# Why Are Allowances for Certain Types Lower?

Archera's Guaranteed Commitment allowances & premiums are set primarily based on risk as assessed by Archera's underwriting algorithm. This means for certain instance types, services, and regions the number of Guaranteed Commitments available to purchase from Archera can be much lower than for others. This is based dynamically on the amount of demand for the commitments in the marketplaces Archera has access to.

For example, Archera tends to offer the highest Guaranteed Commitment allowances for common EC2 instance types in the most popular regions, given these are the most popular and in-demand commitment types. However, for less popular RDS instance types — which are not as in-demand as EC2 instances — the allowance can be much lower and average premiums higher.

There are also specific ways individual customers can increase their overall allowances as outlined in [How can I raise my Guaranteed Commitment Allowances?](/help-center/guaranteed-commitments/raise-allowances.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.archera.ai/help-center/guaranteed-commitments/allowances-lower-types.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
