Calculators

Loan calculators use your principal amount, interest rate, and loan term to compute monthly payments, total interest, and total amount paid using amortization formulas.

BMI (Body Mass Index) = weight(kg) / height(m)². It's a screening tool for weight categories: <18.5 underweight, 18.5-24.9 normal, 25-29.9 overweight, ≥30 obese. It doesn't measure body fat directly.

Compound interest calculators show how money grows over time when interest is reinvested. They consider principal, interest rate, compounding frequency, and time period to project future values.

Health calculators include BMI, body fat percentage, ideal weight, calorie needs, pregnancy due date, ovulation tracking, and sleep cycle optimization. They provide estimates based on standard formulas.
