Study Notes - Business Mathematics for Level 100 Students, First Semester

Simple Interest

• Simple interest is calculated only on the principal amount.
• Formula: Simple Interest = (Principal × Rate × Time) / 100
• Example: $1,000 at 5% for 2 years = ($1,000 × 5 × 2) / 100 = $100

Compound Interest

• Compound interest is calculated on the principal and accumulated interest.
• Formula (compounded annually): Future Value = Principal × (1 + interest rate)^number of years
• Example: $1,000 at 5% for 2 years = $1,000 × (1 + 0.05)^2 = $1,102.50

Depreciation

• Depreciation is the decrease in the value of an asset over time.
• Linear depreciation: Annual depreciation = (Initial Cost - Salvage Value) / Useful Life
  • Example: Equipment costing $10,000 with a $2,000 salvage value over 5 years = ($10,000 - $2,000) / 5 = $1,600 per year.

Revenue, Cost, and Profit

• Total Revenue = Price × Quantity
• Total Cost = Sum of all costs
• Profit = Total Revenue - Total Cost
• Profit margin = (Profit / Revenue) ×100%

Markup and Margin

• Markup = (Cost × percentage markup)/100
• Selling price = Cost + Markup

Present Value

• Present value is the current worth of a future sum of money.
• Formula: Present Value = Future Value / (1 + interest rate)^number of years
• Example: If $100 is payable in 1 year at 5% interest, Present Value = $100 / (1 + 0.05) = $95.24

Bonds and Investments

• Bonds are debt instruments issued by companies or governments.
• Bond value = Face value × (1 + interest rate)^number of years
• Example: bonds with a face of $1000, at 5% interest for 3 years, is $1000 × (1 + 0.05)^3 = $1157.63

Loans and Payments

• Installments are equal payments made to repay a loan.
• Formulas for loan repayments are complex and usually involve present value calculations.

Miscellaneous

• Percentages are fundamental in business math.
  • Calculate percentages to express profit margins, discounts, and other business metrics.
  • Express relationships between quantities as percentages.

Important Formulas to Memorize

• Simple Interest
• Compound Interest
• Depreciation
• Revenue, Cost, Profit
• Present Value calculations
• Markup and Margin
• Bond valuation formulas (e.g., present value of bonds)
