# Excel/Formula to calculate and round time worked.

Question
Richard,

I need help with a formula for my employees timesheeet / timeclock spreadsheet. I'd like to enter start time in B1, end time in C1, and have total hours worked rounded to the quarter hour in D1. Also, if possible I'd like to add 20 minutes of paid lunch to any hours totaling 7.5 or more.

Example 1: (B1)8:30am (C1)4:30pm (D1) would = 8 plus 20 min lunch then rounding to quarter hour would make answer 8.25

Example 2: (B1)8:30am (C1)2:39pm (D1)6.25 (6 hours 9 minutes worked would round to 6.25 and since under 7.5 hours no paid lunch added.

THANKS!

See this tutorial on CALCULATING THE DIFFERENCE BETWEEN TWO TIMES.

Then you could use an IF FUNCTION to add on 20 minutes if you want.
