SUM IF FORMULA BASED ON CURRENT/PREVIOUS/NEXT Month

[AK123]

Dear All

I have attached a spreadsheet I am currently working on. I have a list of dates and a list of revenue. I would like to use a SUMIF formula to total up the revenue for specific months, however it goes slightly further then this. I have listed the month buckets I require in A2:D7.

B2 - I need the sum of all revenues that are prior to todays month (i.e before march), please note that I want to use the today function so that the formula can be future proof i.e in April it will automatically total all fees prior to april, without me having to edit the formula.
D2 - will show the sum of all revenues in March (todays month) I have already tried using the formula: =SUMIF(D9:D1000,">="&DATE(YEAR(TODAY()),MONTH(TODAY()),1),E9:E1000)-SUMIF(D9:D1000,">"&DATE(YEAR(TODAY()),MONTH(TODAY())+1,1),E9:E1000)
however this sum of 2,576 does not reconcile with the sum i get of 2,270 when adding manually.
D3 - will show the sum of all revenues in the NEXT (April) month i.e todays month +1 month
D4 - will show the sum of all revenues in the SECOND NEXT (May) month i.e todays month +2 month

The rest of the buckets are self explanatory, sum of all fees between june and august in D5. D6 will show the sum of all revenues in august onwards.

If you could populate the table and re-attach that will be a great help.

Please let me know if you have any other questions.

Thanks,
AK
