Inflation is the invisible tax on your savings. With UK CPI at 2.8% in 2026, this is more important than ever to understand.
The Real Cost of Inflation on £10,000
Suppose you have £10,000 earning 1.5% interest. After a year you have £10,150. But if inflation is 2.8%, those items cost £10,280. You've lost £130 in real purchasing power despite having more money in your account. Over 10 years at these rates, your £10,000 falls to the buying power of just £8,760.
