Why is cost per unit important for pricing?

Knowing your cost per unit ensures you set prices above your break-even point. It also helps compare supplier quotes and identify economies of scale as production volumes increase.

Does cost per unit include VAT?

For UK VAT-registered businesses, cost per unit is typically calculated excluding VAT since input VAT is reclaimable. Non-VAT-registered businesses should include VAT in their cost calculations.

How can I reduce my cost per unit?

Common strategies include buying in bulk for volume discounts, negotiating better supplier terms, improving production efficiency, and reducing waste in your manufacturing or fulfilment process.
