This page covers two categories: paid advertising calculators and funnel and conversion calculators. The paid ads tools help you work out cost per click, cost per acquisition, and return on ad spend across Facebook, Google, TikTok, and Pinterest before you commit budget to a campaign. The break-even ROAS calculator in particular is worth running before scaling any ad account, since it tells you the minimum return you need just to cover spend.
The funnel and conversion calculators model what happens after the click — sales funnel conversion rates, upsell and order bump revenue, webinar conversion percentages, and checkout abandonment losses. Used together with the paid ads calculators on this page, you can map the full path from ad spend to final revenue and find where the biggest leaks or opportunities actually are.
Most marketers track ad spend closely but underestimate how much revenue leaks out after the click. A campaign with a strong cost per click can still lose money if the landing page converts poorly, the checkout has high abandonment, or the upsell sequence underperforms. Running the ad calculators alongside the funnel calculators on this page gives you a single, consistent view of cost in versus revenue out, rather than treating ad performance and funnel performance as two separate problems to solve independently.
For Facebook, Google, TikTok, and Pinterest specifically, platform-level metrics like cost per impression and cost per click vary widely by niche and audience size, so there's no universal "good" number. Instead, use these calculators to find your own break-even threshold first — the point where ad spend and revenue are equal — and then treat any number above that as genuine profit rather than comparing yourself to industry averages that may not reflect your specific funnel or offer.
A reasonable workflow is to start with the ROAS or break-even ROAS calculator to set your minimum acceptable return, then use the conversion rate and landing page calculators to identify where visitors are dropping off before they convert. If your ad metrics look healthy but revenue is still lagging, the leak is almost always somewhere in the funnel — checkout abandonment, a weak upsell offer, or a webinar with low attendance-to-purchase conversion are the most common culprits, and each has its own calculator on this page to quantify exactly how much it's costing you.
