Reporting a calculation issue

To help us reproduce and fix a suspected calculation problem quickly, please include:

• The tool and mode you were using (for example, "BMI Calculator — metric")
• The exact values you entered
• The result you saw and the result you expected
• Your browser, if the problem looks like a display issue

Confirmed issues are corrected in the calculation engine and covered by a new automated test so they cannot recur silently. See our methodology page for how FitnessCalculator.net calculators are built and verified.

What we cannot help with

FitnessCalculator.net does not provide financial, legal, tax, or medical advice, and cannot interpret what a calculation means for your specific situation. For consequential decisions, consult a qualified professional.
