# Revising estimate calculation logic

## Context

An estimate can be revised due to following reasons.

1. Due to revision in rates.
2. Due to deviations (less/excess) in SOR/ Non-SOR quantities.

And for both the revision, logic to calculate estimated to be implemented as given below.

## Details <a href="#details" id="details"></a>

1. For an estimate system should know the used and unused quantities of all the SORs/Non-SORs.
2. Used quantity to be fetched from approved MBs. In workflow MBs will not be considered to determine the used quantity.
3. Current effective rates to be applied to calculate the revised estimate amount and it will be calculated SOR/ Non-SOR wise as given below.
4. Amount = (Unused Quantity + Additional Quantity (if added any))\* current effective rate.
5. For newly added SOR/ Non-SOR, current effective rates are applied.

## Acceptance Criteria <a href="#acceptancecriteria" id="acceptancecriteria"></a>

The revised estimate amount is calculated using current effective rates on unused quantities of SORs.

## 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.digit.org/works/reference-implementations/muktasoft-v2.2/specifications/functional-requirements/user-stories/improvements/revising-estimate-calculation-logic.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.
