Distribute Weekly Amount Monthly

[molopez]

Hello!

I have a set of columns for Start / Finish / Weekly Amount, and the goal is to distribute the weekly amount into each month.

I attached a sample sheet with what the results should be.

Thanks for your help.

One other note: It appears that you are associating each number with the Monday date for that week. I assume this is intended to be the start of the week. So an event that occurs on 9/1 will be counted in the week of 8/28. You are allocating numbers to months based on the week's start dates, so therefore that event on 9/1 will be counted as being in August. Hopefully that is what you really want. The only way to put these in the true calendar months is to have daily data.

Yes, I already had a distribution based on a calculated daily amount, but the data I was given was in a weekly basis. That's why I was wondering if there was a better way.

Anyways, your solution really works :D

Thank you so much!
