What is Future Value?
Future Value is how much your money will be worth at some point in the future, assuming it grows at a certain rate.
Think of it like planting a seed: You start with something small today, and over time it grows into something much bigger. Future Value tells you how big that tree will be.
Future Value calculations assume your money stays invested and all earnings are reinvested. Taking money out will change the result.
The Future Value Formula
Where:
- FV = Future Value (what you'll have)
- PV = Present Value (what you start with)
- r = Interest rate per period
- n = Number of periods
With Monthly Contributions:
Example
You invest $10,000 today at 7% annual return for 20 years:
- Without contributions: $10,000 → $38,697
- With $200/month: $10,000 + contributions → $142,000
The monthly contributions make a HUGE difference!
The Power of Time
$10,000 invested at 7% annual return:
| Years | Future Value | Interest Earned |
|---|---|---|
| 5 | $14,026 | $4,026 |
| 10 | $19,672 | $9,672 |
| 20 | $38,697 | $28,697 |
| 30 | $76,123 | $66,123 |
| 40 | $149,745 | $139,745 |
Starting early is the biggest advantage. $10,000 invested for 40 years earns almost 4x more than the same amount invested for 20 years.
Why Monthly Contributions Matter
$500/month invested at 7% for different periods:
| Years | You Put In | You Get Back | Free Money |
|---|---|---|---|
| 10 | $60,000 | $86,000 | $26,000 |
| 20 | $120,000 | $260,000 | $140,000 |
| 30 | $180,000 | $567,000 | $387,000 |
After 30 years, you've more than tripled your money!
Realistic Return Expectations
| Investment Type | Expected Return | Risk Level |
|---|---|---|
| Savings Account | 4-5% | Very Low |
| Bonds | 5-6% | Low |
| Balanced Portfolio | 6-7% | Medium |
| Stock Index Funds | 7-10% | Medium-High |
| Individual Stocks | Varies | High |
Higher returns usually mean higher risk. A 7% return is a reasonable long-term assumption for a diversified stock portfolio.

That daily latte could become a house down payment!
🧒 Start Early vs Start Late
Meet Alex and Jordan:
- Alex starts at 25, invests $200/month until 65 = $525,000
- Jordan starts at 35, invests $400/month until 65 = $400,000
Alex invested half as much but ends up with more money. That's the power of starting early!
