NPM Multiple Product Calculator
The Multiple Product Calculator mode enables you to upload information for multiple products and run the entire table through the Nutrient Profile Model. Note that this calculator is not optimized for mobile use and is recommended for use at a computer. Please use the Single Product Calculator for on-the-go mobile scoring.
How to use the Multiple Product Calculator:
1. Download the template Excel or CSV file provided.2. Prepare your data, ensuring you are using the correct column names and categories (the template Excel file contains drop down options for categorical variables).
3. Select the ‘Upload Data’ tab.
4. Upload your Excel or CSV file – once uploaded you can preview to check the data looks correct.
5. Click ‘Calculate NPM scores’
6. The calculator will provide a summary and small preview of the results. Any errors will be flagged at this stage.
7. Download your full results (CSV file).
Help using the tool
Our tools are designed to be intuitive and easy to use. Please read our detailed user guide for step-by-step instructions.
Should you experience any difficulties using the NPM Calculator, please contact info@cdrc.ac.uk including a screenshot of any relevant error messages.
Results
See below for the NPM calculator results on your dataset. You can also download this updated dataframe via the Download button.
If one of your data entries returns ERROR instead of an NPM assessment and score (PASS or FAIL), please check that all required parameters have been filled in. Ensure 'fvn_measurement_percent' is set to a value at/between 0 and 100.
The Multiple Product Calculator uses the nutrientprofiler R package to calculate NPM scores. Find out more about this package here: nutrient profiler documentation . This tool currently uses nutrientprofiler version 2.0.0. Please note this alongside your analysis.

Input Parameters
Visit the NPM guidance for full details.
What is the NPM?
The UK Nutrient Profile Model assesses the 'healthiness' of products by assigning a score based on nutritional information.
The NPM score underpins:
-
Product advertising (on TV, online, on the Transport For London network and more)
-
Product promotions in stores and online shopping platforms
How is the NPM score calculated?
Points are assigned to components, according to their amounts per 100g of product. Points are grouped into A-points and B-points.
A-points
These are the 'less healthy' components which the model discourages
C-points
These are the 'healthier' components which the model encourages.
Scoring
The scores for C-points are then deducted from the scores for A-points, to give the overall score.
If a product scores 11 or more for A-points then it cannot score points for protein, unless it also scores 5 points for fruit, vegetables and nuts.
For drinks, if a product scores 1 or higher, the product is classed as 'less healthy' and is said to FAIL the NPM.
For foods, if a product scores 4 or higher, the product is classed as 'less healthy' and is said to FAIL the NPM.
Products which fail the NPM may be subject to certain restrictions on advertising and promotions, depending on the type of product and the specifics of the legislation.
Visit the NPM guidance for full details.
What is HFSS legislation?
HFSS stands for 'High in Fat, Sugar or Salt'. This tool is designed to support implementation and enforcement of The Food (Promotion and Placement) (England) Regulations 2021 , which we dub 'HFSS legislation'. From October 2022, new legislation will limit the placement of HFSS products in stores, removing them from prime locations like store entrances, the ends of aisles, and at the checkouts. Guidance for the legislation is available online.
Under the guidance , a product is considered HFSS if it falls into one of the 13 categories listed in the table below, or if it fails the UK NPM. The NPM Calculator will let you know the HFSS status of foods you enter.
Please note that restrictions on promotions only apply to packaged products sold in eligible retailers. This tool is not designed to assess retailer eligibility.
Make sure you're up to date with the rules .
HFSS categories in The Food (Promotion and Placement) (England) Regulations 2021
Specific gravity
Nutrient values for drinks, and some foods, are typically presented per 100ml of product. But the NPM applies per 100g of product.
A specific gravity conversion factor can be applied to convert the volume in ml to weight in grams. This accounts for the density of the prodcut.
While pure water has a specific gravity of 1, meaning that 1ml or pure water weighs 1g, most drinks will have a higher density.
For ease for the user, this calculator uses pre-set specific gravity conversion factors, which will be applied according to the type of product you select.
Specific gravity values are listed in the table below.
Specific gravity values
Specific gravity values are taken from The 2018 review of the UK Nutrient Profiling Model Appendix A , pages 95-96. For products not listed, a specific gravity of 1 is applied
The Nutrient Profile Model online calculator tool is developed and maintained by the Consumer Data Research Centre, University of Leeds.

Development
The NPM Calculator is based on the MSc work of Vicki Jenneson. The original code for that project can be found on GitHub , and was previously tested on a retail product dataset from Dietary Assessment Ltd.
Current code for the NPM Calculator can be found on the CDRC GitHub page.
Under the hood, the Multiple Product Calculator uses the nutrientprofiler R package to calculate NPM scores. Find out more about this package here: nutrient profiler documentation . This tool currently uses nutrientprofiler version 2.0.0. Please note this alongside your analysis.
