Each risk rule has a weight that will help you calibrate the impact of each rule on the total score used to determine the risk level.

For every rule, then, you can choose a value between 1-20.

This value will be the score of the rule if it fails.

**1**is the minimum weight that can be assigned to safety rules. The closer to 1, the less it will affect the risk level for the order.**20**is the maximum weight that can be assigned to a safety rule. The closer to 20, the more it will affect the risk level for the order.**10**is the**default value**and stands for average risk.

Whenever a rule fails, it scores the value of the weight.

## How is the risk calculated?

The risk is calculated as a percentage value resulting from the following formula:

Risk Percentage = **( score of all failed rules / maximum obtainable score ) * 100**

**Score of all failed rules**: this is the sum of the weight of all failed rules.**Maximum obtainable score**: this is the default weight (10) by the number of rules enabled.

**Example:**

- “Enable first order check” with a weight of 5;
- “Enable suspicious email domain check” with a weight of 15;
- “Enable unsafe country check” with a weight of 20.

**The maximum obtainable score** is the default weight (10) times the number of rules, which is 3, so will be **30**.

CASE 1: If all rules fail, the score of all failed rules will be 5 + 15 + 20 = **40**.

So, in the formula: (40 / 30) * 100 = 133%. As this is over 100%, the risk is always considered as 100%.

CASE 2: If the first order check rule fails, the formula will be:

(5 / 30) * 100 = 16.7%

CASE 3: If only the Unsafe country check rule fails, the formula will be:

(20 / 30) *100 = 66.7%

So, in the latter case, even if only one rule failed, the risk score is medium, as the rule had a high weight on the total calculation.

In the order, you will find also a summary of which rules are impacting the risk score of that order.

Since the Fraud Risk Level we set is between 25% and 75%, the order is considered to be medium risk.
