Inflation Calculator
See what any amount of money is worth after inflation — in the future, or what something cost in today's money. Essential for understanding real investment returns and long-term planning.
The Impact of Inflation
The Compounding Effect
At 3% annual inflation, prices double roughly every 24 years (Rule of 72: 72 ÷ 3 = 24). The UK inflation rate over the last century has averaged ~3.5%. Over 30 years at 3.5%, £10,000 in today's money would need to become £28,000 just to have the same purchasing power.
Real vs Nominal Returns
A 7% investment return with 3% inflation has a real return of approximately 4% (nominal − inflation). Always evaluate investment returns in real terms — nominal returns can look impressive while hiding real value destruction.
What This Means for Savings
Cash in a bank account earning less than the inflation rate is losing real value every year. This is why long-term savings need growth-oriented investments, not just savings accounts — especially for goals 10+ years away.
