Prop firm drawdown calculator

Every prop firm account has a floor: a balance it must stay above. Enter your account's numbers to find the floor and how much room you have left under the three common drawdown rules.

Your floor

$22,500

Room left above the floor: $3,000
Room as a share of your balance: 11.8%

Floors are usually checked against your equity, including open positions at their current price, not just your cash balance.

The three drawdown rules

Static drawdown

Floor = starting balance × (1 − drawdown). It never moves. On a $25,000 account with a 10% drawdown, the floor is $22,500 however well you trade. Lenium evaluations use a 10% static floor.

Trailing drawdown, as a share of your highest balance

Floor = highest balance × (1 − drawdown). It rises with every new high and never falls. Reach $27,000 and a 10% floor moves up to $24,300. Lenium funded accounts trail 10% and Instant accounts 6% this way.

Trailing drawdown, as a fixed dollar amount

Floor = highest balance − (starting balance × drawdown). The gap stays the same number of dollars. Reach $27,000 with a $2,500 drawdown and the floor is $24,500. This is common at futures prop firms, often with the floor stopping at the starting balance.

Floors on a $25,000 account with a 10% drawdown
Highest balance	Static	Trailing (% of peak)	Trailing (fixed $)
$25,000	$22,500	$22,500	$22,500
$26,000	$22,500	$23,400	$23,500
$27,000	$22,500	$24,300	$24,500
$30,000	$22,500	$27,000	$27,500

Why the floor matters more on prediction markets

When a market resolves, the price jumps straight to $1 or $0, so a position can lose its whole cost at once and a stop order can't cut that loss halfway. Size each position so that losing all of it still leaves you above the floor; the Kelly calculatorincludes a position cap for that. Full details of Lenium's floors are on the rules page.

Questions

What happens if I hit the floor?: On most prop firms, including Lenium, the account ends as soon as your equity touches or drops below the floor. In an evaluation that means a fail; on a funded account the account closes.
Does a trailing floor ever stop rising?: It depends on the firm. At Lenium the trailing floor follows your highest balance up with every new high. Some futures prop firms stop moving it once it reaches the starting balance. Check your firm's rules.
Is static or trailing drawdown easier?: Static is easier to keep: once you are in profit, your room only grows. A trailing floor takes back room every time you set a new high. See trailing vs. static drawdown, with examples.
Is the floor checked on my balance or my equity?: Usually on equity: your cash plus open positions at their current price. A position that is losing on paper counts against you before you close it.
