📚 Understanding Percentage Decreases
Simple vs. Compound
Simple decrease shows total change, while compound shows consistent annual rate that would produce the same result over time.
Negative Growth
A negative growth rate means the value is decreasing over time rather than increasing.
Time Matters
The same absolute decrease represents different rates when spread over different time periods.
Context is Key
A 10% decrease might be catastrophic for stocks but normal for seasonal products.
Compare Benchmarks
Compare your decrease rate to industry standards to assess performance.
Seasonal Patterns
Some decreases are normal seasonal variations rather than long-term trends.
Note: This calculator provides estimates based on the inputs provided. For financial decisions, consult with a professional. Compound decrease rates assume consistent annual decreases.
