Why should a crypto investor understand the concept of the time value of money?

Introduction: When $1000 Today Is Worth More Than Tomorrow

Suppose you have the opportunity to keep $1000 right now or wait a month to receive the same amount later. At first glance, there’s no difference. But from an economics and finance perspective, the difference is huge. This is the core idea of the concept called the time value of money – one of the most important concepts for any cryptocurrency investor.

The Main Idea: Why Today Is Better Than Tomorrow

The time value of money is based on the simple logic of opportunity cost. If you receive money today, you can start investing it immediately. During the waiting period, your money could be earning you a profit.

Imagine a real situation: your friend borrows $1000 from you. He offers to pay you back today if you come over, because tomorrow he’s flying on a long trip. Instead, he can return the same amount in 12 months.

The logic of the time value of money says: take the money now. In those 12 months, you could put it in a savings account with a 2% annual interest rate or invest it wisely to earn a profit. Additionally, inflation reduces purchasing power, so after 12 months, your $1000 will have less real value.

This raises a practical question: how much should your friend pay you after a year to make the waiting fair? At minimum, he should compensate for the potential earnings you missed out on.

How to Calculate Future Value of Money

To work with this concept, we need mathematical formulas. Let’s start with future value – the calculation of how much your money will be worth in the future if you invest it today.

Returning to the example with $1000 and a 2% annual return:

After one year: FV = 1000 × 1.02 = $1020

If your friend’s trip lasts two years:

FV = 1000 × 1.02² = $1040.40

Note that we apply compound interest – interest earned on interest.

The general formula looks like this:

FV = I × (1 + r)ⁿ

Where:

• I = initial investment amount
• r = annual interest rate
• n = number of years

This calculation helps you plan how much your investments will be worth in the future and make informed decisions about when to take your money.

Calculating Present Value: Estimating Future Sums

The reverse operation is calculating present value. Here, we try to understand how much a sum promised in the future is worth in today’s dollars.

For example, your friend says he will return in a year and give you $1030 instead of the initial $1000. Is this a good deal? Let’s calculate the present value at a 2% rate:

PV = 1030 ÷ 1.02 = $1009.80

Since the present value of $1009.80 is greater than what you gave ($1000), the deal is favorable – better to wait a year.

The formula for present value:

PV = FV ÷ (1 + r)ⁿ

The Impact of Compound Interest: Small Numbers, Big Results

Compound interest works like a snowball – the longer it rolls, the bigger it gets. In our examples, we considered annual compounding, but more frequent compounding options are also possible (quarterly, monthly).

Adjusting the formula for more frequent compounding:

FV = PV × (1 + r/t)^(n×t)

Where t = number of compounding periods per year.

For $1000 at 2% annual interest compounded quarterly:

FV = 1000 × (1 + 0.02/4)^(1×4) = $1020.15

An extra 15 cents may seem small, but over large sums and long periods, the difference becomes significant.

Inflation: When Interest Is Irrelevant

The problem is that high-interest rates can be almost meaningless if inflation is even higher. If you earn 2% annually but inflation is 3%, you’re actually losing purchasing power.

That’s why workers often negotiate salaries considering inflation. However, measuring inflation is difficult – different indices give different figures, and predicting future inflation is practically impossible. This means that in investment planning, we often have to make assumptions or rely on historical data.

How It Works in the Cryptocurrency World

The concept of the time value of money is especially important for crypto investors who constantly choose: hold coins now or lock them in for a yield?

Staking and fixed deposits: You can lock in 10 ETH now or earn 2% annually with a 6-month staking. Calculating the time value helps compare this offer with other opportunities in the ecosystem.

Buying BTC: Should you buy Bitcoin for $50 today or wait for your next paycheck and buy it for the same amount a month later? The general logic of the time value recommends the first option. However, in crypto, this is complicated by price volatility – BTC can rise or fall, which plays a bigger role than just the time value.

Choosing between coins: Get $100 in Bitcoin today or $110 in a new coin in a year? Even if the second option looks more profitable (10% profit), it depends on whether the first coin will generate enough income during that time.

Summary

Although the concept of the time value of money sounds complicated, you actually use it intuitively every day. Interest rates, investment returns, and inflation are all common phenomena in our economic life.

For large companies and professional investors, precise calculations of the time value of money are critical – even a fraction of a percent can mean millions. For crypto investors, it remains a practical tool that helps make informed decisions about how to allocate assets and maximize profits. Understanding this concept gives you a competitive edge in a market where time often makes all the difference.
