A business can look attractive when you multiply the selling price by the number of customers you hope to reach.
One hundred and fifty orders at $35 is $5,250 in monthly sales. That is a real number. It is also only the beginning of the calculation.
Before deciding whether the idea works, find out what delivering those orders would consume.
Define one sale clearly
For a product business, that could be one typical order. For a cleaning service, it could be one visit with a specified scope. For a booking platform, it could be one completed booking on which the platform earns a fee.
Be careful with that last example: if a customer pays $100 through a platform and the platform earns a $10 commission, the $100 is not automatically the platform's revenue. Start with what the business actually earns under its commercial arrangement.
For this example, imagine a product order that brings the business $35 before its costs. The following figures are invented to explain the calculation.
| Cost triggered by the order | Amount |
|---|---|
| Product or materials | $12 |
| Packaging | $2 |
| Payment and selling fees | $1 |
| Delivery paid by the business | $5 |
| Total variable cost | $20 |
After those costs, the sale contributes $15 toward the costs of running the business.
$35 revenue − $20 variable costs = $15 contribution per order.
Contribution is useful, but it is not yet the owner's take-home profit.
Give the monthly costs somewhere to go
Suppose the model includes another $1,800 each month in fixed operating costs. These are costs that remain within the sales range being examined, such as a workspace commitment and essential monthly services.
At $15 contribution per order, it takes 120 orders to cover those $1,800.
$1,800 ÷ $15 = 120 orders.
This is the operating break-even point for the costs included in this simplified model. It does not recover the original investment. It also does not pay the owner or cover taxes, financing costs or other items unless those have been included explicitly.
Now look at how sensitive the result is to volume:
| Orders per month | Revenue | Contribution after variable costs | Result after $1,800 fixed costs |
|---|---|---|---|
| 150 | $5,250 | $2,250 | $450 |
| 120 | $4,200 | $1,800 | $0 |
| 90 | $3,150 | $1,350 | −$450 |
The original sales forecast can now be challenged. Where would 150 orders come from? How frequently would customers buy again? Could you deliver that volume without adding staff or equipment?
Count the work you were planning to do for free
If you must spend thirty minutes preparing every order, put those hours beside the forecast. At 150 orders, that is 75 hours, before customer messages, purchasing or administration.
You might choose to do some of that work yourself initially. Make the choice visible. If you will need to hire someone, estimate the cost and decide whether it changes per order or arrives as a monthly commitment. Avoid counting the same labour in both places.
A typical sale needs a believable mix
If you sell several products or service packages, calculate their contributions separately and use a realistic sales mix. A cheap item that sells frequently and an expensive package that rarely sells should not carry equal weight in an average.
Also examine cash timing. Paying a supplier before customers pay you can create a cash need even when the profit calculation looks positive. Break-even is one part of the business case, not a complete cash forecast.
You do not need to feel like a “numbers person” before starting this exercise. Begin with one clearly defined sale. Identify what it earns, what delivering it consumes and which costs are still waiting to be covered.
Calculation reference: The contribution-based break-even relationship is also explained in the U.S. Small Business Administration's break-even calculator. The example above is original and illustrative, with costs kept separate from one-time investment and cash-flow timing.
If the numbers have been the part you keep putting off, start with the sale your business would actually make. In the DECISION Bootcamp, you build the calculations for your own idea in Excel and receive private written feedback as you work through them. The aim is a business case you understand well enough to question and defend before committing your money.
