ToolBox provides free calculators, converters, and generators for general information and convenience. The results are estimates produced by standard formulas — they are not professional advice and are not a substitute for consulting a qualified professional.

Financial tools

The loan, mortgage, compound interest, retirement, and other finance calculators use simplified models. They do not account for every fee, tax, rate change, or contractual term, and their output is not financial advice. Before making a borrowing, investment, or retirement decision, check the figures with your lender, a licensed financial adviser, or an accountant.

Health and fitness tools

BMI, body fat, calorie, macronutrient, and related calculators are population-level screening estimates. They cannot account for individual medical circumstances and are not a diagnosis or a treatment plan. Talk to a doctor or a registered dietitian before acting on a result, especially one that concerns you.

Engineering, developer, and other tools

Electronics, embedded, developer, and text tools are provided as-is for reference and prototyping. Verify any value that matters — a resistor rating, a checksum, a converted unit — against a primary source or a second method before relying on it in production or anywhere safety-relevant.

No warranty

The tools and content are provided "as is," without warranty of any kind. To the fullest extent permitted by law, ToolBox is not liable for any loss or damage arising from use of the site or reliance on its output; your use of the tools is at your own discretion and risk. See the Terms of Use for the full statement.
