In this lesson

  • A relative reference (F1) moves when you copy the formula.
  • An absolute reference ($F$1) stays on F1 wherever the formula lands.
  • F$1 locks only the row, $F1 only the column. $F$1 is always safe.

Cheat sheet

  • A relative reference (F1) moves when you copy the formula: one row down, one row further.
  • An absolute reference ($F$1) stays on F1 wherever the formula lands.
  • Press F4 (Windows) or Fn+F4 (Mac) while the cursor is on a reference to add the $ signs.
  • F$1 locks only the row, $F1 only the column. $F$1 is always safe.
  • The symptom to remember: a copied formula gives a different, often zero, result in every row.
  • Excel and Google Sheets work the same way here; only the Mac shortcut differs.
