Step 1 — Estimate today's monthly expense
Track 3 months of spending. Most families underestimate by 20–30%.
Step 2 — Inflate to retirement year
At 6% inflation, ₹50,000/month today becomes ₹2.87 L/month in 30 years.
Step 3 — Apply the 30× rule
Annual expense at retirement × 30 ≈ corpus required (assumes 7% post-retirement return, 3% real withdrawal).
