This tool provides estimates based on a generic linear model. Contract specifications differ by exchange; confirm actual counts against the exchange.
What is a contract quantity calculator?
For USDT-margined linear contracts, margin × leverage gives notional, then dividing by price gives the number of contracts.
Real contracts have specific face values (e.g. 0.001 BTC per contract). This tool uses a generic linear model (1 contract = 1 base coin) and is an estimate.
How to use
- Enter the entry price.
- Enter available initial margin and leverage.
- Click Calculate to see notional and the number of contracts.
Formula
- Notional = Initial Margin × Leverage
- Contracts = Notional ÷ Entry Price (1 contract = 1 base coin)
Example
BTC at 20,000 with 200 margin and 10x: notional 2,000 → 0.1 contracts.
The same margin at 20x: notional 4,000 → 0.2 contracts.
FAQ
How do real exchanges convert contracts?
Actual counts depend on contract face value and multiplier (e.g. 0.001 BTC per contract). Check the exchange spec; this tool is a linear estimate.
Do maintenance margin and liquidation limit the count?
They reduce usable margin in practice. This tool only estimates what initial margin can support.
