Time value is the financial principle that money available today is worth more than the same amount received in the future. This occurs because present money can be invested to earn returns, whether through interest, dividends, or capital appreciation. Understanding time value is critical for angel investors evaluating startup opportunities and determining fair valuations.
How It Works
The mechanics are straightforward: if you have $100,000 today, you can invest it at an expected return rate—say 8% annually. In one year, that investment grows to $108,000. Conversely, if someone promises you $108,000 in one year, it's worth approximately $100,000 in today's dollars (discounting back at 8%). This relationship between present value, future value, and discount rates forms the foundation of investment analysis.
Two key calculations emerge from this principle: future value (what money today will be worth later) and present value (what future money is worth today). Investors use these calculations to compare investment opportunities on equal terms and make rational capital allocation decisions.
Why It Matters for Investors
Time value directly impacts how you evaluate startup investments. When an angel investor evaluates a company projecting $5 million in revenue five years out, you must discount that future value back to today's dollars using an appropriate discount rate. A discount rate reflects both the time value of money and the specific risk of that investment.
This principle also explains why exit multiples matter. An investor seeking a 5x return over five years is accounting for time value—you're not just getting your money back, you're being compensated for the time your capital was at risk and the opportunity cost of deploying it elsewhere.
Example
Suppose you're considering two investment options: Fund A promises to return $2 million in three years, while Fund B will return $2 million in five years. Without understanding time value, these seem equivalent. But with a 15% discount rate (typical for early-stage investments), Fund A's present value is approximately $1.3 million, while Fund B's is roughly $992,000. Fund A is clearly superior because you receive your returns sooner, allowing reinvestment opportunities.
This same logic applies to startup valuations. A company worth $10 million based on future earnings projections should be valued lower today if those earnings won't materialize for several years.
Key Takeaways
- Money today is always worth more than money in the future due to earning potential and opportunity cost
- Use present value calculations to fairly compare investments occurring at different time horizons
- Your expected return rate (discount rate) reflects both time value and investment-specific risk
- Earlier exits and faster revenue growth directly increase investment returns by reducing the time your capital is deployed
