# Revenue and cost calculations based on timing of rollout criteria

Based on the month that we will rollout our services to particular companies, I need to calculate how much we will be making in revenue and the cost associated with the deployment of hardware.  The month of the rollout will be the variable that may change so the revenue and costs all need to be tied to this variable.

Revenue:
For each company, revenue will be ongoing after each rollout.  Meaning if we rollout on Month 6 then we will continue our revenue stream on an ongoing monthly basis.  Row 26 in the attached spreadsheet will reflect the total revenue for all companies.

Cost:
The cost is for hardware at rollout and an accrual for ongoing replacement.  The cost is \$1k per car in the month of rollout plus \$750 for every 20 units that have already been deployed.  Look at:
Row 7 - Car installs - this identifies how many units will be installed based on the month of rollout
Row 8 - Total # of cars - this is a cumulation of all units installed
Row 27 - this is the cost based on \$1k per car in the month of rollout plus \$750 for every 20 units

I highlighted in yellow the cells that I would need you to calculate (again based on the variable month of rollout).  I manually input the amounts to show what they will need to be.

please let me know if you have any questions.

I also would like to be able to change the cost (charge) at any time going forward.  I imagine I would have to create a new column with the exact info but changing row 24

Not sure I understand exactly what you are going for here... can you post another sheet, what it would look like if Rollout Month is set to 3?

Hi there, I added a new tab and highlighted in green everywhere the change to month 3 rollout effects.  Let me know if you need more clarification

I updated the values  in Row 11...
so for example instead of Month 1  |  Month 2 | Month 3
it now contains values of 1 | 2 | 3 etc.

That allowed the formulas I added to easily check if I was less than or equal to a particular month.

If that formatting is not acceptable, there are some alternatives... but this approach is the easiest.

If you change the values in cells B11 through H11, you should see your other totals updated as well.

Works great.  Can I extend my question?  In playing with it, I realize that the variables (% adoption, price, etc) may change after a certain period of time.  So can you work in start AND end months into the equation?  Then I'll add additional columns to show the new variables.

Or should I start a new question for this?

Thanks,
Janice

If you agree that my answer is correct for the question you asked, I'd prefer to be awarded the points for correctly answering your question...

If you want to expand with another question, I'd be happy to take a look and see if I can answer that as well.
