🔍 Subtopics

Simple Interest

Simple interest is calculated as a percentage of the principal amount, and it is paid only on the initial investment. The formula for simple interest is I = prt, where I is the interest earned, p is the principal amount, r is the rate of interest, and t is the time period. For example, if you invest $100 at 5% interest for 2 years, the interest earned would be I = 100 x 0.05 x 2 = $10.

Profit and Loss

Profit is the gain or benefit made from a transaction, while loss is the opposite, where you incur a financial loss. The profit formula is P = S - C, where P is the profit, S is the selling price, and C is the cost price. For instance, if you buy a book for $20 and sell it for $30, your profit would be P = 30 - 20 = $10.

Discounts

A discount is a reduction in the original price of an item. The formula to calculate the discount amount is D = (O x R) / 100, where D is the discount amount, O is the original price, and R is the rate of discount. For example, if you buy a shirt for $50 with a 20% discount, the discount amount would be D = (50 x 20) / 100 = $10.

Budgeting

A budget is a plan that outlines projected income and expenses over a specific period. The 50/30/20 rule suggests allocating 50% of your income towards necessities, 30% towards discretionary spending, and 20% towards saving and debt repayment. For instance, if you earn $500 per month, you would allocate $250 for necessities, $150 for discretionary spending, and $100 for saving and debt repayment.

Compound Interest

Compound interest is the interest earned on both the principal amount and any accrued interest. The formula to calculate compound interest is A = P x (1 + r/n)^(n ), where A is the accumulated value, P is the principal amount, r is the rate of interest, n is the number of times interest is compounded per year, and t is the time period. For example, if you invest $100 at 5% compound interest for 2 years, the accumulated value would be A = 100 x (1 + 0.05/12)^(12 ext{)} = $110.25.

Financial Statements

A balance sheet shows a company's financial position at a specific point in time, listing assets, liabilities, and equity. The income statement presents a company's revenues and expenses over a specific period. The cash flow statement shows the movement of cash into and out of a business.

Investment Strategies

A diversified investment portfolio involves spreading investments across different asset classes to minimize risk. Dollar-cost averaging involves investing a fixed amount of money at regular intervals, regardless of market conditions. Value investing focuses on buying undervalued assets with the potential for long-term growth.

Credit and Loans

A credit score is a three-digit number that represents an individual's creditworthiness. The most widely used credit scoring model is FICO, which considers payment history, credit utilization, length of credit history, and new credit accounts. A loan is a financial agreement where one party lends money to another, with the borrower agreeing to repay the loan with interest.

Taxes and Inflation

Inflation is the rate at which prices for goods and services are rising. The formula to calculate inflation is I = ((P2 - P1) / P1) x 100, where I is the inflation rate, P1 is the initial price, and P2 is the new price. Taxes are fees imposed by governments on income, sales, or property. The tax rate is the percentage of income that must be paid as taxes.

Financial Planning

Financial planning involves setting financial goals, assessing current financial situation, and creating a plan to achieve those goals. It includes budgeting, saving, investing, and managing debt. A financial plan should consider factors such as income, expenses, assets, liabilities, and credit score.

Risk Management

Risk management involves identifying potential risks and developing strategies to mitigate or manage them. This can include diversifying investments, maintaining an emergency fund, and having insurance coverage for unexpected events such as job loss or medical emergencies.

Financial Tools and Resources

Financial tools and resources include budgeting apps, financial calculators, and investment platforms. These tools can help individuals track their spending, create a budget, and make informed investment decisions. They can also provide access to financial experts and educational resources.
