Based on UK CPI (Consumer Prices Index) data from the Office for National Statistics. Data covers 1988 to 2024.
The Consumer Prices Index (CPI) measures the average change in prices of a 'basket' of goods and services over time. It is the UK's primary measure of inflation and is produced monthly by the Office for National Statistics (ONS).
The Retail Prices Index (RPI) is an older measure that includes housing costs such as mortgage interest payments, which CPI excludes. RPI tends to run slightly higher than CPI. Student loan interest (Plan 1) and some rail fare increases are linked to RPI.
The Bank of England has a mandate to keep CPI inflation at 2% per year. When inflation is above target, the Bank typically raises interest rates to cool spending. When below target, it may cut rates to stimulate the economy.
If your savings account pays less interest than the current inflation rate, your money is losing purchasing power in real terms even if the nominal balance grows. A 5% savings rate during 10% inflation means you are getting poorer in real terms.
Real wage growth occurs only when pay rises faster than inflation. Between 2010 and 2023, UK real wages were largely stagnant because pay increases often failed to keep pace with CPI. This is a key driver of reduced living standards.
See what an amount of money from any year since 1988 is worth in today's terms, adjusted for UK inflation using official CPI data.
£100 in 2000
Approximately £210 in 2024 (110% increase)
£1,000 in 1990
Approximately £3,170 in 2024 (217% increase)
£500 in 2019
Approximately £666 in 2024 (33% increase)
The Bank of England inflation calculator goes back to 1209 — over 800 years of price data. A basket of goods costing £1 in 1750 would cost roughly £200 today.
Begin with the decision or task you want this page to support. Find out what any amount of money is worth in today's terms using official UK CPI data back to 1988. Write down the expected kind of answer before entering values, so you can notice if a default, unit, or mode does not fit your situation. If more than one input could change the result, hold the others steady while you test one value at a time. This makes it easier to understand what the tool is responding to instead of treating the first number on screen as a complete recommendation.
Follow the page instructions in order and check the labels as you go. The first step is: Enter an amount of money.. Next, select the original year (the year the money was worth that amount). Use consistent units and a consistent time period, and avoid replacing an unknown value with zero unless the tool explicitly treats zero as a valid input.
The page's worked example is a reference point, not a forecast for every situation. It shows how the inputs lead to an output: Approximately £210 in 2024 (110% increase) Compare the assumptions in that example with your own values, then check the units, rounding, and any optional settings before comparing results. If your scenario differs, describe that difference explicitly rather than expecting the example's answer to transfer unchanged.
Use the result as one part of a decision rather than a substitute for the context around it. If you are comparing alternatives, run each one with the same definitions and change only the factor you want to compare. For repeated tasks, save a short note of the inputs and date; this makes later results easier to reproduce and helps distinguish a real change from a difference in how the values were entered.
A useful final check is to compare the answer with a second route: a hand calculation, a known example, an official reference, or the instructions for the service that will receive the result. One point worth checking on this page is “What data does this inflation calculator use?” A close match on a simple case can confirm the basic method; it does not prove that every complex case is covered.
This tool provides an estimate for general information and planning. It is not financial, tax, investment, or lending advice. Check current rules, rates, fees, and provider terms before making an important decision. Keep the estimate separate from a final decision or filing, and confirm current requirements with the appropriate authority or qualified professional.
The calculator uses UK Consumer Prices Index (CPI) data published by the Office for National Statistics (ONS). CPI measures the average change in prices of a representative basket of goods and services bought by households, including food, clothing, energy, housing costs, and transport. The data covers annual averages from 1988 to 2024.
The modern UK CPI series starts in the late 1980s. Earlier UK inflation data exists but uses different methodologies (primarily RPI). Starting from 1988 ensures consistent, comparable data across the full date range. If you need data going back further, the Bank of England's own inflation calculator covers prices from 1209 using a composite index.
CPI (Consumer Prices Index) is the UK's main inflation measure and excludes housing costs such as mortgage interest and council tax. RPI (Retail Prices Index) is an older measure that includes these housing costs and therefore tends to run higher than CPI. Student loan interest on Plan 1 and some rail fares are linked to RPI rather than CPI.
The formula is: Adjusted value = Original amount × (Target year CPI ÷ Original year CPI). For example, £100 in 2000 (CPI: 49.7) adjusted to 2024 (CPI: 104.5) equals £100 × (104.5 ÷ 49.7) = approximately £210. This tells you that £100 in 2000 has the same purchasing power as £210 today.
Yes. If your savings account pays less interest than the current inflation rate, your money loses purchasing power in real terms even though the nominal balance grows. For example, 3% savings interest during 7% inflation means your real return is approximately −4%. This is why investing in assets that historically outpace inflation (like equities) is recommended for long-term goals.
