This calculator only adds time into decimal hours — the basis of every pay sheet. But overtime rules (double rate, weekly caps, separate holiday rates) differ by employer.
Once you have total decimal hours, use the overtime calculator for the money side with rules applied. To derive the hourly rate from a monthly salary, see the salary calculator.
Frequently asked questions
How many decimal hours is 45 minutes?
45 ÷ 60 = 0.75 hours. 15 minutes = 0.25, 30 minutes = 0.50 — see the full chart below.
What if I enter 60 or more minutes?
Not allowed — minutes must be a whole number from 0 to 59. Write 75 minutes as 1 hour 15 minutes.
How is overtime pay calculated?
Decimal hours × hourly rate. For example, 26 × ৳192.31 = ৳5,000.06. For rule-based pay (double rate, weekly limits), see the overtime calculator.
What shows when the rate is 0?
Only total time and decimal hours; the pay line is hidden.
How does the minute carry work?
Add the minutes and divide by 60: the quotient joins the hours, the remainder stays as minutes. For example, 45 + 30 = 75 = 1 hour 15 minutes.
How do I get the hourly rate from a monthly salary?
Divide the monthly salary by the month's total working hours. Use the salary calculator for salary breakdowns.
