Definition
Product cost is the sum of all direct and allocated expenses a seller incurs to put a specific unit of goods up for sale and deliver it to the buyer. It includes purchase price, logistics, packaging, marketplace commissions and expected costs for returns and storage.
How cost is calculated: components and calculation order
To obtain an accurate product cost you need to account for all cost types and allocate fixed overheads per unit. A simple calculation algorithm:
- Gather direct costs per unit: purchase price, inbound transport, packaging.
- Add variable service expenses: marketplace commission, delivery fee (if paid by the seller), acquiring fees for card payments, logistics commissions.
- Allocate indirect costs: warehouse storage, rent, staff salaries, marketing and returns — to a per-unit amount.
- Include a reserve for defects and warranty costs where relevant for the category.
Formula in simplified form:
Cost = Purchase price + Logistics + Packaging + Commission + Share of storage + Share of returns + Other expenses
Important: marketplace commission is calculated from the selling price, and storage share and other indirect costs should be allocated based on the product's turnover.
Why a seller needs to know product cost
- Margin control — without an accurate product cost you can’t tell if an item is profitable at the chosen price on Kaspi.kz.
- Correct pricing — you can set the minimum acceptable price, and account for discounts and promotions.
- Managing promotions — cost calculation shows how much of the discount and fees you cover when joining Kaspi sales.
- Assortment decisions — slow-moving items with high cost should be replaced or optimized.
- Stock planning — factoring storage and seasonality reduces costs and the risk of markdowns.
Examples of calculations on Kaspi.kz: practical breakdown
Below are two realistic scenarios with sample numbers for sellers in Kazakhstan. All values are in tenge (KZT).
Example 1. Smartphone accessory (case)
- Purchase price from supplier: 600 KZT per unit.
- Inbound logistics (consolidation + transport to warehouse): 40 KZT per unit.
- Packaging and labeling: 25 KZT per unit.
- Marketplace commission: assume 10% of selling price. If target selling price is 1,200 KZT, commission = 120 KZT.
- Acquiring fee: 1.5% of payment amount = 18 KZT (at 1,200 KZT).
- Allocated share of storage and overheads: if monthly warehouse + overheads for the SKU group are 100,000 KZT and you expect to sell 2,000 units that month, share = 50 KZT per unit.
- Reserve for returns and defects: historical return rate 2% × estimated handling cost 80 KZT => reserve ≈ 1.6 KZT per unit (round to 2 KZT).
Calculation (rounded):
- Purchase: 600 KZT
- Logistics: 40 KZT
- Packaging: 25 KZT
- Commission: 120 KZT
- Acquiring: 18 KZT
- Storage & overhead share: 50 KZT
- Returns reserve: 2 KZT
Total cost ≈ 855 KZT per unit.
With a selling price of 1,200 KZT the gross margin before other marketing expenses is 345 KZT (about 28.8%). Use this to decide on discounts or participation in Kaspi promotions.
Example 2. Small household appliance (portable blender)
- Purchase price: 6,500 KZT per unit.
- Inbound logistics: 300 KZT.
- Packaging and foam inserts: 150 KZT.
- Marketplace commission: assume 12% of selling price. For a selling price of 10,000 KZT commission = 1,200 KZT.
- Acquiring fee: 1.5% = 150 KZT (at 10,000 KZT).
- Allocated storage & overheads: larger item occupies more space. If monthly overheads are 400,000 KZT and expected monthly sales are 200 units, share = 2,000 KZT per unit.
- Returns and warranty reserve: historical combined rate 5% × average cost to handle and refurbish/dispose = 500 KZT => reserve = 25 KZT per unit (5% of the per-unit handling cost value). Often you include a higher buffer for electronics.
Calculation (rounded):
- Purchase: 6,500 KZT
- Logistics: 300 KZT
- Packaging: 150 KZT
- Commission: 1,200 KZT
- Acquiring: 150 KZT
- Storage & overhead share: 2,000 KZT
- Returns/warranty reserve: 25 KZT
Total cost ≈ 10,325 KZT per unit.
