Here's how to calculate the future value of the annuity for each period.
The formula for the future value of an ordinary annuity is:
FV=Pmt×i(1+i)n−1
Where:
- FV = Future Value
- Pmt = Payment per period = 1,000,000
- r = Annual interest rate = 5%=0.05
- m = Number of compounding periods per year = 2 (semi-annually)
- i = Interest rate per period = mr=20.05=0.025
- t = Number of years
- n = Total number of periods = m×t
a) 3 years
Step 1: Identify the parameters.
Pmt=1,000,000
i=0.025
t=3 years
n=2×3=6 periods
Step 2: Substitute the values into the formula.
FV=1,000,000×0.025(1+0.025)6−1
Step 3: Calculate the term (1.025)6.
(1.025)6≈1.159693
Step 4: Calculate the future value.
FV=1,000,000×0.0251.159693−1
FV=1,000,000×0.0250.159693
FV=1,000,000×6.38772
FV=∗6,387,720.00∗
b) 6 years
Step 1: Identify the parameters.
Pmt=1,000,000
i=0.025
t=6 years
n=2×6=12 periods
Step 2: Substitute the values into the formula.
FV=1,000,000×0.025(1+0.025)12−1
Step 3: Calculate the term (1.025)12.
(1.025)12≈1.344888
Step 4: Calculate the future value.
FV=1,000,000×0.0251.344888−1
FV=1,000,000×0.0250.344888
FV=1,000,000×13.79552
FV=∗13,795,520.00∗
c) 10 years
Step 1: Identify the parameters.
Pmt=1,000,000
i=0.025
t=10 years
n=2×10=20 periods
Step 2: Substitute the values into the formula.
FV=1,000,000×0.025(1+0.025)20−1
Step 3: Calculate the term (1.025)20.
(1.025)20≈1.638616
Step 4: Calculate the future value.
FV=1,000,000×0.0251.638616−1
FV=1,000,000×0.0250.638616
FV=1,000,000×25.54464
FV=∗25,544,640.00∗
