Report a Calculation Error
Accuracy is the most important thing we do. If you believe a calculator is producing an incorrect result, please let us know. When reporting an error, it helps to include:
- The name of the calculator (e.g. SIP Calculator)
- The exact inputs you used
- The result CalcPhi showed you
- The result you expected, with a source or reference if you have one
Send error reports to: support@blackbeltcodelabs.com with the subject line "Calculation Error — [Calculator Name]".
Verified errors are corrected within 48 hours and the correction is noted on the relevant page.
