Holiday calculator need help - time sensitive

[colinheslop1984]

I'm creating a holiday tracker that has certain requirements and I'm stuck. I feel like the solution is something simple but I'm giving up and asking for help.

I'll do my best to explain...

Holidays are accrued at the rates you see in right most side of the table based on length of service.

Holiday is calculated as follows:

Accrual rate x contracted hours = annual hours

If starting part way through year then calculated as:

Annual hours / 52 x weeks left in year

So Joe for example:

would accrue 5.6 x 40 =224 hours , 224 / 52 x 48 = allowance

As length of service increases, so does Accrual as seen on the right of the table below.

For example Peter
Would accrue 36 week at rate of 6, but 16 weeks at 5.8
So 6x30 / 52 x 36 + 5.8x30 / 52 x 16

I need a formula to calculate this in the annual allowance column, the ones I've tried are not accurately calculating

Then I also want to calculate accrued to date, using current week in top left corner as a criteria

Can any one put me out of my misery and help

Hi Colin,

Is this what you need? Note that the accrued to date sumifs adds annual allowance for the staff name, this name should be the full name to keep the sum criteria unique;

Book1

1	Current week ->	37			52
2		Contracted hours	start week	length of service	annual allowance	accrued to date			Accrual rate	length of service
3	Joe	40	4	0	159.47	159.47			5.6	0
4	Peter	30	16	2	128.02	128.02			5.8	1
