Ten calculators for the numbers traders work out every day: how big to trade, what a move is worth and what you need to break even. Each one shows the formula behind its answer.

After the trade
A calculator checks one trade. A journal checks all of them.
Most calculators here work on one trade. What decides your results is what happens across all of them: the risk you actually took, the R you actually got, and what fees and swap took out.
- Planned next to actual — the risk and R you planned beside the ones you got
- Every contract in dollars — futures priced with each contract's point value
- Fees and swap out — every result is net
A trading journal puts the numbers from these calculators next to what really happened.
