📊

Why Your Rate Matters

A 1% difference in interest rate on a $350K loan can save or cost you over $80,000 over 30 years. Always shop around and compare offers from multiple lenders.

🩺

Understanding BMI

BMI is a screening tool, not a diagnostic. Athletes may have a high BMI due to muscle mass. Always consult a healthcare provider for a complete health assessment.

⏰

Business Day vs Calendar Day

Legal deadlines often count business days, not calendar days. This calculator uses calendar days. For business-day calculations, check your contract terms.
