Understanding Time Value of Money vs Inflation

-

 


The time value of money (TVM) and inflation are two distinct concepts often discussed in finance and economics. While they may seem similar at first glance, they address fundamentally different aspects of how the value of money changes over time. Let’s explore these concepts in detail and clarify their differences using relatable illustrations.

The Concept of Time Value of Money

The time value of money simply states: “A naira (or dollar) today is worth more than a naira (or dollar) tomorrow.” This concept operates independently of inflation. Even if inflation rates remain constant or prices don’t change, a unit of money today is still more valuable because of the opportunity it provides to earn returns.

At its core, TVM is underpinned by the assumption of investment and return. If you receive a sum of money today, you can invest it and earn a return, increasing its value. If you receive the same sum tomorrow, you miss out on a day’s worth of potential returns. This opportunity cost is what drives the concept of TVM.

Imagine you’re given a magical seed that grows into a tree producing valuable fruits. Let’s assume:

  1. Once planted, the seed germinates into a mature tree and starts producing 100 fruits per day.
  2. The tree continues to produce 100 fruits daily forever (no decay or limit).
  3. You plant the seed as soon as it’s given to you.

Now, let’s say:

  • Frederick is given the seed on Day 1 and plants it immediately.
  • Jackson is given the seed on Day 2 and plants it immediately.

By the end of Day 10:

  • Frederick will have harvested 1,000 fruits (10 days × 100 fruits/day).
  • Jackson will have harvested 900 fruits (9 days × 100 fruits/day).

The difference in their total harvest is due to the fact that Frederick received and planted his seed earlier, allowing him to earn more returns.

The key takeaway here is that the earlier you receive a sum of money (or an asset like the seed), the sooner you can put it to work, earning returns that accumulate over time.

The Concept of Inflation

Now to the concept of inflation. Inflation focuses on the decline in the purchasing power of money over time. It’s how much of a particular item a unit or a sum of money can buy. It occurs due to rising prices of goods and services caused by external factors such as supply-demand imbalances, rise in production costs, or changes in economic policies.

To illustrate this, imagine you have ₦500 today. And today, ₦500 buys you one ice cream cone. A year from now, the same ice cream cone might cost ₦600 due to inflation.

Even though the ₦500 in your pocket hasn’t changed in nominal value, its purchasing power has decreased because prices have gone up. This is inflation. Inflation is when the same amount of money buys fewer goods over time.

Key Differences Between TVM and Inflation

Here’s how the two concepts differ:

Aspect

 

Time Value of Money (TVM)

Inflation

Focus

Lost opportunities and returns from delayed investment

Changes in the purchasing power of money due to rising prices

 

Example

Planting a seed earlier yields more fruits (returns).

Rising prices mean the same amount of money buys fewer fruits.

 

Driver

Investment and return on capital

Economic factors like demand, supply, and production costs

 

Effect

Encourages immediate investment to maximize returns

Highlights the erosion of money’s value over time

 

Dependency

Operates independently of inflation

Directly related to price changes in the economy

 

Are They Connected?

While time value of money and inflation are distinct, they can influence each other. Inflation can amplify the urgency of TVM. For instance, if inflation is high, money received today is even more valuable because it loses purchasing power more rapidly over time.

However, TVM is not solely dependent on inflation. Even in a world without inflation (where prices remain constant), TVM would still hold true because of the missed opportunity to earn returns on investments.

Conclusion

In summary, time value of money and inflation are related but distinct concepts. TVM focuses on the returns you could earn by investing money today, while inflation highlights how rising prices erode the purchasing power of money over time. Both remind us of the importance of managing money wisely—whether by investing early or safeguarding against inflation’s impact. In this 2025, invest wisely and timely to take advantage of TVM which will also help you to hedge against inflation.
