What This Calculator Does
This annuity payout calculator helps retirees, pre-retirees, and financial planners estimate the monthly income from a lump sum annuity investment. It supports both lifetime and fixed-period payout options and uses 2026 immediate annuity rate benchmarks based on age, gender, and payout type. The calculator shows monthly and annual income, total lifetime payouts, break-even age, effective return, and payout ratio to help you evaluate whether an annuity is the right income strategy for your retirement.
The Formula
For immediate annuities, the payout rate is determined by the insurance company based on your age, gender, and current interest rates. Older annuitants receive higher payout rates because the expected payout period is shorter. For fixed-period annuities with a specified rate, the standard annuity payment formula (PMT) calculates equal monthly payments that fully deplete the principal over the payout period. The break-even age is when total payouts received equal the original investment.
Step-by-Step Example
Enter lump sum
You have $500,000 to invest in an immediate annuity.
Enter age and gender
Age 65, male. Life expectancy estimate: 79 years (14-year payout period).
Select payout type
Lifetime payout. Approximate payout rate for a 65-year-old male in 2026: 6.8%.
Review results
Monthly income: approximately $2,833. Annual income: $34,000. Total lifetime payout: $476,000. Break-even age: approximately 80.
Real-World Use Cases
Retirement Income Planning
Determine how much guaranteed monthly income an annuity can provide as part of a diversified retirement income strategy alongside Social Security and investment withdrawals.
Pension Buyout Decisions
Compare a lump sum pension buyout to the annuity equivalent to decide whether to take the lump sum or the monthly pension payment.
Longevity Risk Protection
Evaluate whether a lifetime annuity makes sense for someone concerned about outliving their savings, especially for those with family history of longevity.
Common Mistakes to Avoid
Comparing annuity payout rates directly to investment returns. Annuity payouts include a return of your own principal, so a 7% payout rate is not the same as a 7% investment return.
Not considering inflation. Fixed annuity payments lose purchasing power over time. A $3,000 monthly payment will buy significantly less in 20 years without inflation adjustments.
Putting too much of your portfolio into an annuity. Financial advisors typically recommend annuitizing only 25% to 40% of retirement assets to maintain liquidity and flexibility.
Ignoring the break-even age. If you do not live past the break-even age, you will have received less than you invested. Consider your health and family history.
Not shopping multiple insurance companies. Payout rates can vary 10% to 15% between insurers for the same age and investment amount.
