How Days Off Are Calculated
Flux calculates banked days off using this formula:
(Actual income − Goal income) ÷ Value per day = Days off
For example, if your goal is $3,000 for the period, you've earned $3,400, and your value per day is $200, you've banked 2 days off ($400 ÷ $200).

This is recalculated automatically every time you log a new entry, so your Time Off Bank always reflects your most current income. Days are counted per your chosen goal period and add to your running total — they don't reset unless you choose to use or clear them.
