Diskonttovirhe

Diskonttovirhe, often translated as discount error or discounting error, is a term used in economics and finance to describe a mistake in calculating the present value of future cash flows. This typically occurs when an incorrect discount rate is applied. The discount rate reflects the time value of money and the risk associated with receiving a future payment. A higher discount rate implies a greater risk or opportunity cost, leading to a lower present value, while a lower discount rate results in a higher present value.

The impact of a diskonttovirhe can be significant. For example, in investment appraisal, using an inappropriately low discount rate can lead to overestimating the profitability of a project, potentially resulting in poor investment decisions. Conversely, an excessively high discount rate might cause a project to be rejected when it would have been profitable. In financial markets, miscalculating the present value of bonds or other financial instruments due to an incorrect discount rate can lead to mispricing and trading errors.

Common causes of diskonttovirhe include using a discount rate that does not accurately reflect the project's risk profile, failing to adjust the discount rate for inflation, or simply making a mathematical error in the discounting formula. Correctly determining and applying the appropriate discount rate is crucial for accurate financial analysis and sound decision-making in both personal finance and corporate finance.
