fin.employee-stock-options Calculator
Calculates the net after-tax gain from exercising employee stock options (ISOs or NSOs) from grant price, current price, and tax rate. NSO spread is taxed as ordinary income on exercise; ISO spread is an AMT preference item — the tax treatment fundamentally changes the optimal exercise strategy.
