Public float

140,000,000

Estimated float is 140,000,000 shares (70.00% of outstanding).

Shares outstanding
200,000,000
Restricted shares
60,000,000
Float % of outstanding
70.00%

Formula

Float = Shares Outstanding - Restricted / Insider Shares

Example

  • Shares outstanding: 200000000
  • Restricted / insider shares: 60000000

What does this mean?

  • •Lower float often increases volatility.
  • •Float changes after offerings, lockup expirations, and conversions.
  • •Use up-to-date filing data for precision.

What is a float?

Estimate tradable float by subtracting restricted or insider-locked shares from total outstanding shares. In practice, this means you can quantify float using shares outstanding, and restricted / insider shares without relying on hidden assumptions or black-box scoring.

Primary input set for this calculator: Shares outstanding, Restricted / insider shares.

How to calculate float

  1. 1.Step 1: Enter shares outstanding with the timeframe/context you want to evaluate.
  2. 2.Step 2: Enter restricted / insider shares with the timeframe/context you want to evaluate.
  3. 3.Step 3: Apply formula Float = Shares Outstanding - Restricted / Insider Shares.
  4. 4.Step 4: Interpret output together with risk, liquidity, and catalyst context.

Why this metric matters

This metric captures supply-side pressure from share count changes, a key input for valuation and momentum persistence.

Pair this calculator with catalyst context from headlines, filings, and options flow to avoid relying on isolated numbers.

When to use this calculator

  • ✓Before opening a new position where float impacts sizing or risk.
  • ✓After a catalyst to quantify how much conditions changed versus your baseline.
  • ✓When comparing setups across multiple tickers with one consistent formula.
  • ✓During weekly review to keep decision-making tied to measurable inputs.

Common scenarios

Use this float workflow to quantify this scenario with deterministic inputs.

Float changes after offerings, lockup expirations, and conversions

Use this float workflow to quantify this scenario with deterministic inputs.

Use up-to-date filing data for precision

Event reaction review

Recalculate float immediately after earnings, filings, or macro headlines.

Interpretation tips

  • •Re-run float whenever key inputs change materially, not only when price moves.
  • •Document assumptions so the same methodology can be repeated across watchlist names.
  • •Use this metric as one layer in the decision stack, not as a standalone trade trigger.

Data caveats

  • –Outputs are deterministic from your inputs; input quality determines output quality.
  • –This page does not auto-adjust for broker fees, taxes, or slippage unless you include them in your assumptions.
  • –Validate corporate action details, filing dates, and data freshness before acting on results.
