Deposits go in at the end of the month. The return does not drop for fees, tax, or inflation. A 4% rate is a planning assumption, not a promise.

How this is calculated
Spending divided by the withdrawal rate
target = annual spending ÷ withdrawal rate
| withdrawal rate | The share of the portfolio you plan to spend each year. 4% is 0.04. |
|---|---|
| required monthly | The end-of-month deposit that hits the target by the age you chose. |
A 4% rate is a convention, not a promise that the money lasts. A bad sequence of returns can empty a portfolio that looked large enough.
The age estimate stops at 80 years of saving. If the target is still out of reach, the page says so instead of inventing an age.

Is 4% the right withdrawal rate?
It is a starting assumption from a fixed-rate study, not a rule for every market or every retirement length. Type the rate you are willing to plan on.
Does this include a pension or Social Security?
No. Lower the annual spending by the income you expect from elsewhere if you want the portfolio to cover only the gap.
Why is the required monthly different from what I already save?
The required figure is aimed at the age you typed. The estimated age uses the monthly amount you actually save.
