Egg mayo sandwich: how much it costs to make, per serve
Two hard-boiled eggs mashed with mayonnaise, black pepper and a few salad leaves on thick white bread. One sandwich, costed from JJ Foodservice prices dated 10 October 2026.
The main price uses 68% GP, in line with the UK food GP benchmarks (UKHospitality × Christie & Co, 2022: 65.9–69% food GP across every segment). The 75% line is a premium price; few UK sites hold it across a whole menu. GP is worked out on the ex-VAT price.
VAT: cold food such as a sandwich or wrap sold to take away is zero-rated; eaten on your premises (including your own tables outside) it is standard-rated at 20%, and so is anything you heat before selling it. HMRC VAT Notice 709/1, section 4.1: “Cold takeaway food and drink is zero-rated, as long as it’s not of a type that’s always standard-rated” (Catering, takeaway food).

Cost per line is pack price × (amount used ÷ pack size), the same sum the tool runs. Change one pack price and every line that uses it moves.
Method
- Boil the eggs for 9-10 minutes, cool in cold water and peel.
- Mash with the mayonnaise, salt and pepper.
- Spread on one slice, add the leaves, top with the second slice and cut.
Costing notes
The ingredients come to £0.57. A thick-sliced 800 g loaf gives about 18 slices of roughly 44 g, so two slices are 88 g. The packaging is not in this costing: a sandwich wedge or bag is a real cost for takeaway, so add a row for it in the tool.
VAT changes the price on the board here. A cold sandwich sold to take away is zero-rated; the same sandwich eaten at your tables is standard-rated at 20%. So the same 68% GP needs £1.78 to take away and £2.13 to eat in.
Where the prices came from
JJ Foodservice collection prices as shown on its public search pages on 10 October 2026 (delivery runs about £1-2 a case higher; one line JJ listed on delivery only is marked). JJ does not label VAT on most lines: raw food is zero-rated in the UK, while soft drinks, alcohol, confectionery and some ingredients carry standard-rate VAT. Your supplier's price is the one that matters: open the recipe and type it in.
