Ad budget for target orders.
Enter how many orders you want and your cost per order, or your CPC and conversion rate. See the budget, clicks needed, a daily budget and the profit or loss at your margin.
Budget = target orders x cost per order (CPA). 100 orders at a $24 CPA needs $2,400; if CPA is not known, use CPC / conversion rate, for example 0.72 / 3% = $24.

Worked example
You want 100 orders. Clicks cost $0.72 and 3% of clicks buy, so CPA = 0.72 / 0.03 = $24 and the budget = 100 x $24 = $2,400. You need 100 / 0.03 = 3,334 clicks. Over 30 days that is $80 a day. On $60 orders the revenue is $6,000, ROAS is 2.5x and at a 40% margin profit after ads is $0, exactly break-even.
How it works
Budget = target orders x CPA. Google Ads defines average CPA as the average amount charged for a conversion. If you do not know it, this tool derives CPA as CPC / conversion rate.
Clicks needed = orders / conversion rate, rounded up. Daily budget = budget / days. ROAS = revenue / budget. Profit = revenue x margin - budget.
This assumes your CPC and conversion rate stay constant as spend rises. In practice, costs often rise as you scale and audiences saturate, so treat the result as a planning estimate and not a guarantee.
Enter your own measured CPA, CPC and conversion rate. This tool does not supply benchmarks.

FAQ
How do I calculate how much to spend to get 100 orders?
Multiply 100 by your cost per order. If you only know CPC and conversion rate, divide CPC by the conversion rate first.
Will my cost per order stay the same at a bigger budget?
Often not. Scaling spend can push CPC up and conversion rate down, so test in steps and update the inputs with real results.
What if I enter both CPA and CPC?
The CPA you enter is used. CPC and conversion rate are then used only to estimate clicks needed.
Does the result include repeat orders?
No. It is the budget for that number of orders and the first-order profit at your margin.
