Frequently Asked Questions

Get answers to common questions about our calculators

Q: How accurate is the mortgage calculator for different loan types?

A: Our mortgage calculator uses industry-standard formulas (amortization schedules) and supports Conventional, FHA, VA, and USDA loans. It accounts for PMI, property taxes, insurance, and different interest rates. Results are accurate for planning purposes, but actual rates and terms depend on your credit score, lender policies, and market conditions. For precise quotes, always consult with licensed mortgage professionals. Want to see how extra payments can reduce your interest? Use our Mortgage Payoff Calculator.

Q: Can I use this calculator for refinancing my home loan?

A: Yes! Our mortgage calculator works for both new purchases and refinancing. Enter your current loan balance, desired new interest rate, and loan term to see potential savings. For detailed refinance analysis including break-even points and closing costs, use our dedicated Refinance Calculator which compares your current loan with refinance options.

Q: What is the best way to estimate my in-hand salary after taxes in India?

A: Use our India Income Tax Calculator to estimate your in-hand salary. Enter your CTC (Cost to Company), deductions (80C, 80D, HRA, etc.), and choose between Old and New Tax Regime. The calculator shows gross salary, deductions, taxable income, tax liability, and final in-hand amount. It accounts for standard deduction (₹75,000 in New Regime), TDS, and EPF contributions for accurate results.

Q: How does BMI compare to body fat percentage for health assessment?

A: BMI (Body Mass Index) uses only height and weight, making it a quick screening tool but less accurate for athletes or those with high muscle mass. Body fat percentage measures actual fat vs. muscle, providing a more precise health assessment. For example, a bodybuilder may have a "overweight" BMI (25-30) but healthy body fat (8-12%). Use our BMI Calculator for general screening, then our Body Fat Calculator for detailed body composition analysis, especially if you're athletic or muscular.

Q: What are the latest income tax slabs for FY 2025-26 in India?

A: For FY 2025-26, the New Tax Regime has these slabs: 0% up to ₹3 lakhs, 5% for ₹3-7 lakhs, 10% for ₹7-12 lakhs, 15% for ₹12-15 lakhs, 20% for ₹15-20 lakhs, 30% above ₹20 lakhs. The Old Regime has higher rates but allows deductions (80C, 80D, HRA, etc.). Our India Income Tax Calculator automatically applies the correct slabs and shows which regime saves you more based on your income and deductions.

Q: How to calculate the total interest paid on a home loan?

A: Our Mortgage Calculator shows total interest paid over the loan term. Enter loan amount, interest rate, and term (15 or 30 years). The results display total interest, total payment (principal + interest), and an amortization schedule showing how much interest vs. principal you pay each month. Interest is front-loaded—early payments are mostly interest. To reduce total interest, consider making extra principal payments or using our Mortgage Payoff Calculator to see how extra payments save interest.

Q: Is my currency converter accurate for international travel?

A: Our Currency Converter uses live exchange rates from reliable financial APIs, updated frequently throughout the day. It's accurate for planning and general reference, but actual rates at banks or exchange bureaus may differ slightly due to fees, spreads, and market fluctuations. For exact travel rates, check with your bank or currency exchange service. The converter supports 150+ currencies and shows historical trends to help you plan the best time to exchange.

Q: How do I estimate my pregnancy due date from LMP?

A: Add 280 days (40 weeks) to the first day of your Last Menstrual Period (LMP). Our Pregnancy Calculator does this automatically and also calculates from conception date or IVF transfer date. Enter your LMP date, and it shows your due date, current week of pregnancy, trimester, and key milestones. Note: Only 5% of babies are born exactly on the due date—most arrive between 38-41 weeks. Early ultrasounds (6-12 weeks) are the most accurate method for confirming due dates. For fertility planning, use our Ovulation Calculator to track your fertile window.

What are the best ways to reduce mortgage interest costs?

Lower your total mortgage interest with strategic payment strategies. Our Mortgage Calculator shows how extra payments reduce interest.
