Explanation: The formula calculates the difference between new and old values, divides by the original value to get a ratio, then converts to percentage by multiplying by 100.
Details: Understanding percentage increases helps UK consumers track inflation, employees evaluate salary raises, businesses analyze sales growth, and investors assess portfolio performance. It provides a standardized way to compare changes across different scales.
Tips: Enter the original value and new value in pounds sterling (£). Both values must be positive numbers. The calculator will show the percentage increase between them.
Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase shows the numerical difference (New - Old), while percentage increase shows this relative to the original value, making comparisons easier.
Q2: How do I interpret negative results?
A: A negative result indicates a percentage decrease rather than increase, showing the value has gone down.
Q3: Why use percentage instead of absolute numbers?
A: Percentages allow comparison across different scales - e.g., a £1,000 increase means different things if the original was £2,000 vs £200,000.
Q4: How is this used in UK salary negotiations?
A: Employees often request raises as percentage increases to maintain purchasing power against inflation and reflect their growing value to the company.
Q5: What are typical percentage increases for UK house prices?
A: Annual UK house price increases typically range 2-10%, varying by region and economic conditions.
