Frequently Asked Questions
How do I calculate what percentage a number is of another?
Divide the part (X) by the total (Y) and multiply the result by 100. Formula:
(X ÷ Y) × 100. For example, if you scored 450 marks out of 600, your percentage is (450 ÷ 600) × 100 = 75%.
How do I calculate a percentage increase or decrease?
Subtract the original number from the new number, divide that difference by the original number, and multiply by 100. Formula:
((New - Old) ÷ Old) × 100. A positive result indicates percentage growth, while a negative number denotes a drop.
How do I calculate GST or sales tax using percentages?
To add GST (e.g. 18%), multiply the base price by 0.18 to find the tax amount, then add it to the base. Or directly multiply base price by 1.18 for the gross total.
