Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £10.00 in 1930 would be equivalent to £10.75 in 1925, an absolute change of £0.75 and a cumulative change of 7.51%.

Compare these numbers to the US's overall absolute change of $0.48 and total percent change of 4.79%.

Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. Breaking down these categories helps explain the main drivers behind price changes.

This chart shows the average rate of inflation for select CPI categories between 1930 and 1925.

Compare these values to the overall average of -0.93% per year:

How to calculate inflation rate for $10, 1925 to 1930

Our calculations use the following inflation rate formula to calculate the change in value between 1925 and 1930:

Then plug in historical CPI values. The U.S. CPI was 16.7 in the year 1930 and 17.5 in 1925:

$10 in 1930 has the same "purchasing power" or "buying power" as $10.48 in 1925.
