Frequently Asked Questions
How do I calculate a percentage of a number?
To find X% of Y: multiply Y by X, then divide by 100. Example: 7.5% of ₦50,000 = 50,000 × 7.5 / 100 = ₦3,750. This is the formula used for VAT, discounts, commissions and interest calculations.
How do I express one number as a percentage of another?
To find what percentage X is of Y: divide X by Y, then multiply by 100. Example: ₦15,000 out of ₦200,000 salary = 15,000 / 200,000 × 100 = 7.5%. This is useful for calculating savings rates, expense ratios, and budget allocations.
How do I calculate percentage increase or decrease?
Percentage change = (New Value − Old Value) / Old Value × 100. A positive result is an increase; negative is a decrease. Example: Salary raised from ₦250,000 to ₦300,000 = (300,000 − 250,000) / 250,000 × 100 = 20% increase.
How is percentage used in Nigerian tax calculations?
Percentages are central to Nigerian tax: PAYE uses progressive percentage bands (15%, 18%, 21%, 23%, 25%), pension is 8% of pensionable salary, NHF is 2.5% of basic salary, NHIS is 5%, and VAT is 7.5% of the transaction value. Understanding percentage calculations helps you verify your payslip.
What is the difference between percentage point and percent?
A percentage point is an absolute difference between two percentages. If inflation rises from 20% to 25%, it rises by 5 percentage points but by 25% as a percentage change. This distinction matters: a wage increase from 10% to 15% is a 5 percentage point increase, but a 50% increase in the wage growth rate.
