Cost Of Sales Equation

Hello All

Cost of Sales Equation

Ok. Opening Inventory + Purchases - Closing Inventory = CoS

But I seem to remember there was a much more elaborate equation than this and I can't find it (would have been Level 3 Costs and Revenues)

Something that included Sales Returns and Carriage In etc?

Does anyone know the full equation - I suspect they will trhough in a CoS with Sales or Purchase returns into the question for the Statement of Comprehensive Income :)

    You are correct - Carraige In should be added into Cost Of Sales, Carriage Out is an overhead (Distribution Cost).

    Sales Less Sales Return = Turnover
    Op. Stock + Purchases - Purchases Returns + Carraige In - Cl. Stock = Cost Of Sales

    Discounts Received would be classified as Other income, Discounts Allowed are an Overhead - not a Cost of Sale.

    Cost of Sales may include other directly attribtable expenses (like manufacturing costs incl. labour, depreciation) depending on the company's policy.

    This is how I would see it :)
