The calculation, explained

How to use the crypto position size calculator

For Bitcoin, Ethereum or another crypto asset, enter prices in the same quote currency as your balance. EDGE Size estimates coin quantity for spot buys and linear futures longs or shorts.

  1. Enter your account balance and your chosen risk percentage.
  2. Add the planned entry and stop prices. For a long, the stop is below entry; for a short, it is above entry.
  3. Add fees and exchange limits if known, then calculate. Check the estimated loss, position value and funds required before using the result.

Position size formula and worked example

Ignoring fees: risk budget = account balance × risk percentage ÷ 100. Coin quantity = risk budget ÷ the absolute difference between entry and stop.

Example: a 1,000 USDT balance with a 1% risk budget gives 10 USDT of planned risk. At an entry of 100 USDT and a stop of 95 USDT, the distance is 5 USDT per coin. 10 ÷ 5 = 2 coins, with a position value of 200 USDT.

Illustrative numbers only, not recommended settings. Fees reduce the quantity that fits the same risk budget. Quantity steps are rounded down; exchange minimums and available funds still need checking.

Does leverage change my position size?

For the same risk budget, entry, stop and fees, this calculator keeps the coin quantity unchanged. Leverage changes estimated initial margin for linear futures. It does not remove price risk; liquidation, maintenance margin and exchange rules require separate checks.

Is my stop-loss the maximum I can lose?

No. The estimate assumes execution at the entered prices. Slippage, gaps, funding, borrowing costs and liquidation can change the outcome. A stop order does not guarantee the exit price or cap the loss.

Can I use this for Bitcoin and other cryptocurrencies?

Yes, when the entered market fits the supported spot or linear-futures model. Use consistent quote-currency units and the correct exchange fees, quantity step and minimum order size. Inverse contracts, options and currency conversion are not supported.
