Hi everone, I'm sorry to invade your e-space as I am nowhere near the intellectual level of you guys when it comes to maths!

However I do have a question and I thought as u guys are the Canines Testicles at this sort of thing, one of u would know the answer and be able to communicate it in a way I can grasp (hopefully) but if that is not possible maybe u can provide the formula which returns the value I am querying...any help would be truly appreciated.

Heres the info,

I have a period of time - 1 to 36 Months.

In each of those Months (1 to 36) I have a single value which represents the loss in value due to depreciation over the period.

This is represented by incresing currency values (£). For Example

Month 1= 500

Month 2 = 750

Month 3 = 800....etc etc

A cummulative monthly curve over 36 months based on the overall distribution of these values adding up to 100% produces a factor of 0.6. If you adjust this value it adjusts the curve.

My problem is that I do not know why any changes are represented by a decimal number - i.e. what does 0.6 mean when applied to a curve? is it the deviation from 1? and if so does 1 represent a true average?

I can provide an excel version of what I mean if it helps

As I said O Levle maths is my limit so if any of this seems idiotic I apologise and bow to your superior knowledge but could really use the help anyhow...

Cheers

Steve
