Understanding your inputs
Each input field is labeled with the specific value it expects. Hover over the ? hint icons (where present) for additional guidance on what each field means and what units to use. For best results, double-check that all your input values use consistent units before calculating.
Interpreting the results
Results are shown immediately after clicking Calculate. The highlighted result card shows the primary output — the value most people need.

Frequently Asked Questions
How often should I recalculate these metrics?
Track key metrics weekly for rapidly-changing inputs (ad spend, conversion rates) and monthly for slower-moving metrics (subscriber growth, revenue trends). Daily tracking creates noise that obscures real trends — focus on week-over-week or month-over-month comparisons for most business metrics.
What's a good benchmark for this metric?
Benchmarks vary significantly by industry, company size, and channel. Instead of comparing to industry averages (which are often meaningless), track your own trend over time and focus on consistent improvement. Compare yourself to your own historical baseline first; industry benchmarks are a secondary reference.
How does sample size affect these calculations?
Small samples produce unreliable metrics with wide confidence intervals. For A/B tests, you typically need at least 100–200 conversions per variant for reliable results. For engagement metrics, look for statistical stability by tracking how much the metric fluctuates week to week — high variance signals insufficient data.
Should I use mean or median for this analysis?
Use the median when your data has outliers or is skewed (which is common for revenue, session duration, and time-based metrics). Use the mean when data is approximately normally distributed and you want a metric influenced by all values. For most digital marketing metrics, median gives you a more representative picture of typical performance.
