SteadyCalculator’s calculators and articles are for general information and education only.

  • Financial and tax calculators produce estimates based on the numbers you enter and stated assumptions. They are not a substitute for advice from a qualified accountant, tax professional or financial adviser, and tax rules change.
  • Health and clinical calculators use published methods and formulas, which are stated on each page. They do not diagnose, treat or replace the judgement of a medical professional. If a result worries you, talk to your clinician.
  • Cost estimators give planning ranges from stated assumptions, not quotes. Get written quotes before committing to work.
  • Every page shows its formula and a worked example so you can check the working yourself. If you find an error, please contact us so we can fix it.
