Lean FIRE

Find your FI number targeting a leaner post-FI lifestyle.

ⓘ How this works

Lean FIRE is a version of "Financial Independence, Retire Early" where you plan to live on a smaller, leaner budget after retiring — spending less than you do today — which means you need a smaller total savings target to become financially independent. This calculator estimates that reduced FI number and how many years it might take to reach it.

Your lean FI number
₹1.05 Cr
That's 30% less than the ₹1.5 Cr you'd need for standard FIRE — because you're planning to live on a smaller budget after retiring, not because your investments grow any differently.

This is the total savings you'd need so your investments alone can cover your monthly expenses forever, without ever running out.
