Cost Accounting Fixed Vs Variable Costs
Variable costs are the engine of the business, while fixed costs are the chassis carrying that engine; one increases as you accelerate, while the other makes its weight felt even when you are fully stopped.
Cost accounting dissects the anatomy of profitability by splitting expenses into two opposing poles based on production volume. Fixed costs (rent, executive salaries, insurance) are rigid obligations that must be paid even if the company produces absolutely nothing. Variable costs (raw materials, commissions, packaging), however, emerge solely when production lines run and sales are made. As business volume grows, the fixed cost per unit decreases; this is known as economies of scale. In a zero-to-one structure, keeping fixed burdens low and variable structures flexible is the most fundamental operational defense mechanism that prevents the ship from sinking during crises.
