How to Build a ₹1 Crore Retirement Corpus: Step-by-Step Plan

A practical roadmap to your first crore — starting SIPs, step-up strategy, and realistic timelines based on your starting age.

1.The ₹1 crore timeline by starting SIP amount

At 12% CAGR: **₹5,000/month**: 21.5 years to ₹1 crore. **₹10,000/month**: 16.3 years. **₹15,000/month**: 13.5 years. **₹20,000/month**: 11.7 years. **₹30,000/month**: 9.4 years. **₹50,000/month**: 7.2 years. With a 10% annual step-up starting ₹5,000: **15.5 years** to ₹1 crore (6 years faster than flat ₹5,000). The step-up is the secret weapon for early-career investors.

2.Step 1: Start with any amount today

The biggest barrier to ₹1 crore is not the amount — it's starting. A ₹5,000 SIP started today at age 25 reaches ₹1 crore by age 46 (at 12%). The same ₹5,000 started at age 30 reaches ₹1 crore by age 51. Five years of delay costs you five years of compounding — or requires doubling your SIP to compensate. Open a free demat account (Zerodha/Groww), pick a Nifty 50 index fund, and start a ₹5,000 SIP. Do this before anything else.

3.Step 2: Step up aggressively in years 1-10

Every time you get a raise, increase your SIP by 50% of the raise. Starting ₹5,000 at age 25 with 15% annual step-up (realistic for IT careers): Year 1: ₹5,000. Year 5: ₹10,114. Year 10: ₹20,228. Year 12: ₹26,700. Corpus at year 12: **₹49 lakh**. Year 15: ₹38,000. Corpus: **₹1.07 crore**. You hit ₹1 crore in 15 years starting with just ₹5,000/month.

4.Step 3: Don't interrupt compounding

The single biggest threat to your ₹1 crore goal is redeeming early. Every time you withdraw from your equity SIP for a vacation, gadget, or "temporary" need, you break the compounding chain. ₹1 lakh withdrawn in year 5 costs you ₹6.1 lakh in year 15 (at 12% CAGR). Keep your retirement SIP in a separate fund that you never touch. Use a different fund for short-term goals.

5.Key takeaway

Building ₹1 crore requires starting early, stepping up consistently, and never interrupting compounding. A 25-year-old starting ₹5,000/month with 15% annual step-up crosses ₹1 crore by age 40.
