The top-up is calculated using an average valuation of £1.68/kg for all food donated by you. This valuation is calculated by looking up the items that make up a standard food parcel (as handed out by the charity) and checking the prices of these items in Tesco’s standard own-label range. The total weight of the box and total value of all the items inside are then used to reach the £1.68/kg valuation used. On the day of the collections, stores with Trussell Trust foodbanks will weigh all the food collected, calculate a total value (at £1.68/kg), of which 30% will be given by Tesco to the Trussell Trust (11105222). In stores that are collecting for FareShare, the food will be delivered back to FareShare’s local depots, where the food will be weighed. The total weight collected will be used to calculate a total value (based on the £1.68/kg valuation), of which 30% will be given by Tesco to FareShare (1100051).
The meals total is based on an initial estimated weight of food collected, as we will not have the final weights until several weeks after the collection. From the December collection we know that the average weight of a green tray of food is 10.2kg. We have recorded the total number of trays of food collected from 30 Extra, 30 Superstores, 30 Metros and 50 Express stores across the country. From this we have calculated the average number of trays collected in each of the formats. Dependent on the number of different format stores across the region we have used this to calculate a regional total. We have then multiplied this by 10.2 kilos to get the total weight. The charities have provided us with a figure of 420g = 1 meal. We use this to calculate the meals total across the region.
For example if 30 Metros have collected 3,000 trays, the average per store will be 100 trays of food. If there are then 50 Metros across London the total collected across Metros will be 5,000 trays. Therefore 5000 x 10.2 kg = 51,000kg, which is the equivalent of 121,429 meals.
