Sometimes, we want to calculate x% of a number with JavaScript.

In this article, we’ll look at how to calculate x% of a number with JavaScript.

### Calculate x% of a Number with JavaScript

To calculate x% of a number with JavaScript, we can divide `x`

by 100 then multiply by the number we want to compute the percentage for.

For instance, we can write:

```
const x = 35.8
const result = (x / 100) * 10000;
console.log(result)
```

We assign the percentage number to `x`

.

Then we divide that by 100 to get a decimal number with the fraction that we want to multiply the number with.

We multiply that by 10000 to get 35.8% of 10000 and assign that to `result`

.

Therefore, `result`

is 3580.

### Conclusion

To calculate x% of a number with JavaScript, we can divide `x`

by 100 then multiply by the number we want to compute the percentage for.
