I am trying to create a formula that will help me predict a future date based on an average time per day.
For example, I have a range of dates [1/12/2022, 5/12/2022, 15/12/2022], and each date has an amount of hours spent on that day [4, 2, 12]. At the moment I have a formula which will work out the average p/day by dividing the total by the start and current date.
What I want is to then predict the date based on this average hours (say 4 p/day) I will reach a goal of 2000.
An example sheet would look like this -
If below scenario is your input data then the following formula may help.
=C2+ROUNDUP(B2/A2,0)
I really couldn't put the title into words very well. I will link a template spreadsheet below.
I've been working on a formula for hours now however I keep hitting dead ends. I'm unable to effectively do what I believe should be feasible. I'd give my attempts however I believe it would be of zero help, instead I'll explain my desired outcome.
I have a page with my employees, the E column isn't populated right now as I'd like to create a formula (ARRAYFORMULA so I don't have to paste a formula into each cell) to calculate the output based on a few conditions and values.
Vacation days are calculated as follows. The CEO gets 5, managers get 3 and assistants get 1. Extra vacation days based on points employees receive, 30 points or above is 5, 20 points or above is 3 and 10 or above point is 1.
Calculating the amount of vacation days employees have earned wasn't the hard part for me, it was having the formula subtract days based on how many vacation days have been used in the past 30 days.
We log vacations on the vacation page. The formula on the employees page needs to calculate how many vacation days each employee has used in the past 30 days only and subtract that from the total earned vacation days that employee has earned.
I'd like for the formula to use TODAY() to calculate 30 days in the past however for the sake of this example I'll use the date 06/09/2021 instead for continuity.
Sorry if I haven't explained this well or I'm asking too much in one go, I figured all the context is required.
Example sheet
I'm trying to come up with a function that will calculate a monthly budget from within a specified date range. I tried to use SUMIFS but I can't figure out how to isolate a specific month within the range.
Example:
We have a sheet with Google Ad campaigns, with a row for each campaign.
We are running one Google Ad campaign (A) from 2/15/20 to 5/15/20 with a total budget of $3000 from which I calculate a daily budget of $33.33.
We are running a second campaign (B) from 5/15/20 to 8/15/20, also with a budget of $3,000, from which I calculate a daily budget of $32.61.
=IF(NOT(ISBLANK(Start_Date)),Total_Budget/(End_Date-Start_Date),"")
In a separate sheet, I have Budget and Spend fields for each month. For May, I need it to calculate the total budget for 5/1-5/15 of Campaign A, and 5/15-5/31 of Campaign B.
I got this far (J is the Daily_Budget, G is the Start_Date, and H is the End_Date):
=SUMIFS(Google!J2:J30, Google!G2:G30,"<="&DATE(2020,5,1),Google!H2:H30,">="&DATE(2020,5,31))
Then I was at a loss for how to extrapolate the number of days from the range, so that I could then multiply them by the Daily Budget and then add them together.
I thought of going back to the sheet that contains the campaigns and adding columns for each month with a complicated conditional, and then just using SUM(), but I feel like there has to be a more elegant solution.
UPDATE
Per request, here is a link to the spreadsheet with the desired results manually entered: Click here. May & June show the campaign partial month overlaps. The result I'm ultimately going for is =(15*Google!J2)+(16*Google!J3).
UPDATE 2 (24Jun20)
Per request, I have shared the spreadsheet so that people can make a copy and experiment with formulas: Click here..
Any ideas?
Thanks,

I would use the function DATEDIF() (documentation here). You can set the first parameter as the first day of the month you are trying to calculate the number of days within it, and the second as the first day from another month. Example:
DATEDIF(DATE(2020, 1, 1), DATE(2020, 2, 1), "D")
You could probably make a custom function with this as well to input only the number of each month (and year, in case of leap years on February), but I don't have much experience with that unfortunately.
I have a set of data (see image below)
What I would like to do is calculate the average total for each person per day for the whole date range.
I know that I can go through and tediously do it by calculating the sum for each person on each day and then at the very end get the average for each day on each person, but what I am trying to figure out is if there is a faster or more efficient way to do the same thing. Thank you for any help.
Let me excuse me for not finding the answer to my question. I've got no clue on what to look for.
I'm keeping a logbook with times. It contains information with how long I have worked. I need to make a graph that will show the amount of work I've done in total.
For example on day 1 I worked 1 hour and on day 2 I have worked 2 hours.
I fill the date in column A and the labour in column B. In my graph I need to see that I have worked 1 hour total on day 1, and I have worked 3 hours total on day 2 (basically I need to sum everything up)
I've tried fixing this myself by making a sum of the column in a new column, but this is just way too much work to do for the amount of rows I need.
I've did this for every cell in column E through row 14, until I decided to ask help from stack overflow
E1:
=SOM($D1:D1)
