Interactive Calculator Shows Inflation’s Impact on Savings, Highlights Real-Term Losses

A new inflation calculator reveals how rising Consumer Prices Index (CPI) levels erode the real value of savings, helping consumers assess returns against current inflation rates. Users input their savings amount and interest rate to see projected annual returns versus inflation, based on the latest CPI data from the Office for National Statistics. Assuming steady inflation and no changes in interest rates, the tool calculates real-term losses over five years. For example, £20,000 in an account earning 2.45% yields £490 interest but results in a £183.75 real-term loss after inflation. Switching to a top-paying easy-access account at 5%, such as Cahoot’s, would increase real value by £348.84 annually. The tool underscores the importance of seeking higher-yielding savings accounts or cash ISAs to preserve purchasing power, especially during periods of high inflation. It allows side-by-side comparisons of different interest rates, showing how small increases can significantly reduce inflation-related losses over time.
