True Unit Cost
Your variable cost per sale plus its fair share of fixed costs — the real cost of one unit.
What this book teaches
The seven numbers that decide whether a small business makes money — in plain arithmetic, no algebra, no jargon. Tell revenue from profit, add up the true cost of a sale, untangle markup from margin, price for profit on purpose, find your break-even, watch cash as closely as profit, and set money aside for tax before it's a shock. Then a full capstone story ties it all together — one real business deciding what to keep, what to cut, and when.
Free tools for this book
Markup ↔ Margin
Flip between markup and margin, and price to a target margin. The number that trips up every seller.
Price for Profit
True cost + target margin → the price that leaves you money, and the floor you must not cross.
Break-Even
Fixed ÷ contribution = how many you must sell, the revenue, and your margin of safety.
Cash Runway
How long your cash lasts at your monthly burn — why a profitable month can still run out.
Tax Set-Aside
Park the right share of profit — you pick your own rate — so the bill is never a shock.
Cost of a Discount
New contribution after a markdown, and how many more you must sell to make the same money.
Small-Business Toolkit
Every formula and a fill-in worksheet, gathered and sized to print. No sign-up.
