After watching your lecture working through the couple of examples you had on calculating the effective interest rate, I used the same examples to calculate the effective interest rate using a formula that the Kaplan text provides to calculate effective rates: r = (1+i/n)^n – 1, where r is the effective interest rate and i is the nominal one, n os the number of time periods. Using that formula to calculate the effective interest for example 4, the formula would have the following numbers: r = (1 + (0.02)/12)^12 – 1 which results in an effective rate of 0.02183 or 2.018% (compared to 26.82% in your answer). I’m assuming that the formula is correct and that I am missing something. Any chance you can spot my mistake?

The interest is 2% per month, and so the annual rate is 1.02^12 – 1 = 1.2682 or 26.82%
(You would only take 0.02/12 if 2% was the yearly rate)
Think about it – 2% per month could not possible be equivalent to 2.018% per year!!!

Im getting crazy now..now you multiplied 1.06 times 5 on calculator..Please give me the details.
December 12, 2014 at 8:03 am
On my calculator you type 1.05, then press ‘x’ twice, then press ‘=’ five times.
Might not be the same on all calculators though!
December 12, 2014 at 11:11 am
you are awesome, I was close to killing myself..: ) Thanks! Yes, I noticed it, sometimes I have another figure … If its acceptable than OK.

Hello Sir, can you please help me with this question?
Loan taken = £2,000
Interest reate = 10% per annum.
The person wishes to make equal monthly repayments comprising interest and principal, over 3 yrs starting one month after the loan is taken out.
What would be the monthly repayment on the loan?
Sir can you please explain how to calculate this?
August 8, 2014 at 7:52 am
I don’t know where you got this question from, but I would be very surprised if it would be asked in the exam!
First you need to calculate the interest rate per month. If the monthly rate is r, then
(1+r)^12 = 1.10. So r = 0.00797414 (or 0.797414%)
Then you need to calculate the annuity discount factor for 36 periods, using the formula.
Which is (1 – 1/((1.00797414)^36))/0.00797414 = 31.18646
The monthly payment will be the amount of the loan divided by this annuity factor:
2000 / 31.18646 = $64.13.
(You had better check my arithmetic )
Again, I would be very surprised indeed if this were to be asked in a real F2 exam.
August 12, 2014 at 7:52 am
Thank you Sir.
This is a question from past exam papers. Year 2002 No. 2.
Do you think we can still get such type of questions in future exams of F2?
August 12, 2014 at 8:00 am
You are welcome.
And no, although you are not wasting your time looking at the question, they do not ask that sort of question these days.
In 2002, Paper F2 did not exist – it was a different exam with a different syllabus (more statistical). Also, in 2002 there were no multiple choice questions, whereas now it is entirely multiple choice.

Sir, I’m also interested in this question due to nature of my job. How did u arrive at r=0.00797414? Also what is the formula used to get annuity factor 31.8646? Thank you
November 8, 2014 at 11:33 am
For the calculation of 0.00797414, as I wrote in the previous comment (1+r)^12 = 1.10, so 1+r = the 12th root of 1.10.
The formula for the annuity discount factor is printed at the top of the annuity factor tables that is provided in the exam.
November 8, 2014 at 2:51 pm
Okay sir…Thanks for the good thing u are doing
July 24, 2014 at 12:13 pm
Sir, what’s an ARR? and do you have any examples on this like the ones tested in the revision mock exam.

Accounting rate of return is average profit / average investment as a percent.
You should see the chapter (and the lectures) on investment appraisal for examples and explanation.
July 24, 2014 at 12:20 pm
i do not see any chapter of investment appraisal in the list of F2 lectures.
July 24, 2014 at 12:24 pm
Try chapter 21 in the Course Notes and the lectures that go with it

Hi admin I need your help
A Co adds interest monthly to investors’ accounts even though interest rates are expressed in annual terms. The current rate of interest is 6% per annum
An investor deposits $1000 on 1 Jan . How much interest will have been earned by 30 June?
The correct answer is $30.38
and I my answer is $ 30
November 17, 2013 at 4:12 pm
The interest is 6/12 = 0.5% per month,but it is compounding.
The amount owing in six months will be 1000 (1.005)^6 = 1030.38

