Clear mathematical explanations and worked calculations for online calculators.
CAGR Formula
FinanceCompound Annual Growth Rate (CAGR) is the geometric progression ratio that provides a constant rate of return over a specified time period. It is one of the best tools for comparing investment returns across different assets (like mutual funds vs gold vs FDs) over multi-year horizons because it smooths out volatility.
Calorie Needs Formula
HealthThis formula extends the Mifflin-St Jeor TDEE calculation one step further by applying a calorie surplus or deficit based on a specific weight goal, producing a single daily calorie target. It relies on the widely-used approximation that roughly 500 kcal of daily deficit or surplus corresponds to about 0.5 kg (1 lb) of body weight change per week.
Capital Gains Tax Calculation Formula
FinanceCapital Gains Tax is levied on net profit realized from selling capital assets like shares, equity funds, debt funds, gold, or real estate. Holding period determines classification into Short-Term (STCG) or Long-Term (LTCG) gains.
Carpet Area Formula
Real EstateCarpet Area, Built-Up Area, and Super Built-Up Area are the three RERA-defined area measures used across Indian real estate listings. Carpet Area is the actual usable floor space within the walls of a unit, while Super Built-Up Area — the figure most often quoted in pricing — adds walls, balconies, and a proportionate share of shared building amenities. This formula lets a buyer work backward from the quoted saleable area to the real usable space.
Celsius to Fahrenheit Formula
Unit ConvertersTo convert a temperature reading from Celsius (°C) to Fahrenheit (°F), multiply the Celsius value by 9/5 (or 1.8) and then add 32 to account for the freezing point baseline difference.
Centimeters to Inches Formula
Unit ConvertersBy international agreement, 1 inch is defined as exactly 2.54 centimeters. To convert centimeters to inches, divide the length in centimeters by 2.54.
CGPA to Percentage Formula
Mathematics & EducationThe CGPA to Percentage conversion formula calculates equivalent percentage marks from CGPA scores for CBSE (CGPA × 9.5), AICTE/VTU ((CGPA - 0.75) × 10), and Mumbai University.
Compound Interest Formula
FinanceCompound interest is the interest calculated on the initial principal, which also includes all of the accumulated interest from previous periods. Unlike simple interest, compound interest allows your money to grow exponentially because you earn interest on interest.
Compound Savings Formula
FinanceThe Compound Savings Formula computes the total future wealth accumulated from an initial starting deposit (P) plus regular periodic additions (PMT) earning compound interest over time (t).
Concrete Volume Calculation Formula
Real Estate & ConstructionConcrete volume formula computes cubic yards or cubic meters of wet ready-mix concrete required to pour rectangular slabs, footings, steps, or columns.
