There is a moment in every financial decision where you stop reading and start calculating. Compare Systematic Investment Plan with one-time investment. This guide is written for that moment. Plain language, one worked example, and a calculator you can open in the next line if you would rather skip straight to your own figures.

Prefer to start with your own figures? Use the SIP vs Lumpsum now, or continue for the formula and a worked example.
The logic, in plain language
Compare the final value of investing a fixed amount every month versus a single one-time investment of the same total capital.
The formula behind it:
FV(SIP) vs FV(Lumpsum)
| Symbol | What it means |
|---|---|
SIP |
Monthly Investment |
Lumpsum |
Total Capital invested at once |
Nothing is rounded away quietly and nothing is assumed on your behalf. If a figure appears in the result, it came from something you entered.
Putting real figures through it
Comparing ₹10k monthly for 10 years vs ₹12L one-time for 10 years.
Change any one input and watch the result move — that sensitivity is the real lesson. It is far more useful than memorising a single outcome, because your own rate, tenure or contribution will never match the example exactly.
Using the SIP vs Lumpsum, step by step
- Open the SIP vs Lumpsum.
- Enter your figures. Use the ones on your statement, sanction letter or scheme document rather than a remembered number.
- Read the result card — the headline figure plus the breakdown that produced it.
- Adjust one input at a time to see what genuinely moves the outcome.
- Tap Download PDF to keep a copy of the calculation, with your inputs and assumptions printed on it.
The PDF takes a few seconds to build because it is a properly typeset report, not a screenshot. You will see a progress message while it is being prepared, and the download starts on its own.
Things worth knowing before you decide
- SIP is generally safer due to rupee-cost averaging.
- Lumpsum can be better in long bull markets if capital is available.
Where people usually slip up
- Assuming one is always better than the other without considering risk.
If you want to go a level deeper afterwards, read up on rupee cost averaging. Both come up the moment you start comparing options seriously.
