1. What is Wage Percentage Increase?

The wage percentage increase calculation shows how much a salary has changed between two points in time, expressed as a percentage of the original salary. This is particularly important for UK tax planning and understanding pay rises.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Wage — Current or proposed salary amount in GBP
• Old Wage — Previous salary amount in GBP

Explanation: The formula calculates the difference between the two wages, divides by the original wage to get a decimal, then converts to percentage by multiplying by 100.

3. Importance for UK Tax Purposes

Details: Understanding wage increases helps with tax planning in the UK, as significant pay rises may move you into a higher tax bracket or affect benefits. It's also useful for negotiating salaries and comparing job offers.

4. Using the Calculator

Tips: Enter both wage amounts in GBP (before tax). The calculator works with both annual and monthly figures, but be consistent (don't mix annual with monthly).
