Ad Budget Calculator
Estimate the clicks, conversions, and cost per conversion your ad budget will buy at a given CPC.
Clicks are your budget divided by the average cost per click; conversions apply your conversion rate to those clicks. The same budget at a low CPC buys a lot more traffic than the same money at a high CPC — so bidding on cheaper, tighter keywords often stretches further.
How it works
Start with a budget — daily or monthly — and your average cost per click. Divide the budget by the CPC and you get roughly how many clicks you can expect. A $3,000 monthly budget at $1.20 per click, for example, buys around 2,500 clicks.
Add a conversion rate and the tool takes it a step further: it applies that rate to your estimated clicks to project conversions, then divides your spend by those conversions to show cost per conversion (CPA). That's the number that tells you whether the campaign math actually works.
Because everything keys off averages, treat the output as a planning estimate. Real CPC swings with competition and quality score, and conversion rates move with your landing page and offer. It's most useful for comparing scenarios — cheaper keywords versus pricier ones, or a bigger budget versus a smaller one.
Frequently asked questions
What's CPC and where do I find my average?
CPC is cost per click — what you pay each time someone clicks your ad. Your ad platform reports an average CPC for past campaigns; if you're just starting, use a keyword tool's suggested bid as a rough stand-in.
How is cost per conversion calculated?
It's your total spend divided by the number of conversions. If you spend $3,000 and get 100 conversions, that's a $30 cost per conversion — a quick way to judge whether the campaign pays off.
Why are my real numbers different from the estimate?
Averages hide a lot of variation. Actual CPC changes by keyword and competition, and conversion rate depends on your offer and landing page, so live results will drift from any upfront estimate.
