Enter the total hours worked, break time, and lunch time into the calculator to determine the deducted time.

Deduct Time Formula

The following formula is used to calculate the deducted time.

DT = TH - (B + L)


  • DT is the deducted time (hours)
  • TH is the total hours worked (hours)
  • B is the break time (hours)
  • L is the lunch time (hours)

To calculate the deducted time, subtract the sum of break time and lunch time from the total hours worked. This will give the actual hours an employee has spent working, excluding their rest periods.

What is Deduct Time?

Deduct time refers to the amount of time subtracted from an employee’s total hours worked, typically for breaks or lunch periods. This is often used in payroll calculations to ensure that employees are only paid for the actual time they spent working, not for their rest periods. The specifics of when and how much time to deduct can vary depending on company policy and labor laws.

How to Calculate Deduct Time?

The following steps outline how to calculate the Deduct Time (DT) using the formula: DT = TH – (B + L).

  1. First, determine the total hours worked (TH) in hours.
  2. Next, determine the break time (B) in hours.
  3. Next, determine the lunch time (L) in hours.
  4. Next, substitute the values of TH, B, and L into the formula DT = TH – (B + L).
  5. Finally, calculate the Deduct Time (DT).
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Total hours worked (TH) = 40 hours

Break time (B) = 2 hours

Lunch time (L) = 1 hour
