Note
This is not financial advice. It is a simplified model: it applies the displayed standard formula to the figures you entered, assumes a single constant rate for every year, and ignores taxes, fees, sequence-of-returns risk, health costs, longevity risk and any country's specific pension, benefit or minimum-distribution rules. Real returns can be negative and real retirements rarely follow a smooth curve. Check the assumptions and consult a licensed adviser before acting on any figure.

What does this calculator convert?+
It converts a lump sum of capital into an estimated periodic (usually monthly) income stream, based on an assumed interest/discount rate and a payout duration or life expectancy. It mirrors how an insurance company prices an annuity contract, though actual insurer quotes include fees and mortality pricing not captured here.
Why does a higher assumed interest rate produce a higher monthly income?+
Because between payments, the remaining balance keeps earning interest, so a higher rate means more of the payout can come from investment growth rather than depleting principal, allowing a larger regular payment from the same starting lump sum.
What's the difference between a fixed-term payout and a lifetime payout?+
A fixed-term payout (e.g. 20 years) fully exhausts the lump sum by a set date and can be calculated precisely with the interest rate and term; a lifetime payout depends on how long the person lives, so real insurers price it using mortality tables and pool risk across many annuitants, which this type of calculator can only approximate with an assumed life expectancy.
Does the income amount include an inflation adjustment?+
Not unless the calculator explicitly adds one — a plain calculation typically assumes a flat, unchanging payment, so its real purchasing power will erode over time with inflation unless you built in an escalation rate or a higher initial buffer.
Why might a real insurance company quote be different from this estimate?+
Insurers price in their own costs, profit margins, reserve requirements, and mortality risk pooling (especially for lifetime annuities), all of which typically make a real quote lower than a simple time-value-of-money calculation using the same rate and term.
