ABOUT TOOL IQ
Useful answers, with the working shown.
Tool IQ is a UK-built platform of free business calculators and practical guides for UK and US users. The aim is not simply to display a number, but to explain its assumptions, limitations and next decision.
PUBLISHER

CALCULATORS
How tools are built
Each calculator starts with a defined decision, formula and set of inputs. Results are calculated in the browser and paired with supporting metrics, a worked example, common mistakes and related tools. Regional counterparts use the appropriate currency and tax terminology.
- 01Define
State the formula, period and assumptions.
- 02Calculate
Handle zero values, rounding and realistic defaults.
- 03Explain
Show the relationship between the headline and supporting metrics.
- 04Verify
Run rendered-page tests before every public release.
TOOL IQ DAILY
How AI is used
AI may help research and structure a first draft. Published articles disclose that assistance and must add a useful calculation, limitation or decision path. Unstable facts require current primary or official sources. A daily schedule is never a reason to publish thin, repetitive or unverified content.
LIMITATIONS
Planning, not professional advice
Tool IQ provides educational calculations and general guidance. It does not provide accounting, tax, legal, investment or financial advice. Material decisions and formal filings should be checked with an appropriately qualified professional.
Every calculator page displays its methodology review date. Article pages display honest publication and modified dates; unchanged pages are not re-dated to manufacture freshness.
