Amazon Wholesale Order Quantity Calculator
How many units to order: your share of the sales, rounded to whole cases, checked against the supplier’s minimum order and your budget.

-
Estimates only. Your share assumes the Buy Box rotates evenly between you and the other sellers; it is lower when Amazon sells the product or when others undercut the price.
How the calculator works
- Your share. The listing’s monthly sales divided by the sellers, including you. With 300 sales and 4 other sellers, expect about 60 a month.
- Cover the lead time. Your share times the months until a reorder can arrive, plus safety stock for slow deliveries and sales spikes.
- Whole cases. Rounded up to the supplier’s case pack.
- The minimum order. If the MOQ is higher, you have to buy the MOQ. Up to about three months of sales is usually acceptable for a product with a good ROI; more than that ties up your cash and risks dead stock.
- Your cap. If the order costs more than you want in one product, the calculator shows what your budget allows.
