Step by step
- 1B:B is the column to total; A:A holds the dates.
- 2The first condition keeps rows on or after the 1st of the month.
- 3The second keeps rows before the 1st of the next month — together that is exactly one month.
Tips
- Use EOMONTH to build the bounds dynamically from a single date cell.
- A helper column =TEXT(A2, "yyyy-mm") plus SUMIF is an easy alternative for grouping by month.

Frequently asked
Why not use MONTH() inside SUMIFS?
SUMIFS criteria can’t call MONTH() on the range. Use date bounds (>= start, < next month), or add a helper column with the month and SUMIF on that.
