How the IPO Listing Day Profit/Loss Calculator works

Gross listing gain is simply (listing price − issue price) × shares. But selling on the exchange triggers real transaction costs: Securities Transaction Tax (STT) at 0.1% of the sale valueon the sell side (equity delivery, unchanged as of Union Budget 2026), your broker's brokerage (flat fee or a % of turnover — this varies by broker, not fixed by regulation), and DP (depository participant) charges — typically ₹13–20 including GST, charged once per scrip per day regardless of quantity sold, again set by your broker/depository rather than a government rate.

Note: IPO allotment itself is not an exchange trade, so no STT applies on the buy/application side — only the later sell-side transaction attracts STT. For the tax on your profit itself (separate from these transaction charges), see the capital gains tax calculator.

Frequently Asked Questions

How is IPO listing day profit calculated after charges?

Net profit = (listing price × shares) − (issue price × shares) − STT (0.1% of sale value) − brokerage − DP charges. This gives your actual take-home profit, lower than the headline gross listing gain.

Is STT charged when I sell shares on listing day?

Yes — equity delivery STT is 0.1% of the sale value on the sell side, charged automatically by the exchange. It is not charged on the original IPO application/allotment, only on the sale.

What are typical brokerage and DP charges for selling IPO shares?

Brokerage varies by broker — many discount brokers charge a flat fee (e.g. ₹20) or a small % of turnover per order; it is not a fixed government rate. DP charges are usually ₹13-20 including GST, charged once per scrip per sell day irrespective of how many shares you sell.

Why is my actual profit lower than the GMP suggested?

GMP is an unofficial, informal estimate of listing gains before any transaction costs. Actual profit is reduced by STT, brokerage and DP charges, and the final listing price can also differ from the last GMP quoted before listing.

Do I pay these charges even if I hold the shares instead of selling on listing day?

No — STT, brokerage and DP charges apply only when you actually sell. If you hold, there is no transaction cost until you eventually sell, though holding period affects your capital gains tax treatment.
