Reference & details

How it works

Price from contribution target

Separate variable cost per unit from costs charged once per order.

Unit floor = ceil-to-cent[(unit cost + order costs / units per order) / (1 − fee fraction − target fraction)]

Order contribution

Use the net item price after discounts and exclude collected taxes.

Contribution/order = price × units × (1 − fee fraction) − unit costs − order costs

Period result and threshold

Use fixed costs and a target for the same period as the order volume.

Operating result = orders × contribution − fixed costs; target orders = ceil((fixed costs + target profit) / contribution)

Example Scenarios

$8 unit cost, two units per order, $4 order cost, $0.30 fixed fee, 3% sales fee and a chosen 30% contribution target.

→ The modeled unit price is $15.15, with $30.30 item revenue and about $9.09 contribution per order.

Sell two units per order at $20 each with the same costs, 100 orders, $1,000 fixed costs and a $1,000 operating-profit target.

→ $850 operating profit; 55 orders to break even and 109 orders for the target.

Common Mistakes to Avoid

Using the advertised rate without fees

Include origination fees, PMI, and closing costs in your total cost comparison.

Ignoring inflation or tax changes

Long-term projections should account for inflation and consult current tax rules for your region.

FAQ

No. It meets the entered contribution target under the model assumptions. Customer demand, alternatives, capacity, taxes, returns and actual provider terms need separate review.

It is the share of net item revenue left after entered unit, order and payment costs. Fixed overhead still needs coverage; the result is not net-profit margin.

The fixed charge applies per order and the percentage applies to net item sales before provider-specific rounding. Fees on tax, shipping, refunds or other bases need a documented separate adjustment.

The model rounds up to the next cent needed to meet the target. A zero-cost case uses a minimum positive unit price of one cent.

The operating loss remains visible. A positive fixed-cost or profit target is unreachable with nonpositive order contribution; more such orders do not fund the target.

No. It is the mathematical minimum whole-order quantity under the entered assumptions. Compare it with capacity and observed demand.
