How to read this tool What each input changes
Two ways to deploy the same money: drip it in monthly, or commit it all at once. On identical assumptions, this races the two side by side.
- Monthly SIP amount
- What the SIP lane invests each month. Its money goes in gradually, so the average rupee compounds for only part of the horizon.
- Lumpsum amount
- What the lumpsum lane invests on day one. Every rupee gets the full horizon to compound, which is its structural advantage.
- Expected annual return
- The yearly growth, applied equally to both lanes so the comparison stays fair.
- Investment period
- The shared horizon. The longer it runs, the more a lumpsum's early head start tends to tell.
Which strategy is better?
It depends on what you have. If you have a lumpsum and don't need it for years, deploying it (in one go or via an STP) usually wins because every rupee compounds from day one. If you have a monthly surplus instead, SIP is the natural fit — and rupee-cost-averaging cushions you from buying at peaks.
Does timing the market matter?
For lumpsum, somewhat — buying near market peaks hurts more. For SIP, much less — monthly instalments average out the entry price by definition. Most retail investors are better off committing to a SIP discipline than trying to time lumpsum deployment.
What if I have a lumpsum but want to deploy gradually?
Use an STP — it stages the lumpsum into equity month by month from a parked liquid fund. The Compare above doesn't model STP explicitly, but the answer for STP usually sits between SIP and lumpsum.
Are returns taxed differently?
No — taxation depends on the fund (equity vs debt) and holding period, not on whether you deployed via SIP or lumpsum. Each SIP instalment, however, has its own holding-period clock for the LTCG calculation, which can be material if you redeem within a year of any recent instalment.
