# Configure the management fee calculation settings
The management fee can be calculated as one of the following:
* The annual percentage of the subscribed investment account’s balance or equity at the moment of fee payment, which is paid periodically (daily, weekly, or monthly):
`Management fee = Fee%/100 * Number of active days/Year * Account balance (or equity)`
* The percentage of the subscribed investment account’s balance or equity at the moment of fee payment, which is calculated for a selected period (daily, monthly, or weekly):
`Management fee = Fee%/100 * Number of active days/Period * Account balance (or equity)`
In the settings described below, you can select if you want to use balance or equity for the calculations.
In the formulas:
* **Fee%** is the management fee percentage specified in a fee plan.
* **Number of active days** is the number of days an investor has been subscribed to a master account or the number of days passed since the last payment.
* **Year** is always considered to be 365 days for calculation purposes.
* **Period** is the payment period specified in the fee plan. Possible values:
* **Daily** – the fee is charged every day. The period duration is 1 day.
* **Weekly** – the fee is charged every Monday. The period duration is 7 days.
* **Monthly** – the fee is charged on the first day of each month. For calculation purposes, the period duration is always considered to be 30 days.
* **Account balance (or equity)** is the subscribed investment account’s balance or equity at the moment of fee payment.

### **Example 1**
Suppose that the management fee is configured to be calculated as the annual percentage, based on the subscribed investment accounts’ balances:
`Management fee = Fee%/100 * Number of active days/Year * Account balance`
In the fee plan for a master account, the management fee is set to 15 percent annually, which must be paid daily. An investor subscribed to the master account on April, 15. The next daily management fee is charged on\
April, 16.
Suppose that the investment account’s balance is 3000 USD at the moment of fee payment on April, 16. In this case, the management fee amount is calculated as follows:
`Fee% = 0.15`\
`Number of active days = 1 day`\
`Year = 365 days`\
`Account balance = 3000 USD`\
\
`0.15 * 1/365 * 3000 = 1.23 USD`
### **Example 2**
Suppose that the management fee is configured to be calculated as the percentage for a selected period, based on the subscribed investment accounts’ balances:
`Management fee = Fee%/100 * Number of active days/Period * Account balance`
In the fee plan for a master account, the management fee is set to 2% monthly. An investor subscribed to the master account on April, 15. The next monthly management fee is charged on May, 1.
Suppose that the investment account’s balance is 3000 USD at the moment of fee payment on May, 1. In this case, the management fee amount is calculated as follows:
`Fee% = 0.02`\
`Number of active days = 30 - 15 = 15 days`\
`Period = 30 days`\
`Account balance = 3000 USD`\
\
`0.02 * 15/30 * 3000 = 30 USD`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.b2copy.b2broker.com/admin-guide/configure-b2copy/configure-the-management-fee-calculation-settings.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
