About the timesheet calculator
A week of start times, end times and half-hour lunches is annoying to add up by hand, mostly because time is base sixty and money is base ten. This calculator does the conversion and gives you both the hours worked and the amount to bill.
Enter a start and end time for each day of the week and the number of minutes you took for breaks. The tool handles shifts that run past midnight, so a session from 21:30 to 02:00 counts as four and a half hours rather than producing a negative number. Days you did not work can be left blank.
Set an hourly rate and an optional weekly overtime threshold. Hours above the threshold are paid at your overtime multiplier — commonly 1.5 — and the summary separates regular pay from overtime pay so the split is visible to whoever approves the timesheet.
The daily breakdown shows hours in both decimal and hours-and-minutes form. Decimal is what invoicing and payroll systems expect; 7 hours 45 minutes is 7.75, not 7.45, and that specific mistake accounts for a surprising amount of underbilling.
Nothing is stored unless you are signed in, in which case the week is saved so you can reopen it. When the week is done, take the total straight into the invoice generator.
