SIP Backtest
Indian Bank
A ₹10,000 monthly SIP in INDIANB over the last 15 years means ₹18,00,000 paid in across 180 instalments. It would be worth ₹1,11,52,100 today.
Change the instalment or the holding period to run the backtest against INDIANB'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 ₹1,26,010 today, an XIRR of 11.1%.
Same money, invested once: ₹1,44,057 (22.0% XIRR) — the lump sum did better.
Same SIP into the Nifty 500: ₹1,22,790 (5.1% XIRR) — INDIANB ahead.
36 instalments of ₹10,000 — ₹3,60,000 paid in — would be worth ₹5,46,691 today, an XIRR of 30.7%.

By Monthly Amount
Each row is a 15-year SIP in INDIANB, run at a different instalment.
| Every month | Total invested | Worth today | Gain |
|---|---|---|---|
| ₹1,000 | ₹1,80,000 | ₹11,15,210 | +₹9,35,210 |
| ₹2,000 | ₹3,60,000 | ₹22,30,420 | +₹18,70,420 |
| ₹5,000 | ₹9,00,000 | ₹55,76,050 | +₹46,76,050 |
| ₹10,000 | ₹18,00,000 | ₹1,11,52,100 | +₹93,52,100 |
| ₹25,000 | ₹45,00,000 | ₹2,78,80,251 | +₹2,33,80,251 |
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 Indian Bank over 15 years, that rate is 21.9%.
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 Indian Bank as a single lump sum at the start of the period would be worth ₹1,07,20,976 today (12.7% XIRR). The same money paid in monthly is worth ₹1,11,52,100.
The SIP came out ahead. That happens when the price falls during the period: later instalments buy more units for the same money, so spreading the entry out worked in the investor's favour.
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 ₹1,11,52,100 in Indian Bank. INDIANB 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.

Everything you need to know about this page and the data presented.
Investing ₹10,000 a month in Indian Bank for the last 15 years would have meant paying in ₹18,00,000 across 180 instalments. That holding would be worth about ₹1,11,52,100 today — a gain of ₹93,52,100, or 6.2× 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 Indian Bank returned an XIRR of 21.9%. 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, yes. The same ₹18,00,000 invested as a single lump sum at the start would be worth ₹1,07,20,976 today, against ₹1,11,52,100 for the monthly SIP. Spreading the entry out won here because the price fell during the period, so later instalments bought more units for the same money. 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 ₹1,11,52,100 in Indian Bank — 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 ₹55,76,050 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 ₹17,29,332 today — +188.2% on what went in, an XIRR of 45.2%. 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 Indian Bank 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.
