Premium Payouts Calculator
An accumulated insurance premium can pay out four ways: one lump sum, a fixed monthly check for a set number of years, a check for life, or a check covering two lives. This premium payouts calculator runs all four modes on your numbers side by side, with life expectancies interpolated from the Social Security Administration’s actuarial life table instead of guesswork. The point is not just the amounts, it is the decision: which payout mode fits your situation.
Life expectancies are interpolated from the Social Security Administration 2020 period life table (2023 Trustees Report). The table here is a nine-point extraction: ages below 40 use the age-40 value and ages above 90 use the age-90 value. Joint-life assumes the joint annuitant is the opposite sex and averages the two expectancies, a simplification, not a carrier’s joint-and-survivor pricing. Actual insurer quotes include their own mortality assumptions and expenses, so treat these figures as estimates.
Quick Answer
With $100,000 of accumulated value at 4%, a 65-year-old man gets $678.07 a month for life (16.9 years of life expectancy), $605.98 a month for 20 years period-certain, or $616.08 a month as a joint-life payout with a 62-year-old partner, versus $100,000 immediately as a lump sum. Lifetime payments total about $137,837.57 if he lives exactly to life expectancy. The lifetime annuity pays the highest monthly check here; the lump sum keeps the most control.
Key takeaways
- This is a mode-decision tool, not a quote engine: it prices lump sum, period-certain, lifetime and joint-life payouts from the same inputs so you can compare the shapes, then you take real quotes from carriers.
- Life expectancy drives the lifetime figures. The tool interpolates the SSA 2020 period life table: 16.9 years for a 65-year-old man, 19.7 for a 65-year-old woman, which is why the same premium buys her a smaller monthly check.
- Every guarantee costs monthly income. The worked example’s lifetime $678.07 falls to $605.98 with a 20-year period-certain and $616.08 joint-life, matching the trade-offs in current single-premium immediate annuity pricing.
- The payout decision is usually irrevocable once annuitization begins, so the comparison deserves care before the contract is signed, not after.

How to use the premium payouts calculator
Enter your numbers, click Compare options, and read the four modes top to bottom. The results stay hidden until you calculate, and Reset restores the worked example.
- Enter the accumulated value, rate, age and sex: these four are required and price the lump sum and lifetime annuity modes. The defaults are the $100,000, 4%, 65-year-old-man worked example.
- Add payout years for the period-certain mode: optional. Leave it blank and the tool skips that mode; enter 20 and it prices a 20-year certain payout with payments to heirs if you die early.
- Add a joint annuitant age for the joint-life mode: optional. The tool assumes the opposite sex and averages the two life expectancies, a simplification disclosed below.
- Read the badge line last: it names which mode pays the highest monthly check on your exact numbers, and the working box under the results shows every intermediate figure so you can check the arithmetic.
The four payout modes, side by side
Each mode spends the same $100,000 differently, and the differences are all about who bears the longevity risk. The worked-example numbers below are live runs of the calculator above.
| Mode | What happens | Worked example |
|---|---|---|
| 1. Lump sum | Everything at once: full control, no guaranteed income, you bear all the risk | $100,000.00 now |
| 2. Lifetime annuity | Highest monthly check for one life; payments stop at death | $678.07/mo |
| 3. Period-certain (20 yrs) | Fixed monthly for exactly 20 years; heirs get the rest if you die early | $605.98/mo |
| 4. Joint-life | Pays while either of two people lives; lower monthly, longer protection | $616.08/mo |
Notice the ordering: adding any guarantee trims the monthly check. The lifetime annuity keeps the full longevity risk with the insurer, so it pays the most per month; the period-certain and joint-life modes hand some protection back to your heirs or partner, and the price of that protection is roughly $60 to $72 a month on this profile. The SEC’s annuities guide and FINRA’s annuities overview describe the same trade-off from the investor-protection side.
How the life-expectancy math works
The lifetime and joint-life modes price longevity, so they need a life expectancy, and this tool takes it from the Social Security Administration’s 2020 period life table, the same table behind the 2023 Trustees Report. The tool holds nine anchor points (ages 40 through 90, by sex) and interpolates linearly between them: a 65-year-old man gets 16.94 years, a 62-year-old woman gets 22.07, and the joint-life mode averages the two into a 19.5-year blended expectancy.
Worked example: i = 4% ÷ 12 = 0.3333% per month, n = 16.94 × 12 = 203.3 months, PMT = 100,000 × 0.0033333 ÷ (1 − 1.0033333−203.3) = $678.07/mo
Two honest simplifications to know about. First, the nine-point table clamps outside its range: ages under 40 reuse the age-40 expectancy and ages over 90 reuse the age-90 one, so a 25-year-old’s lifetime figure is understated against the full SSA table. Second, the joint-life mode assumes the joint annuitant is the opposite sex and blends the two expectancies 50/50, which is not how carriers price joint-and-survivor contracts. Both are disclosed in the results note because they change the numbers. The figures are close to real market pricing anyway: published October 2026 single-premium immediate annuity rates put a 65-year-old man with $100,000 at about $700 a month life-only and around $624 with a 20-year certain, within a few percent of this tool’s $678.07 and $605.98.
Worked example, checked against this exact tool
The defaults are pre-filled, so clicking Compare options reproduces this example exactly. $100,000 accumulated value, 4% annual rate, age 65, male, 20-year period-certain, joint annuitant age 62:
Lifetime payments total about $137,837.57 if he lives exactly to life expectancy ($678.07 × 203.3 months). Try the edge cases yourself: set the rate to 0% and the lifetime figure becomes $100,000 ÷ 163.1 months = $613.20 a month, pure division with no interest; set the period-certain to 5 years and watch it pay $1,841.65 a month, the highest check on the page, because the same $100,000 is spread over far fewer months.
