Disclaimer

These are planning tools, not advice

Everything on this site is provided for general information and planning. It is not financial, investment, tax, accounting, or legal advice, and using a calculator here does not create a professional relationship of any kind.

The calculators perform arithmetic on numbers you supply. They know nothing about your business, your market, your obligations, or your circumstances. A result is a starting point for a decision, never a substitute for one.

Results depend entirely on the inputs you give

Every output is only as good as what goes into it. Estimated inputs produce estimated outputs, and small changes to an assumption can change a result substantially — which is why several calculators tell you which input the answer is most sensitive to.

Where a calculator uses a simplified or heuristic model rather than an exact industry formula, its own page says so. Those pages are honest about it because the alternative — implying precision that isn't there — would make the tool worse than useless.

Benchmarks are directional, not authoritative

The benchmark tables and the healthy/borderline/risky thresholds on each gauge are compiled ranges reflecting commonly reported figures. They exist to answer roughly whether your number is normal for a business of your kind. They are not targets, standards, or guarantees.

Some of these figures move quickly — advertising costs and channel conversion rates in particular. Anything you plan a budget around should be checked against your own historical data first, and a current primary source second.

No warranty, and no liability for decisions

This site is provided as is. While formulas are checked against their worked examples automatically, no guarantee is made that any calculator, benchmark, or explanation is accurate, complete, or suitable for your situation.

You are responsible for decisions you make. To the fullest extent permitted by law, no liability is accepted for any loss arising from use of this site — including lost profit, wasted spend, or decisions made on the basis of a result shown here.

Decisions with real money behind them deserve your own data and, past a certain size, a professional who is accountable for the answer.

Your numbers stay in your browser

Every calculation runs client-side in JavaScript. The figures you type are never sent to a server, never stored, and never logged. There is no account, no email gate, and no step where you have to hand over anything to see your result.

Sponsorship and third-party links

Where a page carries a sponsored placement or an affiliate link, it is labelled as such. Compensation never determines what a calculator reports, what its benchmarks say, or which tools appear in its guidance.

Links to external sites are provided for convenience. Their content is outside our control and their inclusion is not an endorsement.

This page may change

As calculators are added or revised, this page is updated to match. Continued use of the site after a change means you accept the current version.
