Reporting a formula error — what to include

Formula errors are the most important messages we receive. If you think a calculator is giving incorrect results, the following information helps us investigate quickly:

🔗URL of the tool — e.g. gentoollab.com/tools/compound-interest-calculator/
🔢Inputs you used — the exact values you entered in each field
❌What result you got — the output the calculator showed
✅What you expected — the correct result, or a reference source showing the right answer

What we can't help with

GenToolLab is a tool site, not a professional advisory service. We are not able to:

  • Provide personal financial, tax, investment, or accounting advice
  • Provide personal medical, dietary, or clinical advice
  • Interpret calculator results for your specific situation
  • Provide legal advice of any kind

For professional advice, please consult a qualified financial adviser, accountant, physician, or solicitor/attorney as appropriate.
