Rounding Up to Nearest 100 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.

Two Primary Methods

=CEILING(value, 100)

Rounds up to the nearest multiple of 100

=ROUNDUP(value, -2)

Rounds up to hundreds place (-2 means hundreds)

Quick Examples

Method 1: CEILING Function (Recommended)

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.

Syntax

=CEILING(number, 100)

Rounds UP to the nearest multiple of 100

Step-by-Step Instructions

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

Examples

=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.

Method 2: ROUNDUP Function (Alternative)

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.

Syntax

=ROUNDUP(number, -2)

-2 means "round to the hundreds place"

Understanding the -2 Parameter

  • -1: Rounds to tens place (10, 20, 30...)
  • -2: Rounds to hundreds place (100, 200, 300...)
  • -3: Rounds to thousands place (1000, 2000, 3000...)

Examples

=ROUNDUP(123, -2)200

=ROUNDUP(199, -2)200

=ROUNDUP(450, -2)500

=ROUNDUP(899, -2)900

=ROUNDUP(1001, -2)1100

When to Use CEILING vs ROUNDUP

Use CEILING When:

  • Rounding to multiples (5, 10, 100, 1000)
  • You want the formula to be self-documenting
  • Working with pricing or inventory
  • The multiple is easy to state (100, not "hundreds place")

=CEILING(123, 100)

Clear and explicit

Use ROUNDUP When:

  • You're already using ROUND functions
  • Consistency with existing formulas matters
  • You need to round to decimal places too
  • You prefer thinking in "place values"

=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.

Real-World Use Cases

Budget Planning

Round budget estimates up to nearest hundred for safety margin

Actual cost: $2,347

=CEILING(2347, 100) → $2,400

Built-in buffer of $53

Resource Planning

Calculate materials needed, always rounding up for sufficient supply

Materials needed: 567 units

=CEILING(567, 100) → 600 units

Order in cases of 100

Financial Projections

Present revenue estimates in clean, rounded figures

Projected revenue: $8,934

=CEILING(8934, 100) → $9,000

Easy to communicate figure

Estimate Calculations

Provide conservative estimates by always rounding up

Project hours: 123

=CEILING(123, 100) → 200 hours

Conservative time estimate
