About the PPC Campaign Forecast Calculator
This PPC forecast calculator turns a budget into a full projection. Clicks are budget divided by average CPC. Conversions are clicks multiplied by conversion rate, and revenue is conversions multiplied by average order value. ROAS is revenue divided by budget, CPA is CPC divided by conversion rate, and profit after ad spend is revenue multiplied by gross margin minus the budget.
Use it to sanity-check a plan before you commit spend, or to show a client or manager how changes in CPC or conversion rate affect the bottom line. If the forecast shows a loss, the verdict suggests which levers to pull. Remember that forecasts are estimates and real auction prices vary. Figures stay in your browser.
How to use it
- Enter your monthly budget and expected average CPC.
- Add conversion rate, average order value and gross margin.
- Review projected clicks, conversions, revenue, ROAS, CPA and profit.
- Try different CPC or conversion rate values to see best and worst cases.
Frequently asked questions
How accurate is a PPC forecast?
A forecast is only as reliable as its inputs. CPC, conversion rate and order value all change with competition, seasonality and the quality of your ads and landing pages. Use recent data from your own account where possible, and build a low, expected and high scenario rather than one number.
Why does the forecast show a loss when ROAS is above 1?
ROAS compares revenue with ad spend, but profit also depends on margin. If your gross margin is 40%, only 40% of revenue is available to cover ad costs, so you need ROAS above 2.5× before ads become profitable. The calculator subtracts ad spend from gross profit to show this.
Can I use this for Meta or Microsoft Ads?
Yes. The maths is the same for any pay-per-click platform. Enter the CPC, conversion rate and order value you see or expect on that platform. Costs and conversion rates often differ between platforms, so build a separate forecast for each one rather than averaging them together, and update it once real campaign data comes in.
