This post serves as a detailed explanation of our pricing plans and is intended for reference purposes. To get started with the basics and explore our interactive price calculator, please head to the [pricing page](https://logto.io/pricing). ## Logto pricing strategy: Pay-as-you-go and usage-based pricing As a foundational premise, Logto offers four plans: Free, Hobby, Pro, and Enterprise. The Free plan and the Enterprise plan operate differently with their own distinct approach while Hobby and Pro follow monthly usage-based pricing and are influenced by the number of Monthly Active Users (MAU). The MAU is the primary variable that determines the monthly cost for Hobby and Pro plan subscribers. ## MAU statistical caliber Logto offers a transparent measurement of Monthly Active Users (MAU): An MAU refers to a user who has engaged in at least one [token exchange](https://openid.net/specs/openid-connect-core-1_0.html#TokenRequest) with any Logto Cloud server within a billing cycle (30 days by default). ## The formula For most products in the market, the total monthly invoice is calculated as follows: Total monthly invoice = Base Price + MAU Unit Price × (MAU - Included MAU) In the case of Logto, we introduce a tiered pricing model that allows for better segmentation of your Monthly Active Users (MAU) based on their levels of activity and engagement. In the Logto environment, the formula for calculating the tiered MAU is as follows: Total monthly invoice = Base price +
  Tier 1 MAU × Tier 1 Unit Price +
  Tier 2 MAU × Tier 2 Unit Price +
  Tier 3 MAU × Tier 3 Unit Price To gain a better understanding of how the formula functions, it's important to be familiar with the definitions of the variables involved. - **Total Monthly Invoice**: The total amount of money customers are charged for Logto services within a 30-day billing cycle. - **Base Price**: A fixed charge specific to each plan at the beginning of a billing cycle. - **Tiered MAU**: The count of monthly active users who log in to the app within a specific range of days during a billing cycle. - **Tiered Unit Price**: The price charged for each tiered MAU Here's a table for reference: Logto pricing model table

**Tiered MAU** and **tiered unit prices** are key aspects of our pricing model. Let's delve into the specifics to better understand them. ## Tiered MAU A crucial question is how users are categorized into different tiers or segments based on their active login days in an app. - **Tier 1 MAU (Occasional MAU)**: If users engage in your app within **3 days** during a month, they will be classified as Tier 1 MAU. - **Tier 2 MAU (Frequent MAU)**: If users engage in your app **between 4 - 6 days** during a month, they will be classified as Tier 2 MAU. - **Tier 3 MAU (Almost daily MAU):** If users engage in your app **beyond 7 days** during a month, they will be classified as Tier 3 MAU. ## Tiered unit prices Naturally, the unit price is charged for each tiered MAU. In the case of Hobby and Pro plans, the following unit prices apply. - For **Tier 1 MAU (Occasional MAU),** the Unit Prices are **$0.008** for the Hobby plan and **$0.024** for the Pro plan. - For **Tier 2 MAU (Frequent MAU)**: the Unit Prices are **$0.012** for the Hobby plan and **$0.032** for the Pro plan. - For **Tier 3 MAU (Almost daily MAU)**: the Unit Prices are **$0.016** for the Hobby plan and **$0.048** for the Pro plan. ## Examples ### I. The most simple example Consider an app with 10,000 Monthly Active Users (MAU). If all MAU are categorized under the Tier 1 pricing: Min: 16 + 10,000 × $0.008/MAU = $96 If all MAU are categorized under the Tier 3 pricing: Max: 16 + 10,000 × $0.016/MAU = $176 As a customer, you are allocated a monthly budget ranging between $96 and $176 in total. ### II. A little bit complex example Imagine an app with **10,000** Monthly Active Users (MAU) and an average of **6** sign-in days. In this scenario, the app experiences an average of **2000** Daily Active Users (DAU). Let's consider the scenario where the app runs an ad campaign to acquire new users and experiences a spike in Daily Active Users (DAU) to **40,000** on the last day of the billing cycle. As a result of the campaign, approximately **38,000** new users join the app. The total Monthly Active Users (MAU) for this month would then increase to **38,000** (new users) + **10,000** (existing users) = **48,000**. Considering the Monthly Active Users (MAU) count of **48,000**, the price would be calculated like this if we follow the industry standard pricing model: 16 + 48,000 × $0.016/MAU = $784 However, this doesn’t make sense. Our customers would feel wronged. 😢 Ironically, this scenario is extremely common for early-stage startups with unstable user volumes. Therefore, in this case, Monthly Active Users (MAU) is not an accurate representation of the actual usage. As previously mentioned, the usual Monthly Active Users (MAU) for the app is **10,000** with an average of **6** sign-in days. This segment of users falls into the Tier 2 category. The remaining **38,000** users, who joined during the spike, would most likely be classified as Tier 1 MAU since this increase represents an unusual event. | Tier 1 ($0.008/MAU) | Tier 2 ($0.012/MAU) | Tier 3 ($0.016/MAU) | | ------------------- | ------------------- | ------------------- | | 38,000 | 10,000 | 0 | As a result, the total monthly cost for the unusual spike in MAU can be calculated like this: 16 + 38,000 × $0.008/MAU + 10,000 × 0.012 = $440 ## Closing We hope this article has provided you with a thorough understanding of Logto's pricing model.
