How to play Break-Even Dial
Each round describes a small business in one or two sentences and asks for a number: units to break even, a margin, a payback period. Drag the dial, or use the minus and plus buttons for fine steps, then press Lock it in.
You score by how close you are. Within 3% of the answer is a bullseye worth 10 XP. Within 10% earns 7 XP and within 25% earns 4 XP. After each round you see your estimate next to the real answer and the one-line calculation. Eight bullseyes in a row add a 20 XP bonus.
The one division that runs a business
The break-even point is the level of sales where a business makes neither a profit nor a loss. To find it you need three numbers: the fixed costs that do not change with sales, the price of one unit, and the variable cost of making or delivering that unit.
Price minus variable cost is the contribution of each sale: the amount left over to pay the fixed costs. So:
- Break-even units = fixed costs ÷ contribution per unit.
- Units for a target profit = (fixed costs + target profit) ÷ contribution per unit.
- Break-even revenue = fixed costs ÷ contribution margin ratio, where the ratio is contribution ÷ price.
Margin is not markup
Buy at $80 and sell at $100 and the profit is $20. As a share of the price that is a 20% margin. As a share of the cost it is a 25% markup. The two words are used loosely in conversation, and mixing them up in a quote can cost real money.
Why a small discount needs a lot more volume
A discount comes straight out of the contribution. At a $100 price and a $60 cost, a 10% discount cuts the profit on each unit from $40 to $30. To earn the same total you need to sell a third more units, not a tenth more. That is the question to ask before any price promotion.

Accounts receivable, Decoded: What It Actually Means
Accounts receivable is the money customers owe a business for goods or services already delivered but not yet paid for. It usually comes from sending an invoice with payment terms, such as 30 days. On the balance sheet it counts as a current asset, because the business expects to turn it into cash within a year.
