Who is the lot calculator for?
Built for UK bullion dealers, pawnbrokers, refiners and serious collectors who routinely value bags or boxes of mixed scrap and coins. Add as many lines as you need; the total updates instantly as you type. Your lot is saved locally to your browser — closing the tab and coming back later keeps your list.
How the totals work
Each line is independent. For every row the calculator converts your weight to grams, multiplies by purity (parts per 1000), and multiplies by the live per-gram spot price in GBP. The lot total is the sum of all rows; the breakdown shows the pure metal you'd recover per element.
