Food cost calculators and tools
Seven tools, all reading the same database of published menu prices. Rank every market by what your order costs, read an exchange rate out of a burger, estimate a group bill, budget a trip, or filter a menu by what the chain actually published about allergens.
None of these tools ask you to type in a price. They run on 1,852 prices that chains published on their own menus, converted through mid-market rates that are refreshed every Monday. That is the whole design: a calculator is only as honest as the numbers underneath it, and a food-cost estimate built on guesses is a guess with extra steps.
Where the data runs out, the tools say so rather than filling the gap. The nutrition builder offers 19 of 35 chains because the rest publish nothing verifiable. The allergen finder shows items with no published information as their own group, labelled unknown. A market missing one item from your basket is excluded from the ranking instead of being quietly totalled anyway.
Compare markets
Four ways to ask what the same food costs somewhere else.
Compare two markets
Match one chain's shared products across two countries, convert to US dollars and see the largest gaps as a chart.
Compare menus → ComparatorCheapest Market Finder
Build an order from one chain and rank every market that sells all of it by what the basket costs. Markets missing an item are listed, not silently dropped.
Rank markets → EconomicsPurchasing Power Calculator
The Big Mac Index method applied to any of 333 products: the exchange rate a menu price implies, next to the real one.
Run a currency → ComparatorGlobal Basket Comparator
Select identical products and price the basket in two countries, locally and in US dollars, item by item.
Build a basket →Plan and budget
Turn menu averages into a figure you can actually plan against.
What is in the food
Both of these are gated on the source. Where a chain published nothing, they show nothing rather than estimating.
Nutrition Builder
Add per-serving values from 174 profiles transcribed from official brand publications, across 19 chains.
Build a meal → Source-gatedAllergen & Dietary Finder
Filter a menu by what the chain published. Contains and may-contain stay separate, and items with no published data are shown as unknown, never as safe.

Live figures from the current data, each linking to the run that produced it.
How the numbers work
Prices. Every figure starts life on a chain's own menu or published price list for that market. Nothing is estimated, averaged across countries, or carried over from a similar product. Where a market publishes no price, the tools exclude it rather than guessing at one.
Currency. Local prices convert through mid-market rates refreshed every Monday, last on 22 August 2026, covering 20 currencies. Mid-market is not the rate a card issuer gives you, so treat a converted figure as a comparison, not a quote. The stored dollar figures are recomputed at every refresh, so a rate change moves what you see here rather than sitting in a table nobody reads.
Nutrition and allergens. Both come from the chain's own publications, per serving, transcribed as printed and never converted from per-100g figures. Most chains publish neither in any machine- readable form, which is why coverage is partial and why the tools name the gap instead of hiding it.
What these results are not. Reference estimates, not quotes. Outlet pricing, delivery mark-ups, taxes, promotions, portion sizes and local recipes all move the real bill. Read the methodology for how each of these is sourced and checked.
