How it works
Enter the starting balance, annual return assumption, payout period in years, and payout frequency.
The calculator estimates the periodic payout needed to draw the balance down over the chosen payout window.
It also shows the total payouts over time so the result is easier to compare with the original balance.
Understanding your result
The payout per period is usually the number people care about first, but the return assumption and payout window are what move that number the most. A shorter window or lower return tends to reduce the payout estimate, while a longer window or higher return can support a larger one.
