The Number formats guide
A number format changes how a value looks, not the value. Select the cells, then use the Home tab or a shortcut: Ctrl+Shift+$ for currency, Ctrl+Shift+% for percent, Ctrl+B for bold.
Format, don't retype
Typing "$8.50" or "12.5%" into a cell works in Excel, but it's slower than formatting a whole column at once and easy to get wrong. Select the range, then pick the format: the numbers underneath stay the same, so totals and formulas keep working.
The shortcuts
- Ctrl+B: bold (press again to turn it off).
- Ctrl+Shift+$: currency with two decimals.
- Ctrl+Shift+%: percent with no decimals. Then Increase Decimal on the Home tab for one decimal.
- Ctrl+1: the Format Cells dialog, for everything else.
On a Mac, use ⌘ for Ctrl in the first and last; the currency and percent shortcuts use ⌃⇧.
Percent: 0.125 is 12.5%
The percent format multiplies by 100 for display. A growth of 0.125 shows as 12.5%. If the cell already holds 12.5, the percent format shows 1250%: the value should have been divided by 100, not formatted. Formats never fix the value itself.
Common mistakes
- Formatting the header with the numbers. Select from row 2 for number formats; the header gets bold only.
- Pressing bold twice. The shortcut switches bold on and off.
- Rounding by format. Fewer decimals on screen doesn't change the stored number. To change the value, use ROUND.
FAQ
- What is the shortcut for currency format in Excel?
- Ctrl+Shift+$ on Windows applies the currency format with two decimals. On a Mac it is Control+Shift+$.
- How do I show a percent with one decimal in Excel?
- Apply the percent format (Ctrl+Shift+%), then click Increase Decimal once on the Home tab, or set one decimal place in Format Cells (Ctrl+1).
- Does a number format change the value?
- No. It changes what the cell shows. Formulas still use the full stored value; to change the value, use ROUND.
- Why does my percent show 1250%?
- The cell holds 12.5, not 0.125. The percent format multiplies by 100 to display. Divide the value by 100, or type it as 12.5%.
