Time Value of Money – Definition & Examples

Definition: The concept that money available today is worth more than the same amount in the future due to its earning potential.

Detailed Explanation

A dollar today can be invested to become more than a dollar tomorrow. This fundamental principle underlies all finance: comparing cash flows at different times requires discounting future values or compounding present values. Interest rates reflect the time value of money—compensation for waiting.

Real-World Example

$1,000 today invested at 5% becomes $1,050 in a year. Therefore, $1,000 today equals $1,050 next year. Lottery winners choosing lump sums over annuities consider time value—they can invest immediately.
