If you’re working with structured data in Excel and need to find the maximum value based on criteria, the DMAX() function is a powerful tool 📈. It lets you extract the highest number from a database column only when specific conditions are met — perfect for sales reports, inventory systems, and data dashboards. Whether you’re on Windows, macOS, or Ubuntu/Linux, this guide will show you exactly how to use the DMAX function in Excel with practical examples, syntax breakdowns, and keyboard shortcuts 💻.
🧠 What is the DMAX Function in Excel?
The DMAX function is part of Excel’s Database Functions family. It returns the maximum numeric value in a specified field (column) of a database (table) where certain criteria are met.
✅ DMAX Function Syntax
=DMAX(database, field, criteria)
| Argument | Description |
|---|---|
database | The range of cells that make up the database (including headers) |
field | The column from which to return the max value (can be column label or index) |
criteria | The range that contains the conditions you want to apply |
📌 Both the database and criteria ranges must include headers.
🎯 Real-World Example of DMAX
Let’s say you have a sales table like this:
| Region | Salesperson | Sales |
|---|---|---|
| North | Alice | 1200 |
| South | Bob | 950 |
| North | Charlie | 1500 |
| East | Dana | 800 |
And your criteria table:
| Region |
|---|
| North |
Formula:
=DMAX(A1:C5, "Sales", E1:E2)
✅ Output: 1500
Because it returns the highest Sales in the “North” region.
📌 Key Use Cases for DMAX
- 🛒 Inventory: Find highest stock levels in a category
- 📊 Sales: Get top-performing regions or reps based on filter
- 🧮 Finance: Retrieve max revenue or expense with conditions
- 📅 HR: Highest salary in a specific department
🔁 DMAX with Field Name vs. Index
You can use either the column name or column number:
=DMAX(A1:C5, "Sales", E1:E2)
=DMAX(A1:C5, 3, E1:E2)
Both return the same result if column 3 is “Sales”.
🧩 How to Create a Criteria Table
- Use the exact same headers from the database
- Place the conditions under those headers
- Use this small range as the
criteriainput in your formula
✅ You can add multiple conditions across rows or columns (AND/OR logic supported).

🐧 DMAX in Ubuntu/Linux (LibreOffice Calc)
LibreOffice supports DMAX with the same syntax, but you may need to use semicolons (;) depending on your locale:
=DMAX(A1:C5; "Sales"; E1:E2)
✅ Result: Works just like Excel. Just ensure proper formatting and headers.
⚠️ Common DMAX Errors & Fixes
| Problem | Solution |
|---|---|
#VALUE! error | Field not found – use correct column name/index |
| Returns 0 | Criteria not matching – double-check spelling/format |
| Inconsistent headers | Criteria table must match database header exactly |
| Criteria range missing header | Always include header in criteria range |
