**Description:** Illustrative burden; replace with your overhead rate.

**Notes:** Extended cost = quantity per assembly x (1 + scrap allowance) x unit cost. Check results against the cost rollup in your ERP before loading standard costs.

## Content

**Intro:** Before you load standard costs into a new ERP, you want a quick independent check of the roll-up. This worksheet lets you list the components, apply a scrap allowance and see the extended and total material cost, then export the table to Excel.

**Sections:**

#### How to use it

**Body:** Replace the sample rows with your components, units of measure and quantity per assembly. Enter a scrap allowance for each line where yield loss is expected, such as bar stock and cut-to-length materials. Unit costs come from your latest purchase prices or approved standard costs. The total updates as you edit, and you can add rows for sub-assemblies or additional components.

#### Method

**Body:** Each line costs quantity x (1 + scrap / 100) x unit cost. The sum of lines is the rolled-up material cost, and the summary shows a burdened figure using an illustrative overhead rate. Real systems also roll up labour, machine and overhead through routings, and multi-level BOMs add the cost of each child assembly, so use this for single-level checks and spot audits.

**Bullets:**

- Keep units of measure consistent with purchasing units.
- Use yield-based scrap for materials, fixed for fasteners.
- Record the cost date so the check is traceable.

#### Common mistakes

**Body:** Mismatched units of measure are the classic error, such as costing per metre while the BOM consumes millimetres. Others include double-counting scrap that the routing also applies, and using last price for some parts and average cost for others. Compare against the ERP rollup and investigate any line that differs.

**Cta:** Netray can compare your ERP cost rollups with your purchasing data and highlight outliers.

**Faq:**

#### Does this do multi-level BOMs?

**Answer:** It handles one level at a time. For multi-level products, roll up each sub-assembly separately and enter its cost as a component line in the parent.

#### What scrap percentage should I use?

**Answer:** Use measured yield loss from production or supplier data. For standard costing, many companies review scrap factors annually as part of the cost update.

#### Can I export it?

**Answer:** Yes. The worksheet exports to Excel, CSV and PDF, so you can share it or use it as a reference during a cost review.

#### Is this a cost accounting tool?

**Answer:** It is a simple check. Full costing includes labour, machine rates, overhead and variances, which belong in your ERP's costing module.
