Every futures contract moves in its own increments and each one is worth a fixed amount. Get those two numbers right and risk is simple arithmetic; get them wrong and the position is nothing like the size you think.
Money moved equals ticks multiplied by tick value multiplied by contracts, where ticks are the price distance divided by the contract's tick size. The E-mini S&P moves in 0.25 increments worth $12.50 each, and its micro is a tenth of that. Confusing a mini with a micro is a tenfold sizing error and the most common futures mistake.

Money = (move ÷ tick size) × tick value × contracts. Specifications change — confirm tick size and value on the exchange's own contract page before trading.
Tick size is the smallest price increment a contract trades in. Tick value is what one tick is worth per contract. Money moved = ticks × tick value × contracts, and the number of ticks in a move is the price distance divided by the tick size.
The calculator has the common contracts pre-filled and a custom option for anything else. Specifications do change, so confirm them on the exchange's own contract page before trading.

Divide your risk budget by it for the contract count - the same shape as the lot size and stock calculations. With futures the answer is often "less than one contract", which is a real answer: it means the trade is too big for the account unless a micro contract exists.
The smallest price increment the contract trades in. Tick value is what that increment is worth per contract.
Ticks moved x tick value x number of contracts. The calculator converts a price distance into ticks for you.
A point is a full unit of price; a tick is the minimum increment. Many index contracts have four ticks per point.
No. Exchanges change specifications, so the values here are a starting point and the exchange's own contract page is the authority.
