## Questions and answers from the visible page

### What is the difference between lumpsum and SIP investing?

Lumpsum invests the entire amount at once, fully exposed to market timing risk from day one. SIP spreads investment over time, averaging out purchase cost — generally lower risk for volatile markets.

### How is lumpsum maturity value calculated?

Maturity Value = Principal × (1 + Return Rate/100) ^ Years, assuming compounding at a constant annual rate.

### Is lumpsum investing riskier than SIP?

It can be, since the full amount is exposed to market movements immediately — but if markets rise steadily, lumpsum can outperform SIP. The right choice depends on your risk appetite and market view.
