Frequently Asked Questions

A lumpsum investment is when you invest a large amount at once rather than in installments. For example, investing a ₹5 Lakh bonus or inheritance in a mutual fund as a single payment rather than through monthly SIP. The entire amount benefits from compounding from day one.
SIP spreads risk through rupee-cost averaging and is ideal for salaried individuals. Lumpsum can deliver higher returns if invested at market lows but carries timing risk. If you have a large amount available, consider splitting it: invest part as lumpsum and the rest via a short-term SIP to average out market volatility.
Lumpsum returns use the compound interest formula: FV = PV × (1 + r)^n, where PV is the principal amount, r is the annual return rate (as decimal), and n is the number of years. For example, ₹1 Lakh at 12% for 10 years grows to approximately ₹3.11 Lakh.
