How to use the financial calculation toolbox

The financial calculation toolbox calculates inputs only in the current browser; it does not retrieve quotes online, save credentials, or write to persistent storage.

  1. Select mode

    Choose interest rate conversion or multi-formula pricing comparison.

  2. Input parameters

    Enter the interest rate, period, and fixed variables permitted by the safe expression.

  3. Check formula

    View the intermediate results and formula explanations, then review them again against the actual contract or quotation.

Limitations and Notes

  • This tool does not provide real-time interest rates, securities valuations, bank quotes, tax advice, or investment advice.
  • The pricing formula allows only restricted operators and variables; it does not use eval or execute user code.
  • Floating-point results and rounding rules must be confirmed against the target contract, interest calculation dates, and the institution’s standards.

FAQ

Does it query the current bank interest rates?

No, all input is provided by the user.

Can it run arbitrary JavaScript formulas?

No; it uses a secure expression parser and supports only the variables and operators listed on the page.

Can the result be used as investment advice?

No, it is only a local calculation aid; important decisions should be based on formal contracts and professional advice.
