Questions

About the Ad Budget Calculator

Can I check whether the budget is profitable?

Compare the ROAS shown with your break-even ROAS. If it is lower, the goal costs more in ads than the orders leave in margin.

Can I share the calculator with my team or a client?

Yes. The Room keeps the calculator live: anyone with the link can change the numbers and see the result update, with the method and assumptions on the same page.
