Consistency Score Calculator

Work out your consistency score in seconds. Enter the profit or loss for each of your trading days and the calculator shows your score using the City Traders Imperium formula, alongside the best day rule most other prop firms use, so you can see exactly where you stand before you request a scale up.

Both Formulas Compared
1
Enter every trading day. Add the closed profit or loss for each day you traded. Losing days go in as negative numbers. Days with no trades are left out.
2
Read your score. The score is your single biggest day, win or loss, as a share of everything you made and lost. Lower means steadier.
3
Plan your next days. The calculator tells you how much more trading activity you need before your biggest day stops dominating the account.

All figures are in US dollars. CTI uses 20% for scaling, so leave it there for a CTI account, or change it to match whatever rule your firm applies. Your account size does not change the score, it shows your biggest day as a share of the account and sizes the example below.

Worked example, shown aboveOn a $100,000 account with days of $4,000, -$2,000, $3,000, $4,000, $2,000, -$2,000 and -$4,000, the biggest single day is $4,000 and the absolute profit and loss of all seven days adds up to $21,000. That gives a CTI consistency score of 4,000 divided by 21,000, which is 19.05%. Edit the days on the left to use your own figures.

Other prop firms use consistency to decide if you pass. We never do. At CTI it only affects scaling an Instant Funding or Direct Funding account, where you show you can manage risk before we size you up. That is why our score counts losing days too, not just winners.
Two Different Rules

The CTI Formula Against The Industry Formula

City Traders Imperium

Biggest Day Against All Activity

Absolute value of your most profitable or losing day, divided by the sum of the absolute profit and loss of every trading day.
0%

Your score on your own numbers.

This looks at everything you did, wins and losses together, so a single outsized day stands out whichever direction it went. A trader who blew up on one day and recovered on another is not consistent, and this formula says so.

Most Other Prop Firms

Best Day Against Net Profit

Your best winning day, divided by your total net profit.
0%

The same days under the industry rule.

Because the bottom of this sum is net profit, a big losing day shrinks the denominator and pushes the score up, and the rule breaks down completely if the account is at breakeven or in the red. It also ignores loss size entirely.

Both figures above are calculated from the days you entered in the calculator.

How To Read It

What The Consistency Score Actually Tells You

One Day Should Not Carry The Account

The score answers a single question: how much of everything you did came down to one day. A trader whose best day is a fifth of their total activity has a process that repeats. A trader whose best day is half of it has one good trade and a lot of noise around it, and that is not something a firm can size up safely.

Losses Count, Not Just Wins

Using the absolute value means a heavy losing day damages your score exactly as much as an outsized winning day. That is deliberate. Risk taken is risk taken, and a trader who can lose a large amount in one session can lose it again on a bigger account.

More Days Move It More Than Big Days

You cannot delete a day you already traded, so the only way down is to add more normal ones. To sit at 20% your total activity needs to be five times your biggest day. The calculator works out the gap for you so you know roughly how much more trading it takes.

Common Questions

Consistency Score Questions Answered

Does the consistency score stop me passing or getting paid?

No. The 20% figure is a scaling measure, not a pass or payout condition. It applies when scaling an Instant Funding or Direct Funding account, and it has no bearing on passing a challenge, on your drawdown limits, or on receiving a payout. You are not failed for a high score, it simply means the account is not ready to be sized up yet. Always check the current terms of your specific programme, since rules can be updated.

How is the consistency score calculated at CTI?

Take the absolute value of your most profitable or losing day, whichever is larger, and divide it by the sum of the absolute profit and loss of every trading day. If your biggest day was a $4,000 loss and your days add up to $21,000 of absolute profit and loss, the score is 4,000 divided by 21,000, which is 19.05%.

What consistency score do I need?

A score of 20% or below is the mark to aim for, and it applies to scaling an Instant Funding or Direct Funding account rather than to passing a challenge. Keeping a single day under a fifth of your total activity shows the firm that your results come from a repeatable process rather than one outlier, which is what makes larger capital sensible.

Why does CTI use absolute values instead of net profit?

Because net profit hides risk. A trader can make $10,000 on one day, lose $6,000 across the rest, and still look fine on a rule that only compares the best day to the net figure. Using the absolute value of every day shows the full size of what was risked, and it keeps working even when the account is flat or negative, which the net profit version cannot do.

How do I lower my consistency score?

Add more trading days at your normal size. The past cannot be changed, so the score falls as ordinary days accumulate around your biggest one. Reaching 20% means getting your total absolute profit and loss to five times your largest day. Trading larger to catch up does the opposite, because a new outsized day simply replaces the old one.

Do losing days count as trading days?

Yes. Every day you closed a position counts, win or lose, and both go into the total using their absolute value. Days where you did not trade at all are ignored completely, so sitting out does not help or hurt your score.

Is a lower consistency score always better?

For this measure, yes, a lower number means no single day dominated. It is worth remembering that the score says nothing about whether you were profitable. A trader can have an excellent consistency score and still lose money, which is why it is read next to your profit, drawdown and win rate rather than on its own.

Does this calculator work for other prop firms?

Yes. Enter your days once and you get both figures: the CTI score and the best day against net profit rule that most other firms apply. Check your own firm’s threshold, since the common limits sit anywhere between 20% and 50% and each firm defines the sum slightly differently.

Please note: This calculator is an independent tool for planning and education. It works out your score from the daily figures you enter, so it is only as accurate as those figures, and it does not read your live account. Your official consistency score is the one shown on your CTI dashboard, and programme rules and thresholds can change, so always check the terms that apply to your account. Nothing here is financial or investment advice.
