How are the future salaries determined?
The future salaries (values) can be determined using an online finance calculator that compounds with the sum of the average inflation rate of 2% and the cost-of-living raise of 2% for 11 and 21 years, respectively.
Data and Calculations:
Future Value in 11 years:
N (# of periods) = 11 years
I/Y (Interest per year) = 4% (2% x 2)
PV (Present Value) = $41,000
PMT (Periodic Payment) = $0
Results:
FV = $63,117.62 ($41,000 + $22,117.62)
Total Interest = $22,117.62
Future Value in 21 years:
N (# of periods) = 21 years
I/Y (Interest per year) = 4% (2% x 2)
PV (Present Value) = $41,000
PMT (Periodic Payment) = $0
Results:
FV = $93,429.49 ($41,000 + $52,429.49)
Total Interest = $52,429.49
