Price Per Share Calculator
Enter company value (or market cap) and shares outstanding to calculate the implied price per share. Optionally add shares owned or an ownership percentage to see the dollar value of your stake — useful for investor updates, cap table reviews, startup equity planning, and market cap comparisons.
Enter your share valuation inputs
Two required inputs (company value + shares outstanding) give you the implied share price. Add optional inputs to calculate the value of a specific stake.

What this calculator does
This calculator divides total company value (or market cap) by shares outstanding to produce the implied price per share. Enter shares owned or an ownership percentage to also see the dollar value of that stake and the implied number of shares represented by a given percentage.
Price per share formula
The formula is mechanical — the quality of the result depends entirely on how reliable the company value input is. For public companies, market cap is observable. For startups, it is typically the last-round post-money valuation.
How to use this calculator
- Enter the total company value or market capitalization.
- Enter total shares outstanding — use basic shares or fully diluted depending on your analysis.
- Optionally enter shares owned to see the dollar value of that holding at the implied price.
- Optionally enter an ownership percentage to see the implied share count and stake value.
- Click Calculate to see price per share and all derived metrics.
Example calculations
Public company preset — $25M company value · 5M shares outstanding:
- PPS = $25,000,000 ÷ 5,000,000 = $5.00 per share
- Value of 1,000 shares = 1,000 × $5.00 = $5,000
- 0.02% ownership = 0.0002 × 5,000,000 = 1,000 implied shares
Startup equity preset — $12M post-money · 8M shares:
- PPS = $12,000,000 ÷ 8,000,000 = $1.50 per share
- 25,000 shares = 25,000 × $1.50 = $37,500 stake value
- 1.25% ownership = 0.0125 × $12M = $150,000 stake value
Micro-cap preset — $3.75M · 15M shares:
- PPS = $3,750,000 ÷ 15,000,000 = $0.2500 per share
- Very low share price does not mean small company — depends entirely on share count structure.
Common mistakes
- Using an outdated or wrong share count. After stock splits, new share issuances, or buybacks, the outstanding share count changes. Always use the current figure from the latest filing or cap table.
- Confusing a higher share price with a more valuable company. A $500 share price can represent a smaller company than a $5 share price if share counts differ by 100×. Market cap is what determines total value, not share price alone.
- Using basic shares when fully diluted is needed. For startup cap table work and dilution analysis, use fully diluted shares (including options and warrants). For current market cap derivation, basic shares outstanding is typically used.
- Mixing pre-money and post-money valuations. In startup contexts, post-money valuation is the figure after new investment. Using pre-money with new investor share counts overstates PPS.
- Ignoring liquidation preferences on preferred stock. In a private company exit, preferred shareholders may have preferential claims before common shareholders receive value. The calculator uses total company value — which may overstate common share value in liquidation scenarios.
FAQ
What is the price per share formula?
Price Per Share = Company Value (or Market Cap) ÷ Shares Outstanding. Value of Stake = Shares Owned × Price Per Share. Implied Shares = (Ownership% ÷ 100) × Shares Outstanding. Ownership Value = (Ownership% ÷ 100) × Company Value.
Is market cap the same as company value?
For public companies, market capitalization (share price × shares outstanding) is the market value of equity. It is not the same as enterprise value, which also accounts for debt and cash. For simple PPS calculations, market cap is the standard input. For private companies, the relevant figure is typically the most recent post-money valuation from a funding round.
Should I use basic or fully diluted shares?
Use fully diluted shares (including options, warrants, and convertibles) when analyzing dilution or startup equity. Use basic shares outstanding for simple market cap to share price derivations for public companies. The difference can be significant — options can represent 10–20% of total equity in early-stage startups.
Why can two companies have very different share prices but similar market caps?
Because share price depends entirely on how many shares exist. A company worth $10M with 1M shares has a $10 PPS. The same company with 100M shares has a $0.10 PPS. Share price alone says nothing about company size or value — market cap is the correct comparison metric.
Can I use this for startup cap table analysis?
Yes — enter the post-money valuation and total fully diluted share count to see the implied PPS. Then enter specific share counts or ownership percentages to value individual stakes. Keep in mind that startup valuations are not observable market prices and may not reflect liquidation value due to preferred stock preferences.
