple both aged 65, there's a ~50% probability that at least one spouse lives to age 92 (per SOA 2025 mortality). That's 27 years of payments. A single-life annuity ending at age 82 (typical male LE) pays for 17 years. Joint life often ends up paying MORE total dollars than single life, despite the lower monthly amount, because of the longer payment period. For couples, joint life is often the financially correct choice — not just the safer one.

When to choose 50% vs 75% vs 100% survivor

  • 50% survivor: Surviving spouse's expenses drop ~30-40% (no longer cooking for two, fewer bills, etc.). Combined with their own SS + savings, 50% may be enough.
  • 75% survivor: Best balance for most couples. Surviving spouse's expenses are typically 60-75% of couple expenses, so 75% income matches well.
  • 100% survivor: Use when surviving spouse has minimal other income / savings, or when one spouse has much higher income/assets and wants strong protection for the other.

"Gender of annuitant" tactic

For a married couple, you can sometimes get higher payouts by structuring the annuity around the older spouse / younger spouse strategically. Using the older spouse as primary annuitant on joint life often yields slightly higher payouts than using the younger spouse — because the insurer's joint life expectancy formula is closer to the older spouse's mortality. Get quotes both ways.

Joint life expectancy probabilities per Society of Actuaries 2025 Mortality Improvement Scale. Survivor percentage selection guidance per Wade Pfau, Michael Kitces. Carrier-specific joint annuity quotes vary 5-10% — shop multiple.

Tax Exclusion Ratio — How Much Of Each Payment Is Tax-Free?

For non-qualified annuities (purchased with after-tax money), the IRS lets you "recover" your principal tax-free over your IRS-defined life expectancy. The portion that's tax-free is calculated via the exclusion ratio. After you've recovered all your principal, subsequent payments become 100% taxable.

The exclusion ratio formula:

Exclusion ratio = Premium / (Monthly Payment × 12 × IRS Life Expectancy)

Example for $100K SPIA at age 65M ($625/mo):

IRS life expectancy at 65: 17 years (per IRS Pub 575 Table V, Treasury Reg §1.72)

Total expected payments = $625 × 12 × 17 = $127,500

Exclusion ratio = $100,000 / $127,500 = 78.4%

Tax-free portion of each payment = $625 × 78.4% = $490

Taxable portion = $625 - $490 = $135

Buyer Profile (non-qualified)Exclusion RatioTax-Free Per MonthTaxable Per Month
Male age 60, $100K SPIA~71%~$390~$160
Male age 65, $100K SPIA~78%~$490~$135
Male age 70, $100K SPIA~86%~$616~$100
Male age 75, $100K SPIA~93%~$790~$60
Female age 65, $100K SPIA~73%~$430~$160

After the exclusion period

If you live PAST your IRS life expectancy, you've recovered all your tax-free principal. All subsequent payments become 100% taxable as ordinary income. For a 65-year-old male, this happens around age 82. So for years 1-17, you get the favorable exclusion ratio; from year 18+, full taxation.

If you die before the exclusion period ends

If you die before recovering all your principal tax-free, your beneficiary may be entitled to deduct the unrecovered basis on the final tax return — under IRC §691(d). Coordinate with the estate's tax preparer. This deduction can be valuable, especially if your beneficiary is in a high tax bracket.

For qualified annuities (IRA / 401k money)

Qualified annuity income is 100% taxable from day 1 as ordinary income — there's no tax basis to recover (you never paid tax on the contributions). The exclusion ratio doesn't apply. This is identical to traditional IRA distributions otherwise.

Exclusion ratio per IRS Pub 575 "Pension and Annuity Income." Treasury Regulation §1.72-9 prescribes mortality tables. §691(d) deduction for unrecovered basis at death.

COLA Rider — Worth The Lower Starting Payout?

A COLA (Cost of Living Adjustment) rider increases your annuity payment each year by a fixed percentage (typically 1-3%). The trade-off: your STARTING payment is 20-30% lower for a 3% COLA rider. The math is rarely favorable for typical retirees.

$100K SPIA (65M, life-only)Year 1 IncomeYear 10 IncomeYear 20 IncomeTotal Years 1-20
Flat (no COLA)$7,500/yr$7,500/yr$7,500/yr$150,000
With 3% COLA rider$5,625/yr (-25%)$7,338/yr$9,860/yr$151,150
Breakeven point of 3% COLA rider: Approximately year 12-14. If you live beyond that, the COLA pays off cumulatively. If you live shorter, flat is better. Given a 65-year-old's 17-year life expectancy, the math is roughly a wash for "average" longevity. For better-than-average longevity (95+), COLA is clearly better.

Take COLA if...

Better-than-average expected longevity (family longevity, excellent health), strong inflation expectations, primary income source for the long term, comfortable with lower initial cash flow.

Take FLAT if... $

Average or below-average expected longevity, already have inflation hedges (SS has COLA built in!), need maximum starting income, plan to use annuity only for fixed expenses.

Better alternative $$

Take FLAT annuity, save the income difference, invest in equities (which historically outpace inflation). At year 12-14, this typically beats the COLA rider — and you keep the principal.

Why most advisors don't recommend COLA riders

  • Social Security already has COLA — for most retirees, SS provides 30-50% of income with built-in inflation adjustment.
  • Investment portfolios provide inflation protection. Your non-annuitized assets grow with markets that historically beat inflation by 4-6%.
  • The 20-30% starting reduction is substantial. You're giving up real income today for inflation protection that may or may not happen.
  • Fixed expenses don't grow with inflation. Mortgage (if fixed), some healthcare premiums, and Medicare Part B base premium grow more slowly than CPI.

