The method, explained

Convert annual return to an effective monthly rate. Grow existing savings and add contributions at each month-end. Inflate today’s spending to retirement, then divide by the chosen withdrawal fraction to estimate a scenario target.

A WORKED EXAMPLE

Using current age = 35, retirement age = 65, current savings = 50000 money, monthly contribution = 500 money, expected nominal annual return = 5 %, expected annual inflation = 2 %, desired annual spending in today’s money = 30000 money, annual withdrawal scenario = 4 %, the result is 623785.072 currency.
