Monthly Active Users (MAU)
Azure Active Directory B2C is priced on a Monthly Active User (MAU) basis, helping customers to reduce costs and plan ahead with confidence. A MAU is counted when a unique user authenticates within a given calendar month.
Azure AD B2C is billed at the following standard tier rates.* Enterprise Agreement customers will be billed at a low, flat rate.
|Monthly Active Users/Month||General Availability Price||Enterprise Agreement Price|
|First 50,000||Free||Enterprise Agreement customers are eligible to switch to MAU-based billing which includes the Free tier of 50,000 MAUs. Subsequent Azure AD B2C usage will be billed at a low, flat rate per MAU. For more information, please contact your partner or Microsoft representative.|
|Greater than 10,000,000||$0.0025|
|MFA and SMS/Phone Events||$0.03 per SMS/Phone event|
We listened carefully to customers about their needs regarding predictable, intuitive, and cost-efficient billing for customer identity solutions. With MAU-based billing, customers benefit from:
- Expanded Free tier: The new Free tier stretches further by granting customers 50,000 MAUs per month—enabling more authentications per unique user than under the previous free allotment of 50,000 authentications. Most customers—with 50,000 or fewer MAUs per month—will be able to use Azure AD B2C for free.
- Predictable forecasting: Estimating monthly billing on a per MAU basis is simpler and more predictable than trying to forecast the number of monthly authentications.
Usage-based billing: Pay only for your MAUs. Customers are not charged for a MAU’s subsequent authentications or for storing inactive users within that calendar month.
For example, if you have 100,000 monthly active users (MAUs) using standard features, your monthly bill would be $275 regardless of how many times each MAU authenticates:
(50,000 MAUs x $0 (Free tier)) + (50,000 MAUs x $0.0055) = $275
A worldwide flat fee of $0.03 is billed for each MFA attempt or SMS/Phone event.

We worked closely with our customers to understand their needs regarding predictable, intuitive, and cost-efficient billing for customer identity.
With the Free tier of 50,000 MAUs per month, the vast majority of customers will realize immediate cost savings and be able to use Azure AD B2C for free. All customers benefit from more accurate forecasting, with predictable month-to-month charges.
Enterprise Agreement customers are eligible to switch to MAU-based billing. If you exceed the Free tier of 50,000 MAU, subsequent Azure AD B2C usage will be billed at a low, flat rate per MAU. For more information, please contact your partner or Microsoft representative.
We consider new customers to be any customer who links an Azure AD B2C tenant to a subscription as of November 1, 2019. New customers will be billed monthly on a per MAU basis.
You may be a new customer if you:
- Created a new tenant on November 1, 2019 or later and linked the tenant to an Azure subscription, creating a new Azure AD B2C Resource
- Previously created a tenant which did not have an Azure subscription as of November 1, 2019
A monthly active user (MAU) is a unique user that performs an authentication within a given month. For example, a user that authenticates multiple times within a given month is counted as one MAU. Customers are not charged for a MAU’s subsequent authentications during the month, nor for inactive users.
Authentications may include:
- Active, interactive login by the user
- Passive, non-interactive login (such as single sign-on, sign-up, sign-in, token refresh, and password change)
Additional operations that are counted as an authentication include: login to a portal; redeeming an invitation; authenticating to perform an admin action; and when an application exchanges a refresh token for a new identity token or access token for that user.
If you choose to provide higher levels of assurance using Multi-Factor Authentication (MFA) for Voice and SMS, you will continue to be charged a worldwide flat fee of $0.03 for each MFA attempt that month, whether successful or unsuccessful. The worldwide flat rate provides greater predictability, by removing the price variations for SMS messages that are dependent on the telecom carrier or destination phone number.
For example, if you have 100,000 monthly active users (MAUs) who each make two MFA attempts that month, you would be billed $6000, in addition to your usage:100,000 MAUs x 2 MFA attempts/each = 200,000 MFA attempts
200,000 MFA attempts x $0.03/attempt = $6000
Your total bill for B2C and MFA usage that month would be:$275 (MAU-based usage) + $6000 (MFA protection) = $6275
