Inflation Pay Rise — FAQ
Answers to common questions about salary adjustments and UK inflation.
What is an inflation pay rise?
An inflation pay rise (or cost-of-living adjustment) is an increase in salary intended to maintain your purchasing power as prices for goods and services rise.
Why should my pay rise match inflation?
If inflation is 5% and your salary stays the same, you are effectively taking a 5% pay cut in terms of what you can buy. A 'fair' pay rise at least matches the CPI (Consumer Price Index) rate.
What inflation rate is used?
We fetch the latest ONS CPI Annual Rate (D7G7/MM23) data directly from the ONS API, cached and refreshed weekly. The calculator always uses the most recent available month.
Is this calculation 100% accurate?
This calculator is for informational purposes. While it uses official tax and inflation data, individual circumstances (like student loans or specific pension rules) may vary.
For employers
Salary reviews are easier when payroll data is connected.
Run pay reviews, track salary changes, and model pay rises from payroll-ready data instead of rebuilding the numbers in spreadsheets.
