10.1 Annuity Payout Options and the Exclusion Ratio
Key Takeaways
- Pure life (straight life) pays the largest periodic amount but forfeits all value at death with no beneficiary refund.
- Adding guarantees — period certain, refund, or a joint survivor — always lowers the size of each payment.
- The exclusion ratio = investment in the contract (cost basis) divided by expected return (payment x life expectancy).
- The tax-free portion equals the exclusion ratio times each payment; once full basis is recovered, payments become 100% taxable.
- The annuitant is the measuring life whose age and life expectancy set the payout amount and duration.
Annuity Payout Options and the Exclusion Ratio
An annuity is a contract that systematically liquidates a sum of money, protecting the owner against outliving income (the risk of living too long). The accumulation phase is when money is paid in and grows tax-deferred. The annuitization phase (also called the payout or distribution phase) is when the insurer converts the accumulated value into a stream of payments. This section covers the payout options available at annuitization and how the exclusion ratio determines how much of each payment is taxable.
The parties and key dates
- Owner — controls the contract, names the annuitant and beneficiary, and pays premiums.
- Annuitant — the measuring life; payout amounts and duration are based on this person's age and life expectancy.
- Beneficiary — receives any guaranteed remaining value if the annuitant dies before payments are exhausted.
- Annuity (maturity) date — when the accumulation phase ends and payout begins.
The annuitant and owner are often the same person but need not be. Payments cannot be paid out faster than they are computed on the annuitant's life.
Payout (settlement) options
Annuitants choose how long and to how many lives payments run. Pure life (life-only / straight life) pays the largest periodic check because nothing is guaranteed after death — payments stop when the annuitant dies, even after one check. There is no refund to a beneficiary, so it carries the highest payout but the most forfeiture risk.
Life with period certain guarantees payments for a minimum number of years (e.g., 10 or 20). If the annuitant dies inside that window, the beneficiary collects the balance of the certain period.
More payout options
Life with refund (cash refund or installment refund) guarantees the beneficiary receives at least the principal not yet paid out. Joint life stops at the first death. Joint and survivor continues to the survivor, often reduced (e.g., joint and 2/3 survivor) — payments last until both annuitants die, so each check is smaller. Fixed-period (period certain) pays for a set term regardless of life; fixed-amount pays a set dollar amount until the fund is exhausted. These last two are not based on life expectancy and may leave a balance to a beneficiary.
Comparing the options
| Option | Lives covered | Death-benefit guarantee | Relative check size |
|---|---|---|---|
| Pure life (straight life) | One | None | Largest |
| Life with period certain | One | Balance of certain period | Smaller than pure life |
| Life with refund | One | Unpaid principal returned | Smaller than pure life |
| Joint and survivor | Two | Continues to survivor | Smallest (two lives) |
| Fixed period | None (term) | Balance to beneficiary | Depends on term |
| Fixed amount | None (dollar) | Balance to beneficiary | Depends on amount |
Trap: the more guarantees a payout adds, the smaller each payment becomes. Pure life always pays the most per period.
The exclusion ratio
During payout, each annuity check is part return of principal (the owner's already-taxed cost basis) and part earnings (taxable interest). The exclusion ratio is the fraction of each payment excluded from income tax:
Exclusion ratio = Investment in the contract (cost basis) / Expected return
The investment in the contract is the total of premiums paid (basis). The expected return is the annual payment multiplied by the annuitant's life expectancy in years (from IRS tables) for a life annuity, or the total guaranteed payments for a period-certain payout.
Worked exclusion-ratio example
Suppose an owner paid $100,000 in premiums (cost basis) and elects a life annuity paying $10,000 per year. The IRS table gives a life expectancy of 20 years.
- Expected return = $10,000 x 20 = $200,000
- Exclusion ratio = $100,000 / $200,000 = 50%
- Tax-free portion each year = 50% x $10,000 = $5,000
- Taxable portion each year = the other $5,000 (ordinary income)
After basis is recovered
The 50% split applies each year until the entire cost basis is recovered. For an annuitant who outlives the table life expectancy, all payments after full recovery become 100% taxable ordinary income — the tax-free cushion is exhausted. Conversely, if the annuitant dies before recovering the full basis, the unrecovered investment is allowed as a deduction on the annuitant's final income-tax return. This symmetry ensures the owner is taxed only on true earnings over the life of the contract, never on principal already taxed.
Fixed vs. variable and immediate vs. deferred
A fixed annuity pays a guaranteed minimum interest rate and level payments; the insurer bears investment risk. A variable annuity invests in separate-account subaccounts, so payments rise and fall with market performance and the owner bears the risk — variable contracts are securities requiring a securities license.
An immediate annuity (SPIA) begins payments within one payment period of a single premium; a deferred annuity has an accumulation phase first. Only deferred contracts have meaningful cash value to surrender or exchange before payout begins.
Scenario: choosing a payout
A 67-year-old retiree with no dependents wants the largest monthly check and does not care about leaving a residual. Pure life is the fit. A 67-year-old supporting a younger spouse wants income for both lives — joint and survivor is correct even though each check is smaller. A retiree who fears dying early and wasting premiums but still wants lifetime income should choose life with period certain or life with refund, balancing payment size against a beneficiary guarantee.
An annuitant paid $90,000 in premiums and receives $9,000 per year for a life expectancy of 30 years. Using the exclusion ratio, how much of each annual payment is taxable?
