What is the Ad Budget & ROAS Calculator?
This calculator walks an ad budget through your funnel: clicks from the cost per click, leads from the landing page conversion rate, customers from the lead-to-customer rate, then revenue and ROAS. Read ROAS against your own margins: a value is only profitable if it exceeds your break-even ROAS.
How it works
Clicks = budget / cost per click. Leads = clicks x landing page conversion %. Customers = leads x lead-to-customer %. Revenue = customers x average order value. ROAS = revenue / budget. Cost per lead = budget / leads. Every division returns zero when the divisor is zero.
How to use it
- Enter the monthly ad budget you plan to spend.
- Add your expected cost per click and landing page conversion rate.
- Enter the share of leads that become customers and your average order value.
- Compare the ROAS with your break-even ROAS before committing the budget.
Ad Budget & ROAS Calculator — FAQ
Where do I get the funnel percentages?
Use your own analytics, CRM or past campaign reports. If you have no history, run a small test first and replace the guesses with real numbers.
Is this a forecast?
No. It is arithmetic on the assumptions you type in. Real results change with creative, targeting, season and competition.
What if I sell on repeat orders?
Use the average order value for the first purchase here, then work out lifetime value separately to see the longer-term return.
