SIP vs Lumpsum Investment: Which is Better?

SIP vs Lumpsum: The Fundamentals

SIP (Systematic Investment Plan) means investing a fixed amount every month in a mutual fund. It buys more units when prices fall and fewer units when prices rise — this is called rupee cost averaging.

Lumpsum means investing a large amount all at once, typically when you have a windfall or receive a bonus.

When SIP Wins

In volatile or falling markets, SIP averages down your cost

For salaried investors with regular income

When you lack market-timing skills (most investors)

For long horizons (10+ years) where regular discipline matters most

When Lumpsum Wins

In rising markets from a trough, lumpsum captures full upside

When you have spare cash sitting idle in savings earning 4%

At market bottoms (hard to identify in real time)

For very short periods where you need full deployment
