  1. 1. Start 09:00 = 540 minutes after midnight; end 17:30 = 1050 minutes after midnight.
  2. 2. Same-day gross = 1050 − 540 = 510 minutes.
  3. 3. Net = 510 − 30 = 480 minutes = 8 decimal hours.

Break time is deducted once from the gross clock interval. No automatic paid-break, rounding or overtime rule is inferred.

Pay is a simple gross arithmetic estimate using the entered hourly rate; taxes, overtime rules, premiums and deductions are outside this owner.

How to use this calculator

Shift Hours Calculator works with time durations. Enter the times shown by the tool and read the elapsed result in the units displayed; overnight handling is stated beside the result when it applies.

Step-by-step

  1. Step 1

    Enter the start/base time.

  2. Step 2

    Enter the end time, duration or break requested by this calculator.

  3. Step 3

    Review the elapsed result and any day rollover shown.

Common questions

Can the calculation cross midnight?

Where the tool says overnight rollover is supported, an earlier end clock time is treated as the following day.

Are decimal hours available?

Work-duration tools show decimal hours where that representation is useful.

Are time zones included?

Ordinary clock-time inputs do not contain time-zone information. Use a Time Zone Calculator when zones matter.

Planning notes

Shift length and simple pay are different layers

The calculator first derives net worked time after an unpaid break. If a rate is entered, it multiplies net decimal hours by that rate as a simple estimate.

Example: 8 net hours at 20 per hour

8.0 × 20 = 160 estimated pay before any overtime, premiums, tax or deductions.

Useful for

  • Single-shift time and pay checks
  • Casual/freelance shift estimates
  • Comparing shift schedules

Limits and assumptions

  • The pay result is arithmetic, not a payroll statement.
  • Overtime, premiums, taxes and deductions are outside this owner.
  • Currency is intentionally not inferred from locale.

Questions about this planning model

Does this calculate overtime?

No. Use the Overtime or payroll calculators when an overtime threshold and multiplier are needed.

Can hourly rate be zero?

Yes. The shift duration remains useful without a pay estimate.

Can break time exceed the shift?

No. That impossible state is rejected.
