Eight microlearning boxes
Define the denominator before calculating a rate
Bounce rate, open rate, CTR and utilization all depend on a specific denominator. Write it down before comparing numbers.
Separate observed metrics from modeled assumptions
A known click count is observed; a future CTR, billing increment or PTO usage plan is an assumption.
Use delivered email where the metric requires it
Open and click rates are often more meaningful when calculated from delivered messages rather than all attempted sends.
Time rounding can change money
Billing and payroll increments can change total hours and revenue, so the selected rule should always be visible.
Time zones are rules, not fixed offsets
IANA zones can change UTC offset across the year because of daylight-saving or government rule changes.
Scenario analysis is more useful than one number
Changing CTR, CPM, WPM, accrual or workload helps show how sensitive the result is to assumptions.
Local processing improves privacy
The primary calculator logic runs in your browser and requires no email, phone number or account.
Exports make assumptions auditable
Saving the summary and detail table makes later review, comparison and reproducibility easier.
