To find the initial value of the loan, we can use the formula for the present value of an ordinary annuity:
PV = \frac{P}{r} \left(1 - \frac{1}{(1+r)^n}\right)
where:
- PV is the present value or initial value of the loan
- P is the payment amount made at the end of each period (monthly)
- r is the interest rate per period (semi-annually)
- n is the total number of periods (monthly payments for 12 years = 12 * 12 = 144 periods)
First, let's convert the interest rate from annual to semi-annually:
r = \frac{5.2}{2} = 2.6\% = 0.026
Now we can calculate the initial value of the loan using the given values:
PV = \frac{2226}{0.026} \left(1 - \frac{1}{(1+0.026)^{144}}\right)
Simplifying the equation:
PV = \frac{2226}{0.026} \left(1 - \frac{1}{(1.026)^{144}}\right)
Calculating the present value:
PV=\frac{2226}{0.026}\left(1-\frac{1}{(1.026)^{144}}\right)\approx83.475
Therefore, the initial value of the loan is approximately 83.475
