The advantage of SVG is that the graphics files are scalable. This has important implications.
As pages shrink and grow (perhaps when they are viewed on different devices, there is a risk that the image contained on that page will become blurred or distorted. Jpeg files for example really only want to be displayed at the resolution at which they were created. SVG files however can be re-sized up or down and yet they do not degrade. This is because they are defined mathematically and rendered by a parser into pixels rather than being rendered directly as pixels.
If you wish to decide which investment project is most worthwhile, then there are a number of means of ranking projects in a more or less robust way.
The payback period method or the payback rule as it is sometimes known calculates how long - if a given investment is made - it will take to equal and return the value of that original investment. For example if you invest £100 and receive weekly returns of £20, then after five weeks the investment is fully repaid, and any subsequent income is profit. We would say that the pay back period in this case is five weeks. If you have some idle cash for say six weeks, then the pay back period method may be the best choice as it attempts to get the best investment over a limited time scale - a time scale that perhaps fits in with other separate investment decisions. As a very simple investment-value calculator and has a number of advantages.
In the table below, try entering an initial investment and a series of returns to see what pbp is calculated.
The internal rate of return (IRR) assists capital budgeting decisions. It is calculated with this formula:
In the above table, set the rate to a value in the range 0 - 100 to get a net present value of around zero, and and thereby try to identify the internal rate of return . It may take many attempts. Also make sure the returns add up to more than the initial investment.
It is used to determine which discount rate makes the present value of anticipated cash flows equal to the initial capital investment, or in other words what must the investment return each year over the projects life such that it breaks even. This is equivalent to a net present value (NPV) of 0.
This is a little more sophisticated than the payback period concept as it takes into account the rate of return in each year.
