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.

Founded in 1984 and transformed by the 2019 purchase of First Data, the company processes card transactions for merchants and runs the core banking systems that thousands of financial institutions depend on. Both halves are infrastructure: replacing a bank's core processing system is a multi-year project institutions avoid, and merchant acquiring earns a fraction of every transaction processed. The Clover point-of-sale platform moved the company into selling directly to small businesses. Payment volume growth rather than pricing drives revenue. Headquarters are in Milwaukee.

Equity comp at Fiserv
- Fiserv requires double trigger vesting for equity granted after 2019: unvested RSUs, stock options, and performance share units accelerate only if a change of control is followed by a qualifying termination (or death/disability) within two years, not on the change of control alone. This replaced prior Key Executive Employment and Severance Agreements (KEESAs), terminated in 2021, which had allowed single trigger vesting and walk away rights on a change of control. Standard RSU grants vest ratably, with 33% vesting on each of the first three anniversaries of the grant date; some historical award agreements instead began vesting on the second anniversary of grant.
- RSUs use double-trigger vesting. Two things must both happen before the shares are yours: (1) the normal time-based vesting completes, and (2) the company has a liquidity event (an IPO or an acquisition). Until both happen, you do not yet own the shares and you do not owe tax on them.

If you hold vested Fiserv (FISV) 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 FISV position at $44.36 is worth $221,800. 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.

Fiserv equity questions
- How much FISV 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 FISV 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 Fiserv grant ISOs, NSOs, or RSUs?
- Equity compensation at Fiserv typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Fiserv RSUs use double-trigger vesting?
- Yes. Fiserv restricted stock units (RSUs) vest only when two things both happen: the time-based schedule completes, and the company has a liquidity event such as an initial public offering (IPO) or an acquisition. Until both occur you do not own the shares and owe no tax on them.
