Enter your assumptions to see the projection and the figures behind it.
How this calculator works
Enter the conversions you want each month, the rate at which clicks convert, and what you expect to pay per click. The calculator works back through the clicks required to the monthly and daily budget, and shows the cost per conversion that implies.
The formula
Clicks needed = Target conversions ÷ (Conversion rate ÷ 100). Budget = Clicks × CPC. Daily budget = Monthly budget ÷ 30.4. Implied CPA = Budget ÷ Target conversions.
Worked example
To win 50 conversions a month at a 3% conversion rate you need about 1,667 clicks. At $4.50 a click that is roughly $7,500 a month, or $247 a day — an implied $150 per conversion.
How to read your result
Every rate here is one you supplied, so the output is only as good as those assumptions. Use Keyword Planner for a CPC estimate and your own analytics for conversion rate. Then treat the result as a starting budget to test, not a forecast.
Questions
Where do I find my expected CPC?
Google Keyword Planner gives estimates for your keywords, or use your own account history. Expect real CPCs to differ, particularly early while Quality Score settles.
What if I do not know my conversion rate?
Run a small test budget first and measure it. Guessing this number is what makes a budget plan worthless, because the whole calculation pivots on it.
Should I start at the full budget?
Usually not. Start smaller, verify the rates hold, then scale. The maths assumes performance stays constant as you spend more, which is rarely exactly true.
