What you will learn
- Separate variable costs from fixed costs.
- Calculate contribution and a simplified break-even point.
- Test whether a price can support delivery and make sense to a buyer.
Count the full work of delivery
Begin with one clearly defined unit: one item, session, repair, or monthly service package. List the resources needed to deliver it, including materials, packaging, payment charges, travel, preparation, customer communication, and likely rework. Include your time rather than treating it as free because you own the business. Decide what is included in the offer so that the unit means the same thing each time. Keep one-time setup expenditure separate from recurring operations. Estimates are acceptable at an early stage if labeled and later checked. A price based only on visible materials can look profitable while quietly failing to support the work.
Separate contribution from profit
Variable costs change with the number of units delivered; fixed costs remain broadly unchanged over the relevant period and operating range. In a simplified example, a service priced at 50 currency units has variable cost of 20, including delivery labor. Each sale contributes 30 toward fixed costs and then profit. With monthly fixed costs of 600, the simplified break-even quantity is 600 divided by 30, or 20 completed sales. This calculation assumes the price and unit costs remain stable and every counted sale is delivered and paid. Contribution is not profit, and revenue is not money you can automatically spend.
Check capacity and less favorable cases
Break-even arithmetic is only useful if the required volume is plausible. If each service takes three hours and you have thirty available delivery hours, you can complete ten units, not twenty. The current arrangement cannot reach the example’s break-even quantity within that capacity. You would need to reconsider the price, costs, scope, capacity, or idea itself. Test a lower sales volume and higher cost estimate. Include cancellations, delays, and unpaid administrative work where relevant. Cash timing also matters: paying suppliers before customers pay can create pressure even when the eventual calculation looks positive. Do not confuse an accounting estimate with available cash.
Connect the arithmetic to a real offer
Costs help identify what delivery requires, but do not establish what customers will pay. Compare relevant alternatives and investigate the benefit the buyer recognizes. Define the scope, payment terms, and any extra charges clearly. A price increase may require better targeting or a more valuable offer; merely wanting a margin does not create demand. Run a transparent, bounded test and record actual delivery time and costs. Recalculate when the scope changes. The worked numbers in this lesson are educational examples, not a recommended price or individualized financial advice. Local tax, reporting, and commercial obligations require appropriate context beyond this simple model.
Check whether a discount changes the required volume beyond what you can deliver. In the example, reducing price to 40 while variable cost remains 20 leaves contribution of 20, so covering 600 requires 30 sales. Lower prices do not automatically improve the business merely because more people might express interest. Demand and capacity still need evidence.
Fictional case: Leo discovers a capacity problem
Leo offers document-formatting sessions for 50 units. He initially counts only 5 units of software and transaction costs. Tracking the whole process reveals preparation, messages, revisions, and delivery labor, bringing his variable cost estimate to 20. With fixed monthly costs of 600, he needs twenty sessions under the simplified model. Yet his available time supports only ten. He does not solve the problem by assuming demand will double. He narrows the included revisions, investigates a different customer group, and tests a revised offer before committing to recurring expenses. The calculation exposes a decision that enthusiasm had hidden.
Build a simple price-and-capacity model
- Define one saleable unit and list variable costs, including labor.
- List recurring fixed costs separately from setup costs.
- Calculate contribution and simplified break-even quantity, then compare with capacity.
- Test a less favorable case and write what customer evidence is needed before choosing a price.
