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.

Thomas Peterffy, who helped bring computerized pricing to options floors in the 1970s, built the firm into an electronic broker serving professional traders, hedge funds, and self-directed investors across dozens of markets. Automation is the competitive position: the cost to serve an account is low enough to support pricing that full-service brokers cannot match. Margin lending and interest on customer cash produce a large share of profit, making results rate-sensitive. Account growth has come substantially from outside the United States. Headquarters are in Greenwich, Connecticut.

Equity comp at Interactive Brokers
- Interactive Brokers ties RSU vesting to the anniversary of the company's 2007 initial public offering rather than to each employee's individual grant or hire date. Awards vest in installments of roughly 10 percent per year, so a full grant can take about a decade to fully vest, far slower than the 4-year schedule common at most public companies. Because vesting is anchored to a single calendar date each year instead of a personal grant anniversary, employees hired at different times can see their RSU tranches line up on the same annual vest date.
- Vesting schedule: RSUs vest in installments of roughly 10% per year tied to the anniversary of the company's 2007 IPO rather than to an employee's individual hire or grant date, with full vesting taking about 10 years..

If you hold vested Interactive Brokers (IBKR) 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 IBKR position at $88.3 is worth $441,500. 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.

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