# Usage and credits

> How online session-days, regional rates, volume brackets, and overages consume credits.

Number usage is based on **online session-days**, not a per-message charge. A
connected number is charged once for each UTC day it is online. A disconnected
number does not consume session-day credits for that day.

## Calculate session-day usage

Use:

```text theme={null}
connected numbers × connected days × tier rate × country multiplier
```

For a Basic team, two Standard numbers connected for 30 days use:

```text theme={null}
2 × 30 × 25 = 1,500 credits
```

That is $15 USD or R$75 BRL at the current credit purchase rate.

For `+55` numbers, apply the 70% country multiplier:

```text theme={null}
1,500 × 0.70 = 1,050 credits
```

## Volume brackets

Premium and Enterprise teams use the connected-number bracket for each online
session-day. Basic uses the first bracket regardless of number count.

| Connected numbers |       Standard |            Pro |
| ----------------: | -------------: | -------------: |
|              1–10 | 25 credits/day | 36 credits/day |
|             11–40 | 23 credits/day | 33 credits/day |
|            41–200 | 22 credits/day | 32 credits/day |
|           201–250 | 17 credits/day | 24 credits/day |
|              251+ | 10 credits/day | 14 credits/day |

The bracket is based on connected-number count. The `+55` multiplier is
applied after the bracket rate.

## Overages

Number tiers include data, outbound-call, and serverless-call allowances. Usage
above an allowance is charged as follows:

| Usage            |         Credit rate |
| ---------------- | ------------------: |
| Data             |       10 credits/GB |
| Outbound calls   |     20 credits/call |
| Serverless calls | 100 credits/million |

Free testing numbers use 0 session-day credits. Scale rates and limits are set
by contract.

## Monitor your balance

The Billing screen shows the organization's current credit balance and lets an
authorized member set a low-balance reminder threshold. Available payment
methods, currencies, and final amounts are shown in checkout.
