Mortgage Calculation
Formula: M = P [ r(1+r)^n ] / [ (1+r)^n – 1 ]
Where: M = Monthly payment, P = Principal loan amount, r = Monthly interest rate, n = Number of payments
Investment Calculation
Formula: FV = P(1 + r/n)^(nt)
Where: FV = Future value, P = Principal investment, r = Annual interest rate, n = Number of times interest is compounded per year, t = Number of years
BMI Calculation
Formula: BMI = weight(kg) / [height(m)]²
Categories: Underweight: < 18.5, Normal: 18.5-24.9, Overweight: 25-29.9, Obese: ≥ 30
Calorie Calculation
Formula (Mifflin-St Jeor):
Men: BMR = 10 × weight(kg) + 6.25 × height(cm) – 5 × age + 5
