Where are stop-loss and take-profit prices for chosen percentages?

This calculation converts percentage distances into price levels around an entry. It is a placement tool for arithmetic consistency, not an assessment of volatility or an instruction to use those levels.

Offsets above and below entry

Stop price = Entry × (1 − Stop% ÷ 100)Target price = Entry × (1 + Target% ÷ 100)Max loss = (Entry − Stop price) × SharesMax gain = (Target price − Entry) × Shares

Placing two mechanical levels

The default example starts from one entry price and applies the entered downside and upside percentages. It reports both levels and the monetary distances from entry.

Illustrative inputs; currency amounts below use USD. Rates and prices are assumptions, not live quotes.

Entry price
$12.21
Shares
100
Stop loss
6%
Take profit
18%

Step-by-step calculation

  1. Long-position stop = 12.21 × (1 − 6 ÷ 100) = 11.4774.
  2. Target = 12.21 × (1 + 18 ÷ 100) = 14.4078.
  3. Multiply each price move by 100 units: planned loss -73.26, planned gain 219.78. Gaps, fees and slippage are excluded.

Intermediate figures are rounded for reading. Results use the full calculation precision.

Take profit price$14.41
Stop loss price$11.48
Maximum gain$219.78
Maximum loss-$73.26

Price distance is not account risk

For a long position, the stop sits below entry and the target above it. Changing either percentage affects only its corresponding level and also changes the implied reward-to-risk relationship.

Execution effects the levels cannot predict

Do not confuse a percentage of entry with a percentage of account equity. Position size determines how a price move translates into account loss or gain.

  • The levels are calculated for the position direction represented by the config.
  • Percentages are measured from the entry price.
  • Gaps, slippage, fees and order execution rules are excluded.

Quick answers

Frequently asked questions

How do I calculate a stop-loss price from a percentage?

The calculator multiplies entry by one minus the stop percentage divided by 100.

How is the take-profit price calculated?

Entry is multiplied by one plus the target percentage divided by 100.

Are trading fees included in the maximum gain and loss?

No. The formula uses only entry, target, stop and share quantity.
