Track daily work hours and calculate weekly pay

Enter clock-in and clock-out times for each day of the week, with break deductions. The calculator totals regular hours, overtime hours (above your threshold), and computes total pay at your hourly rate.

Round to the nearest 15 minutes as most employers do — it simplifies payroll without significant accuracy loss.

Real-Life Guide to Using the Time Card Calculator

Weekly work hours timesheet. Use the examples and checks below to turn the number into a practical decision.

When this calculator is useful

Used by hourly employees, shift workers, or small business owners to add up daily clock-in/clock-out times across a week (or pay period) into a total for payroll, without manually adding each day's hours by hand.

For most people, the best way to use the Time Card Calculator is to try the real case first, then change one input at a time. That makes the trade-off visible. For example, with a loan calculator you can change tenure while keeping the same rate; with an investment calculator you can change return assumption while keeping the same monthly contribution; with a health, education or measurement calculator you can check how much one input changes the final category.

The result should answer a practical question: Can I afford this? How much should I save? Is this score enough? Is this measurement within range? What is the safer or cheaper option? If the output does not answer the decision clearly, adjust the inputs until the scenario matches your real situation.

Real-Life Example

Weekly payroll timesheet: A retail store employee in Chennai clocks in and out six days a week and needs a weekly total to submit to the store manager for payroll.

1Logging 9:00 AM–6:00 PM Monday to Friday (with 1-hour lunch each day, giving 8 hours net) plus 9:00 AM–2:00 PM Saturday (5 hours, no break) totals 45 hours for the week.

2Now change one input, such as rate, time, quantity, unit or score, and compare the new result with the first one.

Enter each day's break separately rather than one lump weekly deduction, since break lengths and workdays can vary day to day.

Practical Advice

Use the Time Card Calculator as a planning tool, not just a number generator. Write down the inputs you used, because the final answer is meaningful only when you remember the assumptions behind it.

If the decision affects money, health, tax, safety, academics or legal compliance, keep a second check ready. That second check may be a bank quote, payslip, official rule, prescription, site measurement, mark sheet or invoice.

Common Mistakes

Forgetting to enter a break/lunch deduction for each day, so an 8-hour scheduled shift with a 30-minute lunch gets counted as a full 8 hours instead of 7.5.
Entering AM/PM incorrectly for an evening shift, e.g. logging a 6:00 PM clock-in as 6:00 AM, which throws off that day's total by 12 hours.
Adding daily totals in decimal and minute form inconsistently — writing "7:30" as 7.30 hours instead of 7.5 hours, which compounds into a noticeably wrong weekly total.
Missing a day's entry entirely (like a half-day Saturday) and assuming the week total is complete without it.
Not accounting for overnight shifts within the weekly grid — a shift starting 11 PM Tuesday and ending 7 AM Wednesday needs to be logged as spanning two calendar rows correctly, not squeezed into one day.

How to Interpret Results

The weekly total reflects the sum of each day's net hours after breaks — compare it against your expected contracted hours (e.g. 48 hours for a 6-day week) to spot missing punches or overtime before submitting it for payroll.

A good interpretation looks at both the main result and the supporting values. If a page shows totals, ratios, categories, schedules or warnings, read those together instead of focusing only on the biggest number.

Time Card Calculator FAQs

Useful answers for interpreting the output, avoiding mistakes and using the result responsibly.

What does the Time Card Calculator produce as its final output?

It produces a total number of hours worked across all the days you enter clock-in and clock-out times for, typically over a weekly or bi-weekly pay period, after subtracting any breaks you log per day.

How do I handle a shift that runs past midnight in the timesheet?

Log the clock-out time as being on the next calendar day (or use the overnight toggle if available) so the hours between, say, 11 PM and 7 AM are correctly counted as 8 hours rather than showing a negative or zero value.

Does it automatically subtract lunch breaks?

Only if you enter a break duration for that day — the calculator doesn't assume a default lunch length since break policies vary widely between employers, so leaving it blank means the full clocked span is counted.

Why does my weekly total look different from what payroll calculated?

Small mismatches are usually caused by different rounding rules — some employers round each punch to the nearest 15-minute mark, while this calculator uses exact entered times, so check your company's specific rounding policy if the difference is more than a few minutes.

Can this calculate overtime automatically?

The calculator gives you the total hours worked, and you can compare that figure against your standard weekly hours (commonly 40 or 48 depending on your employment terms) to work out overtime manually, since overtime rules and multipliers vary by company policy and state labour rules.

What format should I use for entering times — 12-hour or 24-hour?

Either works as long as you're consistent and correctly mark AM/PM when using the 12-hour format, since an unmarked or wrong AM/PM entry is the most common cause of a shift showing an unexpectedly large or negative number of hours.

Is a half-day or partial-day entry supported?

Yes, just enter the actual clock-in and clock-out times for that shorter day (like 9:00 AM to 1:00 PM for a 4-hour half-day) and it will be added into the weekly total exactly like any other day.

How is this different from the Hours Calculator on this site?

The Hours Calculator computes one continuous span between a single start and end date-time, while this Time Card Calculator is built for adding up multiple separate daily entries into one combined weekly total, which better matches how a real timesheet is structured.

About Time Cards

A time card records daily punch-in/punch-out times to calculate total work hours. Enter your start and end time for each day, subtract breaks, and the calculator totals your weekly hours and computes pay including any overtime.

In India, the Factories Act sets 8 hours as the standard working day. Any work beyond 9 hours per day or 48 hours per week qualifies as overtime and must be paid at double the ordinary rate of wages (Section 59 of the Factories Act, 1948). Use the OT threshold and multiplier fields to match your employment terms.

Frequently Asked Questions

How do I calculate weekly pay from time card entries?

Add up all clock-in to clock-out durations for the week. Multiply total regular hours by hourly rate. For overtime (hours over 48/week or 9/day under Indian law), apply twice the hourly rate. If salary is monthly, convert to hourly: hourly rate = monthly salary ÷ (working days per month × daily hours).

How are overnight shifts handled on a time card?

For a shift from 10 PM to 6 AM, the calculator handles clock-out before clock-in by automatically adding 24 hours to the end time, giving the correct 8-hour duration. Split night shifts across two dates are typically recorded as one shift entry spanning midnight, not split into two partial shifts.

What is the minimum rest period between shifts under Indian labour law?

The Factories Act specifies a minimum of 10.5 hours between consecutive shifts. The new Labour Codes propose that workers cannot work more than 5 hours without a 30-minute break, and that 12-hour shifts must be followed by a minimum 12-hour rest. State shops and establishments acts may have additional requirements for non-factory workers.
