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 — 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 × Allocation rate%. Opening price = Offering price × (1 + First-day gain%). Profit = (Opening price - Offering price) × Allocated shares. ROI = Profit ÷ (Offering price × Applied shares) × 100.
Disclaimer
First-day IPO performance is unpredictable. Some IPOs decline below offering price on day one. Use this tool for scenario planning only — not as a guarantee of returns.
Frequently Asked Questions
Because you apply for more shares than you receive. The ROI is calculated on total capital committed (all shares applied × offering price), not just the allocated shares' cost.
Allocation rates are announced after the subscription period closes. Popular IPOs are highly oversubscribed — retail investors may receive as little as 0.1–5% of what they apply for.
First-day selling locks in the IPO pop but may miss long-term gains. Holding carries the risk of price decline. Consider your investment horizon and the company's fundamentals.
