Hours Calculator

Find total hours from start and end times, then see the same time as decimal hours and optional estimated pay.

Enter your work punches

Weekly totals

Replace the sample punches with your own. Blank days count as zero.

Use 9:00am, 17:00 or 1700. Breaks are unpaid minutes; leave zero for a break already punched out.

Times such as 915, 9.15am, 9:15 PM, and 21:15 work. A shift ending earlier than it starts is treated as overnight. Shifts belong to the day they start.

How to use this calculator

  1. Enter your starting and finishing times for each day.
  2. Subtract any unpaid break that is not already a gap between punches.
  3. Type your hourly rate to view pay and compare the decimal-hour total with your payroll record.

Formula

Total hours = net worked minutes ÷ 60. At a single regular rate, straight-time pay = decimal hours × hourly rate. When the chosen rule allocates overtime, apply its multiplier only to the relevant hours.

Worked examples

Eight hours plus forty-five minutes

Schedule: 8:45 of net worked time. The engine calculates 8:45 (8.75 hours).

Regular: 8:45 (8.75 h); overtime: 0:00 (0.00 h); double time: 0:00 (0.00 h). At $24.00 per hour, estimated gross pay is $210.00.

Hours calculator with pay

A time total and a pay total answer different questions. First establish the amount of work actually recorded; then attach the correct hourly rate and overtime setting. Leaving the rate blank still gives a useful hours calculation. Entering a rate reveals the gross estimate before any deductions. If your week uses more than one rate, this single-rate model cannot reproduce a blended payroll calculation, so retain the time totals and review the pay calculation separately.

Decimal output without losing minutes

An hour contains sixty minutes, while a decimal place represents a fraction of one. Forty-five minutes therefore becomes 0.75 hours, not 0.45. The card keeps integer minutes during calculation and rounds the displayed decimal result to two places. When comparing a long card with a spreadsheet, use the original minutes rather than adding many individually rounded decimal entries; small display differences can otherwise accumulate.

Check hours before money

When a total is unexpected, temporarily leave the rate out of the comparison and reconcile the hours first. Check a single shift from its start through its finish, then compare the weekly sum. This separates a clock-entry mistake from a pay-allocation question. For a short test, enter one known interval and leave the other rows empty. Once that duration agrees with your source, add the remaining days and restore the rate for the earnings estimate.

Overnight shifts and workday attribution

Each punch segment belongs entirely to the day it starts. An out time earlier than the in time crosses midnight. Daily totals, daily overtime, California seventh-day overtime, and weekly overtime all use that start-day attribution, including across a biweekly boundary. California daily overtime counts all hours attributed to that 24-hour workday. Employers may define a different fixed 24-hour workday, such as one starting at 6:00 a.m., so payroll results can differ.

Frequently asked questions

Can I calculate hours without a pay rate?

Yes. Leave the optional rate field empty. Worked time, regular hours, and overtime allocations remain available. Add a rate later if you need a gross-pay estimate from the same punches.

Does this include an hours calculator decimal view?

Each day and the summary display decimal hours next to H:MM. The decimal form is intended for numeric hour fields, while H:MM is easier to compare with a clock or handwritten timesheet.

What should I check if the pay looks wrong?

Check AM/PM, unpaid break deductions, the week boundary, rate, and selected rule. A break recorded both as a punch gap and as deduction minutes will remove the same time twice.

How are overnight shifts counted?

A 10pm–6am segment counts as eight hours on its start day. A 6pm–8am segment counts as fourteen hours there, giving eight regular, four overtime, and two double-time hours under standard California rules. It stays in the starting workweek. An employer’s different fixed 24-hour workday, such as 6:00 a.m. to 6:00 a.m., can change the result.
