The Simplest Wealth Formula
Compound interest means earning interest on your interest. It starts slow, then explodes.
Year 1: You invest ₹1,00,000. At 12% return, you earn ₹12,000. Year 2: You now have ₹1,12,000. 12% of that is ₹13,440. Year 10: Your ₹1,00,000 has become ₹3,10,585. Year 20: ₹9,64,629. Year 30: ₹29,95,992.
You invested ₹1,00,000 once. Time did the rest.
The Two Variables That Matter
1. Time
Starting at 25 vs 35 is not a 10-year difference. It's often a 50%+ difference in final corpus. Every year you delay costs lakhs.
2. Consistency
A SIP of ₹5,000/month for 30 years at 12% = ₹1.76 crores. The same ₹5,000/month for 20 years = ₹50 lakhs.
That 10 extra years? Worth ₹1.26 crores.
The Child Advantage
When you start investing for a child at birth, you have an 18-year runway. That's the longest compounding horizon most families will ever have.
Comparison: Start at Birth vs Start at Age 10
| Monthly SIP | Start Age | End Age | Final Corpus | |-------------|-----------|---------|--------------| | ₹5,000 | 0 | 18 | ₹34.2 lakhs | | ₹5,000 | 10 | 18 | ₹8.7 lakhs |
Same amount invested. Four times the difference. That's the power of time.
Don't Wait for "More Money"
The biggest mistake is waiting until you can invest more. ₹1,000/month started today beats ₹5,000/month started five years from now.
Start small. Start now. Let compound interest do the heavy lifting.
What This Means for Your Child's Trust Fund
Every month you delay setting up your child's trust fund is money left on the table. Not because of the amount — because of the time.
