How to solve this Forward Interest Rate question

Setup

Setup

The 6000 principal cancels when the two five-year repayment amounts are equated.

(1.0725)5=(1.0575)3(1+f)2(1.0725)^5=(1.0575)^3(1+f)^2

Model

Model

Isolate the two-year forward accumulation factor.

(1+f)2=(1.0725)5(1.0575)3(1+f)^2=\frac{(1.0725)^5}{(1.0575)^3}

Compute

Compute

Take the positive square root and subtract one.

f=[(1.0725)5(1.0575)3]1/21=0.0953999f=\left[\frac{(1.0725)^5}{(1.0575)^3}\right]^{1/2}-1=0.0953999

Answer

Answer

The two-year loan must charge 9.54% annually, choice D.

f9.54%(D)\boxed{f\approx9.54\%\quad\text{(D)}}
