Estimate Google Ads clicks, conversions and revenue
Plan Google Ads performance from budget, CPC, conversion rate and average order value.
Scenario: Budget / CPC = clicks; clicks x conversion rate = conversions; conversions x order value = revenue.
How to use the Google Ads budget calculator
Enter a monthly budget, average CPC, conversion rate and average order value. The tool estimates clicks, conversions, CPA, revenue and ROAS as a planning scenario.
Google Ads planning formulas
Clicks = Budget / CPC. Conversions = Clicks x conversion rate. Revenue = Conversions x average order value. ROAS = Revenue / Budget.
Example: $3,000 budget, $1.50 CPC and 4% conversion rate
The scenario estimates about 2,000 clicks and 80 conversions. At an $80 average order value, estimated revenue is $6,400 and ROAS is about 2.13x.

| $5,000 | 5,000 | 2,500 | 150 | 250 |
| $10,000 | 10,000 | 5,000 | 300 | 500 |
What can change Google Ads results?
Actual CPC and conversion rates vary by keyword, competition, match type, device, geography, landing page, bidding strategy and conversion definition. Treat this as a scenario planner rather than a forecast guarantee.
Frequently asked questions
Does the calculator use Google Ads API data?
No. It uses only the values you enter.
Is average CPC stable?
No. CPC can vary substantially across queries and auctions.
What if I generate leads instead of sales?
Use expected value per lead instead of average order value if you want a revenue-style planning model.
Is ROAS the same as profit?
No. ROAS compares revenue with ad spend and does not include product margin or operating costs.