Lump sum or annuity: the pros and cons
There is no universally right answer, only trade-offs that depend on your health, your other income, and your discipline with money. The CFPB’s annuity explainer frames the same choice for consumers.
Lifetime annuity: the case for
- Income you cannot outlive, the core longevity insurance
- Highest monthly check of the annuity modes on most profiles
- Simple budgeting: the same check every month, no investment decisions
- No market risk once payments begin
Lifetime annuity: the case against
- Usually irrevocable once annuitization begins
- Nothing for heirs if you die early (without a certain period or refund)
- Fixed checks lose purchasing power to inflation every year
- No liquidity for emergencies or opportunities
Lump sum: the case for
- Complete control: invest, spend, or pass to heirs as you choose
- Leaves a legacy by default
- Can be rolled into an IRA to stay tax-deferred
- Flexibility for changing plans and emergencies
Lump sum: the case against
- No guaranteed lifetime income; you can outlive the money
- You bear all market and longevity risk
- The full taxable gain can land in a single tax year if taken in cash
- Easy to overspend early and shortchange the later years
Two practical notes the quote funnels rarely mention. Annuity payouts are generally taxed as ordinary income, part return of principal and part earnings, which IRS Publication 575 covers in detail; a lump sum taken in cash concentrates the taxable gain into one year. And a fixed monthly check erodes with inflation: at 3% a year, $678 a month buys roughly what $500 buys today after a decade. Weigh the guaranteed income against that erosion when the lump sum tempts you.
Mode decision vs payout amount: which calculator you need
This page answers “which payout mode,” and it overlaps with the annuity income calculator, which answers “how much per month.” That tool is the payout-amount tool: give it a premium and it computes the monthly annuity figure. This page is the mode-decision tool: it prices all four modes on the same inputs, shows the working for each, and names the highest monthly check, so you can decide between the modes before you fine-tune any one of them. The two overlap on the lifetime-annuity arithmetic by design; use this page to choose the mode, then the amount tool to sharpen the figure you take to carriers. Lottery winners face the same choice in miniature, and the lotto annuity calculator and mega millions annuity payout calculator model the lump-sum-versus-annuity decision for jackpots, while the 403(b) payout calculator compares payout choices for retirement plan balances.
What competing calculators miss
Annuity quote sites describe the four payout options well but mostly funnel you toward carrier quotes instead of computing anything on your numbers. Exam-prep pages list the definitions without a working tool. Single-mode calculators compute one payout figure and leave the comparison to you. This page runs all four modes on your inputs with a real actuarial life table, shows the working line for each mode, prices the guarantee trade-off in dollars per month, and explains the tax and inflation angles that the quote funnels never mention. It is deliberately not a quote: carrier pricing adds each insurer’s own mortality assumptions and expenses, so the decision comes first here and the shopping comes second.
Frequently asked questions
Lump sum, period-certain payments, lifetime annuity, and joint-life annuity. The lump sum pays everything at once; period-certain pays monthly for a fixed number of years; lifetime annuity pays monthly for as long as you live; joint-life pays monthly while either of two people is alive. This tool prices all four on the same inputs.
Usually the single-life annuity, because the insurer keeps the balance if you die early and prices that into a higher check. A short period-certain can pay more per month, since the same value is spread over fewer months. The badge under the results names the highest monthly check on your exact numbers.
An annuity that pays monthly for a fixed number of years, such as 10 or 20. If you die before the period ends, your named beneficiaries receive the remaining payments. It costs some monthly income versus the life-only option: on the worked example, the 20-year certain pays $605.98 a month against the lifetime $678.07.
An annuity covering two people, usually spouses, that keeps paying until the second one dies. The monthly check is lower than a single-life annuity because the insurer expects to pay longer. This tool assumes the joint annuitant is the opposite sex and averages the two life expectancies, a simplification disclosed in the results note.
PMT = PV × i ÷ (1 − (1+i)−n), with i = annual rate ÷ 12 and n = life expectancy in months from the SSA 2020 period life table. For the worked example, i = 0.3333% per month and n = 203.3 months, giving $678.07 a month. The working box under the results shows every intermediate figure.
The Social Security Administration 2020 period life table (2023 Trustees Report), interpolated by age and sex from nine anchor points between ages 40 and 90. Ages below 40 use the age-40 value and ages above 90 use the age-90 value. A 65-year-old man averages 16.9 more years; a 65-year-old woman averages 19.7.
Generally yes, as ordinary income: each payment is partly a tax-free return of principal and partly taxable earnings, a split IRS Publication 575 explains in detail. A lump sum taken in cash can concentrate the taxable gain into a single year, which is one reason rolling it into an IRA is common.
Yes. A fixed check loses purchasing power every year it stays flat: at 3% inflation, a $678 monthly payment buys about what $500 buys today after ten years. Weigh that erosion against the longevity protection when you compare with the lump sum, which you could invest for growth.
It depends on your health, your other guaranteed income, and your investing discipline. The annuity insures against outliving your money; the lump sum gives control and a legacy for heirs. This page prices both so you can see the trade-off in dollars, but the decision is usually irrevocable once annuitization begins, so get carrier quotes and, for large balances, professional advice before you commit.
