This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for India change on a published schedule; the effective date is shown on every rule-based tool.
How this is calculated
An option is the right to buy at the strike price, so it is worth the spread and nothing more. Vesting decides how much of the grant you actually hold: with a one year cliff nothing vests at all until that date, and then the first year lands in one piece. Exercising costs real money up front, the strike times the number of options, and in most jurisdictions the spread is taxed as income at that moment even though nothing has been sold. That combination, cash out and tax due on an illiquid asset, is what makes exercising a private company option a genuine risk rather than a windfall.
Worked examples
Each of these is asserted on every build. If a change to the engine ever moved one of these answers, the build would fail before the page could print it.

Open this exampleMethod and limits
What it assumes
- Monthly vesting after the cliff, which is the common schedule but not the only one.
- A single tax rate at exercise, where real treatment varies by scheme and jurisdiction.
What it deliberately does not model
- A private company share price is a valuation, not a market price, and the two differ substantially.
- Liquidation preferences can leave common shares worth far less than a headline valuation implies.
- Tax treatment of options is scheme-specific and the rate here is a placeholder for your own.

Frequently asked questions
- Why is my option worth nothing?
- Because the current price is at or below the strike. An option is the right to buy at the strike, so there is no value in exercising until the price is above it.
- Why would exercising cost me money?
- Because you buy the shares at the strike price, and in most places the spread is taxed as income at that moment. You can owe cash tax on shares you cannot sell.
