Put your stock questions
into numbers.

Three straightforward calculators. Use your own numbers, see the formulas, and understand the assumptions.

Choose a calculator based on the decision in front of you: when to reorder, how long your stock may last, or how a selling price affects gross profit. Have your recent sales, available quantities, supplier delivery times, and unit costs ready. Keep units consistent, especially when buying cartons and selling individual items. Use the result as a starting point, then allow for seasonal demand, delayed deliveries, and the other costs of running your shop.
