Study Notes
Costs and break-even analysis involve understanding how businesses calculate and manage their expenses and revenues to determine profitability. Key concepts include revenue, fixed and variable costs, total costs, and the break-even point.
- Revenue — the total amount received from the sale of goods and services by a business. Example: Calculated as Price x Quantity.
- Fixed Costs — costs that do not vary with the level of output in the short run. Example: Rent and senior manager salaries.
- Variable Costs — costs that change as the level of output changes. Example: Wages and cost of raw materials.
- Total Costs — the sum of all fixed and variable costs of production. Example: Total Cost = Fixed Cost + Variable Cost.
- Profit or Loss — the difference between revenue and cost. Example: Profit is made when revenue exceeds costs.
- Break-even Level of Output — the quantity that must be produced and sold for total revenue to equal total cost. Example: At this point, neither a profit nor a loss is made.
