Lumpsum vs SIP

A lumpsum invests a single amount all at once, so it works best when you have a windfall (a bonus, maturity proceeds) ready to invest and are comfortable with market timing. A SIP spreads smaller amounts across months, averaging your purchase price. Many investors use both: a lumpsum for money they have now, and a SIP for money they save each month.

A note on returns

The growth shown assumes a steady annual return, which is an illustration only. Market-linked investments are not guaranteed and returns vary year to year, including negative years. Treat any rate you enter as illustrative rather than promised.

Frequently asked questions

How is lumpsum return calculated?+

It uses compound growth: final value = amount x (1 + annual return)^years. Each year's growth is added to the base, so returns compound over time.

Is a lumpsum better than a SIP?+

Neither is universally better. A lumpsum can do well if markets rise after you invest, but worse if they fall soon after. A SIP averages your entry across months. Use a lumpsum for money you have now, a SIP for monthly savings.
