IPO Calculator

IPO stands for Initial Public Offering. It's when a private company sells shares to the public for the first time on a stock exchange. Investors can participate and potentially profit if the stock rises after listing.

You register through your stockbroker app during the book-building or subscription period. You specify how many lots you want and deposit the funds. Shares are allocated based on demand — you may receive fewer lots than requested (allotment).

Allotment is the number of lots you actually receive. When an IPO is oversubscribed (more demand than supply), shares are distributed proportionally or by lottery. You may get 0 lots even if you applied.

No. While many IPOs on IDX hit ARA on listing day, some drop below the IPO price immediately. Research the company's fundamentals, underwriter reputation, and market conditions before participating.

Buy fees are charged when you subscribe to the IPO. Sell fees apply when you sell the shares on the market. Both are typically between 0.1%–0.3% depending on your broker, and directly affect your net profit.

Underwriters with strong track records tend to produce IPOs that perform well at listing. Checking an underwriter's history of ARA on listing day is a common strategy among retail investors in Indonesia.

This varies greatly. Some IPOs hit ARA for 1–3 consecutive days, others for 10+ days. It depends on supply (float), demand, sector popularity, and market sentiment. This calculator lets you simulate profit at each ARA level.
