## How do I calculate GST from a total?

The formula for GST calculation:

- Add GST: GST Amount = (Original Cost x GST%)/100. Net Price = Original Cost + GST Amount.
- Remove GST: GST Amount = Original Cost – [Original Cost x {100/(100+GST%)}] Net Price = Original Cost – GST Amount.

## What is the formula to find GST?

Thus, a simple formula arises: GST Amount = (Original Cost*GST Rate Percentage) / 100. Net Price = Original Cost + GST Amount.

## What is GST inclusive?

## How do you add 15% to a price?

15% is 10% + 5% (or 0.15 = 0.1 + 0.05, dividing each percent by 100). Thinking about it this way is useful for two reasons. First, it’s easy to multiply any number by 0.1; just move the decimal point left one digit. For example, 75.00 x 0.1 = 7.50, or 346.43 x 0.1 = 34.64 (close enough).
