All futures calculators
Six tools that cover the arithmetic of a futures trade end to end: what a tick is worth, how much collateral a position ties up, how many contracts your risk budget allows, whether the reward justifies the risk, what the trade actually returned after commission, and what the system's drawdown looks like over time.
How to use them together
The tools are designed to be used in sequence on a single trade. Start with the tick value calculator to establish what a tick is worth on the contract you are considering — that number is the conversion factor between the chart and your account, and it is specific to each product. Move to the margin calculator to check whether the position is fundable and how much adverse movement it can absorb before a margin call. Then use the position size calculator to derive the contract count that keeps the loss at your risk budget, and the risk reward calculator to test whether the target on offer clears the break-even win rate.
The profit and loss calculator is for after the fact: entering your actual fills and your commission to see what the trade really returned, as opposed to what the chart suggested. The drawdown calculator works at the level above individual trades, taking a sequence of results and reporting the peak-to-trough fall, the recovery return required and the longest losing streak.
A note on the example values
Each calculator ships with plausible example inputs so the page is useful before you type anything. They are illustrative specifications, not current exchange values — multipliers, tick sizes and margin requirements are set per product by each exchange and are revised from time to time. Always take the specification for the contract you actually trade from your own exchange's contract specification page.
