Before you commit a media budget, it helps to see the whole funnel on one screen. This calculator turns a monthly ad budget, a cost-per-click, a conversion rate and an average order value into the numbers that actually decide a campaign: clicks, conversions, revenue, return on ad spend (ROAS) and cost-per-acquisition (CPA).

How to read the results
- ROAS is revenue divided by ad spend. A 4.0× ROAS means every $1 spent returns $4 in revenue.
- Break-even ROAS is set by your gross margin — at a 60% margin you break even at roughly 1.67×. Below that you lose money even if sales look healthy.
- CPA is what you pay to win one customer. Compare it to average order value and lifetime value, not to spend alone.
Treat the output as a planning estimate. Real campaigns move with platform, audience, creative and season — use this to pressure-test a plan and set targets, then measure against live data.
