SIP Backtest
Action Construction Equipment Ltd.
A ₹10,000 monthly SIP in ACE over the last 15 years means ₹18,00,000 paid in across 180 instalments. It would be worth ₹4,16,71,003 today.
Change the instalment or the holding period to run the backtest against ACE's own price history. Nothing here is projected from an assumed rate — every figure comes from what the share price and dividends actually did.
Every Period
Each period is a separate backtest: ₹10,000invested at the end of every month, priced at that month's adjusted close. The last instalment falls on the valuation month, so it has had no time to grow — which is exactly true of a real SIP.
12 instalments of ₹10,000 — ₹1,20,000 paid in — would be worth ₹1,43,615 today, an XIRR of 46.0%.
Same money, invested once: ₹1,27,608 (6.9% XIRR) — the SIP did better.
Same SIP into the Nifty 500: ₹1,22,790 (5.1% XIRR) — ACE ahead.
36 instalments of ₹10,000 — ₹3,60,000 paid in — would be worth ₹3,81,672 today, an XIRR of 4.0%.

By Monthly Amount
Each row is a 15-year SIP in ACE, run at a different instalment.
| Every month | Total invested | Worth today | Gain |
|---|---|---|---|
| ₹1,000 | ₹1,80,000 | ₹41,67,100 | +₹39,87,100 |
| ₹2,000 | ₹3,60,000 | ₹83,34,201 | +₹79,74,201 |
| ₹5,000 | ₹9,00,000 | ₹2,08,35,501 | +₹1,99,35,501 |
| ₹10,000 | ₹18,00,000 | ₹4,16,71,003 | +₹3,98,71,003 |
| ₹25,000 | ₹45,00,000 | ₹10,41,77,506 | +₹9,96,77,506 |
SIP outcomes are exactly proportional to the instalment, so these rows scale from one backtest rather than five. The annualised return (XIRR) is identical for every row — only the rupee figures change.
The Metric
A SIP's return cannot honestly be quoted as a CAGR. CAGR describes one sum invested once and left alone; a SIP adds money every month, so the first instalment has been invested for 15 years and the last for a single month. Averaging those as though they were one investment overstates the result.
The correct measure is XIRR — the single annual rate that makes all 180 instalments and today's value balance. For Action Construction Equipment Ltd. over 15 years, that rate is 36.9%.
Most Indian SIP calculators ask you to assume a rate of return — commonly 12% — and then compute forward from it. Nothing on this page is assumed: every figure comes from what the share price and dividends actually did.
SIP vs Lump Sum
₹18,00,000 put into Action Construction Equipment Ltd. as a single lump sum at the start of the period would be worth ₹4,94,96,639 today (24.9% XIRR). The same money paid in monthly is worth ₹4,16,71,003.
The lump sum came out ahead. That is the usual result over a period where the price rose, because money invested earlier had longer to compound — and it is worth stating plainly rather than only showing the SIP figure.
The comparison is not really a choice for most people. A SIP invests what you earn each month; a lump sum requires having the whole amount up front. This tells you what each would have produced, not which you should have done.
SIP vs The Index
The identical 180 instalments put into the Nifty 500 on the same dates would be worth ₹49,86,478 — an XIRR of 12.7%, against ₹4,16,71,003 in Action Construction Equipment Ltd.. ACE is ahead over this period.
The index leg is bought month by month on exactly the same dates, not modelled at an assumed annual rate. That matters: a smooth compounded curve has no entry timing, and entry timing across many instalments is the entire subject of this page.
How This Is Calculated
Each instalment buys at that month's closing price. A real SIP buys on a fixed date that may be any trading day, so an actual outcome would differ a little in either direction.
Prices are adjusted for dividends and stock splits, so dividends are treated as reinvested. Demergers are not credited, and brokerage and taxes are not modelled.
ACEis in today's Nifty 500 universe. Companies that delisted or collapsed are not on this site at all — a bias worth holding in mind when reading any historical backtest.

Everything you need to know about this page and the data presented.
Investing ₹10,000 a month in Action Construction Equipment Ltd. for the last 15 years would have meant paying in ₹18,00,000 across 180 instalments. That holding would be worth about ₹4,16,71,003 today — a gain of ₹3,98,71,003, or 23.1× the money paid in. Every instalment is priced at that month's adjusted close, so dividends and stock splits are already counted in.
A 15 years SIP in Action Construction Equipment Ltd. returned an XIRR of 36.9%. XIRR is the right measure for a SIP and CAGR is not: CAGR assumes one sum invested once, while a SIP puts money in every month, so each instalment is exposed for a different length of time. A 15 years SIP's final instalment has been invested for one month, not 15 years.
Over the last 15 years, no. The same ₹18,00,000 invested as a single lump sum at the start would be worth ₹4,94,96,639 today, against ₹4,16,71,003 for the monthly SIP. The lump sum won because the price rose over the period, so money invested earlier had longer to compound. That is the usual outcome in a rising market, and it is the honest answer rather than the flattering one. A SIP is a way of investing what you earn each month, not a technique for beating a lump sum you already have.
Over 15 years, yes. The identical monthly instalments put into the Nifty 500 instead would be worth ₹49,86,478, against ₹4,16,71,003 in Action Construction Equipment Ltd. — an index XIRR of 12.7%. The index leg is bought month by month on the same dates, not modelled at an assumed rate.
₹5,000 a month for 15 years adds up to ₹9,00,000 paid in, and would be worth about ₹2,08,35,501 today. SIP outcomes scale exactly with the instalment, so halving or doubling the monthly amount halves or doubles every rupee figure and leaves the XIRR unchanged.
₹10,000 a month for 5 years means ₹6,00,000 paid in, worth about ₹13,44,338 today — +124.1% on what went in, an XIRR of 33.9%. Shorter horizons swing far more widely than long ones, which is why this page publishes every period separately rather than picking one.
That is not a question this page answers, and we do not make recommendations. What it can tell you is exactly what a monthly SIP in Action Construction Equipment Ltd. would have produced over every period the data covers, how that compares with the same money invested at once, and how it compares with the Nifty 500. Those are records of what happened, not forecasts — a stock that compounded well for twenty years carries no promise about the next one.
