Prop Firm Drawdown Calculator

The prop firm drawdown calculator above tells you two prices you must never touch: the daily floor and the maximum floor. It also shows how many dollars sit between your current equity and each one, and flags which floor is closer. Presets cover 68 plans across 27 crypto prop firms, including the reset time and reference each firm uses.

How to use the prop firm drawdown calculator

1. Choose a firm and plan from the preset menu, or switch to manual and type the rule yourself.
2. Enter the account size the firm funded.
3. Confirm the daily limit, what it is measured from (start-of-day balance or equity at the reset) and the reset time. HyroTrader, HyperPNL and FTMO, for instance, read equity at the reset.
4. Confirm how the overall limit behaves (fixed, trailing intraday, trailing on closed balance, or trailing until it locks) and its percentage.
5. Type today's figures: balance at the last reset, your highest balance where a floor trails, and current equity.

The result shows both floors, the room under each and a sentence naming the limit that binds.

The formula behind each floor

The daily reference resets at a fixed clock time, which ranges by firm between midnight UTC and 17:00 in New York. A trailing floor only ever rises. Lock levels differ: E8 One locks after a 4% gain, Fundedbit's 1-step and Crypto Fund Trader's 1-Phase after 6%, and Propr's Classic 2-Step after 8%.

Worked example: a $50,000 Fundedbit 1-step

Fundedbit's 1-step uses a 4% daily limit from the balance at 00:15 UTC and a 6% maximum that follows the high-water mark until a 6% gain, then freezes at the original account size.

The daily floor binds today, so $1,748 is the real loss budget. Notice what the trailing floor has already done: on day one it sat at $47,000, and a $1,800 run-up has lifted it by $1,692. Once the high reaches $53,000 the floor stops at $50,000 for good. On a static plan such as HyroTrader's Two-Step, the same $50,000 account keeps its maximum floor at $45,000 no matter how the week goes.

On a trailing plan, profit you give back is room you lose permanently. On a static plan, profit adds room.

Common mistakes

• Holding through the reset on an equity-based reference. An open loss at the reset lowers tomorrow's starting point.
• Forgetting funding payments. Perpetual funding is charged every eight hours on Bybit and hourly on Hyperliquid and comes straight out of equity.
• Ignoring fees. Firms such as Breakout and Bitfunded deduct 0.04% per side from the balance.
• Missing daylight-saving shifts at firms whose reset follows New York or Central European time.
