Lumpsum Calculator

There's a moment many Indians experience — a bonus arrives, a property is sold, or an inheritance lands in your bank account — and suddenly you have a lump sum sitting idle. The question is always: "Do I invest it all at once, or spread it out?"

Lumpsum investing puts your entire capital to work from Day 1, maximising the compounding period. A ₹10 lakh investment at 12% annual return becomes ₹30.9 lakhs in 10 years and over ₹93 lakhs in 20 years — without adding a single additional rupee. The math is simple; the discipline is harder.

The risk is timing. If you invest a lump sum right before a market crash, you could see your portfolio drop 30% in months. The solution? Park your lump sum in a liquid or arbitrage fund first, then deploy it into equity via a Systematic Transfer Plan (STP) over 6–12 months. This way you still get rupee cost averaging while your idle capital earns liquid fund returns.

Lumpsum works best for money you can genuinely leave untouched for 7+ years. The more time you give it, the less timing matters — because markets historically recover and compound beyond the original peak.
