Prop Firm Drawdown Calculator

Type in a sequence of trade P&Ls and see how your trailing drawdown line moves. Good for sanity-checking how close your funded account really is to breaching.

Apex 50k = $2,500. Topstep 50k = $2,000. Tradeify 50k = $2,500.
For TopStep-style: floor stops moving once balance + buffer is reached.

How the trailing drawdown works

Trailing drawdown follows your highest account equity. When your balance makes a new high, the floor (your minimum allowed balance) moves up to maintain the buffer distance. Once set, the floor never retreats. A trade that spikes equity then closes flat permanently locks in the cushion between the old floor and the new one.

End-of-day (EOD) drawdown only updates the floor at session close, so intraday spikes don’t permanently move the floor. This is softer on scalpers and mean-revert traders. Frozen drawdown (TopStep-style) stops moving the floor once your equity crosses a preset threshold.

Why this matters

Two traders can both end a month at +$2,000 realized. One never saw equity above the entry balance + $2,000 and has full buffer intact. The other ran equity up to +$5,000 unrealized multiple times before closing, and has now locked in $3,000 of cushion permanently. Same headline P&L, radically different account survival odds going forward.

FAQ

Which prop firms use trailing drawdown?
Apex, Tradeify, and TakeProfitTrader use trailing on funded accounts. TopStep uses a trailing variant that freezes once equity hits a threshold. FTMO uses fixed (non-trailing) drawdown on their standard plan.
Does the floor move on unrealized profit?
On most trailing firms, yes — intraday unrealized highs count. That’s why scalpers who run up +$3,000 then close +$500 can end a day “technically profitable” while having eaten cushion they can’t recover.
How do I avoid locking in cushion?
Take profit at your pre-defined target. Don’t let winners drift into equity highs without a plan. On trailing-drawdown firms, leaving profits on the table is often the right call if the alternative is inflating your floor.
