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 July collection we know that the average weight of a green tray of food is 11.1kg. From the estimated total of full trays given to us by each store across the UK we have then calculated the total weight using the 11.1 average. This has then given us a total weight for each store. The charities have provided us with a figure of 420g = 1 meal. We use this to calculate the meals total across the UK.
So for example if the total estimated weight collected in one store equals 700kg (divided by 0.42 the average weight of a meal) = 1,667 meals. This would then be top up by our 30% so would equal 2,167 meals.
