FAQ

Nigeria's VAT rate is 7.5% since 2020 (raised from 5%). To calculate VAT on a price: VAT amount = Price × 0.075. To get the VAT-inclusive price: Price × 1.075. To extract VAT from a VAT-inclusive price: Price ÷ 1.075 × 0.075. Use the "X% of Y" tab with 7.5 as X and your price as Y.

Use the "% Change" tab. Enter your old salary as "From" and your new salary as "To". The calculator shows the exact percentage increase. For example, going from ₦300,000 to ₦360,000 is a 20% increase. Note that a 20% nominal raise may be less than inflation (15%+), meaning your real purchasing power increase is only about 5%.

These are different! If an interest rate rises from 10% to 15%, it increased by 5 percentage points, but by 50% (a 50% relative increase). Percentage points measure absolute differences between percentages. Percent (%) measures relative change. Nigerian journalists and financial reports sometimes confuse these — always clarify which is meant when discussing rate changes.
