Introduction to MROUND in Excel
Rounding numbers doesn’t have to be a chore. 🎯 With the MROUND function in Excel, you can easily round any number to the nearest multiple — like 5, 10, 0.25, or even 0.01. Whether you’re working with currency, time intervals, or product quantities, MROUND keeps your data tidy and your calculations consistent.
Let’s explore what MROUND does, how to use it properly, and how it compares to other Excel rounding tools.
What Is the MROUND Function?
The MROUND function in Excel returns a number rounded to the nearest multiple you specify. It’s a great alternative to generic rounding when you need more control.
Example:
=MROUND(17, 5)
👉 Returns 15 because 15 is the nearest multiple of 5 to 17.
Syntax of the MROUND Function
=MROUND(number, multiple)
- number: The value you want to round.
- multiple: The multiple to which you want to round.
🧠 Both arguments must have the same sign (positive or negative), or Excel will return an error.
Practical Examples of MROUND
| Formula | Result | Explanation |
|---|---|---|
=MROUND(28, 10) | 30 | Rounds 28 to nearest 10 |
=MROUND(14.7, 0.5) | 14.5 | Rounds to nearest half |
=MROUND(-17, -4) | -16 | Rounds -17 to nearest multiple of -4 |
=MROUND(2.75, 0.2) | 2.8 | Rounds up to nearest multiple of 0.2 |
💡 It’s perfect for scenarios like pricing, inventory units, and time slots.
Rounding Positive and Negative Numbers
MROUND handles negative values — but both the number and the multiple must share the same sign.
Correct:
=MROUND(-15, -4) → -16
Incorrect (throws error):
=MROUND(-15, 4) → #NUM!
✅ Always keep the sign consistent.
Rounding to the Nearest 5, 10, 0.1, etc.
Common use cases:
- Round to the nearest 5 cents:
=MROUND(1.37, 0.05)→ 1.35 - Round to the nearest 10 units:
=MROUND(94, 10)→ 90 - Round to the nearest half hour:
=MROUND(1.4, 0.5)→ 1.5
This flexibility makes it superior to regular ROUND() for structured data rounding.
Difference Between MROUND, ROUND, and CEILING
| Function | Behavior | Example (18.3, 5) |
|---|---|---|
MROUND | Rounds to nearest multiple | 20 |
ROUND | Rounds to decimal places | Depends on digits |
CEILING | Rounds up to nearest multiple | 20 |
FLOOR | Rounds down to nearest multiple | 15 |
🧭 Use MROUND for flexible, midpoint rounding.
MROUND for Time and Currency Calculations
- ⏰ Round hours to the nearest 15-minute interval:
=MROUND(2.34, 0.25) - 💰 Round cash prices:
=MROUND(9.37, 0.05) - 📦 Round inventory packages:
=MROUND(47, 6)
It’s a go-to for accurate business rounding.
Common Errors with MROUND
| Error | Cause | Fix |
|---|---|---|
#NUM! | Different signs in number & multiple | Make both positive or negative |
| Incorrect output | Floating point precision issues | Use rounding adjustments |
✅ Tip: Round intermediate values separately if needed.
MROUND Across Columns and Rows
Apply MROUND to ranges:
=MROUND(A2:A10, 0.1)
For older Excel versions, use array formulas or fill handle to apply it down columns.
Combine MROUND with IF Statements
You can round conditionally:
=IF(A2>50, MROUND(A2, 10), A2)
👉 Only round if the value is over 50. Otherwise, return as is.
Using MROUND for Inventory, Finance, and Sales
- 🧾 Finance: Round billing amounts to nearest $0.05
- 🏪 Inventory: Package items in multiples (e.g., 6, 12, 24)
- 📈 Sales: Adjust prices or quantities for reports
💼 Great for business logic and reporting clarity.
Formatting MROUND Results
Use number formatting:
- Add decimal precision:
=TEXT(MROUND(A1, 0.05), "$0.00") - Keep consistent units across columns
- Highlight rounded cells with conditional formatting 🎨
MROUND and Decimal Precision
For financial models or engineering, precise decimals matter. MROUND helps:
=MROUND(A2, 0.01) → rounds to cents
=MROUND(A2, 0.0001) → scientific use
🧪 Combine with ROUND() for total control.

When MROUND Doesn’t Work (Fixes)
- Ensure both inputs are numbers (not text)
- Match signs of number and multiple
- Avoid nested rounding that interferes
- Use
ROUND(MROUND(...), n)to control decimals
⚠️ Stay aware of floating point issues when working with very small multiples.
MROUND and Math Functions Like ABS or INT
You can build smart formulas:
=ABS(MROUND(A2, 0.5))
Or combine with INT():
=INT(MROUND(A2, 1)) → Rounds to nearest integer multiple

FAQs About MROUND in Excel
What is MROUND in Excel used for?
To round numbers to the nearest specified multiple.
Does MROUND round up or down?
It rounds to the nearest — up or down, depending on which is closer.
Why am I getting #NUM! in my MROUND formula?
Your number and multiple have opposite signs. Make both positive or both negative.
