About this UK inflation calculator
This free inflation calculator UK adjusts pounds for inflation between any two years using the Consumer Price Index (CPI) or CPIH. It’s helpful for comparing salaries, prices, savings and budgets across time.
Our UK inflation calculator works by adjusting the value of money using the
Consumer Price Index (CPI) or CPIH. The calculator compares the ratio of CPI in two different years,
from 1950 up to 2025. For example, £1,000 in 1990 adjusted for inflation is worth more than £1,000
today because prices have risen over time. This method allows you to calculate inflation across salaries,
savings, or goods, helping you understand real value changes over decades.
The UK’s average inflation rate since 1950 has been around 5% annually, but this has varied
significantly. In the 1970s, inflation exceeded 20%, while in the 2010s it averaged under 3%. Our calculator uses
official CPI data to measure these changes, so you can check how inflation impacts your money. For example,
a salary of £20,000 in 2000 has the same buying power as over £34,000 today. By using our
inflation calculator UK, you can compare purchasing power over time.
Deflation is when prices fall instead of rising, meaning money gains value over time.
The UK rarely experiences prolonged deflation, but there have been short periods, such as in 2009.
Our UK inflation calculator takes this into account. If CPI in a target year is lower than in the original
year, your adjusted amount will decrease. This is useful for comparing wages, property prices, and savings in times of
economic slowdown.
This calculator uses official CPI data from the UK Office for National Statistics and applies a simple
but effective formula:
Adjusted Amount = Original Amount × (CPI in Target Year ÷ CPI in Original Year).
It covers 1950–2025 with annual CPI values, interpolated where necessary.
Unlike the Bank of England inflation calculator, this tool is built for fast, client-side use on the web and is
mobile-friendly. It is designed for quick results, accurate calculations, and simple integration with financial content.
All results are estimates based on the UK CPI series. While this UK inflation rate calculator provides
reliable guidance for salaries, savings, or prices, keep in mind that inflation is measured using a “basket of goods”.
Your personal experience may differ depending on what you spend money on (for example, rent, fuel, or groceries).
This calculator is not financial advice, but it gives a clear indication of how prices have changed across decades.
