When does lumpsum make sense?

Lumpsum investing puts a single large amount to work all at once. It's the right choice when you receive a windfall (Diwali bonus, inheritance, ESOP payout) and have a long enough horizon (typically 5+ years) to ride out short-term volatility.

The compounding formula

We use the standard compound interest formula: FV = P × (1+r)ⁿ, where P is your principal, r is the annual return, and n is the number of years. Compounding gets stronger the longer you stay invested. Small differences in rate or time produce huge differences in final wealth.

Lumpsum vs SIP: which to pick?

Lumpsum has a slight statistical edge over SIP across long horizons because more money is invested earlier. But it carries timing risk: if you invest right before a market crash, you'll watch your money fall for months. If you can stomach volatility, lumpsum. If you can't, SIP or a Systematic Transfer Plan (STP).
