How to Calculate Packaging Weight by Part Number using Excel Formulas
Question details
The user needs a dynamic formula to calculate the total packaging weight for various part numbers based on packaging types and the required quantities of lids, pallets, and collars.

- Device & OS
- not provided
- Scenario
- Managing logistics, shipping, or inventory data where component weights differ depending on the packaging type assigned to specific part numbers.
- Observed behavior
- Requires a solution to cross-reference the correct component weights for a given packaging type and multiply them by the required component quantities to yield the total weight.
Ensure your spreadsheet is organized with two clear sections: a data table tracking the part numbers and component quantities, and a separate reference matrix that lists the exact weight of each component (lids, pallets, collars) per packaging type.
Use MMULT, INDEX, and XMATCH to Calculate Total Weight
This advanced array formula looks up the packaging type associated with the part number and multiplies the required quantities by their corresponding component weights in one efficient step.
Combining MMULT with INDEX and XMATCH creates a powerful matrix multiplication formula. It avoids the need to write long, repetitive addition formulas for every single component.
Click on the cell where you want the total calculated weight for the first part number to appear (for example, cell J3).
Type the formula: =MMULT(E3:H3,INDEX($B$12:$E$15,0,XMATCH(B3,$B$11:$E$11))). Adjust E3:H3 to match your component quantities, $B$12:$E$15 to match your weight reference matrix, and $B$11:$E$11 to match your packaging type headers.
Press Enter to calculate the total weight for the first item.
Click the small square at the bottom-right corner of cell J3 and drag it down to automatically calculate the packaging weights for the remaining part numbers.

Frequently Asked Questions
Why is my MMULT formula returning a #VALUE! error?
The #VALUE! error in MMULT typically occurs when the number of columns in the first array does not match the number of rows in the second array. Double-check your data ranges to ensure the quantity array (e.g., E3:H3, which is 4 columns) aligns perfectly with the weight array (e.g., a 4-row matrix returned by INDEX).
Can I use XLOOKUP or VLOOKUP instead of INDEX and XMATCH?
Yes, if your reference table is formatted differently, you can use XLOOKUP or VLOOKUP to find the weight of each individual component, multiply it by the quantity, and add them together (e.g., =Qty1*VLOOKUP(...) + Qty2*VLOOKUP(...)). However, the MMULT method is much cleaner and more efficient for multiple components.
Are XMATCH and MMULT fully supported in WPS Spreadsheet?
Yes, WPS Spreadsheet supports both XMATCH and MMULT, ensuring complete compatibility with modern array formulas used for complex data analysis in Microsoft Excel.
