Caluclating interest on a loan - help (can/will pay)!!

Hi,
I have a client who has a business loan from a private individual, who has agreed an interest rate of, say 4% over base. They have told my client to calculate the interest themselves.
I know the formula is hideously complex and I have no practical knowledge of it. I am not confident in being able to explain how do do it or indeed of getting it right!
Also, surely my client could choose to pay based on either a daily rate, or balance outstanding at the end of every month/quarter/year? The loaner has said it's up to her to caluclate it. Loan is repayable quarterly.
Is it simply a case of, say:
Loan taken out January
2nd payment in March, balance outstanding £19000
Interest = 19000 * (4.5% x 1/4)
Plus the capital repayment of, say, £500
i.e. charging a quarter of a year's interest on that quarter's payment
Payment in June
Bal outstanding (19000-500)
Interest = 18500 * (4.5% x 1/4)
Plus capital repayment of 500
etc
??
Client happy to pay someone to work it out and provde a spreadsheet to work it out going forwards, including the possibility of changing interest rates etc.....
Thank you!

Ok, so having read this thread, I didn't get it right. I hope someone can help! My tiny brain can't cope!0

I'm sure someone with more loan experience will advise, but it is like the other thread you mention, in that you have to decide if the interest is compounded or not. In this case I wouldn't imagine it is supposed to.
You need a spreadsheet with 3 columns; loan - interest - total
Then you can work out the interest daily, monthly or quarterly, but keep it in a seperate column so its not compounded.0 -
Thanks PGM. Maybe it isn't as complex as my little brain thinks.
What is the practical difference between compounded and not? Obviously I see why savings interest that gets added to the account balance gets subject to compound interest (hooray!) but I'm not so clear on why loan interest would get compounded.
Is the logic that in future years they will owe interest that they haven't paid yet and so they are paying interest on that as well, i.e. compounded?0 -
With the compound method as Crispy mentioned on the other thread you'd work out 4.5% to the 12th root.
Which would be 1.003675% monthly on total balance.
I think we need someone with more loan experience, any bankers?!0 -

Why don't you use PMT formula in the spreadsheet.
Given the loan amount, £19000
interest rate, (0.5+4) =4.5%
Length of Loan = 20 ( 5years times 4 qts)
gives a qtly payment of £1066.19
Formula = PMT((4.5/4),20,£19000)
Note 4.5% is divided by 4 for a quarter (12 for monthly payments)
20 = length of loan
The interesting thing of the above formula is you can change any variable to suit your needs
If you want the spread sheet just PM me your e-mail
hope this helps0 -
or use the loan amortization spread sheet template in excel?
great for showing a complete breakdown of the capital element and interest element of a loan0 -

Thats a handy spreadsheet! The blood pressure tracker is a bit of an odd one...
Going back to Monsoons original question, with it being a add hoc type loan? How do you treat the interest?0 -

I've been playing round with spreadsheets and loan amounts. This template/compound interest does give the more meaningfull figures!0 -
Thanks guys.
My brain just doesn't get this stuff, especially how to calculate the initial payment (but my client has used various loan calculators online and they all come out with the same answer, so I guess that's right). I really, really don't want to advise her on this stuff as it's way outside what I'm comfortable doing. I like to think I'm pretty intelligent and good at what I do, but I feel like an utter thicko with this!
Where are the templates in excel? I didn't know they had any...
PGM, PM incoming...!0 -
depends which version of excel your using?
but i think on 2007 its when you go to new file you select templates, if its not there you can download from the excel online templates

Yes I'm on 2007.
Look at that! Isn't that clever!! OOOhhhh!!!
And the loan amortization one works perfectly, thank you both!!with it being a add hoc type loan? How do you treat the interest?0 -

I remember working out loan interest in maths classes at school - could do it back then but wouldn't like to try it now! The compounding bit is how often the interest is added isn't it? so if you had a loan at 5% compounded weekly you'd pay more than if it was compounded monthly as you'd be paying more interest on the interest that's already been added. But that's about all I can remember!0

That's what was throwing me, but no! The compounding should take this into account and get you to the same answer. Actually the more periods and he sooner you might take into any repayments sooner, and reduce interest payments.0
