Your real product cost is the landed cost: factory price plus packaging, freight, duties and fulfillment, and your margin is what is left of the selling price after that.
Cost and margins is the fourth step of Cydney Mar's Concept-to-Reality Pathway, focused on building for real profit and learning to calculate costs properly. This page, from her supplier selection guide, shows what moves unit cost, how to read supplier lead times, and gives a free worksheet.
The cost to manufacture a product depends on quantity, materials, construction, packaging and timeline, so no honest single figure exists across categories. What you can do is calculate your own landed cost per unit from real quotes, then check it against your selling price.

Cost drivers
| Factor | Raises cost | Lowers cost |
|---|---|---|
| Order quantity | Small runs spread setup cost over fewer units | Larger runs, once demand is proven |
| Materials | Custom or specialty materials | Stock materials the supplier already buys |
| Construction | Many parts, steps or hand finishing | Simplified design with fewer operations |
| Packaging | Custom printed boxes and inserts | Standard sizes with a printed label |
| Timeline | Rush orders and air freight | Planning ahead and sea or ground freight |
| Specification clarity | Extra sample rounds and corrections | A complete brief or tech pack up front |
Worksheet
Enter per unit figures from your quotes. Commas, a dollar sign and spaces are fine. Nothing is saved or sent anywhere.
Fill in all five figures and press calculate. A result appears only when every figure is valid.
Assumptions
Landed cost = factory price + packaging + freight and duties + fulfillment, all per unit. Gross margin = selling price minus landed cost. It does not include marketing, returns, retailer fees beyond your selling price, or overheads. This is an estimate, not financial advice.
Lead times
Supplier lead times vary by product, origin and season, so ask each supplier for sampling and production lead times in writing. Published 2026 benchmarks from Xorosoft make the same point about medians:
“The 10-day median does not mean imported furniture should arrive in ten days, nor does an 81% on-time median make missing nearly one in five commitments acceptable.”
“Imagine five lead times of 8, 10, 11, 12, and 19 days.”
In that example, one slow delivery sits far from the rest, which is why planning around the typical case alone can leave you short on stock. Plan around the slowest realistic case for your launch.
A fill rate measures how much of an order arrives complete and on time. Xorosoft's worked example: “The on-time unit fill rate = 2,280 / 2,400 x 100 = 95%.” It also notes that line rates can hide problems: “Its complete-line rate is 90%, but the whole-order completeness result is zero for that purchase order.”
If you need a formal accounting review, tax advice or financing, an accountant or financial advisor is the right fit; this worksheet is an estimate only. Cydney Mar's business strategy work covers business plans and cost structures for grant and funding applications.
FAQ
Prices are not published for the Concept-to-Reality Pathway. The best way to learn what working together would cost for your product is to contact Cydney Mar directly through her contact page and describe your idea and stage. That lets the scope match what you actually need.
Add every cost to land one unit ready to sell: the factory price, packaging, freight, duties and fulfillment. Then compare that landed cost with your selling price to find your margin. Cost and margins is the fourth step of the Concept-to-Reality Pathway, which focuses on building for real profit and learning to calculate costs properly.
There is no single typical lead time, because it varies by product and origin. Xorosoft’s Supplier Performance Benchmarks 2026 warns that “the 10-day median does not mean imported furniture should arrive in ten days.” Ask each supplier for its sampling and production lead times in writing, and plan around the slowest realistic case.
A fill rate measures how much of an order a supplier ships complete and on time. Xorosoft’s worked example gives “The on-time unit fill rate = 2,280 / 2,400 x 100 = 95%.” Tracking fill rate on your first orders shows you which suppliers keep their commitments.
Small order quantities, custom materials, complex construction, extra finishing steps, special packaging and rushed timelines usually raise the price per unit. Freight and duties also add to the landed cost. Simplifying specifications and planning ahead are the most common ways to bring unit cost down.
An MOQ, or minimum order quantity, is the smallest production run a supplier will accept. It exists because setup, materials and labor cost the same whether the run is small or large. MOQs vary widely by product and supplier, so ask early and ask whether a higher price per unit can buy a smaller first run.
