SIP or lump sum

Investing a bit every month or all at once. What each is good at.

Two ways in

A SIP invests a fixed amount every month. A lump sum invests all of it at once. Both buy units of the same fund at that day's NAV.

Side by side

SIP or lump sum

SIP

  • A fixed amount every month
  • Fits money that arrives monthly
  • Buys more units when prices are low

Lump sum

  • All of it at once
  • Fits a bonus or savings you already have
  • More time in the market

Guess first

₹1.2 lakh for 10 years at an assumed 12% a year. Which ends up bigger?

  1. All of it at once
  2. ₹1,000 a month
  3. The same
See the answer

All of it at once. At once, it could grow to about ₹3.73 lakh. ₹1,000 a month (also ₹1.2 lakh in total) could reach about ₹2.24 lakh. The lump sum had longer in the market. An illustration; real returns go up and down.

So which one

If you have a lump sum and a long goal, investing it sooner has usually done better than waiting. If you're nervous about timing, split it over 6 to 12 months. For money you earn each month, a SIP is the natural fit.

Myth

A SIP protects me from losses.

Fact

A SIP spreads out when you buy, but the fund can still fall. What protects you is time and matching the fund to your goal.

Stopping is easy

You can pause or stop a SIP whenever you want, with no penalty from the fund. Your existing units stay invested.

Words from this lesson

  • Lump sum: Investing a large amount at once instead of monthly.
  • Rupee cost averaging: Buying more units when prices are low and fewer when high, by investing a fixed amount.
  • STP: Systematic transfer plan: moving a fixed amount from one fund to another every month.
