Annuity Payout Calculator

A $100,000 immediate annuity for a 65-year-old male with a life-only payout option pays approximately $600 per month, or about $7,200 per year. This annuity payout calculator estimates the monthly and annual income a single-premium annuity would provide based on your premium amount, age, sex, and payout option. It uses an amortization formula for fixed-period annuities and a market-based payout-rate table for life annuities, so you can compare options side by side.

Annuity Payout Calculator Monthly

The monthly payout from an annuity depends on the type of product, the premium paid, and the terms you select. For a fixed-period annuity, the monthly payment is calculated precisely using the amortization formula: the premium is divided into equal payments over the selected term, with each payment including both principal and interest. For a life annuity, the calculation is different. The insurer uses actuarial tables based on your age, sex, and life expectancy to determine a payout rate, then applies that rate to your premium to find the annual and monthly income.

The distinction matters because a fixed-period payment is mathematically exact and driven by the interest rate you select, while a life annuity payment is an estimate based on mortality probabilities. If you live longer than your life expectancy, the life annuity pays more in total than a fixed-period annuity of the same premium. If you die early, a life-only annuity pays less (or nothing beyond the premium if there is no refund). The calculator above handles both modes and shows the relevant output for each.

Monthly income from an annuity is typically lower than withdrawals from an investment portfolio of the same size, because the annuity provides mortality credits: the funds of annuitants who die early subsidize the payments to those who live longer. This pooling is what allows a life annuity to pay more per month than a safe withdrawal rate from a bond portfolio would support for an equivalent lifespan.

Immediate Annuity Income Calculator

An immediate annuity begins paying income within one payment period (usually one month) after you pay the premium. This distinguishes it from a deferred annuity, which accumulates value for years before annuitization. Immediate annuities are also called single-premium immediate annuities, or SPIAs, and are the most straightforward type for generating retirement income.

To use the calculator for an immediate annuity, select one of the life options (Life Only, Life with Period Certain, or Joint Life) and enter your premium, age, and sex. The payout rate table reflects what SPIA products have been paying in the current interest rate environment. If you are comparing an immediate annuity against a fixed-period product, switch the payout option to a fixed period to see the difference in monthly income and total amount received.

A deferred annuity works differently: you make premium payments (or a single premium) during an accumulation phase, and the value grows tax-deferred. When you annuitize, the payout depends on the accumulated value at that point, not the original premium. This calculator does not model the accumulation phase. It estimates the income you would receive if you converted a lump sum into income today, which is the relevant question when comparing an annuity to a lump-sum investment or a pension buyout offer.

How Much Does a $100,000 Annuity Pay per Month

The payout on a $100,000 premium varies primarily by age and the payout option selected. Below is a reference table showing estimated monthly life-only payouts for male and female annuitants at four common ages. These figures are based on the rate table used in the calculator and represent market averages, not insurer-specific quotes.

$100,000 Life-Only Annuity: Estimated Monthly Payout by Age

Age 60: Male $533/mo ($6,400/yr, 6.40%), Female $508/mo ($6,100/yr, 6.10%). Age 65: Male $600/mo ($7,200/yr, 7.20%), Female $571/mo ($6,850/yr, 6.85%). Age 70: Male $675/mo ($8,100/yr, 8.10%), Female $642/mo ($7,700/yr, 7.70%). Age 75: Male $767/mo ($9,200/yr, 9.20%), Female $733/mo ($8,800/yr, 8.80%).

Adding a period-certain rider reduces these amounts. A 65-year-old male with a 10-year period certain would receive approximately $558 per month instead of $600, and a 20-year period certain drops to roughly $483 per month. The reduction occurs because the insurer must guarantee payments to a beneficiary if the annuitant dies within the guarantee period, increasing the expected total payout.

For fixed-period annuities, the monthly payout is driven by the interest rate rather than age. A $100,000 premium at 4.5% over 20 years produces approximately $633 per month, for a total of $151,836 (of which $51,836 is interest). At 6% over 20 years, the same premium pays approximately $716 per month. Fixed-period payouts are the same regardless of age or sex because there is no mortality risk for the insurer to price.

Annuity Payout Calculator by Age

Age is the single most important factor in determining a life annuity payout. The reason is straightforward: the insurer estimates your remaining life expectancy and spreads the premium over that period, with adjustments for the interest it expects to earn on the reserve it holds to fund future payments. A 55-year-old male has a life expectancy of roughly 24 more years, while an 80-year-old male has roughly 8 years. The same $100,000 premium therefore produces a much higher monthly payment at 80 than at 55.

The payout rate at age 65 for a male life-only annuity is approximately 7.2% annually, producing about $600 per month on a $100,000 premium. At age 70, the rate rises to roughly 8.1% ($675/month). At age 75, it climbs to about 9.2% ($767/month). At age 80, it reaches approximately 10.6% ($883/month). These are not guaranteed rates; they reflect market conditions at the time the rate table was compiled. When interest rates rise, annuity payout rates tend to increase because insurers can earn more on the premium reserve. When rates fall, payouts decrease.

