What Is a Systematic Investment Plan (SIP)?

A Systematic Investment Plan (SIP) allows investors to invest a fixed amount at regular intervals (e.g. monthly) into mutual funds or equity assets. It leverages dollar-cost averaging to reduce timing risk.

What Is a Lump Sum Investment?

A Lump Sum investment involves committing an entire investment amount upfront into a single asset or portfolio at one specific point in time.

Key Differences & Strategy Breakdown

Dollar-Cost Averaging: SIP automatically buys more units when prices fall and fewer when prices rise, smoothing out market volatility.
Time Value of Money: Lump Sum investments benefit maximum compounding when markets trend upward consistently over long horizons.
Risk Profile: Lump Sum carries higher market-entry timing risk, whereas SIP is ideal for disciplined salary-earning investors.
