How to Calculate Wholesale Margin (With a Worked Example)

Before you quote a single wholesale price, you need to know your margin cold. Most sellers do a rough version in their head and get burned when a discount or a shipping cost quietly eats the profit they thought they had. This is your wholesale margin calculator in plain English: the formula, a full worked example with real numbers, and how to use it to set a floor you never price below.

Margin vs markup — do not confuse them

The single most common pricing mistake is mixing up margin and markup. They describe the same profit but from different angles, and the difference is money.

• Markup is profit as a percentage of your cost. If it costs you 5 dollars and you sell at 10, that is a 100 percent markup (5 dollars of profit on a 5 dollar cost).
• Margin is profit as a percentage of your selling price. That same deal is a 50 percent margin (5 dollars of profit on a 10 dollar price).

Buyers and retailers talk in margin. When a buyer says they need a 50 percent margin, they mean profit as a share of the retail price, not markup on their cost. If you quote thinking in markup, your numbers will not line up with theirs. Always run your own math in margin so you are speaking the same language.

The formula

Wholesale gross margin is:

(Wholesale price minus landed cost) divided by wholesale price, times 100.

That is it. The only trap is what you put into "landed cost" — and it is bigger than most people think.

Get landed cost honest first

Your margin is only as truthful as your cost. Landed cost is not the factory price; it is everything to get one unit ready to ship to a buyer:

• Factory or manufacturing cost per unit
• Inbound freight and duties, divided per unit
• Packaging and any inserts
• Per-unit fulfillment or pick-and-pack cost

If your factory price is 3.50 but freight, duties, and packaging add 1.50, your true landed cost is 5.00 — and margin math done on 3.50 is a fantasy. Get this number right before anything else.

A full worked example

Let us calculate margin for a real product from the ground up.

Step 1 — Landed cost. Factory 3.50 plus 0.80 freight and duties plus 0.40 packaging plus 0.30 fulfillment equals 5.00 landed cost per unit.

Step 2 — Wholesale price. Your Amazon MSRP is 24 dollars, and a keystone retailer needs to double the wholesale price to hit it, so your wholesale price is 12.00. (If that logic is new, MSRP vs wholesale price vs cost builds the full ladder.)

Step 3 — Gross margin. (12.00 minus 5.00) divided by 12.00 equals 0.583, or a 58 percent gross margin. You keep 7 dollars of gross profit on every unit.

That is a strong number — but gross margin is not the end of the story.

Subtract the costs gross margin hides

Gross margin ignores the costs of actually doing the wholesale deal. To know your real profit, subtract them:

• Per-order overhead — packing, label, admin, the account time. Spread across the order, this might be 40 dollars on a 24-unit order, or about 1.67 per unit.
• Shipping, if you cover it. On heavier items this can be 1 to 2 dollars per unit and quietly turns a good margin into a thin one. Decide this deliberately — should you offer free shipping on wholesale orders covers the tradeoff.
• Discounts from your tier structure. A 10 percent volume discount on the 12.00 price is 1.20 off per unit.

Run the worst realistic case for that same product: 12.00 wholesale, minus a 10 percent discount (1.20), minus 1.67 overhead, minus 1.50 shipping, on a 5.00 landed cost. Net profit per unit is 12.00 minus 1.20 minus 1.67 minus 1.50 minus 5.00 equals 2.63 per unit — a real margin of about 25 percent on the discounted price. Still profitable, but a long way from the 58 percent the gross number suggested. That gap is exactly why you calculate before you quote.

Setting your floor

Once you can run the full calculation, set a floor — the lowest margin you will accept — and never price below it. This is what makes your discount structure safe. Decide, say, that no order may fall below a 20 percent net margin. Then every tier, every discount, every shipping decision gets checked against that line. If a deal breaks it, you either raise the price, raise the MOQ, or walk away.

Your floor also drives your MOQ. A minimum order has to be big enough that per-order overhead does not crush your margin — the smaller the order, the more that fixed 40 dollars hurts per unit. How to set your MOQ uses the same numbers to show how the two decisions connect.

A quick reference calculation

To run it yourself on any product:

1. Add up true landed cost (factory + freight + duties + packaging + fulfillment).
2. Set wholesale price (often MSRP divided by 2 for keystone buyers).
3. Gross margin = (wholesale minus landed) divided by wholesale.
4. Subtract per-order overhead, shipping, and any discount to get net profit per unit.
5. Compare net margin to your floor. If it clears, quote it. If not, adjust.

The short version

Calculate in margin, not markup. Build your landed cost honestly, then work out gross margin — but never stop there. Subtract overhead, shipping, and discounts to find the real number, and set a floor you never cross. Do this once per product and you will quote wholesale prices with confidence instead of hope.

Solid margin math only pays off when you have buyers to quote. ASINBuyer handles that half — paste an ASIN and the agents find B2B buyers for your product, write the outreach, and book the calls, so the deals you price so carefully actually land in front of someone.

A margin you did not calculate is a guess. Run the numbers, set the floor, then negotiate from strength.
