Inflation reduces the purchasing power of your savings. Real return = nominal interest - inflation rate (2-3%). If your savings account pays 4% and inflation is 3%, your real return is just 1%. Use our calculator to see both nominal and inflation-adjusted growth.

💰 How Savings Grow

Savings growth combines compound interest and regular contributions:

Regular Contributions: Consistent saving builds wealth
Formula: Future Value = P(1+r)^n + PMT[((1+r)^n-1)/r]

With £100/month: £21,911 + £28,533 = £50,444
