Work time made clearer
Work time calculations without the guesswork
Calculate hours worked, build a weekly time card, find your clock-out time, or estimate overtime pay. Hourformula gives you clear results without requiring an account.

From clock times to decimal hours
Work-time questions often use several formats at once. A shift might start and end as clock times, its duration may be easier to read as hours and minutes, and the same duration may need to become decimal hours before arithmetic such as multiplication or averaging.
Hourformula keeps those steps separate. Duration tools answer how much time elapsed. Conversion tools change the representation of that duration. Time-card and work-hours tools can also account for unpaid breaks. Overtime tools then apply the threshold, rate, and multiplier you enter to an already calculated total.

Calculators, guides, conversions, and charts
Use calculators when you need an answer from your own inputs. Use guides when you want to understand the rule. Conversion pages are useful for exact minute/hour values, while charts are designed for quick lookup when you do not need an interactive form.
Clear calculations, sensible limits
Hourformula shows the arithmetic behind your result. Results are general-purpose estimates—not legal, tax, or payroll advice. When an external policy, contract, holiday calendar, or employment rule controls the real outcome, verify that rule separately.
