Calculator disclaimer
Last updated
Every result on this site is an estimate produced from the numbers you enter. Change an input and the answer changes; enter an optimistic figure and you will get an optimistic answer.
Not professional advice
Nothing here is financial, tax, legal, accounting or business advice. We are not your accountant and we cannot see your books. For decisions with real consequences — tax treatment, entity structure, contracts, pricing agreements — talk to a qualified professional who knows your situation.
What the calculators cannot know
A calculator does not know what your market will bear, what your competitors charge, how price-sensitive your customers are, or whether a particular order is worth taking for reasons that have nothing to do with margin. It computes cost and price; the judgement is yours.
Actual profitability depends on your operations, waste, labour, taxes, fees, customer behaviour and market conditions, none of which a formula can observe.
Verify before you quote
Check any result against your own records before sending it to a customer. Where a calculator warns you — a price below cost, a discount larger than the profit, an unreachable margin — treat that as a reason to stop and check, not as noise to dismiss.
