Pricing questions, answered
How does a small business pricing calculator work?
A pricing calculator turns the numbers you already know — what you spend and what you want to earn — into the number you don't: the price to put on the invoice or the product page.
It works in three moves. First it adds up everything one sale costs you: materials, your labor hours at your hourly rate, job-specific extras, and a slice of your monthly overhead. Then it works out what the sale has to be worth so that the profit you want is still there after a card processor takes its cut. Finally it separates the part that belongs to you from the part that belongs to the state, so sales tax never gets mistaken for income.
The output is a recommended price, not a rule. It tells you what the price needs to be to hit your target. What the market will pay is a separate question, and the gap between the two is useful information: if your number comes out well above what competitors charge, the problem is usually in your costs or your hours, not your ambition.
How do I calculate my selling price?
Start by totalling your cost for one unit or one job:
Total cost = materials + (labor hours × labor rate) + other costs + overhead
Then divide — don't multiply — by what is left of the price after your profit margin and payment fees come out:
Selling price = total cost ÷ (1 − profit margin − processing fee)
With $90 of cost, a 30% target margin and a 3% fee, that is $90 ÷ 0.67 = $134.33.
Dividing is what makes the margin come out right. If you multiply your cost by 1.30 you get $117, and $117 only leaves you $23.49 after the fee, which is a 20% margin rather than the 30% you asked for. Multiplying sets a markup; dividing sets a margin. Sales tax then goes on top of the finished price, because it was never yours to keep.
What is profit margin?
Profit margin is the share of each sale you keep after costs. Divide profit by the selling price:
Profit margin = profit ÷ selling price × 100
Sell for $134.33, spend $90 on costs and $4.03 on fees, and you keep $40.30. That is a 30% margin: thirty cents of every dollar the customer pays is yours before income tax.
Margin is always measured against the price, which is why it can never reach 100% while you still have costs. It is the number lenders, buyers and accountants ask for, and the one that tells you whether volume will actually help: a 5% margin means a bad month wipes out a good one, while a 40% margin absorbs a mistake or two.
What is the difference between markup and profit margin?
They describe the same dollar of profit measured against two different things. Markup compares profit to your cost. Margin compares profit to your price.
Markup = profit ÷ cost × 100 Margin = profit ÷ price × 100
Buy an item for $60 and sell it for $100: the $40 of profit is a 67% markup on cost and a 40% margin on price. Markup is always the larger number, which is exactly why the two get confused, and the confusion is expensive. A shop that adds a 30% markup believing it earns a 30% margin is actually earning about 23%.
Use markup when you are pricing up from a supplier invoice. Use margin when you are checking whether the business can live on what is left. This calculator targets margin and reports the equivalent markup next to it.
How much should I charge for my services?
Work from the bottom up rather than copying a competitor. Decide what you need to earn in a year, divide by the hours you can realistically bill — most full-time solo operators bill 1,000 to 1,400 hours, not 2,000, because selling, admin and unpaid revisions eat the rest — and you have the labor rate to enter above.
Add your overhead per job, add a margin for the risk you carry, and you have a floor. Charging below it is paying for the privilege of working.
Then sanity-check the number against your market. If it is far above local rates, look for why: unbillable hours, a quoting habit that ignores travel and revisions, or overhead that has crept up. If it is far below, raise it. Quote the job as a fixed price wherever you can, so improving at your craft earns you more per hour rather than less.
What costs should I include when pricing a product?
Three layers, and the ones people forget are always in the second and third.
Direct costs are materials, parts, packaging, and the labor hours that go into the unit itself.
Job costs attach to the sale but not the product: shipping and delivery, payment processing, marketplace commission, subcontractors, travel, permits, samples, and an allowance for returns, breakage and scrap.
Overhead is everything that keeps the doors open whether or not you sell today: rent, utilities, insurance, software, phone, accounting, marketing, tools, vehicle costs. Add up a typical month, divide by the units or jobs you complete in a month, and give each sale its share.
Two costs get skipped most often: your own time, which belongs in labor even when you are the owner, and the time you spend not selling. Leave either out and the price looks healthy right up until the year-end numbers arrive.
