In Excel: use =SUM(range), for example =SUM(A1:A10), or =SUMIF(range, criteria, sum_range) to add only the rows that match a condition.

Click the empty cell where the total should go.
Type =SUM( and drag to select the range, then close the bracket and press Enter.
For a quick total, select the range and press Alt+= (Windows) to AutoSum it.
To total conditionally, use =SUMIF(criteria_range, condition, sum_range).
What this does
SUM adds every number in the range you give it, ignoring blanks and text so you do not have to clean the column first. It is the most-used function in any spreadsheet because totals are everywhere. When you only want some of the values, SUMIF (one condition) and SUMIFS (several) add just the rows that meet your criteria. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “sum multiple cells in excel”. Start on a copy or a tiny sample, keep the affected cells visible, and compare the result with the outcome you expected before you touch the real workbook. 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. The point is a layout choice that keeps the sheet readable and sortable, but the practical win is that someone else can open the file and understand what happened without asking you.
A worked example
To total a column of sales in A1:A10, type =SUM(A1:A10). To total only the "North" region, =SUMIF(B1:B10,"North",A1:A10) adds the A-values whose B-cell says North. The AutoSum button (Alt+= on Windows) writes the SUM for you and guesses the range — handy, but always check the highlighted range is right. Every dashboard, invoice and budget ends in a total, which is why SUM — and its conditional cousins SUMIF and SUMIFS — is the first function worth mastering. Get it right and the rest of the sheet builds on solid ground. Check the referenced cells, argument order and result type in your workbook. Start with the worked example before changing an input, then compare the changed result with the calculation you expected. An error value or a result of a different type is a reason to inspect the inputs and arguments.
In Google Sheets
The standard worksheet functions used by this example are listed in Google Sheets. Check the cell references, argument separators and input types in the target spreadsheet, then compare the worked result. This formula-availability check does not establish identical menus, keyboard shortcuts or workbook features, and it is not a product execution test. Nothing on this page is behind a login or a download: the exact answer is at the top, and the detail below it is there for when you need it. That is the whole promise here — the answer first, and just enough context to make it stick. For “sum multiple cells in excel”, keep the input cells and the result visible while you check the formula in Excel. Follow the worked example and change one input at a time. The steps explain the workbook calculation; this page does not run a live calculator for that task.
Common mistakes
- Letting AutoSum guess a range that misses the top or bottom row — always check the outline.
- Summing a column that includes its own total cell, creating a circular reference.
- Expecting
SUMto add text numbers — values stored as text are skipped silently. - Using
SUMIFwhen you need several conditions; reach forSUMIFSinstead.
Frequently asked questions
SUM vs AutoSum?
AutoSum is just a button that writes a SUM formula for the range it guesses. The formula is identical; AutoSum only saves typing.
How do I sum with a condition?
Use SUMIF for one condition (=SUMIF(range, ">100")) or SUMIFS for several criteria across different columns.
Why does SUM ignore some cells?
SUM only adds numbers; cells holding text, including numbers stored as text, are skipped. Convert them with VALUE or by multiplying by 1.