At a sales price of 10,000 KZT this SKU would be sold at a loss, so you need to increase price, reduce costs, or renegotiate supplier/fulfillment terms.
Practical tips to reduce cost and increase margin
- Negotiate better prices or minimum order quantities with suppliers; even modest discounts scale across volume.
- Optimize packaging: lighter, smaller packages reduce logistics and can lower Kaspi fulfilment fees.
- Consolidate shipments and plan purchase runs to reduce inbound transport per unit.
- Improve product listings (photos, descriptions, specs) to lower return rates and increase conversion.
- Automate repetitive warehouse tasks to reduce labour costs per unit.
- Test Kaspi fulfilment versus self-fulfilment to choose the more cost-effective model for the SKU.
Control, reporting and automation
Set up a simple per-SKU P&L in your accounting or ERP system that includes all the cost items from the formula above. Key practices:
- Track cost components monthly and recalculate allocated overheads when turnover or assortment changes significantly.
- Use mass price update tools or API integration with Kaspi.kz to apply corrected prices quickly.
- Run regular reports on returns, commissions, and storage days to spot trends that affect cost.
- Automate data import from logistics and warehouse systems to avoid manual errors in per-unit cost calculations.
Typical seller mistakes and how to avoid them
- Ignoring indirect costs — leads to underestimating real cost and false profitability. Always allocate overheads.
- Using invoice price as sole metric — you must add logistics, fees and reserves to get the true cost.
- Failing to update costs after supplier or tariff changes — set alerts for price changes and re-run calculations.
- Not simulating promotions — before joining a Kaspi sale, model the impact of discounts plus increased commission/fulfilment on margin.
Short checklist for quick cost calculation on a single card
- Enter purchase price per unit.
- Add inbound logistics and packaging per unit.
- Decide target selling price and calculate marketplace commission and acquiring fees.
- Add allocated share of storage and overheads (based on expected monthly sales).
- Add reserve for returns and defects.
- Compare total cost to selling price and adjust margin, price or costs accordingly.
Conclusion
Knowing the true product cost is essential for profitable selling on Kaspi.kz. Build a repeatable algorithm, keep data updated, and use automation where possible. Regularly review supplier terms, logistics flows and product performance to reduce cost and protect margin while staying competitive on the marketplace.
Часто задаваемые вопросы
- How to account for Kaspi.kz commission when calculating product cost and what details should I watch?
- Commission is accounted for as a percentage of the selling price and should be included in the variable costs per unit; any fixed fees (listing, promo fees) must also be allocated to sold units. Pay attention to additional charges for logistics, acquiring and targeted promotions — they reduce net margin. When calculating, fix the selling price first, then subtract all commissions to assess real profit.
- How to correctly allocate indirect costs (warehouse, salaries, marketing) per unit?
- Choose an allocation driver, e.g. number of units sold, warehouse area occupied, or turnover per SKU, and divide total costs for the period by the corresponding quantity of units. For items with different turnover rates use separate allocation coefficients so that slow-moving SKUs are not undercosted. Review allocation at least quarterly or when assortment changes materially.
- How to include a reserve for returns and defects when calculating product cost?
- Analyze the historical return rate for the category and multiply it by the average handling and return cost to get a per-unit reserve. Also include expected markdown/disposal costs for defects and expenses for inspection and repackaging. Adjust the reserve regularly based on actual data and reflect it in cost when making pricing decisions.
- What to do if the purchase price changes — how quickly to recalc cost and prices on the marketplace?
- Recalculate cost using the new purchase price, add unchanged variable costs and the updated share of indirect expenses; then adjust the target markup to maintain your margin. On Kaspi.kz use bulk price update tools or ERP/accounting integration to avoid manual updates. Before mass changes run a profit simulation and check the impact on competitiveness.
- What quick steps can reduce cost without quality loss?
- Negotiate with suppliers on price and minimum order quantities, optimize packaging and consolidate shipments to lower logistics cost. Reduce returns via improved product cards and quality checks at receipt, and automate routine warehouse operations to cut labor costs. Simultaneously test marketplace fulfilment options and your own channels to choose the most profitable model.
