EPR Calculator
Understand your packaging data before reporting. Bring products, packaging layers, weights, assumptions and material totals into one clear company workspace.
Free web based tool • Company details required • CSV and PDF outputs
A practical starting point
Turn scattered packaging information into a usable product record.
Packaging information is often spread across spreadsheets, supplier emails, specifications and assumptions. EPR Calculator gives your business one place to record what you know, estimate what is missing and review the result product by product.
It is designed to help teams organise packaging data, identify gaps and prepare more confidently for internal review or EPR reporting processes.
Estimate missing packaging weights
Enter a known weight or use the closest available packaging reference when an exact figure is not yet available.
Review totals, confidence and gaps
See material totals, packaging levels, assumptions, warnings and confidence before exporting the data.
Product by product
Build a clear packaging record around every product.
Start with the information already available inside your business. Each product can hold the details needed to understand how much packaging is associated with the quantity placed on the market.
Product name, category and SKU or internal reference
Quantity placed on the market and product dimensions
Primary, secondary and tertiary packaging layers
Material, packaging format and weight for each layer
Known data and estimates
Use exact weights where available and transparent estimates where they are not.
A product may include a bottle, tray, pouch or carton, a box used to group products, and transit packaging such as pallets or protective wrap. EPR Calculator lets you record each layer separately.
Enter a known packaging weight directly
Match an unknown layer to a relevant reference item
See the estimation method and matched reference
Keep known values and estimated values clearly separated
The calculator makes assumptions visible so your team knows which information should be checked or improved later.
Reference library
Build a packaging library that reflects your own business.
Search and filter shared references, add your own examples and record average weights and dimensions for packaging formats used by your company.
Filter by material and packaging type
Add private reference items for your company
Hide shared items that are not relevant
Restore hidden references whenever needed
Dashboard view
See where packaging weight is coming from.
Review packaging by material, packaging level, product category, confidence and date added. Use the dashboard to identify the products and assumptions that deserve the most attention.

Confidence and assumptions
Understand how reliable each packaging estimate is.
EPR Calculator does not hide uncertainty. Each estimate can show the matched reference, the method used, whether a known weight was supplied and any warning caused by missing information.
High
Strong information or a close, relevant match supports the result.
Medium
The estimate is useful, but one or more inputs may need confirmation.
Low
Important information is missing or the available reference is not a close match.
Company workspace
Keep the team working from the same packaging data.
The first person who creates a company becomes the administrator. They can generate an invite code, add colleagues and manage company access. Team members work from the same products, reference items and reports rather than maintaining separate spreadsheet versions.

Getting started
From account creation to a usable packaging report.
01
Create or join a company
Choose Start a company and enter your name, company, email and password. When a workspace already exists, choose Join with a code and use the code supplied by the company administrator.
02
Confirm your email address
Open the confirmation email and verify the account before accessing the workspace. This keeps company access connected to a verified user.
03
Add the first product
Enter the product name, category, reference, quantity and dimensions, then add each applicable packaging layer.
04
Add weights or create estimates
Enter known packaging weights where available. For missing values, review the reference match, estimated weight and confidence before saving.
05
Review the product result
Check weight per unit, total packaging weight, material and packaging level breakdowns, confidence, assumptions and warnings.
06
Use the dashboard and reports
Identify material trends, high weight products and confidence gaps. Export the CSV or print the report as a PDF for internal review and further analysis.
Reporting and export
Move from product records to a detailed packaging report.
Reports bring together the number of products assessed, weight by material, weight by packaging type, layer level assumptions, warnings, missing data notes and average confidence.

A practical data tool, not an automatic regulatory submission service.
Results are estimates based on the information entered and the reference items available in the workspace. Review outputs against company records, supplier specifications and requirements that apply to your organisation before making a regulatory submission or commercial decision. EPR Calculator does not submit returns to a regulator on your behalf.
Common questions
What businesses need to know.
Is EPR Calculator free?
Yes. Businesses can create a free company workspace and begin adding products and packaging information.
Can the tool be used when packaging weights are missing?
Yes. A known weight can be entered directly, or the calculator can use available information and a suitable reference item to create an estimate.
Can several colleagues use the same data?
Yes. Company administrators can invite colleagues into the same workspace so the team can use shared product, packaging and report data.
Does the calculator submit an EPR return?
No. The tool supports data organisation, estimation, review and export. Your organisation remains responsible for checking requirements and completing any applicable submission process.
