BMI (Body Mass Index) is a numerical value derived from dividing a person's weight by the square of their height. It is used as a screening tool for weight categories: underweight (below 18.5), normal (18.5–24.9), overweight (25–29.9), and obese (30+).

Question 2

TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns per day, combining your Basal Metabolic Rate (BMR) with your activity level. It is the foundation for weight loss (eat below TDEE) or weight gain (eat above TDEE) planning.

Question 3

What is compound interest?

Accepted Answer

Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. Often described as 'interest on interest,' it accelerates growth over time significantly compared to simple interest.

Question 4

Question 5

What is cap rate in real estate?

Accepted Answer

Cap rate (capitalization rate) is the ratio of a property's net operating income (NOI) to its current market value. It is used by real estate investors to evaluate and compare investment properties. A higher cap rate generally indicates higher return but also higher risk.

Question 6

What is FIRE investing?

Accepted Answer

FIRE (Financial Independence, Retire Early) is a financial movement focused on aggressive saving and investing — typically 50–70% of income — to achieve financial independence and retire well before the traditional retirement age of 65.

Question 7

What is the Rule of 72?

Accepted Answer

The Rule of 72 is a mental-math shortcut to estimate how long an investment takes to double. Divide 72 by the annual interest rate: at 6% growth, your money doubles in approximately 12 years (72 ÷ 6 = 12).

Question 8

What is the break-even point?

Accepted Answer

The break-even point is the level of sales at which total revenue exactly equals total costs, resulting in zero profit or loss. It is a critical metric for pricing strategy, launch planning, and business viability analysis.

Question 9

What is amortization?

Accepted Answer

Amortization is the process of spreading a loan into a series of fixed payments over time. Each payment covers the interest for that period plus a portion of the principal balance, gradually reducing the amount owed.

Question 10

What is a tax bracket?

Accepted Answer

A tax bracket is a range of income taxed at a specific rate in a progressive tax system. Importantly, only the income within each bracket is taxed at that bracket's rate — not your entire income. Moving into a higher bracket only affects the income above the threshold.
