One stack per ticker (current-employer RSUs, prior-employer holdings, index fund, etc.). Each stack has its own current price, growth assumption, and cost-basis lots.

Estimates only. Not financial advice.
Lock-in-now is deterministic (0%). Plans that wait depend on future prices; risk is near-zero when inventory comfortably exceeds the goal. Volatility: each stack's option-implied vol if a ticker is set, otherwise 30%. Lognormal model; real markets have fatter tails.

Al Shugart and Finis Conner founded the company in 1979 and shipped one of the first 5.25-inch hard drives for personal computers. Consolidation left two makers of spinning disks, Seagate and Western Digital, both now selling primarily to cloud providers rather than PC builders. Heat-assisted magnetic recording is the technology bet for raising capacity per platter, and Mozaic drives carry it to market. The company is incorporated in Ireland with principal United States operations in Fremont, California, and revenue moves with hyperscaler storage cycles.

If you hold vested Seagate (STX) shares and need a set amount of cash by a date (a house down payment, tuition, a sabbatical, a business buy-in), the question is which lots to sell and in which tax years to keep the most after tax. This calculator builds the minimum-tax sell schedule across your lots, accounting for federal long-term capital gains, the net investment income tax, and your state.

Seagate equity questions
- How much STX stock do I sell to fund a goal without overpaying tax?
- It depends on your cost basis, your target amount and date, and how the sale spreads across tax years. Selling vested STX shares triggers long-term capital-gains tax, plus the 3.8% net investment income tax and state tax above certain income, and bunching a large sale into one year can push the gain into a higher bracket. The calculator above builds the minimum-tax sell schedule across your lots to net your target amount by your date.
- Does Seagate grant ISOs, NSOs, or RSUs?
- Equity compensation at Seagate typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Seagate RSUs use double-trigger vesting?
- No. Seagate 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.
