Every rate comes from [Pricing](https://docs.bithuman.ai/pricing).

## Estimate a month

Choose where the avatar renders, then how long sessions run. The estimate counts session minutes at the [rates](https://docs.bithuman.ai/pricing#serving--credits-per-live-minute). Billing: [How billing works](https://docs.bithuman.ai/pricing#how-billing-works).

One avatar session running 60 minutes a day for 30 days:

| Mode | Rate | Credits a month | At the top-up rate | Smallest plan that covers it |
|---|---|---|---|---|
| On the device or your servers | 2 credits per minute | 3,600 | $36.00 | Pro |
| bitHuman cloud avatar | 4 credits per minute | 7,200 | $72.00 | Pro |
| Managed voice chat, all-inclusive | 10 credits per minute | 18,000 | $180.00 | Business |
