Why Timing Matters in Money

When thinking about money, you must ask two simple questions:

• How much?
• When?

It’s not just about the amount—it’s also about the timing. Money received today is worth more than the same amount received in the future.

Examples to Understand Time Value

Let’s break it down with a few simple questions:

• Would you rather receive $100 today or $100 one year from now? Most people choose today.
• What about $100 today or $101 next year? Still, many choose today.
• Now try $100 today vs. $110 next year. That extra $10 might make waiting worth it.

This tells us there’s a point where future money becomes valuable enough to wait for. If you’re indifferent between $100 now and $105 in a year, that 5% becomes your personal time value of money.

Inflation and Opportunity Cost

Why is money now worth more?

1. Inflation – Over time, prices rise, reducing purchasing power.
2. Opportunity Cost – Money today can be invested to earn returns.

The Math Behind Time Value of Money

Let’s do the math to understand how future and present values are related.

Future Value (FV):

Future Value = Present Value × (1 + Rate)^Years

Example:

$100 × 1.05 = $105 (in 1 year)

$105 × 1.05 = $110.25 (in 2 years)

Or directly: $100 × (1.05)^2 = $110.25

Present Value (PV):

Present Value = Future Value / (1 + Rate)^Years

To reverse the example:

$110.25 ÷ 1.05 = $105 (1 year back)

$105 ÷ 1.05 = $100 (2 years back)

Why TVM Is So Important

The Time Value of Money is foundational in personal and corporate finance. It powers decisions like:

• Investment appraisals using Net Present Value (NPV)
• Evaluating returns with Internal Rate of Return (IRR)
• Understanding loans, interest, and compounding

It’s the compass for making sound financial decisions over time.
