In Excel: put a $ before the column letter and/or the row number to lock that part when the formula is copied — =$A$1 locks both, and the fastest way to add them is to press F4 while editing the reference.
Click into the cell and start editing the formula.
Select the reference you want to anchor (e.g. F1).
Press F4 to insert the dollar signs — once for $F$1, again for F$1, again for $F1.
Press Enter, then fill the formula down or across; the anchored part stays fixed.
What this does
A dollar sign anchors part of a cell reference so it does not shift when you copy or fill the formula. =$A$1 is fully absolute (both column and row are locked). =A$1 and =$A1 are mixed references that lock only one part — the row in =A$1, the column in =$A1. =A1 with no dollar signs is relative and adjusts freely. Pressing F4 while a reference is selected in the formula bar cycles it A1 → $A$1 → A$1 → $A1 → A1, so you rarely type the dollar signs by hand. Keep the inputs visible and clearly labelled and the whole thing stays auditable — anyone who opens the file later, including you, can see at a glance exactly what feeds the result and change one assumption without hunting through the formula. Treat “what is a mixed cell reference in excel” as a small repeatable workflow rather than a one-off click you hope to remember next time. Use a small test block before the live file, so any surprise in the affected cells shows up while it is still harmless. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. That turns a layout choice that keeps the sheet readable and sortable into a method you can reuse, explain, and defend when the workbook leaves your screen.
A worked example
=B2*$F$1 multiplies each row's value in column B by the single tax rate stored in F1. When you fill it down, B2 becomes B3, B4 and so on, but $F$1 stays put — every row keeps pointing at the one rate cell instead of drifting to F2, F3. Anchoring references is what lets one tested formula fill across hundreds of rows without the rates, totals or lookup tables it depends on sliding out of place. One habit worth forming early: name the cells that hold your inputs, so the formula reads in plain language instead of a string of cell addresses. A reviewer — or you in three months — can then follow the logic without decoding what B7 and D2 were supposed to mean, which is most of what makes a sheet maintainable.
In Google Sheets
If you are in Google Sheets rather than Excel, the good news is that the formula shown here is identical and the workflow barely changes — menus sit across the top instead of in a ribbon, and a few function names differ slightly, but anything you build here moves across with little or no rework. Keep this page bookmarked for the next time the same question comes up. Better still, rebuild the example once in your own sheet — doing it yourself, with the tool above to check against, is what turns a copied formula into a technique you own. Treat “what is a mixed cell reference in excel” as a small building block rather than a chore. Once the inputs sit in their own cells and the formula reads from them, the same setup answers a dozen related questions with a tweak, and Excel keeps every dependent figure current as the data changes. The tool above is there so you can rehearse and verify before committing anything to a real workbook; the steps and worked example are there so the logic sticks. Get it right once and it stops costing you time — it starts saving it, every time the question comes back around.
Common mistakes
- Leaving a lookup table, rate or assumption relative, so it drifts off-target when you fill down.
- Locking both parts (
$A$1) when you only needed to lock the column or the row. - Typing the dollar signs in the wrong place — $ goes before the part you want to freeze, not after.
- Forgetting that on a Mac you may need fn+
F4or Cmd+T depending on the keyboard.
Frequently asked questions
What does the dollar sign do in an Excel formula?
It locks the column ($A1), the row (A$1), or both ($A$1) so that part does not change when the formula is copied.
What is the shortcut for an absolute reference?
Select the reference while editing and press F4. On a Mac use F4, fn+F4, or Cmd+T depending on your keyboard.
What is the difference between absolute and mixed references?
Absolute ($A$1) locks both column and row; mixed locks only one — $A1 keeps the column, A$1 keeps the row.
