About the High-Low Method

The high-low method is a simple technique used in cost accounting to separate fixed and variable costs by comparing the highest and lowest activity levels.

How It Works:

Identify the highest and lowest activity levels
Calculate the variable cost per unit: (Total Cost at High Activity – Total Cost at Low Activity) / (High Activity Units – Low Activity Units)
Determine fixed costs by subtracting total variable costs from total costs at either the high or low point
Form the cost equation: Total Cost = Fixed Cost + (Variable Cost per Unit × Activity Level)

Limitations:

Only uses two data points (high and low)
Assumes linearity in cost behavior
Can be inaccurate if high/low points are outliers

Introduction to the High-Low Method

Businesses need to understand their costs. The High-Low Method is a simple technique to analyze cost behavior. It helps separate fixed and variable costs.

A High-Low Method Calculator makes this process:
✓ Faster
✓ More accurate
✓ Easier to understand

This guide explains everything about this essential accounting tool.

Why the High-Low Method Matters

Simplifies Cost Analysis
Breaks down complex cost structures.
Helps with Budgeting
Predicts future costs accurately.
Improves Pricing Decisions
Shows true product costs.
Requires Minimal Data
Works with limited information.

How the High-Low Method Works

The method compares:

The highest activity level and its cost
The lowest activity level and its cost

This difference helps calculate:
✓ Variable cost per unit
✓ Total fixed costs

The High-Low Method Formula

Step 1: Find Variable Cost per Unit

Variable Cost = (High Cost - Low Cost) ÷ (High Activity - Low Activity)

Step 2: Calculate Fixed Costs

Fixed Cost = Total Cost - (Variable Cost × Activity Level)

Step-by-Step Calculation Example

Data:

Month	Units Produced	Total Cost
Jan	500	$12,000
Feb	800	$15,000
Mar	600	$13,000

Step 1: Identify High/Low Points

High: 800 units at $15,000
Low: 500 units at $12,000

Step 2: Calculate Variable Cost
= ($15,000 - $12,000) ÷ (800 - 500)
= $3,000 ÷ 300
= $10 per unit

Step 3: Find Fixed Costs
= $15,000 - ($10 × 800)
= $15,000 - $8,000
= $7,000 fixed costs

When to Use the High-Low Method

Best For:

✔ Quick cost estimates
✔ Businesses with simple cost structures
✔ Situations with limited historical data

Not Ideal For:

✗ Complex cost behaviors
✗ Seasonal businesses
✗ When data has outliers
