Free to use. The calculations respond to the values you enter.
CPC and budget calculator
Works both ways: what a budget returns in clicks and orders, or what a given number of clicks will cost. Includes CPC to CPM conversion.
Open calculator ↗02 / CalculatorGoogle Ads budget calculator
Work out the most a click can cost and the monthly budget Google Ads needs, from your order value, margin and conversion rate.
Open calculator ↗03 / CalculatorBreak-even ROAS calculator
Find the ROAS where advertising breaks even — calculated from price, cost of goods and return rate rather than from a margin you have to guess.
Open calculator ↗04 / CalculatorCAC and payback calculator
Work out what a new customer costs, what she is worth over her lifetime, and how many months it takes before she has paid for herself.
Open calculator ↗05 / CalculatorContribution margin calculator
Work out contribution 1, 2 and 3 for an online shop: after cost of goods, after variable order costs, and after marketing.
Open calculator ↗06 / CalculatorUTM builder
Build tracking links that do not break your reporting. Values are normalised automatically, so Facebook and facebook do not become two sources in GA4.
Open calculator ↗07 / CalculatorIncremental ROAS calculator
Put what the channels claim next to what the shop actually made. See what your ROAS becomes when only the incremental part counts.
Open calculator ↗What do I get out of my ad budget?
Enter a budget and see the whole chain: the market-average CPM gives your impressions, the click rate your clicks, the conversion rate your orders — and so your expected revenue, ROAS and POAS. Switch industry preset or adjust each number with your own.

After ads
€4,000
A POAS above 1 means the ads pay for themselves at gross level. Whether it turns a profit depends on your fixed costs.

CLTV calculator
What a customer is worth over their lifetime — and therefore how much you can afford to pay to win one (CAC).

Annual customer value

CAC at an illustrative 3:1 ratio
€60
A 3:1 ratio gives a CAC of €60. It is a scenario, not a universal target; assess payback, fixed costs and uncertainty.
Linear illustration with constant contribution per purchase. Actual purchase timing, returns and customer churn can change the outcome.
The default values are international e-commerce averages from 2025 (including WordStream and Triple Whale), converted to euros. Meta is billed per impression (CPM), Google Search and Shopping per click (CPC). Your country and your specific industry can differ significantly — so adjust the fields with your own numbers for an accurate estimate.
