1. What is the High Low Calculation?

The High Low method is a technique used in cost accounting to separate fixed and variable components of mixed costs. It analyzes the highest and lowest activity levels to determine the variable cost per unit.

2. How Does the Calculator Work?

The calculator uses the High Low formula:

Where:

• \( high \) — Highest cost observed ($)
• \( low \) — Lowest cost observed ($)
• \( high\_activity \) — Activity level at highest cost (units)
• \( low\_activity \) — Activity level at lowest cost (units)
• \( VC \) — Variable cost per unit ($/unit)

Explanation: The equation calculates the variable cost per unit by comparing the difference in costs at different activity levels.

3. Importance of Variable Cost Calculation

Details: Understanding variable costs is essential for cost-volume-profit analysis, budgeting, and decision-making in business operations.

4. Using the Calculator

Tips: Enter the highest and lowest cost values in dollars, along with their corresponding activity levels in units. All values must be positive numbers, and activity levels must be different.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between fixed and variable costs?
A: Fixed costs remain constant regardless of activity level, while variable costs change in proportion to activity.

Q2: When should I use the high-low method?
A: It's most useful when you need a quick estimate of variable costs and have limited data points.

Q3: What are the limitations of this method?
A: It only uses two data points (highest and lowest) and may not account for outliers or non-linear cost behavior.

Q4: How accurate is the high-low method?
A: It provides a rough estimate. Regression analysis is more accurate but requires more data.

Q5: Can I calculate fixed costs from this?
A: Yes, once you have the variable cost per unit, fixed cost = Total cost - (Variable cost × Activity level).
