Pair-specific pip values — approximate rates for estimation
Position Size
0.40 Lots
Risking $200.00 (2.0% of account) on EUR/USD
Pip value per lot: $10.00 · Pip size: 0.0001
Risk Amount
$200.00
SL Distance
50 pips
Pip Value/Lot
$10.00
Formula
Position Size = (Account Balance × Risk%) / (SL Distance in Pips × Pip Value per Lot)
= ($10,000 × 2%) / (50 pips × $10.00/pip) = 0.40 lots
Step 1
Type your total account balance and choose your base currency. The calculator supports USD, EUR, and GBP.
Step 2
Use the slider or quick presets to set how much of your account you are willing to risk. Most professionals use 0.5% to 2%.
Step 3
Input the price you plan to enter at and where your stop loss will be. The tool calculates the pip distance automatically.
Step 4
See the exact number of lots to trade, the dollar amount at risk, stop loss distance in pips, and risk-reward ratio.
This calculator sizes one trade at a time from numbers you enter by hand. SignalFloor Pro's position sizing is different: it runs automatically on every signal from the providers you follow, pre-calculating a lot size tailored to your account so you don't reach for a calculator mid-trade.
