Frequently asked questions
- What formula does this use?
- Payout = P × r ÷ (1 − (1 + r)^−n), where P is the balance, r the monthly rate and n the number of monthly payments. For payments at the start of each month the result is divided by (1 + r).
- Does this work for a lifetime annuity?
- It models a fixed-period (period-certain) payout. Life annuities from insurers also price in mortality, so their quotes can be higher or lower.
- Are taxes or fees included?
- No. Insurer fees, riders and income tax reduce what you actually receive.
- What about inflation?
- Payments here are level. With inflation, their purchasing power falls each year.
- Is my data private?
- Yes. Everything is calculated in your browser.
