Why Does Money Lose Value Over Time?
Money loses purchasing power over time primarily because of inflation, which erodes what a dollar can buy. Even without inflation, a dollar held idle today foregoes the interest or investment returns it could have earned. This opportunity cost means waiting to receive money always carries a hidden price.
How Is Time Value of Money Used in Financial Planning?
Financial planners use time value of money to calculate present value, future value, and loan amortization. It drives decisions like whether to take a lump-sum pension payout now or monthly payments for life, how much to save today to reach a retirement goal, and whether an investment's future cash flows justify its current price.
What Are Present Value and Future Value?
Present value is what a future sum is worth in today's dollars after discounting for time and interest. Future value is what a current sum grows to after earning returns over a period. Both calculations use an interest or discount rate to convert between the two, making them essential tools for comparing financial options across time.
Frequently asked questions
How does inflation relate to the time value of money?
Inflation is one of the main reasons money loses value over time. As prices rise, each dollar buys fewer goods. The time value of money accounts for this by discounting future sums back to their equivalent worth in today's purchasing power.
Is the time value of money relevant for everyday decisions?
Yes. Whether you're deciding to pay off debt early, lease versus buy a car, or invest a bonus, the time value of money helps you compare options involving different amounts at different points in time so you can make the financially optimal choice.
