Timesheet Calculator Online – Track Work Hours & Pay

What Does This Calculator Do?

Keeping track of work hours accurately — especially across multiple days, with breaks, overtime, and varying pay rates — is something that trips up employees and small business owners alike. A rough mental tally at the end of the week almost never adds up correctly, and spreadsheets take time to set up. This Timesheet Calculator gives you a proper, structured way to log your work hours for any number of days, automatically calculate your regular and overtime hours, and figure out exactly what your pay should be — all in one place.

You can add as many work entries as you need, one for each shift or working day. For each entry, you log the date, your start time, your end time, and any break duration in minutes. The calculator subtracts the break time automatically so you’re only counting actual working time. Once all your entries are in, it totals everything up and splits the result into regular hours and overtime hours based on the threshold you define — giving you a clear, honest picture of both your time and your earnings.

The results are displayed in a clean visual summary card at the top, followed by a detailed breakdown table that shows every individual work entry with its regular hours, overtime hours, and total hours side by side. This makes it easy to spot any discrepancies, verify your entries, or share the breakdown with a manager or payroll processor.

How It Calculates Overtime

The calculator gives you two overtime methods to choose from, reflecting the two most common ways employers calculate overtime:

Daily Threshold Method: Overtime is calculated per individual workday. Any hours worked beyond the daily threshold on a given day count as overtime for that day, regardless of the total hours worked during the rest of the week. For example, if your daily threshold is 8 hours and you worked 10 hours on Monday, 2 of those hours are overtime — even if you only worked 5 hours on Tuesday.

Formula per day: Regular Hours = Min(Hours Worked, Daily Threshold) | Overtime Hours = Max(0, Hours Worked − Daily Threshold)

Weekly Threshold Method: Overtime is calculated based on the total cumulative hours across all entries for the week. Hours are counted as regular until the weekly threshold is reached, and everything beyond that point is overtime. For example, if your weekly threshold is 40 hours and your total across all entries is 47 hours, then 40 hours are regular and 7 hours are overtime.

Formula: Regular Hours = Min(Total Hours Worked, Weekly Threshold) | Overtime Hours = Max(0, Total Hours Worked − Weekly Threshold)

Pay Calculation:

Once regular and overtime hours are determined, the pay is calculated as:

Total Pay = (Regular Hours × Regular Rate) + (Overtime Hours × Overtime Rate)

For example, if you have 40 regular hours at $20/hr and 7 overtime hours at $30/hr: (40 × 20) + (7 × 30) = $800 + $210 = $1,010 total pay.

If you leave the pay rate fields at zero, the calculator simply gives you the hour totals without a pay calculation — useful if you just need to track time rather than earnings.

How to Use It

Building your timesheet takes just a minute or two:

1. Fill in your first Work Entry — select the date, start time (hour, minute, AM/PM), end time, and enter any break duration in minutes
2. Click Add Another Entry to add more work days and repeat for each shift
3. Use Remove Entry to delete any entry you added by mistake
4. Choose your Overtime Method — Daily Threshold or Weekly Threshold
5. Enter your Threshold in hours (e.g., 8 for daily or 40 for weekly)
6. Optionally enter your Regular Rate and Overtime Rate in dollars per hour if you want a pay calculation
7. Click Calculate Timesheet to see your results
8. Review the total hours summary card and the full per-entry breakdown table below
9. Click Reset to clear everything and start a fresh timesheet

Why It’s Worth Using

Payroll errors cost both employees and employers. Workers end up underpaid when overtime isn’t calculated correctly, and employers face compliance issues when records don’t match actual hours. This calculator removes the guesswork by applying the correct formula for whichever overtime method your workplace uses, automatically deducting break time, and presenting a clear itemized breakdown that you can refer to or share.

It’s just as useful for freelancers and self-employed people who bill clients by the hour and need a clean, accurate record of time worked across multiple sessions or days. You get the total hours, the pay calculation, and a full entry-by-entry breakdown — everything you’d need to put together an accurate invoice or timesheet to submit.
