Time Card / Hours Worked Calculator

A time card calculator converts clock-in and clock-out times into total hours worked, automatically subtracting unpaid breaks and splitting the result into regular, overtime, and double-time hours based on the thresholds you configure.

Subtract your clock-in time from your clock-out time to get total elapsed time, then subtract any unpaid break time. 9:00 AM to 5:00 PM is 8 hours elapsed; subtract a 1-hour unpaid lunch break to get 7 hours worked.

Calculate total elapsed time from clock-in to clock-out, then subtract the length of the unpaid break. 9:00 AM to 5:00 PM with a 1-hour unpaid break equals 8 hours elapsed minus 1 hour break, which is 7 hours worked.

When clock-out is earlier than clock-in (for example, 10:00 PM to 6:00 AM), the calculator assumes the shift crosses midnight and adds 24 hours to the clock-out time before subtracting, giving an accurate 8-hour result instead of a negative number.

Overtime is any time worked beyond a configured threshold. With a 40-hour weekly threshold, working 46 hours means 40 regular hours and 6 overtime hours. You can configure the threshold, multiplier, and whether overtime is calculated daily, weekly, or both.

Multiply overtime hours by your hourly rate and by your overtime multiplier. 3 overtime hours at $20 per hour with a 1.5× multiplier equals 3 × $20 × 1.5 = $90 in overtime pay.

8 hours is 8.0 in decimal time. A value like 8 hours 30 minutes converts to 8.5 decimal hours, since 30 minutes is half of 60 minutes.

Divide the number of minutes by 60. 45 minutes ÷ 60 = 0.75 decimal hours, and 90 minutes ÷ 60 = 1.5 decimal hours.

Yes. Switch to Weekly Time Card mode to enter clock-in, clock-out, and break times for Monday through Sunday, with weekly totals and regular/overtime/double-time breakdowns.

Yes. Enter your hourly rate and choose a display currency to see estimated regular pay, overtime pay, double-time pay, and total estimated pay alongside your calculated hours.

No. All calculations run entirely in your browser and are never sent to our server. Only your time-format preference is optionally remembered locally in your browser.

No. Overtime rules vary by country, state or province, industry, and individual employment contract. This calculator does not assume any specific jurisdiction's law — it applies the threshold and multiplier settings you enter.
