Let’s explore the different types of inventory costs…

Procurement costs

Your procurement costs refer to the price you pay for your goods and materials, such as your packaging. Procurement costs also cover the cost to have your goods shipped to you or your fulfilment centre. Procurement costs may also cover your goods in cost, which is the process of receiving goods, booking them in, and then putting them away in the warehouse.

Storage Costs

Storage costs refer to the cost involved in storing your goods in a warehouse or fulfilment centre. If you are leasing your own warehouse, these costs will cover the storage space, electricity, staff, and any other resource within the warehouse used for the purpose of storing inventory. If you use a fulfilment centre, this overall cost will cover the same areas but it will be spread out amongst you and other clients, which generally makes it cheaper.

Insurance costs

Its always a good idea to insure your stock to help protect you in case your stock becomes damaged or stolen, but the cost of your insurance will vary depending on the sector you are in, and depending on the insurance company you use. It is always recommended to insure your stock during transit and storage to ensure you are not left out of pocket should something go wrong.

Dead/obsolete stock costs

If you have good inventory management systems and processes in place, you hopefully won’t have to deal with too much dead/obsolete stock. However this is still a cost that cannot be overlooked. Sometimes there’s a sudden decrease in demand and interest for certain stock, which can’t always be helped. However, you will still have to pay to continue storing it, or to eventually have it disposed of.

Other costs to consider

Some other inventory costs to consider (if applicable) included;

  • Equipment used for handling
  • Vehicles
  • Training
  • Health and Safety
  • Inventory management software

How to calculate your inventory costs

There is a very simple formula for you to follow to help you calculate your overall inventory costs. The formula is as follows;

Inventory cost = (beginning inventory + inventory purchases) – ending inventory

We will explore an example of this in practice next…

Calculating Your Inventory Costs; An Example

Imagine you are a pet supplies company. You would like to calculate your total inventory costs over the last 12 months before you enter the next year.

You look at the inventory you had at the start of the 12 month period (beginning inventory), which you value at £40,000.

You then look at your inventory purchases for the last 12 months, which you value at £80,000.

The last thing you look at before making your final calculation is your ending inventory, which you value at £50,000. The calculation for your ending inventory is as follows;

£40,000 (beginning) + £80,000 (purchases) – £50,000 (ending) = £70,000.

Your inventory cost is therefore £70,000.

Why Is Calculating My Inventory Costs Important?

Your inventory management is one of the most important things when it comes to successfully operating, growing, and scaling your eCommerce brand, and this applies to your inventory costs as well.

Accurately calculating your inventory costs will help you make informed decisions about your business, such as; your budget, resource planning, cost reduction plans, and that pesky thing that everyone has to pay – tax.

Let’s dive into the importance of calculating these costs in more detail…

Budgeting…

Budgeting for your business is essential. Without budgets, you risk quickly eating away at profits and other resources due to lack of proper cost allocation.

Your budget is important when it comes to; your supply chain management, inventory management, stock replenishment, storage, fulfilment, materials, product development and launch, etc. Basically, every area of your business should have a budget, and this includes your inventory.

Your profit margins

Inaccurate calculation can result in you overestimating your profit margins, which can be extremely detrimental to your business as you may end up making purchases you can’t actually afford, therefore putting you in a deficit. This could also lead to things such as debt, missed payments, and incorrect pricing overall.

So, its important that you calculate your inventory costs accurately.

Tax

Everyone has to pay tax, and your inventory cost contributes to how much tax you need to pay. Incorrect calculations of your inventory can lead to incorrectly calculating the amount of tax you pay, whether that’s overpaying or underpaying.

So, proper calculation will help to ensure you are remaining compliant while also avoiding the risk of fines or legal action, which can be an absolute nightmare.

Procurement costs

Your procurement costs refer to the price you pay for your goods and materials, such as your packaging. Procurement costs also cover the cost to have your goods shipped to you or your fulfilment centre. Procurement costs may also cover your goods in cost, which is the process of receiving goods, booking them in, and then putting them away in the warehouse.

What Factors Have An Impact On My Inventory Costs?

There are different factors to take into consideration when it comes to looking at what has a direct impact on your inventory costs.

For example, if it takes a long period of time to turn your inventory into a sale, then your costs will be higher due to the storage fees associated with holding your stock for a long period of time.

There are other factors too though, which we will look at now…

Rate of sale + Lead time

As mentioned, the longer it takes for your inventory to turn into a sale, the higher your costs will be overall. This is why demand planning is another crucial component when it comes to inventory management, as demand forecasting will help to ensure you have the right amount of inventory, and this helps to avoid excess costs on storage or disposal since you won’t have an excess amount of stock.

Explore our guide on demand planning here

Your order quantities and raw material costs

If you are running a business, you’ll probably know that every stock order you place is not exactly the same as the last one, and this could be due to many things, such as fluctuating demand or interest.

Regularly reviewing your inventory costs will help when placing stock orders as you will have a better understanding of what to order, and what your costs will be.

Storage costs

As mentioned, storage will account for a high fraction of your overall costs, and the more inventory you have, the higher your storage cost will be, especially if you have slow moving or dead stock.

If you’re with a 3PL, they might have a policy in place whereby slow move stocking results in a higher storage rate overall, though each company varies. These policies are usually put in place to incentivise you to sell stock quicker by any means possible. Not only this, but these policies are usually put in place to ensure they don’t lose out on money too, such as through the picking and packing stages. If you aren’t selling, they aren’t making as big a profit since they cant charge you to pick and pack orders that don’t exist.

Carrier Costs

When you place an order for inventory, you will have to also pay to have those goods transported to yourself or to your fulfilment partner. If you are placing large orders, or placing orders with suppliers that are located overseas, your costs will of course be much higher. Similarly, using fast track services can result in higher overall costs, so this is something else to take into consideration when it comes to exploring the external factors that contribute towards your overall inventory costs.

You may consider switching suppliers, or finding a supplier closer to your end destination since this can help to lower the overall costs associated with having your shipment sent to you or your 3PL.

Budgeting…

Budgeting for your business is essential. Without budgets, you risk quickly eating away at profits and other resources due to lack of proper cost allocation.

Your budget is important when it comes to; your supply chain management, inventory management, stock replenishment, storage, fulfilment, materials, product development and launch, etc. Basically, every area of your business should have a budget, and this includes your inventory.
