What to Include in a Bug Report
If a calculator's result looks wrong, the fastest way to get it fixed is to tell us exactly what you entered and what you expected. Include which calculator you were using (for example, the mortgage amortization calculator or the fix-and-flip profit calculator), the input values you typed in, the result the page showed you, and what number you expected instead. That lets us reproduce the issue directly rather than guessing at it.
What We Can Help With
- Bug reports or issues with a calculator's results or formulas
- Feature requests for new calculators, new inputs, or new outputs on an existing one
- General feedback about the site, its content, or its usability
- Partnership or advertising inquiries
What We Cannot Help With
We do not offer financial, tax, or legal advice, and we cannot review your specific property, loan offer, or investment decision. PropCalc is an educational tool, and every result it produces is an estimate built from the numbers you enter — not a recommendation. For a decision involving real money, please consult a licensed financial advisor, tax professional, or real estate professional who can look at your full situation.
