IPO Profit Calculator – IPO Return & GMP Calculator

At listing, profit per lot is roughly GMP × lot size. Pick an IPO above or enter the numbers to see it for 1 to 10 lots. It is an estimate only; the real listing price can be higher or lower, and charges and tax apply.

Yes. The calculator works for any Indian mainboard or SME IPO. SME lot sizes are larger, so check the minimum investment as well.

Estimated listing price = issue price + GMP. Profit = GMP × lot size × number of lots, and return % = GMP ÷ issue price × 100. For example, a ₹500 issue with ₹150 GMP and a 30-share lot gives about ₹4,500 profit per lot (30%).

Yes. Tap the 1, 2, 3, 5 or 10 lot chips, use the plus and minus buttons, or type any number of lots. A table also shows profit for each common lot count.
