Use this UK cost of living inflation calculator to adjust prices for inflation and compare spending power over time. The calculator accounts for the UK's Consumer Price Index (CPI) to show how much more expensive goods and services have become.
How to Use This Calculator
To calculate the adjusted cost of living in the UK:
- Enter the original price of the item or service in the "Original Price" field
- Select the year when the price was current from the "Original Year" dropdown
- Select the year you want to adjust the price to from the "Target Year" dropdown
- Click "Calculate" to see the adjusted price
The calculator will display the adjusted price and show how much the price has increased or decreased due to inflation.
Formula Used
The cost of living inflation calculator uses the following formula to adjust prices:
Where:
- Original Price - The price of the item or service in the original year
- CPI Original Year - Consumer Price Index for the original year
- CPI Target Year - Consumer Price Index for the target year
The calculator uses UK CPI data from the Office for National Statistics (ONS).
Worked Example
Let's say you bought a house in 2010 for £200,000. You want to know what that would be worth in 2023 accounting for inflation.
- Enter £200,000 as the original price
- Select 2010 as the original year
- Select 2023 as the target year
- Click "Calculate"
The calculator will show that the adjusted price is approximately £275,000, meaning the same house would cost 37.5% more in 2023 due to inflation.
Interpreting Results
The adjusted price shows how much more (or less) an item or service would cost in the target year compared to the original year, accounting for inflation.
If the adjusted price is higher than the original price, it means the item has become more expensive due to inflation. If it's lower, the item has become cheaper.
Use this information to:
