Basic Arithmetic
Arithmetic serves as the foundation for more complex mathematical operations in business. Here are some essential arithmetic formulas:
Addition and Subtraction
- Total Revenue (TR):
\[
TR = P \times Q
\]
Where \( P \) is the price per unit and \( Q \) is the quantity sold.
- Net Profit:
\[
\text{Net Profit} = \text{Total Revenue} - \text{Total Costs}
\]
Multiplication and Division
- Average Cost (AC):
\[
AC = \frac{\text{Total Costs}}{Q}
\]
- Market Share:
\[
\text{Market Share} = \frac{\text{Company's Sales}}{\text{Total Market Sales}} \times 100
\]
Percentages
Understanding percentages is crucial in business for tasks such as calculating profit margins, discounts, and growth rates. Here are some formulas related to percentages:
Percentage Calculation
- Finding a Percentage:
\[
\text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}}\right) \times 100
\]
- Percentage Increase:
\[
\text{Percentage Increase} = \left(\frac{\text{New Value} - \text{Old Value}}{\text{Old Value}}\right) \times 100
\]
- Percentage Decrease:
\[
\text{Percentage Decrease} = \left(\frac{\text{Old Value} - \text{New Value}}{\text{Old Value}}\right) \times 100
\]
Interest Calculations
Interest calculations are vital for evaluating investments, loans, and savings. The following formulas are commonly used in financial contexts:
Simple Interest
- Simple Interest:
\[
I = P \times r \times t
\]
Where \( I \) is the interest, \( P \) is the principal amount, \( r \) is the interest rate (as a decimal), and \( t \) is the time in years.
Compound Interest
- Compound Interest:
\[
A = P \left(1 + \frac{r}{n}\right)^{nt}
\]
Where \( A \) is the amount of money accumulated after n years, including interest, \( P \) is the principal, \( r \) is the annual interest rate (decimal), \( n \) is the number of times that interest is compounded per year, and \( t \) is the number of years.
Break-even Analysis
Break-even analysis is important for determining the point at which total revenues equal total costs, and no profit or loss occurs.
- Break-even Point (BEP):
\[
BEP = \frac{\text{Fixed Costs}}{\text{Price per Unit} - \text{Variable Cost per Unit}}
\]
This calculation helps businesses understand how many units they need to sell to cover their costs.
Cash Flow Analysis
Cash flow is vital for business sustainability. The following formulas help in assessing cash flow:
Net Cash Flow
- Net Cash Flow:
\[
\text{Net Cash Flow} = \text{Cash Inflows} - \text{Cash Outflows}
\]
Operating Cash Flow (OCF)
- Operating Cash Flow:
\[
OCF = \text{Net Income} + \text{Non-Cash Expenses} + \text{Changes in Working Capital}
\]
Return on Investment (ROI)
ROI is a key performance measure used to evaluate the efficiency of an investment.
- Return on Investment (ROI):
\[
ROI = \frac{\text{Net Profit}}{\text{Cost of Investment}} \times 100
\]
This formula provides insight into how well an investment is performing relative to its cost.
Inventory Management
Effective inventory management is critical for businesses that hold stock. The following formulas assist in optimizing inventory levels:
Inventory Turnover Ratio
- Inventory Turnover Ratio:
\[
\text{Inventory Turnover} = \frac{\text{Cost of Goods Sold}}{\text{Average Inventory}}
\]
This ratio indicates how many times a company has sold and replaced its inventory over a period.
Days Sales of Inventory (DSI)
- Days Sales of Inventory (DSI):
\[
DSI = \frac{365}{\text{Inventory Turnover}}
\]
This calculation helps businesses understand how long it takes to sell their inventory.
Financial Ratios
Financial ratios allow businesses to assess performance and make comparisons over time or against industry standards. Here are some important financial ratios:
Profitability Ratios
- Gross Profit Margin:
\[
\text{Gross Profit Margin} = \frac{\text{Gross Profit}}{\text{Total Revenue}} \times 100
\]
- Net Profit Margin:
\[
\text{Net Profit Margin} = \frac{\text{Net Profit}}{\text{Total Revenue}} \times 100
\]
Liquidity Ratios
- Current Ratio:
\[
\text{Current Ratio} = \frac{\text{Current Assets}}{\text{Current Liabilities}}
\]
- Quick Ratio:
\[
\text{Quick Ratio} = \frac{\text{Current Assets} - \text{Inventories}}{\text{Current Liabilities}}
\]
