Subway Nutrition CalculatorWhy we built a Subway meal nutrition calculator
Restaurant nutrition tables are useful, but custom orders often require adding several rows and adjusting portions manually. This project turns that repetitive arithmetic into an interactive meal builder while keeping every selected component visible.
The goal is not to label one order as good or bad. It is to help a visitor compare a 6-inch sandwich with a Footlong, see what a sauce or side contributes, and review calories, protein, carbohydrates, fat, sodium, fibre, and sugars together before ordering.
How the Subway calculator stays independent
Subway Nutrition Calculator is an independent informational project. It is not affiliated with, sponsored by, or endorsed by Subway. Brand and product names are used only to identify the menu items being compared.
The site links to official regional nutrition pages wherever possible and distinguishes published serving values from calculator assumptions. It does not accept restaurant orders, manage Subway accounts, issue refunds, or speak for the brand, its franchisees, or individual restaurants.
How regional Subway nutrition sources are handled
Country pages identify an official source, market, and data version for verification. The current selectable catalog is shared across regions and is not presented as a complete transcription of every local menu. Regional menus can change at different times, so a value from one country should never be assumed to apply in another.
The United Kingdom and Germany pages support per-serving and per-100g comparisons, while Australia and New Zealand also display kilojoules. These display choices help visitors read local source documents, but they do not convert the shared catalog into an official regional database.
How the custom Subway meal calculator shows its work
Every selectable item contains a serving weight and nutrition record. Quantity, Footlong size, and sauce-portion controls apply visible multipliers, and the calculator adds matching nutrient fields across the complete selection. The current items remain listed beside the result so a total can be reproduced.
The full arithmetic, rounding rules, Daily Value references, and known limitations are documented on the Subway nutrition methodology page. The calculator runs without an account, and a downloaded summary is created locally in the browser.
How to report a Subway nutrition correction
Send the page URL, item name, displayed value, expected value, and official source through the contact page. Reproducible corrections are prioritized over unsourced menu claims.
Include the market and source publication date because the same product name may use a different recipe elsewhere. Use the contact and corrections pagefor data issues, broken controls, accessibility problems, or privacy questions.
