Perps account calculator
How much can your account trade?
Choose a market, account size and leverage. See your buying power, perp size and futures equivalent.
Use the leverage allowed for the market you trade. A firm's maximum can differ by market and plan.

Equivalent exposure at the same reference price. Actual futures prices can differ; fractional contracts are comparison values.
A 1% price move at this size means $5,000 in profit or loss.
Assumes the full account is available as margin. Position caps, existing trades, fees and drawdown rules can reduce usable size. Buying power is exposure, not your loss allowance.
Same account. Different leverage.
At 12×
$120,000
Enter a positive balance and reference price.
At 50×
$500,000
Enter a positive balance and reference price.
50× gives you 4.17 times the buying power of 12× on the same balance.
Account size × leverage = buying power
A $5,000 account at 50× allows $250,000 of exposure. The same account at 12× allows $60,000. This is why the leverage available on your market matters as much as the account size.
