Understanding Deflation
Deflation is a decrease in the general price level of goods and services, typically measured by the inflation rate falling below 0%. While mild deflation might seem beneficial as consumers can buy more for less, severe or prolonged deflation can be harmful to an economy:
- Increased Real Value of Debt: Borrowers find it harder to repay loans as the real value of money increases.
- Delayed Spending: Consumers and businesses may postpone purchases, expecting lower prices in the future.
- Reduced Business Revenue: Lower prices lead to lower sales and profits.
- Wage Cuts: Businesses may reduce wages to match falling prices, leading to economic contraction.

Example Calculation
Suppose a product cost $100 in 2018 and $80 in 2023 (5 years later):
- Initial Price: $100
- Final Price: $80
- Time Period: 5 years
- Deflation Rate: -20%
- Annualized Deflation Rate: -3.87%
This means the product's price decreased by 20% over 5 years, averaging a 3.87% decline per year.
