ESOP Value Calculator
ESOPs are taxed twice, and the first hit lands before you've sold anything: at exercise, the gap between fair market value and your strike price is a 'perquisite' taxed as salary at your slab rate. Only later, when you sell, does capital gains tax apply on appreciation beyond that FMV.
Enter your options, strike, the current FMV, how much has vested and your slab rate. The calculator shows the perquisite, the tax on it, the full cash outlay to exercise (strike + tax), and the net value you'd hold.
How it works
- Perquisite = (FMV at exercise − strike price) × vested options exercised — taxed as salary income at your slab (+4% cess), usually via TDS.
- Total cash needed = exercise cost (strike × options) + perquisite tax.
- On a later sale, capital gains = sale price − FMV at exercise (the FMV becomes your cost basis).
Frequently asked questions
How exactly are ESOPs taxed in India?
Stage 1 (exercise): FMV minus strike is a salary perquisite at your slab rate — payable even though you received shares, not cash. Stage 2 (sale): sale price minus that FMV is a capital gain — for listed shares, 12.5% LTCG beyond 12 months / 20% STCG; for unlisted, LTCG needs 24 months and slab rates apply short-term.
I work at a startup — can the exercise tax be deferred?
If your employer is an eligible startup (Section 80-IAC registered), the perquisite TDS defers to the earliest of: 5 years* from allotment, the day you leave, or the day you sell (*within specified timelines). It is a deferral, not a waiver — and only a small minority of startups have the 80-IAC certificate, so ask HR specifically.
When is exercising a bad idea?
When the perquisite tax is large, immediate, and the shares are illiquid — you pay real cash today for paper you may not be able to sell (private company, lock-ins). Underwater options (FMV below strike) are worth zero to exercise. The calculator's 'total cash needed' row is the number to respect.
Who sets the FMV for the perquisite?
For listed companies, the exchange price on the exercise date. For unlisted companies, a merchant banker's valuation report (rule 3(8) of the IT Rules) — typically refreshed periodically, and often materially different from the last funding round's price.
