Lunch breaks and hours worked

The basic day formula

Hours worked = clock-out − clock-in − unpaid break. If you start at 9:00, leave at 17:30, and take 30 minutes for lunch, you worked 8 hours. The Hours Calculator accepts those inputs and can multiply by an hourly rate for a rough gross figure.

Paid versus unpaid breaks

Policies differ. Some short rest breaks are paid; meal breaks are often unpaid. Enter only the unpaid minutes in the break field. If your workplace pays through lunch, leave the break at zero.

Overnight shifts

When a shift crosses midnight, enter times the way the tool expects. If the interface is same-day only, split the shift into two segments and add them with the Time Calculator.

Rounding rules

Employers sometimes round punches to the nearest 5 or 15 minutes. MeretAI shows the arithmetic from the times you type. If your workplace rounds, apply that rule to the inputs first so the result matches payroll.

Checking a whole week

Summing five separate day calculations by hand invites mistakes. Prefer the Time Card Calculator for a week or two-week view, including overtime. Use the single-day hours tool when you only need one shift.

Worked example

9:00 AM to 5:30 PM with a 30-minute lunch is 8.0 hours. At $20 per hour that day is $160 gross before taxes. Change the lunch to 45 minutes and the same clock times become 7.75 hours and $155.

Keep a habit of matching the payslip labels: regular hours, overtime hours, and rate. The calculators explain the math; payroll systems apply policy. For multi-day spans without clock times, the Business Days Calculator counts working days instead of hours.

Checklist before you buy or rely on the number

Write down the raw inputs you used, including units. Re-run the calculator once with those exact figures. If a store pack size or a syllabus rule forces a round-up, round up rather than chasing a perfect match. Keep a note of the date you calculated so you can compare later when prices, labels, or grades change.

A note on units

Keep units consistent inside one calculation. Mixing feet with metres, or cups with grams without a density, is the usual source of bad results. When a label uses a different unit, convert once with the Unit Converter and then return to the specialty calculator.

Limits

These figures are planning aids. Confirm product labels, syllabus rules, employer policy, or veterinary advice when a decision depends on the number.
