Manufacturing in Nigeria: estimate cost per usable unit

Define the product and the production batch

Start with a specification that two production teams can read in the same way. Include material, dimensions, tolerances, packaging, quantity and the quality checks that decide whether a unit is acceptable. A cheap quote for a different specification is not a cheaper way to produce the same product.

For manufacturing in Nigeria, separate your own production estimate from a contract manufacturer's selling price. The latter can include its overheads and margin. Keep the batch size visible: setup costs spread over 500 units differently from 5,000 units, even when material cost per unit is unchanged.

Divide by usable output, not planned output

Illustration only: materials cost ₦600,000, direct labour ₦120,000, power ₦80,000 and packaging ₦100,000. These inputs total ₦900,000. For 1,000 acceptable finished units, that is ₦900 per unit; if only 900 pass inspection, it becomes ₦1,000 per usable unit. No figure here is a Nigerian market quotation.

That subtotal excludes rent, equipment wear, maintenance, finance, taxes, distribution and other costs not entered. List these separately before treating the number as a full cost or using it to set a selling price. Do not count a rejected item as both usable output and a loss.

Give imported inputs their own assumptions

Record the supplier's invoice currency, quoted conversion rate, freight and other confirmed charges for any imported input. Convert the foreign invoice once and avoid counting the same transport charge again inside a delivered local price.

Keep a second scenario for a different entered rate or yield. The purpose is to see which input changes your estimate most, not to predict tomorrow's exchange rate. A quote for a replacement component should include its specification and lead time, not just a price.

• Materials and purchased components
• Direct labour and setup time
• Power, fuel and consumables for the batch
• Packaging and quality-control costs
• Acceptable output, rejects and rework
• Overheads and delivery costs outside the subtotal

Plan quality and compliance before sale

SON describes MANCAP as its conformity programme for locally manufactured products against relevant Nigerian standards. Check the applicable product requirements with SON. Where NAFDAC regulates the product, consult its current category guidance as well; one approval should not be assumed to replace another.

Keep production and inspection records with the specification version used for the batch. If a complaint arises, those records help identify what was produced and checked. This guide is a costing worksheet, not a certification procedure, safety assessment or promise of profitability.
