Supplier Order Break-Even Calculator

Reverse-solve a supplier commitment from the economics of units actually sold. Supplier price, freight, duty, defects, marketplace fees, fulfillment, expected sell-through, markdown recovery, holding cost, and fixed sourcing costs determine contribution per sale, break-even sold units, gross units that must be ordered, break-even sell-through for the MOQ, margin of safety, and capital at risk.

Supplier commitment decision

Test the MOQ against sellable yield and realistic sell-through

  1. Enter the supplier MOQ, planned order quantity, and cash landed cost for every ordered unit.
  2. Remove defects to identify the good units available for full-price sale or leftover recovery.
  3. Calculate net proceeds after selling fees and fulfillment for units sold at full price.
  4. Assign a conservative recovery value and holding or disposal cost to leftover good units.
  5. Reverse-solve the order quantity and MOQ sell-through required to repay fixed sourcing and launch costs.

Break-even symbols

Physical yield, commercial sell-through, and fixed cost are separate gates

QOrdered quantity (units).
QminSupplier minimum order quantity (units).
zDefect rate (decimal).
sFull-price sell-through of good units (decimal).
CLanded cash per ordered unit (currency/unit).
PFull customer selling price (currency/unit).
fSelling fee as a share of price (decimal).
uFulfillment cost per sold unit (currency/unit).
RNet recovery per leftover good unit (currency/unit).
FFixed sourcing and launch cost (currency).

Detailed calculation process

Build profit per ordered unit before dividing fixed cost

Good-rate = 1 - z
Net full-price proceeds = P * (1 - f) - fulfillment
Net leftover recovery = P * recovery rate - holding cost
Profit per ordered unit = Good-rate * [s * net sale + (1 - s) * net recovery] - C
Required ordered units = F / profit per ordered unit
Break-even sold units = Required ordered units * Good-rate * s
MOQ break-even sell-through = [C + F / Q_min - Good-rate * R] / [Good-rate * (Net sale - R)]
Planned profit = full-price proceeds + leftover recovery - purchase cash - F

Worked default commitment

The 2,400-unit plan is below break-even at 72% sell-through

The default has a 1,800-unit MOQ, $12.05 landed cash per ordered unit, 3.5% defects, a $31.50 selling price, 16% selling fee, $4.10 fulfillment, 72% sell-through, $7.57 net leftover recovery, and $16,500 fixed sourcing and launch cost.

Net full-price proceeds = $31.50 * 0.84 - $4.10 = $22.36
Good-rate = 1 - 0.035 = 0.965
Net leftover recovery = $31.50 * 0.28 - $1.25 = $7.57
Profit per ordered unit = 0.965 * [0.72 * $22.36 + 0.28 * $7.57] - $12.05 = $5.53
Required ordered units = $16,500 / $5.53 = 2,983.1
Break-even sold units = 2,983.1 * 0.965 * 0.72 = 2,072.7

The planned order sells about 1,667.5 units and produces approximately -$3,225 after fixed cost. The MOQ itself would require about 97.5% sell-through to break even, so the correct response is to improve economics or reconsider the fixed launch burden—not merely order the minimum.

Negotiation levers

Change the gate that actually binds

  • Amortize tooling over a documented multi-order commitment
  • Negotiate MOQ separately from unit quote
  • Reduce defects with pre-shipment inspection
  • Secure channel placement before ordering
  • Model liquidation proceeds from comparable inventory

Break-even limitation

Sell-through is not a cash-timing forecast

The model does not schedule sales, supplier deposits, collection lag, storage-duration changes, markdown timing, repeat orders, taxes, or currency movements. Use the supplier order forecast for timing and a cash-flow plan for liquidity.

Supplier order break-even FAQ

Questions about MOQ, leftovers, and fixed cost

Can ordering more units solve a negative profit-per-unit problem?

No. When expected profit per ordered unit is non-positive, larger orders increase the loss before fixed cost.

Why include leftover recovery?

Unsold good inventory usually has some economic outcome; explicit recovery is more honest than valuing it at full price or zero without explanation.

Should fixed sourcing cost be spread over future orders?

Only when a defensible purchasing plan commits to those orders. Otherwise test the first order on the fixed cash it must actually recover.

Practical examples

Supplier Order Break-Even Calculator in real planning situations

  • Check whether a supplier MOQ can repay tooling and compliance costs.
  • Measure the break-even effect of lower sell-through.
  • Compare full-price contribution with markdown recovery on leftover stock.

Additional Supplier Order Break-Even Calculator questions

Why is MOQ not automatically the order recommendation?

MOQ is a supplier constraint; it can be below or far above the economic break-even quantity.

What happens to unsold units?

The model assigns the entered markdown recovery and holding cost rather than pretending unsold stock has no value or cost.

When is break-even infeasible?

It is infeasible when realized contribution per sold unit is non-positive or the required sell-through exceeds 100%.
