## Understanding Workflow Costs

Each workflow is made up of different steps that use credits as they run. The cost is calculated based on two main factors:

1. How many steps are in your workflow
2. How long each step takes to run

Think of credits like time units - the longer a step runs, the more credits it uses.

Here's a breakdown of costs for each type of step:

| Step Type    | Credits Used (per 0.1 sec) | Cost for Running 1,000 Times | Example Action                                                         |
