Percentage Increase in Prices
A percentage increase is found with ((New − Old) ÷ Old) × 100. Expressing a price rise as a percentage — rather than just a money amount — shows whether the increase is small or significant relative to the original.

Think about this money choice
Bola's favourite bread cost 200 in local currency last month. This month it costs 240 in local currency.
How it works
A percentage increase tells you how much a price has gone up relative to the original. Formula: ((New price − Old price) ÷ Old price) × 100. This number matters because it tells you whether a price rise is small or significant — not just how much more it costs.
Try a real-life example
Real-life money moment: Bola's favourite bread cost 200 in local currency last month. This month it costs 240 in local currency. Increase: 40 in local currency. Percentage: (40 in local currency ÷ 200 in local currency) × 100 = 20%. The bread is 20% more expensive — a significant rise for a staple food.
