Why is $1000 today worth more than $1000 in the future?
$1000 today is worth more because it has greater purchasing power. Money available now can be invested to earn interest, growing to more than $1000 in the future. Conversely, due to inflation, $1000 in the future will likely buy fewer goods and services than $1000 today.
Conditions
- Assumes positive interest rates and/or inflation.
- Comparison is between the same nominal amount at two different times.
Reasoning, step by step
- Identify the two amounts: $1000 now and $1000 in the future.
- Explain the investment opportunity: $1000 now can earn returns.
- Explain the inflation effect: prices rise, reducing the buying power of future money.
- Conclude that the present amount is economically superior.
- Reference the visual aid: the red box around the present $1000 emphasizes its higher value.
Example
The speaker says: 'The thousand dollars in the present has more purchasing power than the thousand dollars in the future.' A red box is drawn around the left $1000 to highlight this point.
Common misconceptions
- Assuming that the face value determines the economic value.
