How to use this calculator
Adjust the inputs to your own scenario, then review the result alongside the assumptions below. The $ symbol is a currency label; the tool does not convert exchange rates.
Worked example
A $100 budget with a 10-tick stop at $12.50 per tick and $5 cost cannot support one contract.
The formula
Contracts = floor(risk budget ÷ (stop ticks × tick value + costs)).
What the result means
Compare the output with the stated assumptions. Changing an input changes the arithmetic; it does not establish how a real trade or investment will perform.
Assumptions and limitations
Enter the correct contract tick value. Does not check margin, exchange rules, liquidity, contract expiry, or potential losses beyond a stop.
