Is Google Ads worth it for you?
Move the sliders to your numbers and see instantly what a new customer costs you, when you start making a profit and where the biggest lever sits — in plain language, no marketing jargon.
Your numbers
Estimates are fine. Don't know them? Use the defaults — in the intro call I'll look at your real account data with you.
What you pay per click on average. Local service businesses: often €1–6.
How many visitors become an enquiry. Solid pages: 3–10%.
How many enquiries you turn into paying customers.
Revenue per won customer (incl. follow-up orders if any).
What's left after material/external costs. This decides real profit.
Profitable ✅
A new customer costs €200, your break-even is €320. You're making money — with clean tracking and optimization there's usually more.

Break-even CPA: €320.00 — the most a new customer may cost before you lose money.
Break-even ROAS: 2.5× — from here you are in profit (derived from your margin, not the revenue ROAS).
What do these metrics mean?
CPC — Cost per Click
What you pay on average for a click on your ad. Drops with a better quality score (relevant keywords, ads and landing page).
Conversion Rate (CR)
Share of visitors who become an enquiry. The biggest lever often sits here — not in the budget, but on the landing page.
CPL — Cost per Lead
What an enquiry costs you: budget ÷ enquiries. Good for comparing campaigns — but says nothing about enquiry quality yet.
CPA — Cost per Acquisition
What a paying new customer costs: budget ÷ new customers. The key number. As long as CPA is below your break-even CPA, you make money.
ROAS — Return on Ad Spend
Revenue per €1 of ad budget. ROAS 4× means €4 revenue per €1 of ads. Note: ROAS measures revenue, not profit.
Margin & break-even
Only margin decides profit. Break-even ROAS = 100 ÷ margin %. At 40% margin you need at least ROAS 2.5× to cover costs.
This is a model with your estimates — not a promise. Real accounts have fluctuations, seasonal effects and learning phases. That's exactly what I look at with you in the intro call.
Frequently asked questions
- Do I need my real numbers?
- No. Estimates are enough to get a feel for it. The default values are realistic benchmarks for local service businesses. For numbers you can rely on, I look at your account together with you.
- What is the most important metric?
- The CPA — what a paying new customer costs you. As long as it stays below your break-even CPA (order value × margin), you make money with Google Ads.
- Why is a high ROAS not enough?
- ROAS measures revenue, not profit. Only your margin decides at which ROAS you are truly profitable. That is exactly what the tool factors in.
- My result is negative — does that mean Google Ads is not for me?
- Usually not. Negative results almost always come from a CPA that is too high (wasted spend, wrong search terms) or a weak landing page — both can be fixed.
