Understanding Horizontal Analysis
What is Horizontal Analysis?
Horizontal analysis (also known as trend analysis) is a financial statement analysis technique that compares historical data over different periods. It involves looking at the change in an account balance or line item from one period to the next (or over multiple periods) in both dollar amounts (absolute change) and percentages (percentage change).
Why Use Horizontal Analysis?
By highlighting changes over time, horizontal analysis helps identify trends, growth patterns, and areas requiring further investigation. It can reveal things like sales growth, increasing expenses, or changes in asset levels.
Formulas Used:
- Absolute Change = Current Period Value - Base Period Value
- Percentage Change = ((Absolute Change) / Base Period Value) * 100
(Percentage Change is not calculable if the Base Period Value is zero).
Horizontal Analysis Examples
Click on an example to see the calculation:
Example 1: Sales Growth
Scenario: Sales increased from $100,000 last year to $120,000 this year.
Inputs: Base Value = 100000, Current Value = 120000
Calculation:
- Absolute Change = 120000 - 100000 = $20,000
- Percentage Change = (20000 / 100000) * 100 = 20%
Result: Sales grew by $20,000, a 20% increase.
Example 2: Cost of Goods Sold (COGS) Increase
Scenario: COGS increased from $60,000 last year to $75,000 this year.
Inputs: Base Value = 60000, Current Value = 75000
Calculation:
- Absolute Change = 75000 - 60000 = $15,000
- Percentage Change = (15000 / 60000) * 100 = 25%
Result: COGS increased by $15,000, a 25% increase.
Example 3: Decrease in Operating Expenses
Scenario: Operating Expenses decreased from $30,000 last year to $25,000 this year.
Inputs: Base Value = 30000, Current Value = 25000
Calculation:
- Absolute Change = 25000 - 30000 = -$5,000
- Percentage Change = (-5000 / 30000) * 100 = -16.67%
Result: Operating Expenses decreased by $5,000, a 16.67% decrease.
Example 4: Significant Asset Increase
Scenario: Total Assets increased from $500,000 last year to $750,000 this year.
Inputs: Base Value = 500000, Current Value = 750000
Calculation:
- Absolute Change = 750000 - 500000 = $250,000
- Percentage Change = (250000 / 500000) * 100 = 50%
Result: Total Assets increased by $250,000, a 50% increase.
Example 5: Decrease in Long-Term Debt
Scenario: Long-Term Debt decreased from $200,000 last year to $150,000 this year.
Inputs: Base Value = 200000, Current Value = 150000
Calculation:
- Absolute Change = 150000 - 200000 = -$50,000
- Percentage Change = (-50000 / 200000) * 100 = -25%
Result: Long-Term Debt decreased by $50,000, a 25% decrease.
Example 6: Revenue from Zero
Scenario: Revenue was $0 last year and $50,000 this year (first year of significant sales).
Inputs: Base Value = 0, Current Value = 50000
Calculation:
- Absolute Change = 50000 - 0 = $50,000
- Percentage Change = Cannot be calculated from a base of zero.
Result: Revenue increased by $50,000. Percentage change is N/A.
Example 7: Expense drops to Zero
Scenario: An expense was $10,000 last year and $0 this year.
Inputs: Base Value = 10000, Current Value = 0
Calculation:
- Absolute Change = 0 - 10000 = -$10,000
- Percentage Change = (-10000 / 10000) * 100 = -100%
Result: The expense decreased by $10,000, a 100% decrease (eliminated).
Example 8: Small Increase on Large Base
Scenario: A large company's revenue increased from $1,000,000,000 last year to $1,050,000,000 this year.
Inputs: Base Value = 1000000000, Current Value = 1050000000
Calculation:
- Absolute Change = 1050000000 - 1000000000 = $50,000,000
- Percentage Change = (50000000 / 1000000000) * 100 = 5%
Result: Revenue increased by $50 million, a 5% increase.
Example 9: Large Decrease on Small Base
Scenario: Rent expense decreased from $2,000 per month to $1,000 per month.
Inputs: Base Value = 2000, Current Value = 1000
Calculation:
- Absolute Change = 1000 - 2000 = -$1,000
- Percentage Change = (-1000 / 2000) * 100 = -50%
Result: Rent expense decreased by $1,000, a 50% decrease.
Example 10: Change from Negative to Positive
Scenario: Net Income changed from a loss of $10,000 last year to a profit of $5,000 this year.
Inputs: Base Value = -10000, Current Value = 5000
Calculation:
- Absolute Change = 5000 - (-10000) = 5000 + 10000 = $15,000
- Percentage Change = (15000 / -10000) * 100 = -150%
Result: Net Income increased by $15,000. The percentage change is -150% (Interpretation of percentage change from a negative base requires care).
Note: Percentage changes from negative bases can be counter-intuitive and are often interpreted alongside the absolute change.
Frequently Asked Questions about Horizontal Analysis
1. What is the goal of horizontal analysis?
The goal is to identify trends in financial data over time by comparing line items from one period to the next, showing both dollar and percentage changes.
2. Which financial statements can use horizontal analysis?
Horizontal analysis can be applied to all financial statements, including the Income Statement, Balance Sheet, and Cash Flow Statement.
3. What is the "Base Period" and "Current Period"?
The Base Period is the earlier period you are using for comparison. The Current Period is the later period you are comparing against the base.
4. How is Absolute Change calculated?
Absolute Change is simply the difference between the Current Period Value and the Base Period Value (Current Value - Base Value).
5. How is Percentage Change calculated?
Percentage Change is calculated as ((Current Value - Base Value) / Base Value) * 100. It shows the relative change compared to the starting point.
6. What happens if the Base Period Value is zero?
If the Base Period Value is zero, the percentage change cannot be calculated (as you cannot divide by zero). The calculator will show the absolute change and indicate N/A for percentage change.
7. What does a negative percentage change mean?
A negative percentage change means the value decreased from the Base Period to the Current Period.
8. What does a positive percentage change mean?
A positive percentage change means the value increased from the Base Period to the Current Period.
9. Can I use horizontal analysis for more than two periods?
Yes, horizontal analysis is commonly used across multiple periods (e.g., 5 or 10 years) to identify longer-term trends. However, this specific calculator performs the analysis for just two periods at a time.
10. What are the limitations of horizontal analysis?
Limitations include: large percentage changes can be misleading when the base value is small, comparing data across periods with significant structural changes (e.g., acquisitions, divestitures) can distort trends, and it doesn't account for inflation unless data is adjusted.
