What is Equity Compensation Calculator?
▾
An equity compensation calculator helps employees and job candidates value stock options, restricted stock units (RSUs), employee stock purchase plans (ESPP), and other equity-based pay. Equity compensation is common at technology companies, startups, and increasingly at companies across all industries, yet most employees struggle to understand what their equity is actually worth. Stock options give you the right to buy company shares at a fixed strike price. If you have 10,000 options with a $5 strike price and the stock reaches $20, each option is worth $15 in intrinsic value — $150,000 total before taxes. But options can expire worthless if the stock price never exceeds the strike price, and they typically vest over four years with a one-year cliff, meaning you forfeit unvested options if you leave early. RSUs are simpler: the company promises you a certain number of shares that vest over time. When RSUs vest, you receive actual shares (or their cash equivalent) and owe ordinary income tax on their value that day. A grant of 1,000 RSUs vesting over four years delivers 250 shares per year; at $50 per share, that is $12,500 per year in pre-tax compensation. ESPP plans let employees buy company stock at a discount, typically 15 percent below market price, creating an immediate gain. The calculator models different scenarios: what your equity is worth at various stock prices, the tax implications of exercising options (ISO versus NSO treatment), the impact of dilution from future funding rounds in startups, and the expected value considering vesting schedules and probability of different price outcomes.

Formula
▾
Option intrinsic value = Max(0, Current price − Strike price) × Number of options
RSU value = Number of vested units × Current share price
ESPP gain = Shares purchased × (Market price − Purchase price)
ESPP purchase price = Market price × (1 − Discount rate) typically 85%
Vested value = Total grant × (Months vested / Total vesting months)
Post-tax value = Pre-tax value × (1 − Effective tax rate)
Diluted ownership = Your shares / (Total shares + New shares issued)Variable Legend

Worked Examples
▾
Start with realistic assumptions.
This example shows how Equity Compensation Calculator can be used as a first-pass planning tool before testing more optimistic or conservative assumptions.
Useful for stress-testing.
Conservative assumptions help users see whether the decision still looks acceptable when conditions are less favourable.
Shows best-case sensitivity.
This helps users understand how much of the outcome depends on a few optimistic inputs.
Comparisons are often more useful than isolated outputs.
Many people use Equity Compensation Calculator not for a single number, but to compare one strategy, asset, or purchase against another.
