You have been given a raise. However, inflation is rising as well.
2019: $70 wage per day CPI = 100
2020: $77 wage per day CPI = 116
% increase in your nominal wages =
Increase in CPI =
When were you better off?
Why?
Percentage increase in nominal wage is simply the percentage increase in money wage of the person.
Using the above information,
So, % increase in nominal wage ={Increase in wage/ Wage in initial year} * 100
= {($77 - $70)/$70} * 100
= {$7/$70} * 100
= (1/10) * 100
= 10
Increase in CPI = CPI in 2020 - CPI in 2019
= 116 - 100
= 16
Since, Increase in CPI (16) is greater than % increase in wage (10). So I was better off earlier in 2019.
Because CPI rises at a faster rate than than the percentage increase in nominal wage so purchasing power of my wage declines as I am not able to cover up for Inflation by the increase in wage.
