Frequently asked questions
- How is an annuity payout calculated?
- By amortizing the principal over the payout period: Payment = P × r ÷ [1 − (1 + r)^−n], where r is the monthly rate and n the number of months. The payment exactly exhausts the balance at the end of the term.
- Why does the total payout exceed the principal?
- Because the unpaid balance keeps earning interest throughout the payout period. Over 20 years at 5%, a $500,000 principal pays out about $791,947 in total.
- What is the difference between this and a lifetime annuity?
- This is a period-certain annuity that pays for a fixed number of years. A lifetime annuity pays as long as you live, so its payment depends on actuarial life expectancy rather than a fixed term.
- Does this include fees or taxes?
- No. Real annuity contracts include fees, surrender charges, and taxes on the earnings portion of each payment. This is a pre-fee, pre-tax estimate for planning purposes.
