Why I made it
In my reporting work, I kept turning to online calculators for marketing metrics. I got tired of the ads that fill those sites, so I built one without them. More is planned: resources and notes on keeping data reporting consistent, along with what I have learned along the way.
What this is
A small set of plain tools for working with marketing numbers: calculators that show their formula and say what to consider when a result is better or worse than you hoped. It is for people who read reports and build dashboards, not only for specialists.
Your data
- No ads, no analytics, no cookies, and nothing is saved.
- No outside scripts, fonts or images. The numbers you type are worked out in your browser and go nowhere.
- Each calculator page is built to work offline once it has loaded.
Where the facts come from
- The formulas are standard. The Looker Studio notes link to Google's own help pages.
- Platforms rename and redefine measures. The date at the bottom of a page is when it was last updated. If your platform's export disagrees with this site, the platform's own help pages are right and this site is out of date.
- The calculators and the questions to consider are general guidance. They do not include benchmarks, because what counts as good depends on the industry, the platform and the goal.
- Google, Meta, LinkedIn, TikTok and YouTube are named only to describe their reports. This site is not connected to any of them.
