Wholesale Cost Calculator

Inputs

Large screens show three columns, then two, then one.

Currency

Unit cost from supplier

Cost per item before shipping and fees.

Quantity

Used to compute per-unit landed cost.

Supplier discount (%)

Applied to unit cost before totals.

Shipping (fixed)

Freight, courier, or forwarding charges.

Duties / customs (fixed)

Import duties, brokerage, clearance.

Packaging (fixed)

Boxes, inserts, labels, pallet wrap.

Handling / labor (fixed)

Receiving, prep, kitting, QC time.

Other fixed costs

Insurance, storage, misc order costs.

Payment fee (%)

Applied to subtotal (goods + costs).

Overhead allocation (%)

Admin, rent, tools, and support costs.

Wastage allowance (%)

Damage, defects, shrink, spoilage buffer.

Tax / VAT (%)

Applied after fees in this model.

Target gross margin (%)

Used for suggested wholesale price.

Retail markup multiplier

Retail = wholesale × markup (e.g., 2×).

Notes (optional)

Formula used How to use

Formula used

Discounted unit cost = UnitCost × (1 − Discount%)
Goods cost = DiscountedUnitCost × Quantity
Fixed costs = Shipping + Duties + Packaging + Handling + Other
Overhead = (GoodsCost + FixedCosts) × Overhead%

Wastage = GoodsCost × Wastage%
Subtotal = GoodsCost + FixedCosts + Overhead + Wastage
Payment fee = Subtotal × Fee%
Tax = (Subtotal + PaymentFee) × Tax%
Total landed = Subtotal + PaymentFee + Tax
Cost per unit = TotalLanded ÷ Quantity
Wholesale price = CostPerUnit ÷ (1 − Margin%)

This model separates fixed order costs from percentage-based costs for clearer pricing decisions.

Example data table

Scenario	Unit cost	Qty	Shipping	Duties	Target margin	Est. cost/unit

Values are illustrative and will vary by supplier terms, shipping lanes, and tax rules.

Landed cost visibility

Wholesale cost is not only unit price. Most sellers add freight, duties, and prep work. A small fee can shift unit cost fast. Track landed cost before you set price. Use quantity to spread fixed costs. Higher volume often lowers cost per unit.

Discount impact on net unit cost

Supplier discounts reduce the base cost first. A 5% discount on a $10 item saves $0.50 per unit. On 500 units, that saves $250. Pair discounts with stable quality checks. Bad batches raise wastage. Wastage can remove discount gains.

Fixed costs and quantity scaling

Shipping and customs are often fixed per order. If freight is $120, then 100 units add $1.20 each. At 400 units, the same freight adds $0.30 each. This calculator shows that effect clearly. Use it to plan reorder points and cartons.

Overhead and wastage buffers

Overhead is a real cost for storage and staff time. Many teams use 3% to 10% allocation. Wastage can be 0.5% to 3% in retail goods. Fragile items may need more. Buffers protect margin. They reduce surprise losses.

Margin based wholesale pricing

Margin differs from markup. A 25% margin means profit is 25% of sale price. The calculator uses cost ÷ (1 − margin). If cost per unit is $8, then 25% margin gives $10.67. This supports consistent pricing across channels.

Price testing and export workflow

Teams review many quotes each month. Exported CSV helps compare suppliers and lanes. The PDF report is useful for approvals. Track changes by date and currency. Keep notes for lead time and terms. Fast records improve negotiation and planning.

FAQs

1) What is wholesale landed cost?

It is the full cost to get inventory ready to sell. It includes supplier price, shipping, duties, packaging, handling, fees, overhead, and tax.

2) Why does quantity change cost per unit?

Fixed costs get spread across more units. Freight and customs often stay similar per order. More units lower the fixed cost share per unit.

3) How is gross margin used here?

The calculator converts cost to price using cost ÷ (1 − margin%). This targets a margin on the selling price, not a markup on cost.

4) Should I include payment fees for wholesale orders?

Include them if you pay card or gateway fees. For bank transfer or net terms, set the fee to zero. Keep the setting aligned with real payment method.

5) What overhead percent is reasonable?

Many small stores start with 3% to 8%. Warehousing heavy models can be higher. Use bookkeeping data to refine it over time.

6) Can I use the retail estimate for store pricing?

It is a quick guide based on a multiplier. Real retail pricing depends on competition, ads, returns, and platform fees. Use it for first-pass planning.
