I am writing up a cost sheet for a product and I basically suck at math. Didn't know who else to turn to, so trying out Math exchange.
So, I am planning to spend
$1,100 every month on advertising that will bring me
$130 of additional cumulative revenue every month. Basically, it will bring me new clients that I charge $130 every month in addition to existing clients. So cost is fixed monthly, but revenue is cumulative.
How do I calculate when my cost v/s revenue breaks even, and my profit from thereon?
If I put this up on a spreadsheet, it looks something like this:
Month | Revenue | Cost
1 | 130 | 1100
2 | 260 | 1100
3 | 390 | 1100
4 | 520 | 1100
5 | 650 | 1100
6 | 780 | 1100
Total After 6 months:
