What $600,000 Pays at Different Rates (21-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 | 21-Year Total |
|---|---|---|---|---|
| 3.5% | $3,366/mo | $40,386/yr | $403,861 | $807,721 |
| 4.0% | $3,523/mo | $42,277/yr | $422,769 | $845,538 |
| 4.5% | $3,685/mo | $44,216/yr | $442,164 | $884,328 |
| 5.0% | $3,850/mo | $46,204/yr | $462,037 | $924,075 |
| 5.5% | $4,020/mo | $48,238/yr | $482,379 | $964,757 |
| 6.0% | $4,193/mo | $50,318/yr | $503,177 | $1,006,354 |
| 6.5% | $4,370/mo | $52,442/yr | $524,421 | $1,048,843 |
Note: 4% Rule on $600,000 = $2,000/month — withdrawing from an invested portfolio with no income guarantee. All annuity figures assume a period-certain 21-year term at the stated rate.
How Age at Purchase Changes the $600,000 Payout
Purchasing later means a shorter payout term — which concentrates the same $600,000 into fewer years, producing a higher monthly check. Each row below links to a dedicated analysis page for that scenario.

|---|---|---|---|---|
| Age 50 | 35 years | $2,657/mo | $3,028/mo | $3,421/mo |

What $3,850/Month Means for Retirement at 64
Social Security Integration
The average Social Security benefit for a new retiree in 2026 is $1,907/month. Adding $3,850/month in annuity income creates a guaranteed floor of $5,757/month ($69,088/year). This combination exceeds the median U.S. household income of $58,000/year — a substantial income floor.
Inflation: What $3,850 Is Worth in 10 Years
At 3% annual inflation — the Federal Reserve's long-run target — $3,850 today buys the equivalent of $2,865 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?
A 64-year-old has a 50% probability of living past 84–85; a 21-year payout term targets income through age 85. A 21-year term from age 64 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 64
Qualified annuity income of $3,960/month ($47,520/year) plus Social Security will put most single filers into IRMAA tier 1–2 territory. Splitting funding between qualified and non-qualified sources — only the earnings portion of non-qualified payments counts toward MAGI — can hold down Medicare surcharges meaningfully.
Three Ways to Use $600,000 at 64
An annuity is not the only option. Below is an honest comparison of three income strategies for a 64-year-old with $600,000.
Inflation Impact: Real Purchasing Power of $3,850/Month Over 21 Years
At 3% annual inflation, the real purchasing power of a fixed $3,850/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, $3,850 in 2026 has the purchasing power of only $2,070 in real terms by year 20. A COLA rider or paired growth portfolio can partially offset this erosion.
