Understand the methodology and formulas behind our professional-grade calculator

1

Input IPO Details

Enter the IPO issue price, current GMP, number of lots, and shares per lot. These form the foundation of all calculations.

2

Calculate Expected Listing Price

The calculator adds GMP to the issue price to estimate where the stock might list on the exchange.

3

Compute Profit/Loss

Calculate gross profit by multiplying GMP with total shares, then subtract brokerage to get net profit.

4

Determine Return Percentage

Calculate the percentage return on your investment to assess the profitability of the IPO opportunity.

Core Formulas

Expected Listing Price

Listing Price = Issue Price + GMP

Total Investment

Investment = Issue Price × Total Shares

Gross Profit

Gross Profit = GMP × Total Shares

Advanced Calculations

Brokerage Cost

Brokerage = (Investment × Brokerage%) + (Expected Value × Brokerage%)

Net Profit

Net Profit = Gross Profit - Brokerage Cost

Return Percentage

Return% = (Net Profit ÷ Investment) × 100
