Inflation Calculator — UK & International (2000–2025)
Inflation quietly erodes the purchasing power of money over time. £1,000 in 2010 buys significantly less today than it did then — and the same is true across every major economy. This free multi-country inflation calculator lets you see exactly how much a given amount in one year is worth in another, using official CPI (Consumer Price Index) data for eight countries including the UK, US, Eurozone, Canada, and Australia. It covers the period from 2000 to 2025, including the significant inflation spikes of 2022–2023 driven by post-pandemic supply chain disruption and energy price shocks. Use it to adjust historical salaries, contract values, financial settlements, or any other monetary figure for inflation.

Frequently Asked Questions
What is CPI and how is it used to calculate inflation?
CPI (Consumer Price Index) measures the average change in prices paid by consumers for a basket of goods and services over time. To calculate how much a sum in one year is worth in another, you divide the CPI of the target year by the CPI of the base year and multiply by the original amount. This gives you the "real" equivalent value adjusted for inflation.
Why does this calculator only go back to 2000?
CPI methodology and basket composition changed significantly before 2000 in many countries, making cross-era comparisons less reliable. For most practical purposes — salary comparisons, contract values, settlement amounts — the 2000–2025 range covers the relevant period. For older comparisons, the Bank of England's inflation calculator covers UK data back to 1209.
Why did inflation spike so sharply in 2022–2023?
The 2022–2023 inflation surge across most developed economies was driven by a combination of factors: supply chain disruptions from the COVID-19 pandemic, a surge in consumer demand as economies reopened, the Russian invasion of Ukraine causing energy and food price shocks, and fiscal stimulus measures that increased money supply. UK CPI peaked at 11.1% in October 2022 — the highest in 41 years.
How does UK inflation compare to the US and EU?
UK inflation in 2022–2023 was among the highest in the G7, partly due to its energy import exposure and labour market tightness. US CPI peaked at around 9.1% in June 2022 before falling faster than the UK. Eurozone HICP peaked at 10.6% in October 2022. The Bank of England's 2% inflation target is shared by the ECB and Fed.
Can I use this for salary negotiation?
Yes. If you want to argue that your salary has not kept pace with inflation, enter your salary from a previous year as the amount, select that year as the start year, and the current year as the end year. The result shows what your salary should be in real terms — i.e. what you would need to be earning today to have the same purchasing power.