What is the accepted rounding in terms of decimal places for ACCA exams?
September 26, 2013 at 5:48 pm
It depends on the question – there is no rule.
For example, usually if we are calculating unit costs then we round to the nearest cent. If we are calculating total costs then we usually round to the nearest $.
For Paper F2, the answers to choose from make it obvious what rounding (if any) is needed. (Or, if you are doing CBE and a question asks you to type in an answer then it will tell you ‘to the nearest $’ or ‘to the nearest $100′ or whatever.
In later exams where you have to write a full answer rather then just choosing one from four, then unless you are told different then it is usually to the nearest $ for total costs and the nearest cent for unit costs. (Although the markers are sensible – you don’t normally lose marks for rounding unless it is ridiculous)
September 26, 2013 at 5:50 pm
Because you put your question under the lecture on interest, for interest rates the choice of answers or the wording of the question will make it clear – sometimes it will be to the nearest % and sometimes it will be to two decimal places.

Thanks very much for this insight. Thanks again

i still haven’t gotten, what’s effective interest rate
March 1, 2013 at 3:12 pm
Thank you. OT the lectures helped me a lot it was my second sitting for F2. Today I passed my computer based exam.

Can you please explain this question?
Can you please explain this question taken from June 2012 exam paper?
An investor has the choice between two investments. Investment Exe offers interest of 4% per year compounded semi-annually for a period of three years. Investment Wye offers one interest payment of 20% at the end of its four-year life.
What is the annual effective interest rate offered by the two investments?
Investment Exe Investment Wye
A 4·00%n 4·66%
B 4·00% 5·00%
C 4·04% 4·66%
D 4·04% 5·00%
The correct answer is C.
November 25, 2013 at 9:42 am
Investment Exe annual effective return = (1+ 0.04/2)^2 – 1 = 0.0404 or 4.04%
Investment Wye annual effective return = (1+ 0.20)^0.25 – 1 = 0.0466 or 4.66%
March 27, 2014 at 1:06 pm
Ruby, could you write the common formula for annual effective rate? In course notes I found r = (1+i/n)^n -1, where r – effective interest rate,
i – nominal interest rate, n – number of time periods. But I am a bit confused, because according to the video lecture, the formula is without division into n (i/n)

Can you please explain this question taken from June 2012 paper?
An investment centre earns a return on investment of 18% and a residual income of $300,000. The cost of capital is 15%. A new project offers a return on capital employed of 17%. If the new project were adopted, what would happen to the investment centre’s return on investment and residual income?
Return on investment Residual income
A increase decrease
B increase increase
C decrease decrease
D decrease increase
The correct answer is D.
November 25, 2013 at 9:34 am
New project has ROCE = 17% >> This will make average ROI of the centre decrease
>>> Profit decreases, Investment increases
>>> Residual income (= Profit – Interest on investment) also decreases.
Hope that helps
November 25, 2013 at 9:39 am
Oh I made a mistake. The new project offer a return of 17%, higher than the cost of capital 15%, so the residual income will increase, not decrease.
November 25, 2013 at 11:01 am
Rubydinh’s final answer is correct
Since 17% is less than the current ROI of 18%, the ROI will decrease.
Since 17% is greater than the cost of capital of 15%, the RI will increase.

very good, and regarding multiply 100*(1.02) twelve time by calculator is easy, but any body let me know how can i give the formulla in excel sheet to do the same?
November 19, 2012 at 9:51 pm
@M. Osman Kamran,
September 4, 2012 at 1:38 am
the last question wasn’t half yearly….he said every two months, I dn’t think I grasp that last ques.
August 21, 2012 at 2:41 pm
oh okay for a year sorry.
August 21, 2012 at 2:40 pm
why is the 1.03 to the power 6 and not 2 in the last example? because you said every 2 months.
October 19, 2013 at 10:52 am
His reason for using 6 instead of 2 because it is every two months for one year which would be 6
August 9, 2012 at 5:07 pm
I don’t understand the logic with APR.
July 21, 2012 at 10:24 am
very good notes and thanks.
