Frequently asked questions
What does AI agent usage metering cost include?
It includes ingesting and storing events (Segment, PostHog, Rudderstack, Kinesis, etc.), billing-subscription platform fees, payment processing, tax calculation, failed-payment recovery (dunning), revenue-recognition tooling, and the finance/ops labor to reconcile and audit the stack.
How does usage-based pricing change the estimate?
Usage-based products generate more events per dollar of revenue and usually more invoices/payment methods. The calculator scales event-ingestion cost by monthly events and transaction fees by the number of invoices, so a low APU (average revenue per user) product can have high billing overhead as a percent of revenue.
When is self-hosted metering cheaper?
Self-hosted Kafka/ClickHouse or Kinesis + Lambda typically has the lowest per-event cost at scale but adds fixed engineering time. The calculator shows cost per 1M events and operations labor, so you can compare managed vs self-hosted including maintenance.
What is revenue-at-risk from failed payments?
The dunning section estimates how much revenue fails each month and the cost to recover it. Providers like Churnkey charge a percentage of recovered revenue; Stripe Smart Retries is free but less aggressive.
Can I compare payment processors?
Yes. The payment comparison table recalculates transaction fees using your invoice count and average invoice value, then shows the cheapest option. Stripe, PayPal, Adyen, and Square rates are editable defaults.
Rates are approximate list prices and change frequently. Use this calculator for planning, not for financial or tax advice.
