What it is
The FIRE (Financial Independence, Retire Early) number is annual expenses divided by a safe withdrawal rate. This calculator adds a savings projection so you can see when you'll reach it.
Who it's for
Anyone pursuing early retirement or financial independence, from Lean-FIRE to Fat-FIRE targets.
When to use it
Use it once a year to recalibrate — as expenses and contributions change, so does the target and timeline.
