IPO Listing Gain Calculator
On IPO listing day, price can be anywhere from below issue price to 100%+ premium. Historically (2020-2025), mainboard IPOs on BSE/NSE have listed at an average of 15-25% above issue price. But this average hides huge variance - some IPOs list at 100%+ gain (like Zomato, Nykaa in 2021) while others list at 20-30% below issue price.

Common questions about IPO Listing Gain Calculator
Which IPOs have given the highest listing gains in India?
Some historically high listing gains: Ircon International +90% (2018), Polycab +24% (2019), Burger King +131% (2020), Zomato +53% (2021), Tatva Chintan +96% (2021), Paras Defence +185% (2021). Note: 2021 was exceptional. Most years, average listing gains are more modest (10-20%). Always check GMP (Grey Market Premium) as an informal indicator before applying.
What is the GMP and how reliable is it?
Grey Market Premium (GMP) is the unofficial premium at which IPO shares trade before listing. It gives an informal indication of market sentiment. A GMP of Rs 200 on a Rs 1,000 issue price suggests 20% listing premium. GMP is not reliable - it can change drastically the day before listing based on market conditions. Treat GMP as one data point, not a guarantee.
Should I always subscribe and sell on listing day?
Listing day selling (flipping) works well in bull markets. In bear markets, many IPOs list below issue price. A more selective strategy: apply only for IPOs of quality businesses at reasonable valuations, hold for 6-12 months for full value unlock. Studies show IPOs of profitable companies with strong fundamentals significantly outperform market over 2-3 years versus subscribed-and-sold immediately.
