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.

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.

3M traces to 1902, when five businessmen in Two Harbors, Minnesota founded the Minnesota Mining and Manufacturing Company to mine corundum for sandpaper; finding a low-grade deposit instead, they pivoted to manufacturing abrasives. Headquartered in Maplewood, Minnesota, the company now manufactures industrial, safety, transportation and electronics, and consumer products, including Scotch tape and Post-it notes. On April 1, 2024, 3M completed a spin-off, separating its health care unit into an independent public company called Solventum, which carried roughly a quarter of prior-year revenue. 2024 net sales totaled $24.6 billion, with about 61,500 employees.

Equity comp at 3M
- 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.

If you hold vested 3M (MMM) 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 MMM position at $164.15 is worth $820,750. 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.

3M equity questions
- How much MMM 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 MMM 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 3M grant ISOs, NSOs, or RSUs?
- Equity compensation at 3M typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do 3M RSUs use double-trigger vesting?
- No. 3M 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.
