Money Basics · Lesson 3 of 14
Match Your Investments to Your Timeline
When you need the money and how much loss you can absorb should shape what you invest in. Inflation and compounding explain why time matters.
In this lesson
- Define time horizon
- Tell risk tolerance apart from risk capacity
- Explain inflation and compounding, including how losses compound
Your time horizon is how long you can leave money invested before you need it. Money for a purchase next year has a different job from money for retirement decades away.
More time can help you live through market swings, but it doesn’t promise a profit. Prices can stay down for years.
Two kinds of risk comfort
Risk tolerance
- How much uncertainty you can emotionally handle
- A feeling: “Can I sleep with this?”
Risk capacity
- How much loss your finances can actually absorb
- A fact: “Can I still pay my bills if this drops?”
Risk tolerance and risk capacity don’t always match. A person may enjoy taking risks while having very little financial room for a loss. When they disagree, it’s safer to plan around the lower one.
Inflation and compounding
Inflation means prices generally rise over time, so the same dollars may buy less. If prices rise a hypothetical 3% in a year, something that cost $100 costs $103, so $100 in cash buys about 3% less. Compounding means returns can begin earning returns of their own. Investment returns fluctuate, and losses compound too.
Example Consider this example
If $1,000 grows by a hypothetical 5% in one year, it becomes $1,050. Another 5% makes it $1,102.50. A 20% loss would instead turn $1,000 into $800, and getting back to $1,000 from there takes a 25% gain. This illustration ignores fees and taxes and isn’t a forecast.
Tip
Gains and losses aren’t symmetrical. A 10% drawdown needs about an 11% gain to recover, and a 50% drop needs 100%. That’s why protecting money you can’t replace comes first.
Check your understanding
3 questions. Answer each one, then open “Show answer” to compare.
Question 1 of 3 $1,000 gains a hypothetical 10% in year one and loses 10% in year two. What is it worth after year two, ignoring fees and taxes?
dollarsShow answer
Answer: 990 dollars.
$1,000 × 1.10 = $1,100, then $1,100 × 0.90 = $990. A gain and a loss of the same percentage don’t cancel out, because the loss applies to a larger balance.
Show answer
Answer: B. High risk tolerance but low risk capacity
Jordan is comfortable with risk emotionally (tolerance) but has little financial room for a loss (capacity). Planning around the lower of the two protects the rent.
Show answer
Answer: False.
More time can help you ride out swings, but it doesn’t promise a profit. Some investments stay down for years or never recover.
Key takeaways
- Match each pot of money to when you’ll need it.
- Risk tolerance is a feeling; risk capacity is what your finances can absorb.
- Inflation erodes buying power, and compounding works on losses as well as gains.
Key terms
