How to Use the IPO Return Estimator
IPO investing involves applying for shares at the offering price and selling on listing day at a profit if the stock opens higher. The challenge is that you rarely get all shares you request β allocation depends on demand.
Enter the offering price, shares applied, allocation rate, and expected first-day gain percentage. The calculator shows your expected allocation, profit, and return on the capital you committed.
How It's Calculated
Allocated shares = Applied shares Γ Allocation rate%. Opening price = Offering price Γ (1 + First-day gain%). Profit = (Opening price - Offering price) Γ Allocated shares. ROI = Profit Γ· (Offering price Γ Applied shares) Γ 100.
Disclaimer
First-day IPO performance is unpredictable. Some IPOs decline below offering price on day one. Use this tool for scenario planning only β not as a guarantee of returns.
