CPC Calculator

What the CPC Calculator does

CPC Calculator turns a handful of paid search assumptions — cost per click, daily budget, click-through rate, conversion rate and average order value — into the numbers that actually matter for planning a campaign: expected clicks, impressions needed, conversions, cost per conversion, and estimated return on ad spend.

It's a planning tool, not a live data source: it runs the math on figures you provide, so the output is only as realistic as the assumptions you put in.

How to use the calculator

Enter your average CPC — what you expect to pay per click, or a figure from past campaign data.
Set your daily budget, expected click-through rate, and expected conversion rate.
Enter your average order value for the product or service being promoted.
Select Calculate to see daily clicks, impressions needed, conversions, cost per conversion, estimated revenue and estimated ROAS.

Where the numbers come from

Clicks per day is budget divided by CPC. Impressions needed is clicks divided by click-through rate. Conversions is clicks multiplied by conversion rate. Cost per conversion is budget divided by conversions, and estimated revenue multiplies conversions by average order value. ROAS compares that revenue to the budget spent.

Using it well

Run the numbers with a conservative CTR and conversion rate first, then with a more optimistic pair, to see the realistic range your campaign might land in rather than anchoring on a single best-case figure. If you have real data from a past campaign, use that instead of estimates — the output is only as useful as the inputs.

Usein kysytyt kysymykset

Where does the CTR and conversion rate data come from?

From whatever you enter — the calculator doesn't pull live industry averages. Use your own historical data where you have it, or a conservative estimate if you don't.

Does this account for Google Ads' Quality Score or auction dynamics?

No — it's a straightforward arithmetic model based on the figures you provide, not a simulation of the ad auction.

What's a realistic click-through rate to assume?

It varies enormously by industry and ad position — there's no single safe number. If you don't have your own data, start with a conservative estimate and see how sensitive your results are to it.

Can I use this for a non-Google ad platform?

Yes — the math is generic cost-per-click economics, so it works for estimating any paid-click campaign, not just Google Ads.

Does a higher ROAS always mean a better campaign?

Not necessarily — ROAS ignores profit margin. A high ROAS on a low-margin product can still be unprofitable once costs beyond the ad spend are factored in.