The age-payout relationship is why many financial planners recommend annuitizing a portion of retirement savings in your late 60s or early 70s rather than at younger ages. The higher payout rate at older ages means more monthly income per dollar of premium, and the shorter expected payout period means less inflation risk (the purchasing power of fixed payments erodes over time). However, delaying annuitization also means forgoing the mortality credits you would have received during the waiting years.

Fixed Annuity Income Calculator

A fixed-period annuity converts a lump sum into guaranteed monthly payments for a set number of years. The calculation uses the standard loan amortization formula, which is the same math used for a mortgage but in reverse: instead of borrowing money and repaying it, you are lending money (to the insurer) and receiving it back with interest in equal installments.

Worked Example: $100,000 Premium, 4.5% Annual Rate, 20-Year Fixed Period

Monthly rate: 4.5% / 12 = 0.375%. Number of payments: 20 years times 12 = 240. Formula: $100,000 times 0.00375 divided by (1 minus (1.00375) to the -240). Monthly payment: $632.65. Annual income: $7,591.80. Total received: $632.65 times 240 = $151,836. Interest portion: $151,836 minus $100,000 = $51,836. Payout rate: 7.59%. These figures are exact for the stated assumptions.

The interest rate you choose in the calculator is a planning assumption. Actual fixed-period annuity rates depend on the insurer, the prevailing yield on bonds and other fixed-income investments at the time of purchase, and the duration of the payout period. Longer fixed periods typically offer slightly higher rates than shorter ones because the insurer can invest in longer-duration bonds. A 10-year fixed period at 4.0% might produce a payout rate around 12.2%, while a 25-year period at 4.5% might produce roughly 6.7%, reflecting the longer time over which interest accrues.

Unlike life annuities, fixed-period annuities do not provide longevity protection. If you outlive the payment period, the income stops. This makes them suitable for specific goals like funding a child's education over 10 years or bridging the gap between retirement and Social Security, rather than as a primary lifetime income source. The calculator shows the total received and interest portion so you can evaluate whether the effective return meets your objectives.

Frequently Asked Questions

How much does a $100,000 annuity pay per month?

A $100,000 single-premium immediate annuity (SPIA) for a 65-year-old male with a life-only payout option pays approximately $600 per month, or about $7,200 annually. That translates to a payout rate of roughly 7.2% of the premium. A 65-year-old female receives slightly less, around $570 per month, because women have longer life expectancies. These figures are based on recent market averages and change as interest rates shift. A 75-year-old male at the same premium would receive roughly $767 per month because the shorter expected payout period allows a higher rate. The calculator above uses a rate table to estimate payouts for various ages, sexes, and options.

What is the difference between a fixed-period and a life annuity?

A fixed-period annuity pays income for a specific number of years (for example, 10 or 20 years) and then stops, regardless of whether you are alive at the end of the term. The monthly payment is calculated using a standard amortization formula based on the premium, the interest rate, and the number of months. A life annuity pays for as long as you live. If you die early, payments stop (or go to a beneficiary if you have a period-certain rider). If you live longer than average, you continue receiving payments, which is the fundamental risk transfer that makes annuities valuable. Life annuity payouts are determined by the insurer based on your age, sex, and life expectancy rather than a stated interest rate.

Why do annuity payouts increase with age?

Annuity payouts increase with age because the insurer expects to make fewer total payments. A 75-year-old has a shorter remaining life expectancy than a 60-year-old, so the same premium is spread over fewer expected years, producing a higher monthly amount. The payout rate also reflects the interest rate environment: when long-term bond yields are higher, insurers can invest the premium at higher returns and pass some of that through as higher payouts. Conversely, in a low-rate environment, payouts are lower. The age effect is substantial: a 65-year-old male might receive a 7.2% payout rate, while an 80-year-old male could receive 10.6% on the same premium with the same life-only option.

What is a period-certain rider on a life annuity?

A period-certain rider guarantees that payments will continue for a minimum number of years even if the annuitant dies before that period ends. A 10-year period certain on a life annuity means the insurer will pay for at least 120 months. If the annuitant dies in year 3, the remaining 84 months of payments go to the designated beneficiary. If the annuitant lives past 10 years, payments continue for life. Because this guarantee increases the insurer's expected total payout, the monthly payment is lower than a straight life-only annuity. A 20-year period certain reduces the payout further. The tradeoff is between a higher monthly payment (life only) and the security of knowing your beneficiaries will receive payments for a guaranteed minimum term.

Are annuity payouts taxable?

Partially. If you purchase an annuity with after-tax dollars (non-qualified annuity), a portion of each payment is considered a return of your original premium and is not taxed. The remaining portion, which represents earnings, is taxed as ordinary income when received. The exclusion ratio determines the tax-free and taxable portions. For a $100,000 premium expected to produce $180,000 in total lifetime payments, roughly $100,000 divided by $180,000, or about 56%, of each payment would be tax-free return of principal. If the annuity is held inside a qualified retirement account like an IRA or 401(k), the entire payment is taxed as ordinary income because the contributions were tax-deferred. Consult a tax professional for guidance specific to your situation.
