Pricing is the fastest lever you have
Most small businesses treat pricing as a one-off decision — set the number, add a small markup, hope the market accepts it. But a 1% price increase, with volume held constant, typically improves operating profit by 8–11% for a healthy business. No other lever — cutting cost of goods, reducing overhead, driving more traffic — comes close. Yet founders spend hours optimising marketing and minutes on pricing. This library exists to close that gap.
Margin vs markup — the confusion that costs money
The single most common pricing error is confusing margin with markup. A shopkeeper who applies a "50% markup" on a $10 product sells it for $15 and earns a 33% margin — not 50%. Multiply that error across a product catalogue and the business is under-earning by tens of thousands a year. Every tool in this silo shows both numbers side by side so you always price against the right benchmark.
Break-even before you launch
A break-even calculation is the first thing an experienced founder runs before committing to a new product, a new location or a new hire. It answers a single question — how many units do I need to sell to cover the cost of this decision? — and turns a vague plan into a concrete monthly target. If the number is unreachable, the plan needs to change before it launches, not after.
From gross margin to net — the P&L story
Gross margin tells you whether the product itself is viable. Operating margin tells you whether the business around the product is efficient. Net margin tells you what actually ends up in the owner's pocket. The Net Profit Margin Calculator walks the full P&L waterfall so you can see exactly where revenue disappears — and which stage to attack first.
Customer economics: CLV and ROI
Once a business is running, the two numbers that decide whether it scales are Customer Lifetime Value (how much a customer is worth over their entire relationship with you) and Return on Investment on the marketing spend that acquired them. A healthy business runs a CLV:CAC ratio of at least 3:1 and can quote ROI on every major spend. The CLV and ROI calculators give you both in seconds.
How to use this silo
If you're pricing a single new product, start with the Product Pricing Calculator — it builds a price from materials, labour, overhead and target margin. For existing products, use Profit Margin and Markup to sanity-check. For business planning, run Break-Even and Net Profit Margin. For growth decisions, use ROI and CLV. Every tool below is designed for one job and gives its answer the moment you finish typing.
