1. What is the High-Low Method?

The High-Low Method is a technique used in cost accounting to separate fixed and variable costs by comparing the highest and lowest levels of activity and their associated costs.

2. How Does the Calculator Work?

The calculator uses the High-Low Method formulas:

Where:

• \( VC \) — Variable cost per unit
• \( FC \) — Fixed cost
• \( high\_price\_cost \) — Total cost at highest activity level
• \( low\_price\_cost \) — Total cost at lowest activity level
• \( high\_units \) — Highest activity level in units
• \( low\_units \) — Lowest activity level in units

Explanation: The method calculates the variable cost per unit first, then uses that to determine the fixed cost component.

3. Importance of Cost Separation

Details: Separating fixed and variable costs helps in budgeting, forecasting, and decision-making. It's essential for break-even analysis and cost-volume-profit analysis.

4. Using the Calculator

Tips: Enter the total costs and activity levels at both high and low points. Ensure the high and low points represent normal operating conditions, not outliers.

5. Frequently Asked Questions (FAQ)

Q1: When should I use the High-Low Method?
A: It's best used when you need a quick estimate of fixed and variable costs and have limited data points.

Q2: What are the limitations of this method?
A: It only uses two data points, which may not represent the true cost behavior if those points are outliers.

Q3: How accurate is this method compared to regression analysis?
A: Regression analysis is more accurate as it uses all available data points, while high-low only uses two.

Q4: Can I use this for service businesses?
A: Yes, as long as you can identify appropriate activity measures and associated costs.

Q5: What if my high and low units are the same?
A: The calculator won't work as division by zero would occur. You need different activity levels.