COLA rider economics analyzed by Kitces "Real Annuities: Should You Pay The Premium?" Standard finding: flat + invested difference typically wins for healthy retirees with average longevity. Inflation-protected annuities (true CPI-linked) are very rare and even more expensive.

Things to Know

Essential concepts for understanding your results

Payout Options
What are the annuity payout options?

Life only: highest monthly payment, stops at death. Life with period certain (10 or 20 years): pays for life or the guaranteed period, whichever is longer. Joint-and-survivor: continues paying 50-100% to surviving spouse. Lump sum: take all cash at once (fully taxable). Choosing life-only over joint-and-survivor can increase monthly income 15-25% but leaves a surviving spouse with nothing.

Tax Treatment
How are annuity payouts taxed?

Each payment contains a tax-free return of principal and a taxable earnings portion based on the exclusion ratio. A $200,000 annuity expected to pay $400,000 over your lifetime: exclusion ratio = 50%, so $200 of each $400 payment is tax-free. After you recover your entire principal, all remaining payments are fully taxable as ordinary income. Qualified annuities (from 401(k)/IRA) are 100% taxable — no exclusion ratio applies.

Inflation Risk
How does inflation erode fixed annuity payments?

A fixed $2,000/month payment loses 30-40% of purchasing power over 15 years at 3% inflation. By year 20, it buys what $1,100 buys today. Inflation-adjusted annuities cost 20-30% more upfront but maintain purchasing power. Without inflation protection, supplement annuity income with investments that grow above inflation — maintaining 40-50% of your portfolio in stocks even in retirement provides the growth needed to offset fixed-income erosion.

Annuity Payout Calculator: How Much Monthly Income Will Your Annuity Provide?

An annuity payout calculator estimates the monthly or annual income stream you will receive from an annuity based on your premium (lump sum invested), age, payout type, and current interest rate environment. This is the calculation that transforms a savings balance into a guaranteed retirement paycheck.

75$780-$870$28,080-$31,3209.4-10.4%

Rates are approximate and vary by insurer, product type, and current interest rates. Joint-life annuities (covering both spouses) pay approximately 15-25% less per month than single-life. Always compare quotes from 3-5 insurers — rates can differ 5-10% for the same person and premium amount. Immediateannuities.com and CANNEX provide comparison tools.

Why older buyers get higher payouts: The insurer expects to make fewer total payments. A 75-year-old has a shorter life expectancy than a 60-year-old, so each monthly payment can be larger from the same premium. This is why annuities are most attractive at older ages — the payout rate exceeds what most conservative investment portfolios can safely distribute.

Payout Options Explained

Life only (highest monthly): Payments for your lifetime only — stop at death. Best payout rate but highest risk for heirs (if you die early, the insurer keeps the remaining balance). Best for: single retirees with no dependents who want maximum income, or married retirees who supplement with a separate life insurance policy.

Joint and survivor (lower monthly): Payments continue for both spouses' lifetimes. 100% survivor: surviving spouse receives the same payment. 50% survivor: payment drops by half when first spouse dies. Best for: married couples where the surviving spouse needs continued income.

Period certain (middle ground): Payments guaranteed for a minimum period (10, 15, or 20 years). If you die before the period ends, beneficiaries receive remaining payments. Slightly lower monthly than life-only but protects against "dying too soon" risk. Best for: retirees who want guaranteed income but also want to protect heirs.

Cash refund: If total payments received are less than the premium paid at death, heirs receive the difference. Eliminates the risk of "losing money" but reduces monthly payout by 5-10% compared to life-only. Popular for psychological comfort — though mathematically, period certain is usually more efficient.

Frequently Asked Questions

How much income does a $300,000 annuity provide?
At age 65 (life-only SPIA): approximately $1,755-$1,920/month ($21,060-$23,040/year). At age 70: $2,010-$2,220/month. Joint-life (same age couple): approximately $1,500-$1,650/month at 65. Rates vary by insurer — always compare 3-5 quotes. The 2026 rate environment (elevated interest rates) produces the highest annuity payouts in 15+ years.
Is an annuity better than the 4% rule?
They serve different purposes. The 4% rule provides flexible access to your portfolio (withdraw more or less as needed) with market risk. An annuity provides guaranteed income for life with no market risk — but no flexibility or access to the premium. The optimal strategy for most retirees: annuitize enough to cover essential expenses (filling the gap between Social Security and needs), keep the rest invested for flexibility and growth.
When is the best age to buy an annuity?
Late 60s to mid-70s. Younger: the payout rate is lower (longer expected payment period) and you give up decades of investment growth potential. Older: the payout rate is highest and the guaranteed income is most valuable when you are less able to manage investments or work. Buying at 70 with a $300,000 premium: $24,120-$26,640/year guaranteed for life — an 8-9% payout rate that no conservative investment can match.
What happens to my annuity money if I die early?
Depends on the payout type. Life-only: insurer keeps the remaining balance (the trade-off for the highest monthly payment). Period certain (10/15/20 year): beneficiaries receive payments for the remaining guaranteed period. Cash refund: heirs receive the difference between premium paid and total payments received. Joint and survivor: surviving spouse continues receiving payments. Choose the option that matches your legacy goals and need for maximum income.
Are annuity payouts taxable?
Partially. If purchased with after-tax money: each payment is split between taxable earnings and tax-free return of premium (using an exclusion ratio). If purchased with pre-tax money (IRA, 401k rollover): the entire payment is taxable as ordinary income. The exclusion ratio makes after-tax annuities partially tax-sheltered, which can be advantageous for retirees managing their tax bracket.
