📈 High-Low Method Calculator
Separate fixed and variable costs
Highest activity level (units, hours, etc.)
Total cost at high activity level
Lowest activity level (units, hours, etc.)
Total cost at low activity level
How to Use This Calculator
Enter High Activity Data
Input the highest activity level (units produced, hours worked, etc.) and the total cost at that activity level.
Enter Low Activity Data
Input the lowest activity level and the total cost at that activity level. This should be the minimum activity in your data set.
Calculate
Click calculate to see the variable cost per unit and fixed cost, which are separated using the high-low method.
Review Results
Use the cost formula to estimate total costs at any activity level. The formula shows fixed costs plus variable costs times activity.
Formula
Variable Cost per Unit:
Variable Cost = (High Cost - Low Cost) / (High Activity - Low Activity)
Fixed Cost:
Fixed Cost = High Cost - (Variable Cost × High Activity)
or
Fixed Cost = Low Cost - (Variable Cost × Low Activity)
Total Cost Formula:
Total Cost = Fixed Cost + (Variable Cost per Unit × Activity Level)
Example: Manufacturing Costs
High: 1,000 units @ $5,000 total cost | Low: 500 units @ $3,000 total cost
Variable Cost: ($5,000 - $3,000) / (1,000 - 500) = $2,000 / 500 = $4.00 per unit
Fixed Cost: $5,000 - ($4.00 × 1,000) = $1,000
Cost Formula: Total Cost = $1,000 + ($4.00 × Units)
At 750 units: $1,000 + ($4.00 × 750) = $4,000

Frequently Asked Questions
What is the high-low method?
The high-low method is a cost accounting technique that separates mixed costs into fixed and variable components using only the highest and lowest activity levels. It calculates the variable cost per unit as the slope between these two points, then determines fixed cost by subtracting variable costs from total cost at either point.
When should I use high-low method vs regression analysis?
Use high-low method for quick estimates, simple analyses, or when you have limited data. Use regression analysis when you need more accuracy, have many data points, or want to account for all observations. Regression analysis is more accurate but requires more data and calculation.
What if my high and low points are outliers?
If high or low points are outliers (unusual events), the high-low method may produce inaccurate results. Use representative high and low points that reflect normal operations. If outliers are present, consider using regression analysis instead.
Can I use more than two data points?
The high-low method uses only two points (highest and lowest). If you have more data points and want more accuracy, use regression analysis, which considers all data points and provides more reliable cost separation.
How accurate is the high-low method?
The high-low method provides reasonable estimates but is less accurate than regression analysis. Accuracy depends on how representative the high and low points are. If costs are relatively linear and the points are representative, results can be quite accurate. For more precision, use regression analysis.
What if my cost formula doesn't match actual costs?
If the formula doesn't match, costs may not be perfectly linear, the high/low points may not be representative, or there may be step costs or other complexities. Consider using regression analysis, checking for outliers, or analyzing cost behavior more carefully to identify non-linear patterns.
