How to use this calculator
Each step names a control you will find on screen above.
- Read both companies
Two real Indian businesses are shown with their share prices. One is priced far lower than the other.
- Guess which is bigger, before revealing
Commit to an answer. The tool works by catching you out, and it cannot do that if you skip ahead.
- Reveal
The market capitalisations appear. Note the size of the gap between your intuition and the answer.
- Look at the share-count column
This is the whole explanation. Price × shares = market cap, and share count varies by orders of magnitude between companies.

Where this is taught
A calculator gives you a number. These explain what the number means and when it misleads you.
- Market Basics12 minHow a mutual fund actually worksNAV, cut-off times, exit loads, direct versus regular, and the expense ratio that quietly removes a fifth of your final corpus.
- Fundamental Analysis10 minYour share of the business: share count, EPS and what the whole company costsA share price on its own says nothing about how large a company is or how much of it you own. The share count is what turns a price into a claim.
- Market Basics8 minWhat is a share, really?A share is not a lottery ticket or a number on a screen. It is a legal slice of a business, and everything else follows from that.
- Fundamental Analysis11 minMarket capitalisation and enterprise value: two ways to say what a company costsThe price of the equity is not the price of the business. Debt and cash sit between the two, and every multiple you use depends on which one you picked.
- Market Basics11 minMutual funds, index funds and ETFsThe alternative to picking stocks yourself — how each vehicle works, what it costs, and the honest case for using one even after learning all this.
