About our business
Business calculators put the numbers behind running a company or a freelance practice within reach — the hourly rate you actually need to charge, the revenue and gross profit a sales plan produces, and the cash flowing in and out over a period. These are the figures that decide whether a business is sustainable, yet they are the ones owners most often estimate loosely or avoid, which is how underpricing and cash crunches take hold. Freelancers use a rate calculator to translate a target income into a defensible hourly or day rate after accounting for unbillable time, expenses and taxes; small-business owners project revenue and margin before committing to a pricing strategy; and anyone managing money watches cash flow to make sure obligations are covered as they fall due. The methods here are the standard ones from business finance — grossing income up for tax and overhead, revenue as units times price, cash flow as inflows minus outflows — and each tool shows the formula and a worked example so the logic is transparent rather than hidden. The important limitation is that these are planning tools, not accounting or tax advice: real tax rates, allowable expenses and payment timing vary by jurisdiction and situation, and the figures you get are only as good as the assumptions you feed in. Use them to price with confidence and to spot problems early, then confirm the specifics with an accountant.
Common questions about business
How do I know what to charge as a freelancer?
Start from the take-home income you need, then gross it up to cover the taxes, business expenses and unbillable hours a salaried employee never sees. Because you cannot bill every working hour — admin, sales and downtime eat into the week — your rate has to be higher than a simple salary-divided-by-2,080 figure. The freelance rate calculator does this arithmetic for you; be honest about how many hours you can realistically invoice, as that number drives the result.
What is the difference between revenue and profit?
Revenue is the total money coming in from sales — units sold multiplied by price — before any costs. Profit is what remains after those costs are subtracted, so a business can post high revenue and still lose money if costs run higher. Gross profit subtracts the direct cost of the goods sold; net profit also subtracts operating expenses. Knowing which figure someone means matters, because a healthy-looking revenue number can hide a thin or negative margin.
Is cash flow the same as profit?
No, and confusing the two sinks otherwise profitable businesses. Profit is an accounting measure that can include sales you have invoiced but not yet been paid for. Cash flow tracks money actually moving in and out, on the dates it moves. A company can be profitable on paper while running out of cash because customers pay late and bills come due first. Watching cash flow, not just profit, is what keeps a business solvent day to day.
