Frequently Asked Questions

How much do I need for retirement?

25-30x annual expenses at retirement. ₹50K/month now with 6% inflation for 25 years → ₹2.15L/month → ~₹6-7 crore corpus.

What is the FIRE 4% rule?

Save 25x annual expenses. Withdraw 4%/year — corpus should last 30+ years.

When should I start?

As early as possible! Starting at 25 vs 35 halves the required monthly savings due to compounding.
