Turn a completion rate into days.
How the Habit Streak Completion Calculator works
Habit Streak Completion Calculator turns planned days and completion percent into days completed. It computes that as planned days times the completion percentage.
Worked example: with Planned days 30, Completion percent 86.67, this tool returns days completed 26.001 days, days missed 3.999 days. That default state is deterministic, so you can check the page against a known result before trusting your own numbers.
