Are your mortgage and loan calculators accurate for real estate planning?
Our mortgage and loan calculators use standard industry formulas and follow accepted amortization schedules used by banks and financial institutions. They provide accurate estimates for monthly payments, total interest, and loan terms. However, actual loan terms may vary based on credit score, down payment, and lender policies, so consult with a mortgage professional for final decisions.
How accurate are the BMI and calorie calculators for health tracking?
Our BMI and calorie calculators use established medical formulas recommended by health organizations like the CDC and WHO. The BMI calculator provides standard body mass index measurements, while calorie calculators estimate daily caloric needs based on age, weight, height, and activity level. These are reliable tools for general health tracking, but consult healthcare professionals for personalized medical advice.

Yes, our business and financial calculators are designed for professional use in business planning, investment analysis, and financial decision-making. They include ROI calculators, profit margin calculators, break-even analysis tools, and compound interest calculators. While they provide accurate estimates based on standard financial formulas, always verify important calculations with financial advisors or accountants.
