A Single Premium Immediate Annuity (SPIA) is the simplest, most transparent annuity product: you write a check, and the insurance company sends you a payment every month for the rest of your life. No investment decisions, no market risk, no minimum distributions — just guaranteed income.
How a SPIA Works
| Step | What Happens |
|---|---|
| 1. Purchase | You pay one lump sum premium to an insurance company |
| 2. Election period | You choose payout options: single/joint life, period certain, COLA, etc. |
| 3. Income begins | Payments begin within 1-12 months (most policies: 30 days) |
| 4. Lifetime guarantee | Payments continue as long as you (and/or spouse) are alive |
| 5. Death provision | Depends on options chosen: payments stop (single life) or continue to beneficiary (period certain) |
The insurance company pools mortality risk: those who die early subsidize those who live long. This “mortality credit” is what makes SPIAs more efficient than self-managing for longevity risk.

Life + 10-Year Period Certain (payments for at least 10 years regardless of death)
| Purchase Amount | Age 65 | Age 70 |
|---|---|---|
| $100,000 | $638/mo | $710/mo |
| $200,000 | $1,276/mo | $1,421/mo |
| $300,000 | $1,914/mo | $2,131/mo |
| $500,000 | $3,190/mo | $3,552/mo |
Joint Life (100% to surviving spouse)
| Purchase Amount | Both Age 65 | Both Age 70 |
|---|---|---|
| $100,000 | $575/mo | $646/mo |
| $200,000 | $1,150/mo | $1,293/mo |
| $300,000 | $1,725/mo | $1,939/mo |
| $500,000 | $2,874/mo | $3,232/mo |
Note: Joint life reduces monthly income by roughly 12-16% vs. single life — the tradeoff for protecting a surviving spouse.
What Affects Your SPIA Payout Rate?
| Factor | Effect on Payout |
|---|---|
| Age at purchase | Older = higher payout (shorter expected payout period) |
| Joint vs. single life | Joint = ~12-16% lower payout per month |
| Period certain guarantee | 10-year certain ≈ 5-8% lower; 20-year certain ≈ 15-20% lower |
| COLA rider (2% annual increase) | Starting payment ~15-20% lower |
| Interest rate environment | Higher rates → higher payouts |
| Insurer competitiveness | Can vary 5-10% from highest to lowest quote among A-rated insurers |
| State of purchase | Minor variation based on state insurance regulations |
Payout Options: Which Combination Makes Sense?
Single Life Only
- Who it’s for: Single retiree without dependents, or married retiree with enough other guaranteed income for spouse
- Upside: Highest monthly payment
- Risk: If you die shortly after purchase, insurer keeps remaining value
Life + Period Certain
- Who it’s for: Retirees who want a “minimum guarantee” in case they die early
- Common periods: 10 years, 15 years, 20 years
- Mechanics: If you die in year 7, surviving beneficiary receives payments through year 10; after 10 years, payments stop at death
Joint Life (100% survivor benefit)
- Who it’s for: Married couples where both spouses depend on the income
- Alternative: Joint Life 50% — payments drop to 50% after first death; higher monthly income than 100% joint
Inflation Rider (COLA)
- How it works: Payment increases by a fixed percentage (typically 2-3%) each year
- Cost: Reduces starting income ~15-20%; takes ~8-10 years to break even vs. non-inflation-adjusted
| COLA Option | Year 1 | Year 10 | Year 20 | Year 30 |
|---|---|---|---|---|
| No COLA | $1,000/mo | $1,000/mo | $1,000/mo | $1,000/mo |
| 2% annual COLA | $820/mo | $1,000/mo | $1,218/mo | $1,485/mo |
| 3% annual COLA | $750/mo | $1,008/mo | $1,354/mo | $1,819/mo |
SPIA Tax Treatment
How SPIA payments are taxed depends on how you paid the premium:
| Funding Source | Tax Treatment |
|---|---|
| Pre-tax IRA or 401(k) | 100% of each payment taxed as ordinary income |
| Roth IRA | 100% of payments are tax-free |
| After-tax funds (taxable account) | Exclusion ratio applies: a portion of each payment is tax-free return of principal |
Exclusion ratio example: A 65-year-old buys a $200,000 SPIA with after-tax money. IRS life expectancy: 20 years. Each $1,450/month payment includes $200,000 ÷ 240 = $833 tax-free return of capital. Only $617/month is taxable.
Once you outlive the exclusion period, 100% of payments become taxable ordinary income.
Insurer Financial Strength: Critical for 30+ Year Commitments
Unlike a bank CD insured by the FDIC, an annuity is backed only by the insurance company’s financial strength (plus state guaranty associations, which typically cover $250,000-$500,000 per person per insurer).
| Rating | Category | Action |
|---|---|---|
| A++ or A+ (AM Best) | Superior | Acceptable for any purchase |
| A or A- (AM Best) | Excellent | Acceptable for most |
| B++ (AM Best) | Good | Use caution; consider splitting among multiple insurers |
| Below B++ | Marginal | Avoid for long-term commitments |
State guaranty associations typically protect $250,000 per person per insurer. If purchasing more than $250,000 in SPIAs, split between 2+ insurers from different holding companies.
How to Shop for a SPIA
- Determine your income need — what monthly gap are you filling?
- Decide on payout options — single vs. joint, period certain, COLA preference
- Get multiple quotes — use ImmediateAnnuities.com or a fee-only financial advisor
- Compare at least 4-6 insurers — rates can differ by 5-10% for the same product
- Check financial strength ratings — AM Best, Moody’s, S&P ratings for all finalists
- Review state guaranty coverage — know your state’s limits
- Consider laddering — purchase 50% now, 50% in 3-5 years at (presumably) higher age and rates
SPIA vs. Other Income Options
| Option | Guaranteed? | Flexibility | Heirs? | Inflation? |
|---|---|---|---|---|
| SPIA | Yes — lifetime | None after purchase | Period certain option only | Rider available |
| TIPS ladder | Real return guaranteed | Can liquidate | Full principal to heirs | Built-in |
| Bond ladder | Nominal return guaranteed | Can liquidate | Full principal to heirs | No |
| Portfolio withdrawal (4% rule) | Portfolio-dependent | Full flexibility | Residual to heirs | Portfolio-dependent |
| Social Security | Yes — government backed | No — claim age is one-time decision | Limited (survivor benefit) | Annual COLA |
How Much to Annuitize: The General Rule
Most financial planners recommend limiting SPIA purchases to the amount needed to cover your essential expense gap after Social Security and other guaranteed income:
Essential expenses − (Social Security + pension + other guaranteed income) = SPIA target
| Essential Monthly Gap | Approximate SPIA Premium (Age 65) |
|---|---|
| $500/month | ~$74,000 |
| $1,000/month | ~$149,000 |
| $1,500/month | ~$223,000 |
| $2,000/month | ~$298,000 |
| $2,500/month | ~$372,000 |
Keep the remaining portfolio in a diversified investment portfolio for growth, inflation protection, and legacy.
Common SPIA Mistakes to Avoid
| Mistake | Why It Matters |
|---|---|
| Buying at 60-62 (too early) | Low payout rate; long period before breakeven; better to delay |
| Not comparing insurers | 5-10% difference in income = real money over 20-30 years |
| Annuitizing too large a portion | Leaves no liquidity for emergencies or unexpected expenses |
| Not considering joint life for married couples | Surviving spouse may face severe income drop |
| Buying from a commissioned salesperson without shopping | Agents often steer toward specific companies; use multiple quotes |
| Ignoring insurer ratings | A-rated insurer with good payout > slight premium at financially weak insurer |
