How it works
Turn Campaign Assumptions Into a Useful Decision
A budget should begin with a business outcome, not an arbitrary daily number. This model starts with the conversions you need and works backwards through conversion rate to estimate required clicks. Multiplying those clicks by CPC produces a platform-spend estimate. It is a planning baseline rather than a promise because auction prices, search demand, impression share, and conversion performance can change.
If you need 100 conversions per month, expect a 5% conversion rate, and pay about $2 per click, you need roughly 2,000 clicks. The estimated platform budget is $4,000 per month, or about $133 per day over 30 days. If the conversion rate falls to 4%, required spend rises to $5,000, showing why landing-page performance matters to budgeting.

Questions answered
Frequently Asked Questions
Clear definitions for advertisers, business owners, and agencies planning paid campaigns.
How do I calculate a PPC budget?+
Divide your conversion target by conversion rate to estimate required clicks, then multiply those clicks by average CPC. Add a testing buffer when the inputs come from benchmarks rather than account history.
Should I plan a daily or monthly PPC budget?+
Plan monthly first so spend aligns with business targets, seasonality, and cash flow. Then divide the monthly amount by active campaign days to create a practical daily starting budget.
What conversion rate should I use?+
Use the rate for the same traffic source, campaign type, device mix, and conversion action. Your own recent account data is usually more useful than a broad industry average.
Does this budget include agency fees?+
This calculator estimates advertising platform spend. Add agency, creative, tracking, and landing-page costs separately when approving the complete marketing budget.
Can I use this calculator for Google Ads and paid social?+
Yes, if the campaign is purchased on a CPC basis or you can estimate an effective CPC. The calculation works for Google Ads, Microsoft Ads, Meta, LinkedIn, and similar platforms.
