Payroll needs decimal hours, people track time in hours and minutes — and converting between the two is where timesheet math goes wrong. 39 hours 15 minutes is 39.25 hours, not 39.15.

TCalc adds up your daily entries as real durations and converts the total to decimal with one tap. The HR layout below has one-tap keys for standard shifts, so a whole week takes seconds to enter.

Real Examples

8h 12m + 7h 48m + 8h 30m + 6h 45m + 8h=39.25h

A full week added up, shown in decimal hours for payroll.

17:30 - 09:00 - 30m=8h

One day's hours from clock-in, clock-out, and lunch.

7h 45m * 5=38.75h

Frequently Asked Questions

How do I add up timesheet hours?

Add each day's hours and minutes, letting minutes carry into hours: 8h 12m + 7h 48m + 8h 30m + 6h 45m + 8h = 39h 15m. TCalc computes the whole week in one expression.

How do I convert timesheet hours to decimal for payroll?

Divide minutes by 60: 39h 15m = 39.25 hours. In TCalc, switch the output format to hours and any total displays as decimal instantly — no manual conversion.

Can I calculate overtime with this?

Yes — subtract the standard week from the actual total: enter the weekly sum, then subtract 40h. What remains is the overtime. With PRO you can add a custom one-tap button for your standard week.
