Giving the following information:

You deposit $1,900 in your savings account that pays an annual interest rate of 3.25%. The inflation rate is 1.09%.

In this example, we have two different and opposite effects. The interest rate increases your purchasing power. If the inflation rate is 0, the purchasing power will increase (in one year) 3.25%.
