IPO Returns Calculator
Calculate IPO listing gains and later profit from your allotted shares. See the gross return formulas, a worked example, and limits of the tax estimate.
This IPO returns calculator compares your issue price with the listing price and a current or exit price. Enter the shares actually allotted to calculate profit, loss and percentage return before charges and tax. The price fields are manual, so the result depends on the prices you supply. Listing gain, later price movement and cash received after selling are different amounts.
The Hold/Sell Decision label uses fixed return bands. It does not assess the company or your circumstances. The Tax Implication display is also a rough estimate with important limits explained below. Neither label is a recommendation or a completed tax calculation.
Start with your allotment, then choose a comparison price
An IPO, or initial public offering, is the share issue you are measuring. For this calculation, the starting cost is the final price you paid for your allotted shares. Check your allotment record rather than assuming that the application price or the number of shares requested became your investment.
- IPO Issue Price: enter the actual per-share allotment cost. If you received a category discount, use the price you actually paid when measuring your own return.
- Listing Price (Optional): enter the opening price you want to compare with. Although the field says optional, a blank field can use a built-in price, so fill it explicitly for a meaningful listing comparison.
- Current/Exit Price: use a current quote to value an unsold holding, or the actual sale price to review an exit. An assumed future price creates only a scenario.
- Number of Shares Allotted: enter shares, rather than applications or lots. The form does not estimate whether an application will receive allotment.
- Holding Period (Days): follow the form convention of days from listing to exit. The form asks for a day for a listing-day sale; this convention does not establish the legal tax holding period.
- ASBA Blocked Period (Days): enter the period used for the calculator's capital-commitment comparison. ASBA means Application Supported by Blocked Amount, where application money is held in your bank account.
If you are still planning an application, the IPO investment amount calculator addresses the application amount. Return on an actual allotment starts with the shares you received. Do not multiply the return here by every lot you applied for.
Listing return and post-listing return use different starting prices
Amount Invested is issue price multiplied by allotted shares. Listing Day Profit subtracts the issue price from the listing price and multiplies the difference by those shares. Listing Day Return % divides the per-share difference by the issue price and expresses it as a percentage.
Current Value uses the Current/Exit Price. Current Profit/Loss compares that value with Amount Invested. Current Return % uses the issue price as its starting point, so it measures the whole move since allotment.
Post-Listing Gain measures only the move from listing price to Current/Exit Price. Post-Listing % divides that move by the listing price. The percentage therefore has a different base from Current Return %. Adding the listing and post-listing percentages would mix those bases. Their rupee gains, using the same share count, can be added.
An opening price is a reference point. If your sale executed at a different price, only the execution price describes your sale proceeds. For shares still held, Current Profit/Loss is an unrealised change in value, meaning a gain or loss before a sale.
Worked example: a listing gain followed by a lower exit
These are made-up prices and quantities, not a past IPO: issue price ₹200, listing price ₹250, exit price ₹240 and 50 allotted shares. Assume Holding Period (Days) is 66 and ASBA Blocked Period (Days) is 7. Enter every field explicitly to avoid default values.
| Result | Arithmetic | Example output |
|---|---|---|
| Amount Invested | ₹200 × 50 | ₹10,000 |
| Listing Day Profit | (₹250 - ₹200) × 50 | ₹2,500 |
| Listing Day Return % | (250 - 200) / 200 × 100 | 25% |
| Current Value | ₹240 × 50 | ₹12,000 |
| Current Profit/Loss | (₹240 - ₹200) × 50 | ₹2,000 |
| Current Return % | (240 - 200) / 200 × 100 | 20% |
| Post-Listing Gain | (₹240 - ₹250) × 50 | -₹500 |
| Post-Listing % | (240 - 250) / 250 × 100 | -4% |
The example still shows a gain against issue cost, even though the price fell after listing. The ₹2,500 listing reference gain plus the -₹500 later move equals the ₹2,000 gross exit gain. This does not tell you what an alternative sale would actually have achieved, because it assumes execution at the stated listing price.
Why annualising a brief holding can mislead
Annualized Return % scales the gross price return over a year. This implementation adds Holding Period (Days) and ASBA Blocked Period (Days) before doing that calculation. It treats the result as a capital-commitment window, rather than using the post-listing holding alone.
In the made-up example, the combined period is 66 + 7 = 73 days. Its calculation is ((1 + 0.20) raised to (365 / 73) - 1) × 100 = 148.832%, displayed as 148.8%. That is a mathematical extrapolation. It is not the cash gain on this trade, a forecast, or evidence that similar IPO opportunities can be repeated throughout a year.
SEBI explains that ASBA application money remains in the bank account until allotment, when the requisite amount is debited. SBI further specifies that blocked funds continue earning interest if held in an interest-bearing account. The calculator does not add that bank interest or handle a larger application amount separately from the allotted investment. Its annualised figure is therefore a simplified comparison.
Gross profit is different from your after-cost result
The main gain fields measure the difference between share prices. There are no inputs here for your brokerage, depository charges for selling shares, other transaction charges or funding expenses. A positive Current Profit/Loss is therefore not a statement of the amount left after all costs.
Keep the actual sale record and charge statement alongside this estimate. A partial exit also needs care: a single share count and exit price cannot describe every sale in a holding sold at different prices. Review each sale separately or calculate a consistent weighted sale price outside this form, then reconcile the remaining shares.
The total trading cost calculator addresses a different question: how trading costs affect a result. Check that its chosen market and inputs match your transaction before comparing the outputs.
What the tax display cannot establish
The Income Tax Department's share-sale guidance uses a holding period exceeding 12 months for listed shares to qualify as long term. This tool uses a fixed day cutoff and counts its Holding Period field from listing. Do not use that shortcut to establish the legal acquisition date or the treatment of a sale near the boundary.
The estimate also lacks your other gains, losses, income and available annual relief. It cannot know whether an annual allowance has already been used elsewhere. Its surcharge logic does not assess your total income. Have a CA, a qualified tax accountant, check the applicable law and your complete records for the sale period. The printed estimate should not be copied into a tax return.
