# 多幣別與匯率

多幣別可以用於帳單、帳戶、預算、投資和統計。帳戶和帳單會一直保留原幣別，匯率用於跨幣別彙總和顯示。

## 管理幣別和匯率

開啟 **貨幣與匯率**，查看或編輯不同幣別之間的匯率。

{% hint style="info" %}
帳戶和帳單會一直保留原幣別；修改匯率只會影響跨幣別換算和彙總顯示，不會改寫原始金額。
{% endhint %}

## 顯示規則

| 位置    | 顯示方式         |
| ----- | ------------ |
| 帳戶資料列 | 顯示帳戶自己的幣別和餘額 |
| 資產頂部  | 換算為目前統計幣別後彙總 |
| 父子帳戶  | 子帳戶先換算為主帳戶幣別 |
| 統計與預算 | 依頁面選擇的幣別顯示   |
| 換匯帳單  | 分別保留轉出和轉入金額  |

## 記錄換匯

1. 新增帳單時選擇 **換匯**。
2. 選擇轉出帳戶和轉入帳戶。
3. 填寫兩側金額或本次匯率。
4. 儲存後，兩個帳戶餘額會同時更新。

## 淨資產換算

資產頁面會依目前篩選範圍計算資產、負債和淨資產。帳戶資料列、頂部彙總和目前淨資產都只計算截至目前時間已經發生的帳單；未來帳單會在到達帳單時間後影響餘額。淨資產走勢會依帳單日期回放帳戶餘額，並套用帳本篩選、帳戶統計設定和對應日期的匯率。

{% hint style="warning" %}
帳戶資料列與頁面彙總不同時，請先檢查統計幣別、帳本篩選、父子帳戶、匯率，以及帳戶是否被排除於統計之外。
{% endhint %}

## 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://help.daak2.com/zh-tw/ji-zhang/currency.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.
