inflation rate calculator chart.

I need someone who can create a spreadsheet that allows a certain number to be put in and than show a certain percent increase than what that number increasing at that rate per year would be at 5, 10 ,15, 20 and 25 years. it is going to be used in selling people solar showing them that the current rates of electric continue to go up year after year and if they don't switch to a fixed rate in solar than what they can expect to see as the years go by. I just want it where you can see five colums simultaneously where I can plug in the start number and the rate increase and it changes the five values. Ideally I would like this calculator to work on smart phones where I can take a screen shot and text it.
