About this Tool

The FIRE (Financial Independence, Retire Early) simulator inflates your current monthly expenses to your retirement age, then applies the 25x rule (4% safe withdrawal rate) to find your target corpus. It also back-calculates the monthly SIP needed to bridge the gap after growing your current savings.
