| Company Valuation | Total Shares | Granted Shares | Vested % | Pool Increase % | Funding Dilution % |
|---|---|---|---|---|---|
| 5,000,000 | 1,000,000 | 25,000 | 50% | 5% | 10% |
| 12,000,000 | 2,400,000 | 60,000 | 75% | 3% | 8% |
| 20,000,000 | 4,000,000 | 100,000 | 100% | 4% | 12% |
Ownership Percentage = (Employee Granted Shares ÷ Total Fully Diluted Shares) × 100
Vested Shares = Employee Granted Shares × (Vested Percentage ÷ 100)
Vested Ownership Percentage = (Vested Shares ÷ Total Fully Diluted Shares) × 100
Post Pool Shares = Total Shares × (1 + Future Option Pool Increase ÷ 100)
Post Funding Shares = Post Pool Shares × (1 + New Funding Dilution ÷ 100)
Post Dilution Ownership = (Employee Granted Shares ÷ Post Funding Shares) × 100
Current Equity Value = Employee Granted Shares × Current Implied Share Price
Exercise Cost = Employee Granted Shares × Exercise Price
Paper Gain Before Tax = Current Equity Value − Exercise Cost
Estimated Net Gain = Paper Gain Before Tax × (1 − Tax Rate ÷ 100)
Business equity percentage helps HR teams explain ownership clearly. It shows how much of a company a grant represents. This matters during hiring, promotion, and retention planning. A strong calculator makes compensation conversations more practical and transparent.
Equity should usually be measured on a fully diluted basis. This includes common shares, options, and similar rights. That method gives a more realistic ownership view. It helps employees compare grants fairly across roles and funding stages.
A grant may look large at first glance. However, vested equity shows what is already earned. HR and People Ops teams often need both values. One supports offer design. The other supports current reward discussions and retention reviews.
Future option pools and investment rounds can reduce ownership percentages. This does not always mean the grant becomes worse. Company value may rise at the same time. Still, dilution modeling is essential for realistic planning and responsible communication.
This business equity percentage calculator connects grant size, vested status, and dilution assumptions. It also estimates current value, exercise cost, and potential gain. These outputs help HR leaders build compensation packages with better context and cleaner documentation.
Recruiters, founders, finance partners, and people teams can use this page during offer planning. It is also useful when comparing refresh grants. A repeatable ownership method reduces confusion. It helps teams align on fair and explainable equity decisions.
It shows the share of the business represented by a grant. The percentage is usually based on fully diluted shares, not only currently issued common shares.
Fully diluted shares include options and similar rights. This gives a more realistic ownership percentage and makes offer comparisons much more accurate.
Vested ownership reflects the portion already earned under the vesting schedule. It is often lower than the total granted ownership percentage.
Dilution increases the total share base. That reduces the ownership percentage linked to the same grant, even when the number of granted shares stays unchanged.
No. A lower percentage can still be worth more if company valuation rises significantly. Ownership percentage and company value should be reviewed together.
Yes. It helps compare grant sizes, explain ownership clearly, and model likely dilution. That supports cleaner compensation discussions with candidates and managers.
Exercise cost is the amount needed to purchase option shares. It equals granted shares multiplied by the exercise price per share.
No. It is a simplified estimate using your tax input. Actual taxes depend on jurisdiction, timing, plan rules, and personal circumstances.
