Hong Life CalculatorsUnderstanding the private label MOQ break-even calculator — concept and principle
Private label sellers on Amazon, Shopify or marketplaces usually have to buy a minimum order quantity (MOQ) from a factory, plus pay for samples, logo setup or packaging design, before selling a single unit. This calculator shows how much cash goes out upfront, how many units you must sell to get that cash back, and the profit if the whole order sells.
How it is calculated
- Upfront cash = MOQ × unit cost + setup costs
- Units to break even = upfront cash ÷ (selling price − fees and shipping per unit)
- Profit if all sold = MOQ × (price − fees) − upfront cash
Unit cost is the factory price per unit. Fees and shipping per unit are the costs that occur only when a unit sells: marketplace commission, fulfilment, payment fees, delivery to the customer. The calculator treats inventory as already paid, so only these selling costs reduce each sale's contribution. Any currency works.
The principle
Buying stock is a cash commitment made in advance. Every sale returns the price minus the selling costs; that is the cash contribution that refills what you spent. Break-even is reached when the cumulative contribution equals the upfront cash. Comparing that number with the MOQ shows how much of the order is a cushion: units sold beyond break-even are profit.
Worked example
- MOQ = 1,000, unit cost = $4.50, setup = $1,500, price = $19, fees + shipping = $7.
- Upfront cash = 1,000 × 4.50 + 1,500 = $6,000.00.
- Contribution per sale = 19 − 7 = $12.
- Units to break even = 6,000 ÷ 12 = 500.
- Profit if all sold = 1,000 × 12 − 6,000 = $6,000.00.
How to read the result
Here you recover your cash after selling half the order. A break-even below about half the MOQ gives room for discounts, returns and unsold stock; a break-even close to the MOQ means almost everything must sell at full price. If break-even exceeds the MOQ, the order cannot pay back even if it sells out. Also divide break-even units by expected monthly sales to see how long your cash is tied up.
Common mistakes
- Leaving out freight to your warehouse, duties and inspection in the upfront cash.
- Underestimating per-unit fees: commission, fulfilment, storage, advertising and returns.
- Assuming every unit sells at full price, with no discounts or damaged stock.
- Ignoring the time needed to sell through, which ties up cash.
Frequently asked questions
Should I order more than the MOQ for a lower unit cost?
A lower price per unit raises profit but also upfront cash and risk. Run both scenarios and compare break-even units and profit.
What should "fees + shipping" include?
Everything that is paid per unit sold: marketplace referral fee, fulfilment fee, payment processing, packaging and delivery, plus an allowance for returns or ads if you track them per unit.
Why is unit cost not subtracted from each sale?
It is already counted once in the upfront cash. Subtracting it again would double-count it.
