This tool compares two ways of investing the same money: spreading it across monthly instalments (SIP) versus investing it all at once (lumpsum). The right choice is rarely about which is “better” in the abstract — it depends on how much you have ready, your comfort with risk, and how the market behaves after you invest.
A lumpsum puts your entire amount to work immediately, so it enjoys maximum time in the market. That is an advantage when markets rise steadily, but a disadvantage if they fall soon after. A SIP invests gradually, which spreads your entry across many price points (rupee cost averaging) and cushions you against a badly timed entry — at the cost of leaving part of your money uninvested for longer.
Enter your amount, expected return, and period, then use the Market Scenario toggle to switch between a steady market and a volatile one. Watch how the outcome for SIP versus lumpsum changes — this makes the trade-off concrete rather than theoretical.
Rule of thumb: if you have a large amount ready and a long horizon, a lumpsum (or STP) often wins. If the money comes from monthly income, a SIP is the natural and disciplined choice.
No. A SIP spreads entry across multiple dates, which can reduce the impact of a single unfavourable entry point, but this doesn't guarantee a better outcome. In a market that rises steadily from your entry point, a lumpsum typically produces a larger corpus because more money compounds for longer.
When the full capital is available upfront, immediate investment gives the entire amount more time in the chosen asset, while staged deployment spreads entry points over time. Which produces the better outcome depends on subsequent returns and what the undeployed capital earns while waiting. If using an STP, there is no universally optimal staging period.
A Systematic Transfer Plan invests your lumpsum in a low-risk debt fund and automatically transfers a fixed amount into an equity fund at regular intervals — combining immediate deployment with the averaging benefit of a SIP.
