AdsMath V2
The number your ad dashboard leaves out
YOUR ROAS LOOKS GOOD.
YOUR BANK ACCOUNT DISAGREES.
Before you scale another “winning” campaign, find out how much you can actually afford to pay for an order.
AdsMath puts your traffic cost, conversion rate, order value and margin into one calculation. You see the ad cost you can afford—and what’s left after the ads are paid.

If you know your ROAS but not what’s left, you’re missing the decision.
Sound familiar?
The dashboard says “scale.” Your margins say “stop.”
You spent money. Orders came in. Meta shows a respectable ROAS. It feels like proof that the campaign is working.
Then the supplier bill arrives. Shipping costs more than you expected. Returns eat into the month. There’s revenue on the screen, but surprisingly little left to keep.
A sale is not the same thing as money left after the sale.
ROAS tells you how much revenue came back for your ad spend. It doesn’t know your product cost, shipping, fees, returns or what you need to keep after acquiring the order.
That’s how a “good” ROAS can still be bad business.
Look at this
Same 3× ROAS.
One store wins.
One loses.
Both stores spend €1,000 on ads and bring in €3,000 in sales. Their dashboards show the exact same result.
Illustrative example · same reported ROAS
Store AStore B
Revenue€3,000€3,000
Ad spend€1,000€1,000
Margin before ads40%25%
Left after ads+€200−€250
That’s a €450 difference the ROAS figure does not explain.
This is a simplified first-order example. It excludes fixed overhead, taxes and any later purchases.
The question is not “Is my ROAS good?”
It’s “Good for which margin?”
It’s “Good for which margin?”

The missing number
How much can you actually pay for an order?
Start with the average value of an order. Take out the variable costs tied to that sale. What remains before advertising is your contribution.
That contribution sets the ceiling for acquisition. Spend all of it on ads and there’s nothing left from that first order before overhead. Spend more and you’re below that simplified break-even point.
Your platform cannot set this ceiling for you. It doesn’t know your margins.
AdsMath makes the ceiling visible. Then it lets you compare it with the ad cost implied by your traffic price and conversion rate.
Here’s how AdsMath works
Five inputs.
The decision gets clearer.
01 Your ad spend
02 Your cost per click
03 Your conversion rate
04 Your average order value
05 Your contribution margin
The online Simulator estimates clicks, orders and revenue. Then it puts your modeled ad cost per order next to your maximum allowable ad cost per order and shows the estimated amount left after ads.
Change a number. Watch what happens. Find out whether cheaper traffic, a better conversion rate, a higher order value or stronger margin would move the result.
Don’t know your margin yet? Use the helper to work through product cost, shipping, other variable costs and returns.
The point
Stop treating a campaign metric like a business answer.
Meta and Google Ads are useful. So is Shopify. But their dashboards answer different questions. You still have to connect the cost of getting an order with what that order contributes.
AdsMath is a quick first-order model for doing that. It won’t run your accounts, pull live data or make decisions for you.
It gives you the math you should have in front of you when you make the decision.
The complete package
Get the number.
Understand what to do with it.
The Simulator shows you the economics. The Decision Guide PDF explains the levers behind them: traffic cost, conversion rate, average order value and contribution margin.
Use it when you’re setting a cost-per-purchase target, deciding whether to raise spend, or explaining why sales are growing while the money left behind isn’t.

Who made this?
I buy ads for a living. I still start with the math.
I’m Florian Coman, founder of Scaling ROAS. I’ve worked in advertising for more than 20 years and managed millions in ad spend.
After enough campaigns, the same problem keeps showing up: people debate ROAS before they know what an order can afford to cost.
So I built a simple way to put those numbers together. That’s AdsMath.
Ads don’t fix weak math.
Quick answers
Questions before you check out?
Do I connect Meta, Google Ads or Shopify?
No. You enter your own figures. You can see the calculation and test scenarios without connecting an account.
Will AdsMath tell me which campaign to pause?
No. It models your numbers and shows your estimated ad cost per order, allowable ceiling and amount left. Use your account data and judgment to make the campaign decision.
Is this only for Meta ads?
No. It applies to paid traffic for ecommerce whether it comes from Meta, Google or another platform.
What if I don’t know my contribution margin?
The Simulator includes a helper for product cost, shipping, other variable costs and returns.
Is €49 recurring?
No. It’s a one-time payment for the online Simulator and Decision Guide PDF.
