Calculator on your own inputs. Not advice. Your account size stays in this browser and the coach never sees it.
How it's calculated
Amount at risk = account size × risk per trade ÷ 100. Position size in units = amount at risk ÷ the distance between entry and stop-loss. Position value = units × entry.
For forex pairs, metals, index CFDs and oil, fill in the instrument: the calculator also shows lots (units ÷ the contract size of one lot) and, for forex, the stop distance in pips. When the price is in another currency than your account, it converts it, or asks you for the exchange rate.
Example: an account of 5,000 with 1% risk puts 50 at risk. With an entry at 100 and a stop-loss at 98 the distance is 2, so the size is 25 units. If the stop is hit, the loss is about 50, before fees and slippage.

Questions
Which contract size does the calculator use?
The usual default per instrument: 100,000 units for a forex lot, 100 ounces for gold, and so on. Brokers differ, especially for indices and oil, so you can type over it.
Are fees and slippage included?
No. The calculator measures the distance to your stop. Fees, spread, swap and slippage come on top, so a real loss at the stop can be slightly bigger.
