Concept and Formulas of Commercial Maths
The concept of Commercial Mathematics revolves around applying mathematical techniques to address real-world problems that come up in commerce and finance. It combines fundamental mathematical principles with practical business applications to make it easier financial decision-making and economic analysis. Here are the core aspects of Commercial Maths.
Here’s a detailed overview of key concepts in Commercial Mathematics, including relevant formulas:
- Basic Arithmetic Operations:
Addition, Subtraction, Multiplication, and Division: Fundamental operations used for various business calculations such as determining totals, differences, and ratios.
Formulas:
- Addition: a+b
- Subtraction: a−b
- Multiplication: a×b
- Division: a/b
Example:
- Addition: If a business earns $500 from one project and $300 from another, the total earnings are 500+300=800 dollars.
- Multiplication: If a product costs $20 and 50 units are sold, total revenue is 20×50=100020 \times 50 = 100020×50=1000 dollars.
- Percentages:
A percentage represents a fraction of 100.
Percentage Calculation: To find the percentage of a value, use:
| Percentage = (Part/Whole) × 100 |
Example:
- Percentage Calculation: If a business has $2000 in sales and $500 in costs, the cost percentage is: (500/2000)×100=25%
Percentage Increase/Decrease:
| Percentage Increase = (New Value−Old Value/Old Value) × 100 |
| Percentage Increase = (New Value−Old Value/Old Value) × 100 |
- Profit and Loss:
Measures the financial gain or loss in business transactions.
Profit:
| Profit = Selling Price−Cost Price |
Loss:
| Loss = Cost Price−Selling Price |
Profit Percentage:
| Profit Percentage = (Profit/Cost Price)×100 |
Loss Percentage:
| Loss Percentage = (LossCost Price)×100 |
Example:
- Profit Calculation: If the cost price of a product is $150 and the selling price is $200, the profit is:
Profit = 200−150=50 dollars
- Profit Percentage: (50150)×100 = 33.33%
- Interest Calculations:
Interest is the cost of borrowing money or the return on investment.
Simple Interest:
| I = P×R×T |
where I is the interest, P is the principal amount, R is the rate of interest per period, and T is the time period.
Compound Interest:
| A = P(1+R/n)nT |
where A is the amount, P is the principal, R is the annual interest rate, n is the number of times interest is compounded per year, and T is the time in years.
Compound Interest (CI):
| CI = A−P |
Example:
- Simple Interest: If $1000 is invested at an annual interest rate of 5% for 3 years, the simple interest is: I = 1000×0.05×3 = 150 dollars
- Compound Interest: For the same principal, rate, and time with interest compounded annually:
A = 1000(1+0.051)1×3 = 1000×1.157625 = 1157.63 dollars
CI = 1157.63 – 1000 = 157.63 dollars
- Discounts:
A reduction in the usual price.
Percentage Discount:
| Discount Amount = Marked Price × (Discount Percentage/100) |
Selling Price After Discount:
| Selling Price = Marked Price−Discount Amount |
Effective Discount:
| Effective Discount = (Discount Amount / (Marked Price−Discount Amount))×100 |
Example:
Percentage Discount: If a product’s marked price is $100 and the discount offered is 20%, the discount amount is:
Discount Amount=100×(20/100)=20 dollars
Selling Price: Selling Price=100−20=80 dollars
- Taxes:
Compulsory financial charges imposed by the government.
Sales Tax:
| Sales Tax Amount = Selling Price × (Sales Tax Rate/100) |
Total Price Including Tax:
| Total Price = Selling Price + Sales Tax Amount |
Example:
Sales Tax Calculation: If the selling price of a product is $200 and the sales tax rate is 10%, the sales tax amount is:
Sales Tax Amount = 200×(10/100) = 20 dollars
Total Price: Total Price = 200+20 = 220 dollars
- Annuities:
A series of equal payments made at regular intervals.
Future Value of Annuity (FV):
| FV = (P×(1+r)n−1)/r |
where P is the annuity payment, r is the interest rate per period, and n is the number of periods.
Present Value of Annuity (PV):
| PV = (P×1−(1+r)-n)/r |
Example:
Future Value of Annuity: If $1000 is deposited annually at an interest rate of 5% for 3 years, the future value is:
FV = 1000×((1+0.05)3−1)/0.05
=1000×(1.157625−1)/0.05
=1000×3.1525 = 3152.50 dollars
- Depreciation:
The reduction in the value of an asset over time.
Straight-Line Depreciation:
| Annual Depreciation = (Cost of Asset−Salvage Value)/Useful Life |
Declining Balance Depreciation:
| Depreciation Expense = Book Value at Beginning of Year × Depreciation Rate |
Example:
Straight-Line Depreciation: If an asset costs $10,000, has a salvage value of $2000, and a useful life of 4 years, the annual depreciation is:
Annual Depreciation = (10000−2000)/4 = 2000 dollars
- Financial Ratios and Analysis:
Metrics used to evaluate a company’s financial performance.
Liquidity Ratios:
- Current Ratio:
| Current Ratio = Current Assets/Current Liabilities |
- Quick Ratio:
| Quick Ratio = (Current Assets−Inventory)/Current Liabilities |
Profitability Ratios:
- Gross Profit Margin:
| Gross Profit Margin = (Gross Profit/Sales)×100 |
- Net Profit Margin:
| Net Profit Margin = (Net Profit/Sales)×100 |
Example:
Current Ratio: If a company has current assets of $50,000 and current liabilities of $25,000, the current ratio is:
50000/25000 = 2
Gross Profit Margin: If sales are $100,000 and gross profit is $40,000, the gross profit margin is:
(40000/100000)×100 = 40%
Solvency Ratios:
- Debt to Equity Ratio:
| Debt to Equity Ratio = Total Liabilities/Shareholders’ Equity |
- Risk Management:
The process of identifying, assessing, and controlling financial risks.
Probability:
| Probability = Number of Favorable Outcomes/Total Number of Outcomes |
Expected Value:
| Expected Value = ∑(Value of Outcome×Probability of Outcome) |
Example:
Probability: If there are 5 favorable outcomes out of 20 possible outcomes, the probability is:
5/20 = 0.25 or 25%
