Formula

Unrealized Gain/Loss = (Current Price - Avg Cost) × Shares Held

Example

  • Current price: 73.8
  • Average cost: 68.4
  • Shares held: 420

What does this mean?

  • •Unrealized P/L changes as market price updates.
  • •Useful for monitoring risk and exit planning.
  • •Not locked in until shares are sold.

What is a unrealized gain/loss?

Use this deterministic unrealized gain/loss calculator to estimate current mark-to-market P/L on open positions. In practice, this means you can quantify unrealized gain/loss using current price, average cost, and shares held without relying on hidden assumptions or black-box scoring.

Primary input set for this calculator: Current price, Average cost, Shares held.

How to calculate unrealized gain/loss

  1. 1.Step 1: Enter current price with the timeframe/context you want to evaluate.
  2. 2.Step 2: Enter average cost with the timeframe/context you want to evaluate.
  3. 3.Step 3: Enter shares held with the timeframe/context you want to evaluate.
  4. 4.Step 4: Apply formula Unrealized Gain/Loss = (Current Price - Avg Cost) × Shares Held.
  5. 5.Step 5: Interpret output together with risk, liquidity, and catalyst context.

Why this metric matters

This metric turns trade assumptions into explicit numbers for sizing, entry/exit planning, and portfolio discipline.

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 unrealized gain/loss 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

Unrealized P/L changes as market price updates

Use this unrealized gain/loss workflow to quantify this scenario with deterministic inputs.

Useful for monitoring risk and exit planning

Use this unrealized gain/loss workflow to quantify this scenario with deterministic inputs.

Not locked in until shares are sold

Event reaction review

Recalculate unrealized gain/loss immediately after earnings, filings, or macro headlines.

Interpretation tips

  • •Re-run unrealized gain/loss 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.

FAQ

How does the unrealized gain/loss calculator work?

Unrealized Gain/Loss Calculator is deterministic and uses only your inputs (current price, average cost, shares held). Formula: Unrealized Gain/Loss = (Current Price - Avg Cost) × Shares Held.

What does this output tell me in practice?

Calculate current open profit or loss on held shares. Pair this with a stop-loss and thesis review, not just return math.

Does the unrealized gain/loss calculator use real-time market feeds?

No. This page does not auto-pull live data. You control all inputs and can rerun instantly as market conditions change.

Can I use this result directly for trading decisions?

Use it as a planning layer. Combine with position sizing, liquidity, and catalyst context before any execution.
