Realized Gain/Loss Calculator
Calculate realized profit or loss from sold shares.
Use this deterministic realized gain/loss calculator to quantify profit from completed sales using cost basis per share.
Results
Realized gain/loss
+$1,350.00
Realized result on sold shares is +$1,350.00.
- Sell price
- $73.80
- Cost basis/share
- $68.40
- Shares sold
- 250.0000
- Realized P/L
- +$1,350.00
Formula
Realized Gain/Loss = (Sell Price - Cost Basis Per Share) × Shares Sold
Example
- Sell price: 73.8
- Cost basis per share: 68.4
- Shares sold: 250
What does this mean?
- •Realized P/L is closed and no longer market-dependent.
- •Use broker lot method (FIFO/LIFO/specific lot) for tax accuracy.
- •Exclude unsettled fees unless explicitly included.

What is a realized gain/loss?
Use this deterministic realized gain/loss calculator to quantify profit from completed sales using cost basis per share. In practice, this means you can quantify realized gain/loss using sell price, cost basis per share, and shares sold without relying on hidden assumptions or black-box scoring.
Primary input set for this calculator: Sell price, Cost basis per share, Shares sold.
How to calculate realized gain/loss
- 1.Step 1: Enter sell price with the timeframe/context you want to evaluate.
- 2.Step 2: Enter cost basis per share with the timeframe/context you want to evaluate.
- 3.Step 3: Enter shares sold with the timeframe/context you want to evaluate.
- 4.Step 4: Apply formula Realized Gain/Loss = (Sell Price - Cost Basis Per Share) × Shares Sold.
- 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 realized 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
Realized P/L is closed and no longer market-dependent
Use this realized gain/loss workflow to quantify this scenario with deterministic inputs.
Use broker lot method (FIFO/LIFO/specific lot) for tax accuracy
Use this realized gain/loss workflow to quantify this scenario with deterministic inputs.
Exclude unsettled fees unless explicitly included
Use this realized gain/loss workflow to quantify this scenario with deterministic inputs.
Event reaction review
Recalculate realized gain/loss immediately after earnings, filings, or macro headlines.
Interpretation tips
- •Re-run realized 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 realized gain/loss calculator work?
Realized Gain/Loss Calculator is deterministic and uses only your inputs (sell price, cost basis per share, shares sold). Formula: Realized Gain/Loss = (Sell Price - Cost Basis Per Share) × Shares Sold.
What does this output tell me in practice?
Calculate realized profit or loss from sold shares. Pair this with a stop-loss and thesis review, not just return math.
Does the realized 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.
