Use recorded changes in UK prices
The calculator compares the published UK price level for 1970 with today’s price level. It follows the recorded changes rather than assuming the same inflation rate every year.
This guide puts every amount into today’s money so examples from different years can be compared on the same basis. Very old estimates are less certain than recent official CPI figures.
- Treat the result as a broad guide to everyday prices
- Check the exact ONS series when a month or measure matters
- Use separate evidence for wages, homes, gold or a particular product
Place 1970 before the decade’s largest shocks
A 1970 amount predates the first oil shock and the highest UK inflation rates of the decade. Comparing 1970 with later checkpoints shows that the price path was uneven.
Check the ONS historical figures for the exact measure and year. A single headline about the 1970s should not be applied to every year in the decade.
Read prices and wages as different comparisons
CPI asks what broad basket of consumer goods a sum could buy. A wage comparison asks how earnings changed, while a house-price comparison asks about an asset market.
Use the CPI answer as a starting point, then check ONS earnings figures or the price history of the particular product if that is what the amount represents.
