What $100,000 Pays at Different Rates (15-Year Term)
Current MYGA and fixed annuity rates range from 4.0% to 6.5% for most carriers in May 2026. The table below shows the full income range — and compares each rate against the commonly cited 4% withdrawal rule.
| Rate | Monthly | Annual | 10-Year Total | 15-Year Total |
|---|---|---|---|---|
| 3.5% | $715/mo | $8,579/yr | $85,786 | $128,679 |
| 4.0% | $740/mo | $8,876/yr | $88,763 | $133,144 |
| 4.5% | $765/mo | $9,180/yr | $91,799 | $137,699 |
| 5.0% | $791/mo | $9,490/yr | $94,895 | $142,343 |
| 5.5% | $817/mo | $9,805/yr | $98,050 | $147,075 |
| 6.0% | $844/mo | $10,126/yr | $101,263 | $151,894 |
| 6.5% | $871/mo | $10,453/yr | $104,533 | $156,799 |
Note: 4% Rule on $100,000 = $333/month — withdrawing from an invested portfolio with no income guarantee. All annuity figures assume a period-certain 15-year term at the stated rate.
How Age at Purchase Changes the $100,000 Payout
Purchasing later means a shorter payout term — which concentrates the same $100,000 into fewer years, producing a higher monthly check. Each row below links to a dedicated analysis page for that scenario.

|---|---|---|---|---|
| Age 50 | 35 years | $443/mo | $505/mo | $570/mo |

What $791/Month Means for Retirement at 70
Social Security Integration
The average Social Security benefit for a new retiree in 2026 is $1,907/month. Adding $791/month in annuity income creates a guaranteed floor of $2,698/month ($32,374/year). BLS data shows median annual spending for households headed by a 65–74 year-old is approximately $58,000. Additional portfolio withdrawals may be needed for discretionary spending.
Inflation: What $791 Is Worth in 10 Years
At 3% annual inflation — the Federal Reserve's long-run target — $791 today buys the equivalent of $588 in 2036. A standard period-certain annuity pays a fixed nominal amount; inflation erodes real purchasing power over time. To partially offset this, some retirees pair a fixed-payout annuity with a TIPS ladder or small equity portfolio. Others purchase a COLA rider (typically 2–3% annual increases) at the cost of a lower starting payment.
Longevity: Does the Term Fit?
At 70, the average American has a 50% chance of reaching 84 and a 25% chance of reaching 91. A 15-year term from age 70 pays through age 85. This covers the median life expectancy for both sexes. For those concerned about outliving a period-certain term, a life-with-period-certain annuity guarantees both longevity protection and income certainty, typically at a modestly lower starting payment.
Tax Treatment at 70
A $100,000 qualified annuity generating $660/month ($7,920/year) at age 65 adds modestly to taxable income — typically staying in the 12–22% federal bracket depending on other income sources. IRMAA Medicare premium surcharges begin above $106,000 MAGI in 2026. Consult a tax professional to model the full impact of annuity income on Medicare premiums if healthcare cost optimization is a priority.
Three Ways to Use $100,000 at 70
An annuity is not the only option. Below is an honest comparison of three income strategies for a 70-year-old with $100,000.
Inflation Impact: Real Purchasing Power of $791/Month Over 15 Years
At 3% annual inflation, the real purchasing power of a fixed $791/month payment erodes significantly. The chart below compares nominal income (what your check says) with real purchasing power (what it buys).
At 3% annual inflation, $791 in 2026 has the purchasing power of only $508 in real terms by year 15. A COLA rider or paired growth portfolio can partially offset this erosion.
