About the Financial Freedom Calculator
The amount you need is your yearly expenses (minus any passive income such as rent or pension) divided by a safe withdrawal rate. At 4% that is 25 times your yearly expenses; at 3.5%, about 29 times. Because Indian inflation is higher than in the US, many planners use 3–3.5%.
The calculator grows your investments and monthly savings at your expected return while the money you need grows with inflation, and finds the month the two meet. It also shows how the answer changes with different withdrawal rates.
