Standard S Curve - Insert Duration and Total Cost to Predict Cash Flow

Has anyone ever created a standard S curve in which you could then insert a project duration and total budget to predict future cash flow?

I am looking for something very rudimentary, with full understanding that there will be great variance between this "predicted" S curve and actual S curve. The tool would be used in very early stages of a project (precon) to allow Owners to predict what their cash flow ill be months/years down the line. Hope this makes sense.

Thanks in advance for your help.
