Bill Gates and Paul Allen launched Microsoft in Albuquerque in 1975 to sell a BASIC interpreter for the Altair 8800, relocated to Bellevue in 1979, and settled in Redmond by 1986. Windows and Office anchored the franchise; the 1986 NASDAQ IPO minted a generation of millionaires. Under Satya Nadella, CEO since 2014, the company pivoted to Azure cloud, absorbed GitHub and LinkedIn, closed the $69B Activision Blizzard deal in 2023, and poured $13B+ into OpenAI to thread Copilot through every product surface. Market cap sits above $3T.

Equity comp at Microsoft
- Microsoft does not grant ISOs to employees; equity comp is RSUs only. The AMT-ISO calculator does not apply.
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.
- Vesting schedule: 4 years, 1-year cliff (industry standard).

If a meaningful share of your net worth sits in MSFT, concentration risk is the question. This calculator quantifies drawdown impact at 30 / 50 / 70%, and the trade-off between selling down (tax cost now) versus hedging (option premium drag), auto-filled with MSFT's option-implied volatility.
Example: 5,000 MSFT shares at $393.83 is a $1,969,150 position. A 30% drawdown costs $590,745; a 50% drawdown costs $984,575; a 70% drawdown costs $1,378,405. The calculator quantifies the trade-off between selling down (immediate capital-gains tax) and hedging (option premium drag) using MSFT's option-implied volatility and your cost basis.

Microsoft equity questions
- How much MSFT stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your MSFT position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does Microsoft grant ISOs, NSOs, or RSUs?
- Equity compensation at Microsoft typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Microsoft RSUs use double-trigger vesting?
- No. Microsoft restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
