1. What is Change Calculation?

Change calculation determines the difference between a new value and an old value, showing either an increase or decrease in quantity. It's fundamental in analyzing growth, decline, or variation in any measurable quantity.

2. How Does the Calculator Work?

The calculator uses the simple change formula:

Where:

• Positive Result — Indicates an increase (New Value > Old Value)
• Negative Result — Indicates a decrease (New Value < Old Value)
• Zero Result — Indicates no change (New Value = Old Value)

3. Importance of Change Calculation

Applications: Change calculation is used in finance (profit/loss), science (experimental results), business (sales trends), health (weight changes), and many other fields to measure differences over time.

4. Using the Calculator

Instructions: Enter the old (initial) value and the new (current) value. The calculator will show the difference and indicate whether it's an increase or decrease.

5. Frequently Asked Questions (FAQ)

Q1: Can I calculate percentage change with this?
A: No, this calculates absolute change. For percentage change, you would need to divide the change by the old value and multiply by 100.

Q2: What if my change is negative?
A: A negative result means the new value is less than the old value (a decrease). The calculator displays the absolute value with "Decrease" label.

Q3: Can I use this for non-numerical values?
A: No, this calculator only works with numerical values where subtraction is meaningful.

Q4: How precise are the results?
A: Results are calculated to 2 decimal places for most accurate representation.

Q5: Can I compare more than two values?
A: This calculator compares two values at a time. For multiple comparisons, you would need to perform separate calculations.
