The expense breakdown gives you visibility into exactly where your credits are going — broken down by quest, item type, participant count, and source (web or mobile).
Viewing Expenses
Navigate to your organization’s Billing page to see:
- Current balance — your available credits in dollars

Per-Quest Billing
The per-quest breakdown shows:

This helps you understand which quests are consuming the most credits and where your budget is going.

Budget Planning
Use the interactive price calculator to estimate your total study cost. Enter your participant count, number of prompts, experiments, and data types, and the calculator will show a detailed cost breakdown.
Your organization starts with free starter credits. For a small pilot study (10-20 participants with a single experiment), the starter credits may be sufficient.
