Example: With a $500,000 retirement account earning 5% annually, you can withdraw $3,299 monthly for 20 years. Over that time, you'll receive $791,760 total - earning $291,760 in interest during the payout phase. Alternatively, $2,500/month from the same balance lasts 28.5 years.
Tip: The 4% rule suggests withdrawing 4% of your balance annually (adjusted for inflation) for a high probability of funds lasting 30 years.

Understanding Your Results
Sustainable retirement income balances payout size, duration, and portfolio growth. Here's how to evaluate your results.
| Result | Meaning | Action |
|---|---|---|
| Payment < 4% of balance annually | Very sustainable | High probability of funds lasting 30+ years; may leave inheritance |
| Payment = 4-5% of balance annually | Sustainable | Reasonable balance of income and longevity for most retirees |
| Payment = 5-7% of balance annually | Aggressive | Suitable for shorter time horizons or with guaranteed income backup |
| Payment > 7% of balance annually | High depletion risk | Funds may run out; consider reducing withdrawals or delaying retirement |

About Annuity Payout Calculator
Formula
PMT = PV × [r(1+r)^n] / [(1+r)^n - 1] Where PMT is the periodic payment, PV is the present value (account balance), r is the periodic interest rate, and n is the number of payment periods. For duration: n = ln(PMT/(PMT-PV×r)) / ln(1+r).
Current Standards: Insurance annuities guarantee lifetime payments based on actuarial tables. Systematic withdrawals from portfolios depend on actual investment returns and carry sequence-of-returns risk.
Frequently Asked Questions
What's a safe withdrawal rate for retirement?
The traditional 4% rule (withdraw 4% of initial balance, adjusted for inflation) has historically provided a 95% chance of funds lasting 30 years. Current low interest rate environments have led some advisors to recommend 3-3.5%. Your specific rate depends on age, risk tolerance, and other income sources.
How does the interest rate affect my payout?
Higher interest rates significantly increase sustainable payouts. At 3% return, $500,000 provides $2,829/month for 20 years. At 6%, the same balance provides $3,582/month - a 27% increase. This is why investment strategy matters even in retirement.
Should I buy an insurance annuity or do systematic withdrawals?
Insurance annuities provide guaranteed lifetime income but typically offer lower payments and no inheritance. Systematic withdrawals offer more flexibility, potential for higher payments, and money for heirs, but carry the risk of outliving funds. Many retirees use a combination.
How does payout frequency affect my results?
More frequent payouts (monthly vs annually) mean slightly less total payout because your balance has less time to earn interest between withdrawals. The difference is typically 1-2% over the payout period. Monthly payments provide more predictable cash flow for budgeting.
What if I need to change my payout amount later?
With systematic withdrawals, you can adjust anytime based on needs and balance. Run new calculations whenever you change amount or frequency. If spending less than calculated, your funds last longer. If spending more, recalculate duration to avoid running short.
