IPO calculators
Three free tools for the numbers behind a bid. On an IPO's page they open already filled with that IPO's figures. They answer the questions people ask while an IPO is open: what does the GMP mean in rupees, how much money will my bid block and in which category is it, and what is my chance of getting shares. Each one explains the maths it uses, shows a worked example and lists what it leaves out, and each can be filled from a current IPO.
The calculators work on numbers you enter or pick. They are for planning and learning, not forecasts, and they are not investment advice. For the data behind them, see the GMP and subscription pages.
