Measure candle profit from saleable batch yield, production costs and channel expenses. Work from production and sales exports to contribution by channel, then reconcile the result to operating profit.
Candle business profit is net sales less production costs, selling costs and operating overhead. Measure saleable batch yield first, then compare the dollars each channel leaves after its own costs; the retail price alone does not show which orders support the business.
An operating US candle company needs two connected views: cost per saleable candle and contribution by sales channel. The calculation below uses an illustrative completed batch, with all saleable units sold in the same month and no opening or closing inventory.
Bring the batch register, material issues, production time records, sales lines and channel expense detail. Preserve the batch ID, SKU, invoice ID, channel, sale date, units, discounts, returns and assigned costs. Separate customer sales tax from revenue and keep packaging used in production distinct from packaging added for shipment.
Match costs to what was consumed, rather than everything purchased that month. Wax bought for a future batch remains outside this completed batch calculation. Reconcile refunds and discounts to the sales register before calculating a realized selling price.
For context, IRS Publication 538 describes manufactured inventory costs as including direct materials, direct labor and relevant indirect costs. The management view here separates variable batch costs from shared fixed operating costs; the controller should bridge that view to the company's inventory accounting policy.
Saleable unit cost = Variable production cost consumed / Saleable candles produced
Channel contribution = Net sales − Variable production cost of units sold − Channel selling costs
The batch starts with 1,200 candles. Inspection rejects 60, leaving 1,140 saleable candles. Rejected units have no salvage value, and their consumed costs remain in the batch total.
| Production input | Cost (USD) |
|---|---|
| Wax | 1,800 |
| Fragrance | 900 |
| Jars and lids | 1,800 |
| Wicks | 300 |
| Direct production labor | 1,560 |
| Variable production supplies and energy | 480 |
| Total variable batch cost | 6,840 |
The saleable unit cost is $6,840 / 1,140 = $6.00. Rejection is 60 / 1,200 = 5.0% of units started. Dividing by all units started would give $5.70, understating the cost of each saleable candle by $0.30.
Put units started in B2, rejects in C2 and batch cost in D2. Use these spreadsheet formulas:
E2 = B2-C2
F2 = D2/E2
G2 = C2/B2
E2 is saleable output, F2 is saleable unit cost and G2 is the rejection rate. Format G2 as a percentage. A batch with no saleable output needs investigation; do not replace its division error with a zero unit cost.
The company sells the same finished candle through two channels. Direct sales realize $20 per candle after discounts and refunds; wholesale realizes $12. Shipping materials below are additional cartons and protective packing, separate from jars and lids already included in production cost.
| Channel | Units sold | Net sales (USD) | Production cost (USD) | Transaction fees (USD) | Fulfillment (USD) | Shipping materials (USD) | Contribution (USD) |
|---|---|---|---|---|---|---|---|
| Direct | 740 | 14,800 | 4,440 | 444 | 1,480 | 740 | 7,696 |
| Wholesale | 400 | 4,800 | 2,400 | 0 | 200 | 100 | 2,100 |
| Total | 1,140 | 19,600 | 6,840 | 444 | 1,680 | 840 | 9,796 |
If this table begins in row 2, with net sales in C and contribution in H:
D2 = B2*6
H2 = C2-SUM(D2:G2)
I2 = H2/C2
H4 = SUM(H2:H3)
I4 = H4/SUM(C2:C3)
Direct contribution is $7,696 / $14,800 = 52.0%. Wholesale contribution is $2,100 / $4,800 = 43.8%. The combined figure is $9,796 / $19,600 = 50.0%, rounded to one decimal place. Calculate the total from dollars rather than averaging the channel percentages.
These are contribution margins under the stated variable cost definition. They differ from the ledger's gross profit margin if that ledger absorbs fixed manufacturing overhead into inventory.
The physical reconciliation is 1,200 started = 60 rejected + 740 direct sales + 400 wholesale sales. The production cost reconciliation is 1,140 sold × $6.00 = $6,840, which matches the batch cost table.
The dollar check is equally important:
$19,600 = $6,840 production + $444 fees + $1,680 fulfillment + $840 shipping materials + $9,796 contribution
Assume the month's shared fixed operating expenses are $6,000, with no other operating items. Operating profit is $9,796 − $6,000 = $3,796. Those expenses include fixed factory costs excluded from this variable batch view; do not subtract them twice. Operating profit is the appropriate label before interest and income tax.
Check the treatment of containers and freight against the ledger. IRS Publication 334 distinguishes containers integral to manufactured goods from shipping or selling containers and includes inbound freight in goods costs. That distinction helps prevent the same packaging or freight invoice appearing in two expense groups.
The operations manager owns yield, material usage and labor records. Sales owns realized channel prices; finance reconciles the totals and defines which costs are variable. Review exceptions together before changing production volume or channel terms.
A wholesale order can add useful contribution when it fits available capacity. When capacity is constrained, also compare the scarce production or packing time consumed by each order. Avoid shifting volume solely because one channel has the higher percentage.

There is no universal margin that fits every candle business. Compare products and channels using the same cost definition, then check whether total contribution covers fixed operating expenses. A strong product margin can still leave little operating profit when customer acquisition, fulfillment or overhead costs are high.
Yes, the materials and production effort consumed by rejected candles must remain in the batch economics unless recovered elsewhere. Divide the batch cost by saleable output. Track unusual losses separately for investigation and reconcile their accounting treatment with the ledger.
It depends on realized prices and the cost of serving each channel. Wholesale often has a lower selling price, but larger shipments may require less packaging and fulfillment per unit. Compare contribution dollars and the operational resources each channel consumes before changing the sales mix.
No. Profit measures sales and matched expenses, while cash also depends on customer payment timing, inventory purchases and other payments. A profitable wholesale order may leave cash tied up in receivables. Review the cash position separately before committing to another production batch.
