High-Low Method for a Service Company Continental Railroad decided to use the high-low method and operating data from the past six months to estimate the fixed and variable components of transportation costs. The activity base used by Continental Railroad is a measure of railroad operating activity, termed "gross-ton miles," which is the total number of tons multiplied by the miles moved. Transportation Costs Gross-Ton Miles.

Step-by-step Solution
To apply the high-low method for estimating the fixed and variable components of transportation costs based on the provided data, you will need the following steps:
1. **Identify the Highest and Lowest Activity Levels**: Look at the gross-ton miles for the past six months and identify the highest and lowest values.
2. **Determine the Corresponding Transportation Costs**: Find the transportation costs that correspond to the highest and lowest gross-ton miles.
3. **Calculate the Variable Cost per Unit**: Use the formula:
\[
\text{Variable Cost per Unit} = \frac{\text{Cost at Highest Activity} - \text{Cost at Lowest Activity}}{\text{Gross-Ton Miles at Highest Activity} - \text{Gross-Ton Miles at Lowest Activity}}
\]
4. **Calculate Total Fixed Costs**: Once you have the variable cost per unit, you can use either the highest or lowest activity level to calculate the total fixed costs using the formula:
\[
\text{Total Fixed Costs} = \text{Total Cost} - (\text{Variable Cost per Unit} \times \text{Gross-Ton Miles})
\]
5. **Formulate the Cost Equation**: Finally, you can express the total transportation costs as a function of gross-ton miles:
\[
\text{Total Transportation Costs} = \text{Total Fixed Costs} + (\text{Variable Cost per Unit} \times \text{Gross-Ton Miles})
\]
### Example Calculation
Let's assume you have the following data for the past six months:
| Month | Gross-Ton Miles | Transportation Costs |
|-------|------------------|----------------------|
| 1 | 10,000 | $50,000 |
| 2 | 15,000 | $70,000 |
| 3 | 20,000 | $90,000 |
| 4 | 25,000 | $110,000 |
| 5 | 30,000 | $130,000 |
| 6 | 5,000 | $30,000 |
1. **Identify Highest and Lowest Activity Levels**:
- Highest: 30,000 gross-ton miles with $130,000 costs.
- Lowest: 5,000 gross-ton miles with $30,000 costs.
2. **Calculate Variable Cost per Unit**:
\[
\text{Variable Cost per Unit} = \frac{130,000 - 30,000}{30,000 - 5,000} = \frac{100,000}{25,000} = 4
\]
So, the variable cost per gross-ton mile is $4.
3. **Calculate Total Fixed Costs**:
Using the highest activity level:
\[
\text{Total Fixed Costs} = 130,000 - (4 \times 30,000) = 130,000 - 120,000 = 10,000
\]
4. **Formulate the Cost Equation**:
\[
\text{Total Transportation Costs} = 10,000 + (4 \times \text{Gross-Ton Miles})
\]
### Conclusion
Using the high-low method, you have estimated that the fixed costs are $10,000 and the variable cost is $4 per gross-ton mile. The total transportation cost can be expressed as:
\[
\text{Total Transportation Costs} = 10,000 + 4 \times \text{Gross-Ton Miles}
\]
You can now use this equation to estimate transportation costs for any level of gross-ton miles within the relevant range.
Quick Answer
To use the high-low method, identify the highest and lowest gross-ton miles and their corresponding costs. Calculate the variable cost per gross-ton mile and the fixed costs. The total transportation cost equation is then Total Transportation Costs = Fixed Costs + (Variable Cost per Unit × Gross-Ton Miles).
