Future value = Present Value (1 + r) n

=38689.42 x 1.95
=75444.37
Working Notes:
1. Calculation of interest for the 1st year
Given that the interest is received at 4%. Therefore, the amount of interest received will be:
Interest received
= Principal amount x Rate of interest
= 11132 x 4%
=445.28
2. Calculation of interest for 2nd year
Interest received
= Principal amount x Rate of interest
= 6230.28 x 4%
= 249.22
3. Calculation of interest for 3rd year
Interest received
= Principal amount x Rate of interest
=12264.5 x 4%
=490.58
4. Calculation of interest for 4th year
Interest received
= Principal amount x Rate of interest
= 18540.08 x 4%
=741.61
5. Calculation of interest for 5th year
Interest received
= Principal amount x Rate of interest
=25066.69 x 4%
=1002.67
6. Calculation of interest for 6th year
Interest received
= Principal amount x Rate of interest
=37201.36 x 4%
=1488.06
7. Calculation of future value of the amount after 23 years compounded annually at 4%
Future value = Present Value (1 + r) n
=38689.42 (1 + 4%) 17
=38689.42 x 1.95
=75444.37
The n denotes the number of years. It is calculated as:
The current year is 2019. We have to find 23 years from this year. That is:
2019 + 23 = 2042
The account prepared shows the value upto 2025
So, n will be 2042 - 2025 = 17
This is how n = 17
