Learn how to always round UP to the nearest hundred in Excel
When you need to always round UP to the nearest hundred, Excel provides two excellent functions: CEILING and ROUNDUP. Both ensure that any value is rounded upward to the next multiple of 100.
=CEILING(value, 100)
Rounds up to the nearest multiple of 100
=ROUNDUP(value, -2)
Rounds up to hundreds place (-2 means hundreds)
| Original | Rounded Up to 100 |
|---|---|
| 123 | 200 |
| 450 | 500 |
| 899 | 900 |
| 1001 | 1100 |
The CEILING function is the most intuitive way to round up to the nearest 100. It rounds a number up to the nearest multiple of the significance you specify.
=CEILING(number, 100)
Rounds UP to the nearest multiple of 100
Step 1: Click the cell where you want the result
Step 2: Type =CEILING(
Step 3: Click the cell with your number or type it directly
Step 4: Type , 100) and press Enter
Step 5: The result will be rounded UP to the nearest 100
=CEILING(123, 100) → 200
=CEILING(199, 100) → 200
=CEILING(450, 100) → 500
=CEILING(899, 100) → 900
=CEILING(1001, 100) → 1100
=CEILING(2567, 100) → 2600
Why CEILING is recommended: It's easy to understand and explicitly shows you're rounding to a multiple of 100. The formula is self-documenting.
The ROUNDUP function can also round up to the nearest 100 by using -2 as the num_digits parameter. The negative number indicates which place to round to.
=ROUNDUP(number, -2)
-2 means "round to the hundreds place"
=ROUNDUP(123, -2) → 200
=ROUNDUP(199, -2) → 200
=ROUNDUP(450, -2) → 500
=ROUNDUP(899, -2) → 900
=ROUNDUP(1001, -2) → 1100
=CEILING(123, 100)
Clear and explicit
=ROUNDUP(123, -2)
Consistent with ROUND family
Bottom line: Both methods produce identical results. Choose based on your preference and what makes your formulas easier to understand.
| Original Value | CEILING Result | ROUNDUP Result |
|---|---|---|
| 50 | 100 | 100 |
| 101 | 200 | 200 |
| 250 | 300 | 300 |
| 567 | 600 | 600 |
| 999 | 1000 | 1000 |
| 1234 | 1300 | 1300 |
| 5678 | 5700 | 5700 |
