IPO EPS Calculator

Look up an IPO's reported earnings per share, then see how new shares issued in the IPO dilute it — pre-issue EPS vs. post-issue (diluted) EPS. Pick a live IPO to auto-fill EPS, PAT and price, or enter your own numbers.

How the IPO EPS Calculator works

The reported EPS at the top is the company's own disclosed figure — net profit for the year divided by its existing share base, exactly as shown in the DRHP's “Basis for Issue Price” table.

The pre-issue vs. post-issue section computes the dilution effect of the IPO itself: new shares issued = fresh issue amount ÷ issue price, added to the pre-issue share count to get the post-issue share count. Dividing the same PAT by a larger post-issue share count always produces a lower “diluted” EPS — that's not a red flag, it's the mechanical effect of raising fresh capital through new shares rather than debt.

Pre-issue share count is one of the least commonly disclosed figures before listing — expect this section to need manual entry from the RHP's capital structure section more often than not, even for IPOs where reported EPS and PAT auto-fill cleanly.

Frequently Asked Questions

What is the difference between reported EPS and diluted (post-issue) EPS?

Reported EPS in the DRHP is calculated on the company's pre-issue share count. Post-issue (diluted) EPS accounts for the new shares issued in the IPO, so it's always lower than pre-issue EPS for the same profit figure.

Why does EPS drop after an IPO?

The same net profit gets divided across a larger number of shares once the fresh issue shares are added to the share base — this is a mechanical dilution effect, not a sign the business is doing worse.

Where do I find pre-issue share count in the RHP?

In the 'Capital Structure' section, usually listed as the number of equity shares outstanding immediately before the issue.

Does an OFS (offer for sale) affect post-issue EPS?

No — an OFS transfers existing shares from sellers to new investors without creating new shares, so it doesn't change the total share count or dilute EPS. Only the fresh issue portion creates new shares and dilutes EPS.

Is a lower diluted EPS a bad sign for an IPO?

Not by itself. What matters is whether the capital raised through the fresh issue is used productively enough to grow future profit faster than the dilution — this calculator shows the mechanical dilution, not whether that trade-off is worth it.
