Key Concepts
- Dollar-Cost Averaging
- An investment strategy where a fixed amount is invested at regular intervals regardless of price. This approach reduces the impact of market volatility over time.
- Amortization
- The process of spreading loan payments over time so that each payment covers both interest and principal. Early payments are mostly interest, while later payments reduce more principal.
- Inflation Rate
- The rate at which the general price level of goods and services rises over time, reducing purchasing power. Central banks target low, stable inflation rates.
- Annual Percentage Rate (APR)
- The yearly interest rate charged on borrowed money or earned on an investment, expressed as a percentage. APR includes fees and additional costs associated with the transaction.
