Monday hours (h)Enter paid or scheduled hours before the shared unpaid-break deduction.Tuesday hours (h)Use decimal hours such as 7.5 for 7 hours 30 minutes.Wednesday hours (h)Keep daily hours visible so the weekly total can be checked.Thursday hours (h)Enter zero for a day not worked.Friday hours (h)The default week is five 8-hour days.Saturday hours (h)Optional weekend hours are included in the weekly total.Sunday hours (h)Optional Sunday hours are included in the weekly total.Total unpaid breaks (min/week)Enter total unpaid break minutes for the week, such as five 30-minute lunches = 150.Overtime threshold (h/week)Use the threshold required by the workplace or jurisdiction; 40 is a common simple example.Hourly rate ($/h)Optional gross-pay estimate before tax, deductions, allowances or payroll compliance checks.Overtime multiplier (×)Use 1.5 for time-and-a-half or change it to match the applicable rule.Hour rounding increment (h)Use 0.01 for payroll-prep notes or 0.25 for quarter-hour records.

Live result37.5 paid hoursDaily hours total 40 h · unpaid breaks 150 min = 2.5 h · paid hours 37.5 h · regular 37.5 h / overtime 0 h after 40 h threshold · gross estimate 937.50 at 25.00/h and 1.5× overtime · rounded to 0.01 h

Formula used

Raw weekly hours = Monday + Tuesday + Wednesday + Thursday + Friday + Saturday + Sunday. Paid hours = max(0, raw weekly hours − unpaid break minutes ÷ 60). Regular hours = min(paid hours, overtime threshold). Overtime hours = max(0, paid hours − overtime threshold). Gross pay = regular hours × hourly rate + overtime hours × hourly rate × overtime multiplier.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Visual grid

This result is a slice of the working week

Hours and minutes are micro-time. Mapping them onto a week shows how a simple total becomes part of payroll, breaks, overtime thresholds and workday rules.

A sterile total becomes clearer when it is placed on the weekly grid: workdays, rest days, breaks and thresholds all become visible.

Inputs

Monday hours: 8 h
Tuesday hours: 8 h
Wednesday hours: 8 h
Thursday hours: 8 h
Friday hours: 8 h
Saturday hours: 0 h
Sunday hours: 0 h
Total unpaid breaks: 150 min/week
Overtime threshold: 40 h/week
Hourly rate: 25 $/h
Overtime multiplier: 1.5 ×
Hour rounding increment: 0.01 h

Method

For five 8-hour days, raw weekly hours are 40.00. Subtract 150 unpaid break minutes ÷ 60 = 2.50 hours, leaving 37.50 paid hours. With a 40-hour threshold, regular hours are 37.50, overtime hours are 0.00 and gross pay at $25/hour is $937.50.

Assumptions

Daily entries are decimal hours, so 7.5 means 7 hours 30 minutes.
The unpaid break field is the total unpaid break minutes for the whole week, not per day.
The overtime threshold and multiplier are user-entered planning assumptions; payroll law, awards, contracts and workplace rules vary by jurisdiction.
Gross pay is shown before tax, social contributions, superannuation, allowances, deductions, rounding policies, holiday rules, weekend penalties or final payroll approval.

Notes

Use this space on the printed report for client, supplier, classroom, job-location, measurement, quote or approval notes.

Formula

Worked example

For five 8-hour days, raw weekly hours are 40.00. Subtract 150 unpaid break minutes ÷ 60 = 2.50 hours, leaving 37.50 paid hours. With a 40-hour threshold, regular hours are 37.50, overtime hours are 0.00 and gross pay at $25/hour is $937.50.

Professional note

Master’s Tip: print the time-card record before payroll review and write the worker, week start date and approval notes in the notes area. A total without the daily hours and break deduction is much harder to audit later.

Regional and unit assumptions

Standard or basis: decimal-hour weekly time-card arithmetic with a user-entered overtime threshold and multiplier. The calculator is a transparent planning record, not a jurisdiction-specific wage-law engine.

Assumptions and limitations

Daily entries are decimal hours, so 7.5 means 7 hours 30 minutes.
The unpaid break field is the total unpaid break minutes for the whole week, not per day.
The overtime threshold and multiplier are user-entered planning assumptions; payroll law, awards, contracts and workplace rules vary by jurisdiction.
Gross pay is shown before tax, social contributions, superannuation, allowances, deductions, rounding policies, holiday rules, weekend penalties or final payroll approval.
For official wage, tax, legal or compliance decisions, check the employer record and the relevant labour authority or payroll professional.

Methodology & Accuracy

How this calculator is checked

CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.

Formula used

Standard or basis

Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.

Questions

How do I calculate time card hours?

Add the daily hours for the week, subtract unpaid break minutes divided by 60, then split the paid hours into regular and overtime hours using the chosen threshold.

What does 7.5 hours mean on a time card?

7.5 hours means 7 hours and 30 minutes. Decimal hours are useful for payroll totals because minutes can be converted by dividing by 60.

Do unpaid breaks count as paid time?

This calculator subtracts the unpaid break minutes you enter. Whether a break is paid or unpaid depends on the workplace rule, contract and jurisdiction.

Can this calculate overtime pay?

Yes, for a simple entered threshold and multiplier. It estimates regular hours, overtime hours and gross pay, but it does not replace official payroll rules.

What should a printed time card report include?

Print the daily hours, unpaid break total, overtime threshold, hourly rate, multiplier, regular hours, overtime hours, gross estimate, formula, assumptions, page URL, date and approval notes.

Calculation note

Time cards turn a week of lived work into an auditable payroll record. The arithmetic is simple, but the trust comes from showing the daily entries, break deduction, threshold and gross-pay assumption beside the answer.

The daily row is the evidence

A weekly total is easier to dispute than a row-by-row card. Keeping Monday through Sunday visible helps workers, supervisors and payroll staff find missing shifts, accidental zeros or break mistakes.

Decimal hours make payroll arithmetic easier

Minutes become decimal hours by dividing by 60. That is why 30 minutes becomes 0.5 hours and 15 minutes becomes 0.25 hours on many payroll worksheets.

Printable records protect context

A filed time-card report should show the worker, week, daily hours, unpaid breaks, threshold and approval notes. Without that context, a gross-pay number can look more official than it is.
