 **B. Usage-Based Costs**

**1. Storage Pricing**

* Based on MongoDB clusters with sharding and backup included.
* For storage requirements exceeding 1000 GB, custom pricing can be offered.
* Calculated daily based on the peak storage used each day
* Aggregated monthly for billing purposes

| **Storage Tier** | **Storage Credits(/GBday)** |
| ---------------- | --------------------------- |
| 0-500 GB         | 116666.6667                 |
| 501-1000 GB      | 83333.33333                 |

**2. Instance Pricing**

* Instance calls are charged based on the number of invocations and the execution time taken for the instance

Pricing Formula:

* **Invocations Credits** = 9.46 \* (# of Invocations)
* **Execution Credits** = 0.143 \* (# of Invocations) \* Avg Execution Runtime (ms)

**Total Instance Credits = Invocation Credits + Execution Credits**

3. **API Calls Pricing**

* Charged based on the number of requests and execution time.

Pricing Formula:

* **Invocations Credits** = 21.85 \* (# of API Calls)
* **Execution Credits** = 0.2 \* (# of API Calls) \* Avg Execution Runtime (ms)

**Total API Credits = Invocation Credits + Execution Credits**

Estimated Price: $14 per 100K Calls (may vary slightly based on plan)

Assuming Avg Execution Runtime to be 600 ms and the user is on a Scale Plan.
