How The Tracker Works

The 4% Rule

Freedom Number = (Target Monthly Spending × 12) ÷ 0.04

Example: If you want to spend $4,000/month in retirement: $4,000 × 12 = $48,000/year. $48,000 ÷ 0.04 = $1,200,000.

Years to Freedom Calculation

The tracker simulates your investment growth month by month using:

New Balance = Current Balance × (1 + Monthly Return) + Monthly Contribution

It continues until your balance reaches or exceeds your Freedom Number, then reports how many years it took.

What-If Scenarios

The tool automatically shows you how small changes affect your timeline:
