What is AccountantKit?
AccountantKit is a set of free online calculators for the maths that accountants, bookkeepers, freelancers, and small-business owners do every week: adding or removing VAT, estimating take-home pay, scheduling depreciation, finding a break-even point, pricing for a target margin, comparing loans, projecting savings, totalling invoices, converting salaries, and reading business ratios.
Why rate-driven?
Most finance calculators on the web quietly assume one country's tax rates — and quietly go wrong when the law changes or a visitor arrives from somewhere else. Ours never assume. You enter the VAT rate, deduction, or interest rate that applies to you, so the same tool gives a correct answer in London, Lahore, Toronto, or Texas, this year and next.
Our promise
Free, always. Every tool is free, with no account and no usage limit.
Private by design. Calculations run entirely in your browser; the figures you type are never sent to or stored by us — safe for draft client workings.
Transparent. Every page shows its formula, so you can verify the working before you use a number.
Honest limits. These are general information tools, not tax or financial advice. For filed returns and accounts, a qualified accountant who knows your situation is irreplaceable.
What's next
We add tools as users request them. If there is a calculation you do every week that belongs here, tell us about it.
