How to use this

What it tells you: how much of your total profit came from your single best day (or trade), and whether that breaks the firm's consistency rule.

1. Firm / Plan (top of the page): fills in the firm's limit and shows its rule wording above.
2. Daily P&L list: type each day's profit or loss in its own box (Day 1, Day 2 and so on), with a minus for a loss. Profits show green and losses red. Use + Add day for more days, × to remove a day, and Clear all to start again. Or switch to Total + best day and type the two numbers.
3. Limit (%): the firm's maximum share for one day. Change it to test another rule.
4. Measured on: best day or best single trade, whichever the firm's rule uses. If you pick best single trade, the boxes become Trade 1, Trade 2 and so on.
5. Profit target (optional): shows how far you are towards it.

Reading the result: the big % is your best day's share of total profit. The bar is green when you're well inside the limit, amber when you're past 80% of it, and red when you're over. ✓ Within the limit also shows the most your next day could make and still stay within the limit (that day's profit counts towards the total too). ✕ Over the limit shows roughly how much more profit you need, without beating your best day, to get back under.

How it's worked out: Share = best day ÷ total profit × 100. Most your next day can make = limit × total ÷ (1 − limit). If you're over: extra profit needed = best day ÷ limit − total profit.

Watch out: each firm checks consistency using its own wording (best day or best trade, and whether it applies in the challenge, at payout, or both). Read the rule shown above the calculator and follow that.

What it tells you: how much more you can lose today, and in total, before you hit the firm's loss limits.

1. Starting balance: your account size.
2. Max loss type: Static means the floor stays fixed. Trailing means the floor moves up as your equity reaches new highs. EOD trailing is the same, but it only uses end-of-day balances.
3. Daily loss limit (%) and Max loss (%): the firm's limits.
4. Daily limit based on: whether the daily % is taken from your starting balance or from today's start.
5. Today's start: your balance or equity (whichever was higher) when the day reset.
6. Current balance and Current equity: equity includes profit or loss on open trades.
7. Highest equity / EOD balance so far (trailing only): your peak. The tick box stops the trailing floor rising above your starting balance, as many firms do.

Reading the result: the first box shows the daily loss you have left and the level your equity must stay above today. The second shows the max loss you have left and the floor. Green means you have room. Amber means less than 30% of the smaller limit is left. Red means you're at or past the limit. The line underneath shows your real room, which is the smaller of the two.

How it's worked out: Daily floor = today's start − daily %. Daily left = lower of balance and equity − daily floor. Static floor = starting balance − max %. Trailing floor = highest point − max % of starting balance. Max left = equity − floor.

Watch out: trailing and static limits behave very differently, so pick the type that matches the firm's wording. The daily loss resets at the time the firm states, and firms differ on whether open (floating) losses count.

How to use this

What it tells you: the trade size (in lots) that loses your chosen amount if your stop loss is hit.

1. Instrument: the pair, gold or silver.
2. Account currency: the currency your account is in.
3. Account balance.
4. Risk: either a % of your balance or a fixed amount of money.
5. Stop: the distance to your stop loss, in pips or as a price distance.
6. 1 … = ? …: the exchange rate used to convert pip value into your account currency. It fills in automatically, and you can type your broker's price instead.
7. Plan max risk per trade / max lots (optional): the firm's caps, auto-filled when we found them.

Reading the result: the big number is the lot size, with units (or ounces) next to it. Below it you'll see the money at risk, the value of 1 pip on 1 lot in your currency, and the loss per lot if the stop is hit. If a cap is set, a green box means you're within it and a red box means you're over (the risk-cap box also shows the largest size that fits).

How it's worked out: Lots = money you risk ÷ (stop in pips × pip value per lot). A pip is 0.0001 (0.01 for JPY pairs), and 1 lot = 100,000 units, so 1 pip = 10 (or 1,000 for JPY pairs) of the second currency, converted at the rate shown.

Watch out: rates are ECB reference rates (updated daily, not live tick prices), so type in your broker's rate if you want it exact, and round down to your broker's lot step (usually 0.01). Gold: here 1 pip = $0.01 and 1 lot = 100 oz, so 1 pip = $1 per lot. If your broker calls $0.10 a pip, enter the stop as a price distance instead.

How to use this

What it tells you: roughly what you keep from a payout.

1. Profit on funded account: the profit you're withdrawing.
2. Your profit split (%): your share. It fills in from the plan, and you can change it.
3. Fees / withdrawal costs: anything taken off.
4. Challenge fee refunded with this payout: put 0 if there isn't one.

Reading the result: the big number is your estimated take-home, and the line below shows the sum. It doesn't include tax or currency conversion.

How it's worked out: Take-home = profit × your split % − fees + refund.

Watch out: splits can differ by plan, by add-on and over time (some firms raise them after several payouts). Check the split wording shown above the calculator.

How to use this

What it tells you: on average, what it costs to get one funded account once you count failed attempts.

1. Challenge price: fills in from the plan and size.
2. Your assumed pass rate (%): your own guess at how often you'd pass.
3. Refund when you pass (money): the fee returned when you pass or get your first payout (0 if none).
4. Retry discount (%): any discount on later attempts.

Reading the result: the big number is the expected cost per funded account. The line below shows the average number of attempts, the total spent, the refund, and the chance of failing 5 times in a row.

How it's worked out: Attempts = 100 ÷ pass rate. Spent = price + (attempts − 1) × price × (1 − discount). Cost = spent − refund. Chance of failing 5 in a row = (1 − pass rate)⁵.

Watch out: the pass rate is your own estimate, not a firm figure. It's an average, and real results can be much worse. Some firms only refund at the first payout, not when you pass.
