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.

Frequently Asked Questions

Why is my ROI lower than the first-day gain percentage?

Because you apply for more shares than you receive. The ROI is calculated on total capital committed (all shares applied Γ— offering price), not just the allocated shares' cost.

How do I find the allocation rate for an upcoming IPO?

Allocation rates are announced after the subscription period closes. Popular IPOs are highly oversubscribed β€” retail investors may receive as little as 0.1–5% of what they apply for.

Should I sell on day one or hold long-term?

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.
