What is a Lumpsum Investment?
A Lumpsum Investment involves depositing a significant amount of money into a Mutual Fund or other investment vehicle in a single, one-time payment, rather than breaking it down into smaller systematic monthly investments (SIPs). It is heavily utilized when an investor receives a large influx of capital at once, such as an annual bonus, inheritance, or the sale of real estate.
SIP vs Lumpsum?
While a Systematic Investment Plan (SIP) allows you to average your purchase price out over time (reducing market volatility risk), a Lumpsum investment generally yields geometrically higher returns if your overall time horizon is long enough (10+ years), simply because your entire capital base stays in the market and compounds for a much longer period.
The Lumpsum Compounding Formula
A = P(1 + r/n)^(n × t)
Where A is the estimated final maturity amount, P is the principal lumpsum amount invested, r is the expected annual rate of return, and t is the investment duration in years.
