Inflation Calculator

Calculate the impact of inflation on purchasing power

How to use: Inflation silently erodes your money's purchasing power over time. Enter any amount in pounds, the expected annual inflation rate and the number of years. The calculator shows the future value needed to maintain the same purchasing power, the inflation impact (money lost to inflation), purchasing power loss percentage, and today's equivalent value. For example, £100 today might need £134 in 10 years at 3% inflation. This is critical for retirement planning, salary negotiations, and long-term financial goals to ensure your money keeps pace with rising costs.
