About Inflation Impact On Savings Calculator

When the interest rate is below inflation the balance rises while its purchasing power falls. The real rate makes that visible: a 4% deposit against 6% inflation loses nearly 2% of value every year.

Formula

Real value of savings

Real = amount × (1+r)^t / (1+inflation)^t; real rate = (1+r)/(1+i) - 1

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Figures are estimates for planning only. Prices, returns, inflation and personal circumstances all change. This is not financial or tax advice — speak to a qualified adviser before making decisions.
