Lumpsum vs SIP
While a lumpsum investment can potentially yield higher returns if the market performs well immediately after your investment, a Systematic Investment Plan (SIP) offers the advantage of rupee cost averaging, reducing the impact of market volatility.
When to choose lumpsum investment
- Market Lows: When markets are at a low point and expected to rise
- Windfall Gains: When you receive a large sum (like a bonus or inheritance)
- Long Investment Horizon: When you have a long time horizon to ride out market fluctuations
- Low Volatility Investments: For relatively stable investments like debt funds
Lumpsum Calculation Formula
The future value of a lumpsum investment is calculated using the compound interest formula:
FV = P × (1 + r)^t
Where:
- FV = Future Value
- P = Principal (Initial Investment)
- r = Rate of Return (in decimal)
- t = Time Period (in years)
For inflation-adjusted value:
Real FV = FV / (1 + i)^t
Where:
- Real FV = Inflation-adjusted Future Value
- i = Inflation Rate (in decimal)
