The calculators only do arithmetic on the figures you give them.
Replace every example number with your own: revenue and spend from your Google Ads account, margin and order value from your accounts. An answer is only as good as the numbers you put in.
Each card prints the sum it does in plain English, so you can check it by hand or in a spreadsheet. The projectors repeat a steady monthly rate and ignore seasonality, so treat them as illustrations.
Break-even ROAS tells you the line, your real ROAS shows where you stand against it, and the budget planner shows what your cost per click and conversion rate imply. If you want a second pair of eyes on the real account, ask for a free audit.
Google Ads calculator FAQs
ROAS is return on ad spend: the revenue your ads brought in divided by what you spent on them, shown here as a percentage. If your ads bring in five times what you spent, that is a ROAS of 500%.
Divide the revenue from your ads by your ad spend and multiply by 100 to get a percentage. The return on ad spend calculator above does it as you type.
Break even ROAS is the return at which a sale pays for its own advertising and leaves nothing over. It is 100 divided by your profit margin, as a percentage of spend: a 25% margin gives a break even ROAS of 400%. Above it you make money on the sale, below it you lose money.
Not on its own. ROAS counts revenue, not profit, so a high ROAS on a low-margin product can still lose money. Compare it with your break even ROAS rather than with a general figure.
Profit is the money left after costs. Profit margin is that profit as a share of sales. The profit margin calculator shows both, and the margin feeds the break even ROAS calculator.
Start from the enquiries you want, divide by your conversion rate to get the clicks you need, then multiply by your cost per click. The budget calculator also works the other way, from a budget to the clicks and enquiries it implies. You supply the cost per click and conversion rate, because only your own account knows them.
Cost per lead is your spend divided by the enquiries you got. Cost per sale is your spend divided by the sales you won. The gap between them is your lead to sale rate, which the cost per lead calculator shows when you enter your sales.
It is what a customer is worth to you over the whole time they buy from you. Knowing it tells you how much of the lifetime profit you could spend winning a customer, which is often more than the profit on the first sale.
It shows what a higher conversion rate would be worth on the visitors you already have. It does not say a higher rate can be reached; testing on your own website is how you find out.
No. The sums are done in your browser and the numbers you enter stay there. We only count that a calculator was used.
No. They repeat one steady monthly rate for the months you choose. Real months move with seasonality, budgets and competition, so use them as an illustration.
