Prop Firm Challenge Calculator

Pass your prop-firm challenge with the numbers in front of you

Funded-trader (prop firm) challenges give you a demo account and ask you to hit a profit target without breaching two loss limits: a maximum overall loss and a maximum daily loss. Break either and the challenge ends. This calculator turns the firm's percentages into the actual dollar levels you need to watch, plus your progress toward the target.

What it shows

• Target balance — the account value you must reach to pass.
• Profit still needed — how far you are from that target.
• Overall loss floor — the balance you must never close below for the whole challenge, and your current buffer above it.
• Today's loss floor — the level that would breach the daily limit, based on your current balance.

The discipline it encourages

Most challenges are failed on the loss rules, not the profit target. Knowing your exact floors lets you size positions so a string of losers can't blow the daily or overall limit. Many traders stop for the day once they're within a small buffer of the daily floor.

FAQ

Is this prop-firm calculator free to use?

Yes, it's completely free with no sign-up, and you can run the numbers for as many accounts and challenges as you like.

Is my account data private?

Yes. Your balance, targets, and limits are calculated in your browser and never sent to a server or shared with any prop firm, so your figures stay on your device.

Does it work for any prop firm's challenge?

Yes. You enter the firm's own percentages for the profit target, maximum overall loss, and maximum daily loss, so it adapts to any firm's rules. Just confirm whether each limit is measured on balance or equity, since firms differ.

Is the daily loss limit based on my starting balance or current balance?

It depends on the firm. Many measure the daily loss from your start-of-day balance or equity, while some include open trades. This tool calculates today's loss floor from the balance you enter, so set it to match how your firm tracks the daily limit.

Why do most traders fail on the loss rules instead of the target?

Hitting a profit target is achievable with patience, but a single oversized position or a bad day can breach a daily or overall loss limit and end the challenge instantly. Knowing your exact loss floors lets you size positions so a losing streak can't blow either limit.

Educational tool only — not financial advice. Daily-loss rules vary (some measure from start-of-day balance or equity, some include open trades); always confirm your firm's exact rules.
