The most important point to remember regarding inflation and interest rates is:
Inflation reduces the value of money. The interest rate of the savings account should be subtracted from the inflation rate to understand its effect on the value of the balance.
This statement highlights the relationship between inflation and interest rates, emphasizing that the nominal interest rate on a savings account may not fully compensate for the loss of purchasing power due to inflation. If the inflation rate is higher than the interest rate earned, the real value of savings declines.
