# How percentage is calculated

The **Change value** is the **difference between the latest price on the symbol and the previous period's closing price**.

**Percent Change**, meanwhile, is calculated by **dividing the Change value by the previous period's close and multiplying the result by 100**.

```
Percent Change Calculation:

Daily Chg = (Price - Prev Day's Close) / Prev Day's Close * 100
Weekly Chg = (Price - Prev Week's Close) / Prev Week's Close * 100
Monthly Chg = (Price - Prev Month's Close) / Prev Month's Close * 100
```

Keep in mind that other websites could use a different calculation, so our percent change value might not match those sources. We recommend checking with the sources you use to learn what calculation they use for percent change.
