Date based sum in Excel / Google Docs spreadsheets

Question

I have a bunch of rows with a date and a dollar amount (expenses).

I want to produce a list of the days of the month and what the balance of the expenses is. So, for example the 5th entry in the list would be 8/5/2008 and the sum of all the expenses that occurred on or before 8/5/2008. Approximately this is =sumif(D4:D30-A5,">0",E4:E30) but of course that doesn't work (where the source data is dates in D4:D30 and the expenses are in E4:E30).

Notes

• source data can't be sorted for various reasons.
• must work in google spreadsheets, which is a fairly complete subset of excel's functions.

Answer 1

The code

=SUMIF(D$2:D$30,"<="&A5,E$2:E$30)

should work in both Excel and Google Spreadsheets.
