Business Calculators — Pricing, Fees and Return, Worked Out
Business calculators work out the money decisions a small business or freelancer makes regularly: what to charge, what a marketplace takes from each sale, what ad spend has to return to break even, and whether a customer is worth what it costs to win them. Each one shows its inputs, the formula and the result steps.

Running a small business means answering the same money questions repeatedly, and the answers rarely survive on intuition. What does a sale have to be worth before a marketplace takes its cut? How much can be spent to win a customer before the relationship stops paying for itself? Which price holds a margin once processing fees land? This section collects focused calculators for those decisions. Each one shows every input it uses, the formula it applies and the steps between the two, so a figure can be checked by hand rather than trusted because a page produced it. Nothing is estimated silently, no growth curve is assumed on your behalf, and every result carries the same reminder: these are planning estimates, not financial advice. Fees belong to whoever charges them and change on their schedule, so the fee schedules used here are dated and labelled, and a calculator that cannot know your rates asks you for them instead of guessing. All arithmetic runs in your browser, so your costs, margins and customer figures never leave your machine.
Formats and limits are described per tool; each tool page states the ones that tool actually accepts and enforces.
Working out what a sale is worth before you set a price
This category starts from one uncomfortable fact: a price that looks healthy on a listing page can leave nothing behind once the money has moved. The questions here all work backwards from what you keep. What does a sale have to return before an advertising budget has paid for itself? How much of the revenue survives a marketplace's fees and a processor's percentage? And is a customer worth what it cost to win them? Each calculator that answers one of those questions is being written and reviewed now, and will appear on this page once it has passed that review; until then the arithmetic is described here in enough detail to be done on paper, with the same rounding a calculator would apply.
Start with the money a campaign has to return. Divide one by your gross margin as a decimal and you have the break-even return on ad spend: at a forty per cent margin, every unit of spend must produce two and a half units of revenue before the campaign has paid for itself, and a ratio that sounds respectable can still sit below that line. Then subtract what leaves as fees and processing, because attributed sales arrive before those costs and a revenue figure is not a profit figure. Only after both are settled does a price make sense.
The most expensive mistake is pricing from a competitor's page instead of from your own numbers. A close second is comparing a lifetime value built on a multi-year assumption against an acquisition cost taken from a single month, which is not the same question and produces a ratio that flatters the business. Rounding is quietly consequential too: a per-sale charge rounded down across a thousand sales is a real loss, so any figure worth using is worth showing its intermediate steps.
Work in the order the money arrives, and change one assumption at a time, because moving two figures together means you can no longer tell which one did the work. A caution that applies to everything in this section: none of these sums knows your business. They apply arithmetic to the numbers you supply, and those numbers are assumptions until an invoice confirms them. Treat a result as a plan to test, not as a fact, and revisit it when the underlying rates change, since advertising costs and marketplace fees move on somebody else's schedule rather than yours.
When this category is NOT the answer
If the question is a household sum rather than a business one - a loan, a discount, a date difference - the Calculators section covers it without the business framing. If the work is the listing itself, the Creator tools build the title and description that carry the price. And when the figure is for a tax filing or an investment decision, the arithmetic here is not a substitute for a professional's judgement.
Frequently asked questions about Business tools
Are these results financial advice?
No. Every page says so above and below the result. They are arithmetic on the figures you enter, meant for planning and sanity-checking; a decision about pricing, spending or borrowing is yours, and an accountant or adviser is the right person for it.
Where do the fee percentages come from?
From the marketplace or payment processor's own published schedule, which is dated in the page's limitations so you can see when it was checked. Providers change fees on their own timetable, so verify the current rate before relying on a figure.
Do you store my costs or customer numbers?
No. Everything is calculated in your browser and held only while the page is open. Refreshing clears it, and no figure is sent anywhere.
Why do some calculators show a warning instead of a number?
Because the inputs describe something impossible or undefined: a zero denominator, a churn rate of 100%, or a margin that leaves no room. The page names the reason rather than printing a misleading figure.
