The best way to price a product is a three-check system: cost-plus sets your floor (total unit cost ÷ (1 − target margin)), competitor pricing sets your range (what similar products actually sell for), and value-based pricing sets your ceiling (what the product is worth to the buyer). Your final price should sit above the floor, inside the range, and as close to the ceiling as your positioning allows. Sellers who only do the first check leave 20-40% of their margin on the table; sellers who skip it go out of business.
This guide walks through the exact formula with a fully worked $26.55 example, every cost line people forget (including the card fee that depends on the price itself), the three pricing methods and when to use each, price-ending psychology, and a margin-vs-markup table that clears up the most common pricing mistake in small business.
Add every cost that goes into one unit — materials, labour, packaging, shipping, fees, and a share of overhead — divide by your target cost-of-goods percentage (price = cost ÷ (1 − margin)), then sanity-check against competitor prices and the value the buyer gets. Cost-plus sets your floor, competitor pricing sets the range, value-based pricing sets the ceiling.
Price = total unit cost ÷ (1 − target margin). A $26.55 total cost at a 33.5% target margin gives $26.55 ÷ 0.665 ≈ $39.93, rounded to $39.95. To use retail markup instead, multiply unit cost by (1 + markup) — a 50% markup on a $10 product is $15, but that same $15 is only a 33% margin, because margin is profit divided by price, not by cost.
For physical handmade and e-commerce products, aim for a 30-50% gross margin; keystone pricing (a 50% margin — doubling your cost) is the traditional retail baseline. Below 20% there is almost nothing left after overhead and ads. Margins above 80% usually indicate digital products or strong brand value.
Setting the retail price at roughly double your total unit cost — a 50% margin. It has been the wholesale/retail baseline for decades because it leaves a retailer room to double their cost too. If doubling your cost feels too expensive to sell, the fix is usually lowering costs or raising perceived value — not abandoning the margin.
A 100% markup on cost (keystone, price = 2 × cost) is the traditional baseline. Established retailers typically run 50-60% markups on cost, which equals a 33-37% margin. Competing on price alone pushes markups toward 30-40% on cost (a 23-29% margin) — survivable only with high volume and low overhead.
Pricing according to the economic value the product creates for the buyer rather than the cost of making it. A $26.55 candle that anchors a $140 spa ritual, or a $125 digital toolkit that saves a business owner $300 a month, can both support prices well above cost-plus. Use it as your ceiling check: if value clearly supports more than your formula price, raise the price.
Review at least annually, and re-run the calculation whenever any input changes — materials, your own pay rate, shipping, or processing fees. A 5-10% annual increase is standard and rarely costs volume when sent as a matter-of-fact notice. Absorbing cost inflation without repricing means quietly working for free.
Here is the complete method to price a product, in five steps:
price = total unit cost ÷ (1 − margin). The division (rather than multiplying by a markup) is what guarantees the margin you picked is what you actually keep.Why divide instead of multiply? Because margin and markup are different numbers (full table below), and the division makes the maths honest: at a 40% target margin, cost is 60% of the price, so dividing by 0.60 is the only way the profit left over is exactly 40% of what the customer paid.
price = cost ÷ (1 − margin). If you remember one line from this guide, remember that one. Multiplying your cost by "1.5 for a 50% margin" is the single most common — and most expensive — pricing mistake small sellers make.Your price can only be as good as your cost number. These are the eight lines that belong in total unit cost — the last three are the ones almost everyone forgets:
Materials $8.50 + labour (30 min @ $22/hr) $11.00 + packaging $1.20 + postage $2.10 + overhead share $2.40 + card fee @ target price $1.35 = $26.55 total unit cost.
The best pricing approach for a small business is to use all three methods in a specific order: cost-plus first to find the floor, competitor-based second to find the range, value-based third to test the ceiling.
| Method | How it works | Best for | Blind spot |
|---|---|---|---|
| Cost-plus | Add your margin to total unit cost via the formula above | Setting the floor; guaranteeing profitability | Ignores what buyers will pay — can underprice high-value products |
| Competitor-based | Price inside the observed range for comparable products | Commodities and crowded marketplaces | Competitors may be losing money or have different costs |
| Value-based | Price against the value created for the buyer | Differentiated products, B2B, anything unique | Requires knowing the customer; hard to quantify for impulse buys |
Cost-plus without a competitor check produces prices that are either embarrassingly low or unsellably high. Competitor-only pricing (copying the $22 candle next door) is how sellers go broke on products whose costs differ from their rival's. Value-based pricing without a cost floor is how sellers feel rich on revenue and poor at tax time. The three-check system exists because each method corrects the blind spot of the others.
Step by step, using the five-step method:
Sell 80 candles a month at $39.95 and the margin dollars are $963/month. At the naive "$26.55 plus a bit" price of $32, they'd be $380 — the pricing decision is worth more than $7,000 a year on an 80-unit hobby business. Price is the highest-leverage number in your business, and it's the only revenue lever that requires zero extra work per sale.
Margin is profit as a percentage of the price. Markup is the amount added as a percentage of cost. They are not interchangeable, and confusing them systematically underprices everything you sell:
| Markup on cost | Price from $10 cost | True margin |
|---|---|---|
| 50% markup | $15.00 | 33.3% |
| 60% markup | $16.00 | 37.5% |
| 100% markup (keystone) | $20.00 | 50.0% |
| 150% markup | $25.00 | 60.0% |
The pattern: to earn a 50% margin you must apply a 100% markup. A seller who wants "about a 50% margin" and multiplies cost by 1.5 has actually built a 33% business — and every cost increase eats them alive from there. This one confusion is behind a large share of the "I'm selling plenty but there's never any money" stories in every maker community.
The price you calculate today is a snapshot of today's costs and today's competitor range. A pricing system — the same 8-tab workbook pattern used by accountants — keeps it current: a cost breakdown tab as the single source of truth, a pricing calculator that re-recommends prices whenever a cost changes, a margin health check per product, price-scenario modelling (what happens to profit at −10%, +10%), a competitor watch, and a break-even calculator for new products. Set an annual calendar reminder, and re-run the numbers whenever any input moves more than about 10%.
Raising a price about 10% costs far fewer customers than sellers fear — and the customers it does lose are disproportionately the least profitable ones. Repricing is the only "task" in business where an hour of spreadsheet work can out-earn a month of marketing.
Everything in this guide is built into a single workbook: the Pricing Strategy & Profit Margin Calculator. Enter each product's cost lines once, and it computes cost-plus, margin-based, and value-based price recommendations side by side, tracks competitor prices, models price scenarios with elasticity, and tells you exactly how many units a new product must sell to break even on your profit goal.
Cost-plus + margin + value-based recommendations for every product, competitor watch, price-scenario modelling, profit goals, and break-even analysis. No macros — works in Excel, Google Sheets, LibreOffice Calc, and Apple Numbers. Pre-loaded with a worked example business. One-time $11 — currently 40% off in the September sale.
