In Excel for Windows, right-click the worksheet tab and choose Move or Copy. Select Create a copy, choose the destination and confirm OK. Rename the new tab and check that the original remains. On Mac use Option-drag; in Excel for the web use the tab menu's Duplicate command.

Open your own copy of the existing Monthly Budget template linked below. Rename its Budget tab January. Keep the default sample values and the How to use sheet; this exercise uses the Groceries row at row 3.
Copy January within this workbook using the command for your platform below. Confirm that January still exists, then rename the copied tab February. Merely dragging a tab without the copy modifier moves it.
Before editing, check B3=450 and C3=512 on both month tabs. Select D3 and check that the formula bar contains =B3-C3; the expected result is -62 on each tab.
Select only February before editing: the month tabs must not be grouped. Change February C3 to the number 400, leaving B3 and the D3 formula intact.
Compare the two tabs with the expected-results table. February D3 should be 50; January C3 should remain 512 and January D3 should remain -62. Keep both tabs while checking the results.
Copy January to February without changing January
Use the unchanged default Monthly Budget template in your own practice copy. Rename Budget to January, duplicate that worksheet and name the copy February. Change only February C3 from 512 to 400, then compare both month tabs below.
| Worksheet | B3: Budgeted | C3: Actual | D3: Formula | D3: Expected difference |
|---|---|---|---|---|
| January | 450 | 512 | =B3-C3 | -62 |
| February | 450 | 400 | =B3-C3 | 50 |
If columns are cut off, scroll the table sideways.
- Before the edit, January and February both have B3=450, C3=512 and D3=-62 with formula =B3-C3.
- After the edit, February C3 is 400 and D3 is 50. January C3 stays 512 and D3 stays -62.
- A negative Difference means over budget; a positive Difference means the amount of budget remaining on that row.
- The original January tab and the How to use tab remain. Select only February before changing an input.
- Use the fixed expected results for the default template to check your own saved practice copy.

Copy a worksheet for the next month
The sheet tab identifies a worksheet inside the open workbook. Copying that tab gives the next month its own worksheet instead of pasting a rectangle of values over the first month. A separate tab is not a separate workbook file: Save As is a different task. Use a personal copy of the sample budget rather than overwriting a working household budget. Start with the existing Budget sheet and keep its formulas while you copy it for the next month.
A January and February budget you can check
The existing Monthly Budget template places Groceries in row 3. Budgeted is B3=450, Actual is C3=512 and Difference is D3 with =B3-C3. That difference is -62, meaning actual spending exceeds the budget by 62. After copying January to February, change only February C3 to 400. Its difference is then 50, meaning spending is 50 below budget. January must still show 512 and -62. The numbers illustrate a worksheet-copy check, not actual household records. If both months change, stop and check whether you edited grouped worksheets or reused the original tab. If the difference does not update, inspect the formula and calculation setting rather than typing 50 over D3.
Platform commands and formula checks
Windows supports Ctrl-drag to copy a tab as an alternative to Move or Copy. Mac uses Option-drag; let go of the mouse before Option. Excel for the web provides Duplicate in the sheet-tab menu for the current workbook. This same-workbook exercise does not teach copying sheets between browser workbooks. Formulas with an explicit January! reference need separate review: a new tab alone does not prove that every dependency belongs to February. This template's D3 instead uses unqualified B3 and C3, so inspect those cells on the active month tab. Keep the How to use tab and save your practice copy after checking both months.
Common mistakes
- Moving January instead of copying it; confirm the original tab is still present before editing.
- Changing both month tabs because worksheets are grouped. Select only February before entering 400.
- Typing 400 into
B3or replacingD3with the number 50; this exercise changes Actual inC3only. - Using cell Copy/Paste Values as a substitute for duplicating the worksheet, which would discard formulas if pasted as values.
- Assuming references to other sheets or workbooks automatically become independent after a tab is copied.
Frequently asked questions
What is the shortcut to duplicate a sheet?
Windows uses Ctrl-drag on the worksheet tab; Mac uses Option-drag. On Mac release the mouse before Option. For the browser version use the tab menu's Duplicate command instead of assuming a desktop modifier works there.
Why did January change when I edited February?
First check that you are on the new February tab and that the month tabs are not grouped. Grouped worksheet edits affect the same cells on the other grouped sheets. Keep a backup and check the original before saving.
Should I enter a new formula in the copied D3 cell?
No. Copying the template worksheet should retain =B3-C3. Inspect it in the formula bar, then change only February C3 to 400. The expected result is 50; do not type the expected result over the formula.
Does this create a separate workbook?
No. January and February are separate worksheets in the same practice workbook. A copy of the entire file or a sheet transferred to another workbook is a different task.
