# Committed + overage pricing

A common pricing model is where you get a number of units included in the monthly fee and extra units are billed per unit in arrears. Consider the website pricing  below.

| Small                      | Medium                     | Large                      |
| -------------------------- | -------------------------- | -------------------------- |
| $20/month                  | $40/month                  | $80/month                  |
| 100 requests included      | 250 requests included      | 500 requests included      |
| Additional requests: $0.25 | Additional requests: $0.22 | Additional requests: $0.20 |

The monthly fee is billed in advance every billing period and at the end of the period, any additional requests are billed in arrears. The way to configure this setup in Bunny is using a combination of recurring and usage-based charges as shown below.

To get the usage-based calculation working, simply send usage-based records (per request, daily, weekly or monthly) for each customer to [Bunny's API](https://docs.bunny.com/developer/integrate/track-usage-for-billing). Quantities of 250 and below will fall into the free tier and anything over will get billed at $0.22 per request.
