Formula to calculate annual leave for longer shifts

nerdyplayer 

To create a formula in Excel that calculates the number of days of annual leave for employees with varying shift lengths (9-hour and 8-hour shifts), you can indeed break it down as you described.

 Let's consider your scenario:

• Week 1: Mon-Thurs 9h shifts, Fri 8h shift
• Week 2: Mon-Thurs 9h shifts, Fri off
• Over a two-week period, the total hours work out to 80 hours.

The key here is to calculate the number of shifts that would make up the given hours of annual leave, taking into account the two different shift lengths.

Here's a step-by-step approach to creating the formula:

1. Calculate the number of 9-hour shifts.
2. Calculate the remaining hours and convert them into 8-hour shifts if necessary.
3. Sum the number of shifts.

Formula:

Assume the annual leave hours are in cell A1. The following formula calculates the total number of shifts:

1. Calculate the number of 9-hour shifts: INT(A1 / 9)
2. Calculate the remaining hours after 9-hour shifts: MOD(A1, 9)
3. Calculate the number of 8-hour shifts from the remaining hours: IF(MOD(A1, 9) > 0, 1, 0)
4. Sum these together to get the total number of days.

Here's the combined formula:

=INT(A1 / 9) + IF(MOD(A1, 9) > 0, 1, 0)

This formula counts the number of 9-hour shifts and then checks if there are any remaining hours that could constitute an 8-hour shift.

Example:

If A1 contains 16 hours of annual leave:

• INT(16 / 9) gives 1 (1 full 9-hour shift).
• MOD(16, 9) gives 7 (remaining hours after one 9-hour shift).
• IF(7 > 0, 1, 0) gives 1 (since 7 hours can be considered as one 8-hour shift).

Thus, the formula =INT(16 / 9) + IF(MOD(16, 9) > 0, 1, 0) results in 1 + 1, which equals 2.

For a more detailed formula that takes into account partial hours correctly, you can use:

=INT(A1 / 9) + IF(AND(MOD(A1, 9) > 0, MOD(A1, 9) <= 8), 1, 0) + IF(MOD(A1, 9) > 8, MOD(A1, 9) - 8, 0)

This formula ensures that:

• It calculates the number of 9-hour shifts.
• It adds one 8-hour shift if there are remaining hours up to 8.
• It adjusts for any hours beyond the 8 hours from the remainder.

Weekly Calculation:

To convert hours into weeks considering your special weekly shifts:

= A1 / 40

This formula assumes a 40-hour work week.

By using these formulas, you can create a more precise calculation for annual leave in terms of days and weeks, adjusting for the specific shift patterns in your organization. The text and the steps was created with the help of AI.
