DAU / MAU Ratio
IntermediateThe DAU/MAU ratio is daily active users divided by monthly active users, showing what share of a month's users are present on an average day.
The ratio reads as an average number of active days per month: 20 percent means the typical monthly user showed up on about six days out of thirty. Both sides must use the same definition of active, otherwise the ratio measures the gap between two definitions rather than habit. For products that are not meant to be used daily, such as a tax filing service or a travel booking site, a low ratio is the correct outcome rather than a symptom. Imported benchmarks do not transfer either: what counts as healthy depends on the product's natural usage frequency, the sector, and whether active means a plain visit or a meaningful action.
How it is calculated
DAU/MAU ratio = daily active users ÷ monthly active users
The numerator is the unique active users of a single day and the denominator the unique active users of the thirty-day window containing that day, both counted with the same qualifying action. The result is a share, usually shown as a percentage; it is not additive, and a monthly figure comes from averaging the daily ratios rather than dividing sums.
