What formula do you use to calculate the payback period?

Payback analysis compares the cumulative costs and benefits of a proposed information system to determine how long it will take for the system to pay for itself. This period of time is called the payback period. Cumulative costs include developmental and operational expenses, and benefits include all tangible benefits.
A payback period is the time it takes for the accumulated benefits of an information system to equal the accumulated costs of developing and operating the system. You can use a chart or a spreadsheet to calculate the payback period. Either way, to calculate the payback period, you must perform the following steps:
1) Determine the initial development cost of the system.
2) Estimate annual benefits.
3) Determine annual operating costs.
4) Find the payback period by comparing total development and operating costs to the accumulated value of the benefits produced by the system.
When using a graph, such as the example shown in Figure C-3, note that the payback period is not the point when current benefits equal current costs, where the two lines cross. Instead, the payback period compares accumulated costs and benefits. If you graph current costs and benefits, the payback period corresponds to the time at which the areas under the two curves are equal. If you use a spreadsheet program to calculate the cumulative cost-benefit data, as shown in the examples in Figure C-5, you can estimate the point in time where the cumulative benefits exceed the cumulative costs. Note that year 0 (zero) is the year in which systems development begins.

Rewrite myname from the previous step, calling it myname2. Have this ver- sion of the program prompt the user for a string, but instead of displaying Hello and the string on the screen (sending it to standard output) redirect the output so the program writes only the string the user entered (and not Hello) to the temporary file named PID.name where PID is the process ID number (Sobell, page 480) of the process running the script. Display the contents of the PID.name file.
