Prop Firm Daily Loss Limit Calculator

TL;DR: A prop firm daily loss limit is a session-specific boundary, but the reference balance, measured equity, included costs, reset time, and consequence vary by program. Use the calculator below only with values copied from your program’s current rules. For example, a $100,000 reference, $3,000 limit, -$1,000 realized P/L, -$500 open P/L, and $100 in costs produces -$1,600 measured P/L, $1,400 remaining allowance, and a $97,000 illustrative equity floor. Reaching zero in this calculator means the entered threshold is reached or exceeded; it does not determine whether a firm records a pause, liquidation, or failed account.

A prop firm daily loss limit controls how much loss an account may record during a defined trading session. There is no safe universal formula. One program may use current equity and include open P/L, swaps, and commissions, while another may apply a fixed risk setting or a temporary pause.

Use the current rule page and account dashboard as the controlling references. This guide is document-based research, not first-hand account testing or personalized trading advice.

How a Prop Firm Daily Loss Limit Works

Start by identifying four items in the current program rules:

1. The reference balance or equity used for the session.
2. The daily loss amount or percentage.
3. The P/L and costs included in the measurement.
4. The reset time and result at the threshold.

A daily limit is separate from a firm’s overall drawdown rule. Read the BestProps prop firm drawdown guide for the difference between static, trailing, and end-of-day drawdown. The tighter remaining boundary can become relevant first.

Prop Firm Daily Loss Limit Formula

The calculator uses reader-entered rules, not firm presets:

• Current measured P/L = realized P/L + open P/L – costs.
• Remaining allowance = daily loss amount + current measured P/L.
• Illustrative equity floor = reference balance – daily loss amount.

Losses should be entered as negative P/L. Costs are entered as a positive number and subtracted once. A zero or negative remaining allowance means the entered threshold has been reached or exceeded. It is not a universal breach ruling because firms define enforcement differently.

Use the Daily Loss Limit Calculator

Enter the reference and rule values from the program documentation. Choose a fixed dollar limit or use the percentage helper. The tool does not recommend a firm, account size, position, stop, or risk percentage.

Daily Loss Calculator Test Cases

• A $100,000 reference, $3,000 limit, -$1,000 realized P/L, -$500 open P/L, and $100 costs returns -$1,600 measured P/L, $1,400 remaining, and a $97,000 floor.
• A $50,000 reference, 2% helper, -$250 realized P/L, $0 open P/L, and $50 costs returns a $1,000 limit, -$300 measured P/L, $700 remaining, and a $49,000 floor.
• A $100,000 reference, $3,000 limit, and -$3,100 measured P/L returns -$100 remaining and a threshold-exceeded label.

Daily Loss Rules From Official Sources

The examples below show why the calculator has no built-in firm preset. Each statement is scoped to the named program and was checked against the linked official source on July 31, 2026.

FTMO Daily Loss Rules

For the FTMO Challenge 2-Step and the later FTMO Account 2-Step, FTMO states that the Maximum Daily Loss Amount is 5% of Initial Simulated Capital. It recalculates the limit at 00:00 CE(S)T by subtracting that fixed amount from the account balance recorded at the reset. FTMO defines the monitored equity as balance plus open-position P/L, plus or minus swaps, minus commissions. Equity below the calculated limit violates the rule. See the official FTMO Trading Objectives.

Topstep Daily Loss Rules

Topstep states that its Daily Loss Limit is optional for the Trading Combine and Express Funded Account and automatic for the Live Funded Account. For the Trading Combine and Express Funded Account, a trigger during the 5:00 PM to 3:10 PM CT session flattens open positions, cancels pending orders, and blocks new trades until 5:00 PM CT the next session. Topstep says this trigger is a forced break, not a funding-rule violation. See the official Topstep Daily Loss Limit guide.

Tradeify Daily Loss Rules

Tradeify states that the Daily Loss Limit applies to Growth, Lightning, and Select Daily Funded accounts, while Select Flex accounts do not have it and 25K Lightning accounts are excluded. Reaching the limit pauses trading until the next market session after 6:00 PM ET; the account stays active if the separate Max Trailing Drawdown has not been reached. Tradeify also warns that the Daily Loss Limit is not a guaranteed stop because losses may exceed it before protection triggers. See the official Tradeify Daily Loss Limit rules.

Balance, Equity, and Costs in a Daily Limit

Balance generally reflects closed trading results. Equity can also reflect open P/L, which means a temporary loss may count before a position closes when the program monitors equity in real time.

Costs require the same care. A rule may include commissions, swaps, or other charges. This calculator subtracts one positive cost input. Do not enter a negative cost or subtract the same charge again inside realized P/L.

When a Daily Loss Limit Resets

The reset follows the firm's stated session boundary, not necessarily the trader's local midnight. Record the stated timezone, convert it to local time, and account for daylight-saving changes. Confirm how open positions and costs spanning the reset are treated.

The reset can also change the reference balance. FTMO's documented 2-Step method, for example, records a new balance at 00:00 CE(S)T while keeping the daily loss amount tied to Initial Simulated Capital. Other programs use different methods.

Daily Loss Pause vs Account Failure

Do not assume every daily threshold has the same outcome. Topstep describes its covered Daily Loss Limit as a forced session break rather than a violation. Tradeify describes its Daily Loss Limit as a soft pause but warns that the separate Max Trailing Drawdown can fail the account first. FTMO treats equity below its calculated Maximum Daily Loss Limit as a rule violation.

That difference is why the calculator reports only the arithmetic state of the values entered. The official program rules determine the account consequence.

Daily Loss Limit Checklist

• Which program and stage does the rule cover?
• What balance or equity creates today's reference?
• Is the limit a fixed amount or a percentage?
• Does open P/L count in real time?
• Which commissions, swaps, or fees count?
• What is the reset time and timezone?
• Does touching the threshold count, or only moving below it?
• Does the result cause liquidation, a session pause, or account failure?
• Is a separate drawdown boundary closer?
• Where does the dashboard show the live threshold?

Prop Firm Daily Loss Limit FAQs

Can an Open Trade Reach the Daily Limit?

Yes, when the program monitors equity and includes open P/L. FTMO's documented formula is one current example. Other programs may measure the account differently.

Does the Daily Loss Limit Replace Drawdown?

No. Daily loss and maximum drawdown are separate controls. A program can apply both, and the overall drawdown boundary may be closer than the daily limit.

Can Profit Change the Next Daily Limit?

It depends on the reference formula. A reset-balance method may change the next floor after profit or loss, while a fixed-reference method may not. Check the current program rules and dashboard.

Is the Calculator a Breach Checker?

No. It reproduces the arithmetic from the values entered. It cannot know whether a firm counts a threshold touch, uses another equity definition, delays a system action, or applies a separate failure rule.

Always recheck the official program page before relying on a daily loss calculation. Rules, plan scope, amounts, and session times can change.
