Answer:
19.20%
Step-by-step explanation:
For computing the effective annual rate first determine the rate of interest which is shown below;
Given that
NPER = 12
PMT = $90
PV = $1,000 - $25 = $975
FV = $0
The formula is shown below:
= RATE(NPER;PMT;-PV;FV;TYPE)
The present value comes in negative
After applying the above formula, the rate of interest is 1.6097%
Now the effective annual rate is
= (1 + Monthly Interest Rate)^12 - 1
= (1 + 1.6097%)^11 - 1
= 1.016097^11 - 1
= 1.1920291076 - 1
= 19.20%
