Formula
Stop Price = Entry Price × (1 - Risk % / 100)
Example
- Entry price: 50
- Risk %: 5
- Shares: 100
What does this mean?
- •Stop-loss limits downside when price invalidates your thesis.
- •Set levels before entering to reduce emotional decisions.
- •Reassess stops only with objective thesis updates.

Lock in discipline with deterministic stop levels.
What is a stop loss?
Turn a risk percentage into an actionable stop level and expected maximum loss in dollars. In practice, this means you can quantify stop loss using entry price, risk %, and shares without relying on hidden assumptions or black-box scoring.
Primary input set for this calculator: Entry price, Risk %, Shares.
How to calculate stop loss
- 1.Step 1: Enter entry price with the timeframe/context you want to evaluate.
- 2.Step 2: Enter risk % with the timeframe/context you want to evaluate.
- 3.Step 3: Enter shares with the timeframe/context you want to evaluate.
- 4.Step 4: Apply formula Stop Price = Entry Price × (1 - Risk % / 100).
- 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 stop 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
Stop-loss limits downside when price invalidates your thesis
Use this stop loss workflow to quantify this scenario with deterministic inputs.
Set levels before entering to reduce emotional decisions
Use this stop loss workflow to quantify this scenario with deterministic inputs.
Reassess stops only with objective thesis updates
Use this stop loss workflow to quantify this scenario with deterministic inputs.
Event reaction review
Recalculate stop loss immediately after earnings, filings, or macro headlines.
Interpretation tips
- •Re-run stop 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 stop loss calculator work?
Stop Loss Calculator is deterministic and uses only your inputs (entry price, risk %, shares). Formula: Stop Price = Entry Price × (1 - Risk % / 100).
What does this output tell me in practice?
Calculate stop-loss price and max loss from risk %. Pair this with a stop-loss and thesis review, not just return math.
Does the stop 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.
