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?

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.
