What the stop-loss and take-profit calculator does
Every trade plan needs two exit prices before the entry: where you accept that you are wrong (the stop-loss) and where you take profit. The calculator turns a stop distance — in pips or points, as a percentage of the entry price, or as the dollar amount you are willing to lose — into an exact stop-loss price, then places take-profit levels at multiples of that risk: 1R, 2R, 3R or any multiple you choose. It works for longs and shorts on forex, gold, indices, crypto and stocks.
How to use it
- Choose the direction: long (buy) or short (sell).
- Choose how you express the stop: pips/points, percent or dollar risk.
- Enter the entry price and the pip or point size of the instrument: 0.0001 for most forex pairs, 0.01 for yen pairs, 0.1 for gold at most brokers, 1 for many indices. It also turns distances into pips.
- Enter the stop distance and the position size in units. One standard forex lot is 100,000 units, and one lot of gold is usually 100 ounces. Units turn price distances into dollars and are required for the dollar-risk mode.
- Enter the take-profit as an R multiple: 2 places the target twice as far from the entry as the stop.
The formula
stop distance d = pips × pip size
= entry × percent ÷ 100
= dollar risk ÷ units
long: stop = entry − d target at kR = entry + k × d
short: stop = entry + d target at kR = entry − k × d
risk ($) = units × d
reward ($) = units × k × d
break-even win rate = 1 ÷ (1 + k)
Dollar amounts assume the instrument is quoted in US dollars (EUR/USD, XAU/USD, BTC/USD, US indices). For pairs quoted in another currency, convert with the pip value calculator.
Worked example
Forex long in pips. Buy EUR/USD at 1.1600 with a 25-pip stop and 100,000 units (one lot):
- d = 25 × 0.0001 = 0.0025, so the stop-loss is 1.1575, 0.22% below the entry
- Risk at the stop: 100,000 × 0.0025 = $250
- Targets: 1R at 1.1625, 2R at 1.1650, 3R at 1.1675
- Reward at 2R: $500; break-even win rate at 2R: 1 ÷ 3 = 33.3%
Gold short in percent. Sell gold at 2,650.00 with a 0.8% stop: d = 2,650 × 0.008 = 21.20, so the stop is at 2,671.20, the 2R target at 2,607.60 and the 3R target at 2,586.40.
Bitcoin long from a dollar risk. Buy 0.5 BTC at 60,000 and accept a $150 loss: d = 150 ÷ 0.5 = 300, so the stop is at 59,700 (0.5% below the entry) and the 2R target at 60,600.
Where to put the stop first
The calculator does the arithmetic; the stop itself should come from the chart and the instrument's volatility, not from the amount you would like to lose. A sound order of work:
- Place the stop where the trade idea is proven wrong — beyond a swing high or low, or at a multiple of the ATR (the ATR stop-loss calculator helps).
- Measure that distance here and read the R targets.
- Size the position so that the stop distance costs your planned risk — the position size calculator gives the lots.
- Check that the targets are realistic. If 2R lies beyond a level the market rarely clears, the setup may not be worth taking.
Using several R targets
The 1R, 2R and 3R rows also work as a scaling-out plan. Close a third of the position at each level and, if all three are reached, the trade averages (1 + 2 + 3) ÷ 3 = 2R. If the price turns after 1R and comes back to the original stop, the result is (1 − 1 − 1) ÷ 3 = −0.33R; move the stop to the entry once 1R is reached and the same trade ends at (1 + 0 + 0) ÷ 3 = +0.33R instead. Scaling out smooths results but caps the winners, so judge it on a journal of trades, not on a single outcome.
Common mistakes
- Choosing the stop from the dollar amount alone. A $100 stop on a large position can sit inside normal noise. Use the dollar-risk mode to translate a budget, not to decide where the market proves you wrong.
- Forgetting the spread. Stops on longs trigger at the bid and stops on shorts at the ask, so a spread that widens around news or at the daily rollover can hit a stop the chart never seems to touch. Leave a small buffer.
- Moving the stop after entry. Widening it to avoid a loss changes the trade's R after the fact and distorts every statistic you keep.
- Mixing up pip sizes. A 25-pip stop is 0.0025 on EUR/USD, 0.25 on USD/JPY and usually 2.50 on gold. Check the contract specification.
- Reading R targets as forecasts. 2R and 3R are reference levels to judge a setup with the risk/reward calculator, not prices the market owes you.
