Inputs and units
Use the units shown for Current age, Retirement age, Current retirement savings ($), Monthly contribution ($), Expected annual return (%), Annual withdrawal rate (%). Required fields cannot be blank. Use zero only where that field and the model allow it. Select Calculate after changing a scenario.
Method and assumptions
Project the current balance and deposits made at each month end using a constant nominal annual return divided by twelve. The number of months is the rounded difference between retirement and current ages. Monthly income is the ending balance times the entered annual withdrawal percentage divided by twelve.
Worked example
With 1,000 initially, 100 deposited monthly and zero return for one year, the ending balance is 2,200. At an illustrative 4% annual withdrawal, that is about 7.33 per month.
Limitations
The retirement target cannot precede current age. Return must exceed -100%, and withdrawal percentage must lie between 0% and 100%. This is not a sustainability or tax model; returns, inflation and withdrawal risks are not simulated.
