Step by step
- 1COUNTA(A1:A7) finds the last filled row by counting non-empty cells.
- 2OFFSET starts that many rows down minus N, then takes a block N rows tall and 1 column wide.
- 3SUM totals that final block — here the last 3 values, 40 + 50 + 60 = 150.
Tips
- Change the two 3s to sum a different number of trailing rows.
- Widen A1:A7 to your real column (e.g. A1:A1000) so the formula keeps working as data grows.

Frequently asked
How do I sum the last N rows ignoring blanks in between?
COUNTA counts only non-empty cells, so gaps are skipped when locating the end, but the N-row block itself is positional. For scattered data, filter first.
