Inputs
Your equity
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.

Plan
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.

The flash-memory business was separated from Western Digital in early 2025, returning the SanDisk name to public markets as a standalone maker of NAND memory and storage products. Memory is a commodity with a brutal cycle: supply is added in large indivisible increments, and prices fall until capacity discipline returns. The joint-venture fabrication arrangement with Kioxia shares the capital burden but also ties output decisions to a partner. Retail-branded cards and drives carry better margins than raw component sales. Headquarters are in Milpitas, California.

Equity comp at SanDisk
- SanDisk was spun off from Western Digital on February 21, 2025, becoming an independent public company. As part of the separation, outstanding equity awards were converted rather than cashed out. Continuing SanDisk employees below Vice President level had their outstanding Western Digital RSUs (restricted stock units, which convert to actual shares once time-based vesting conditions are met) converted one-for-one into equivalent SanDisk RSUs. Employees at Vice President level and above had their RSUs and PSUs (performance stock units, which vest based on performance targets in addition to time) split: converted into a mix of both SanDisk and Western Digital awards. Original vesting schedules were preserved through the conversion; the spin-off itself did not trigger vesting or a cash-out.

If you hold vested SanDisk (SNDK) 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.
Example: a 5,000-share SNDK position at $1,719.99 is worth $8,599,950. Say you need $150,000 of it for a house down payment by next spring. Selling enough shares all in one tax year can push the gain into the higher long-term capital-gains bracket and trigger the 3.8% net investment income tax; spreading the sale across two tax years often nets more. The calculator above finds the minimum-tax sell schedule across your specific lots, basis, goal, and date.

SanDisk equity questions
- How much SNDK 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 SNDK 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 SanDisk grant ISOs, NSOs, or RSUs?
- Equity compensation at SanDisk typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
