Investment Analysis
Example Compound Growth Calculation
20-Year Investment with Monthly Deposits
Initial Balance: $1,000
Annual Interest Rate: 8%
Term: 20 years
Compounding: Monthly (12 times per year)
Additional Deposits: $50 per month
Compound Growth Calculation
Initial Balance Growth: $1,000 × (1 + 0.08/12)240 = $4,927
Additional Deposits Total: $50 × 240 = $12,000
Deposits Future Value: ~$29,647 (with compound interest)
Total Final Balance: $4,927 + $29,647 = $34,574
Total Principal: $1,000 + $12,000 = $13,000
Total Compound Growth: $34,574 - $13,000 = $21,574

Understanding Compound Growth
What is Compound Growth?
Compound growth occurs when your investment earnings are reinvested to generate their own earnings. This creates a snowball effect where your money grows exponentially over time, not just linearly.
The Power of Compounding
- •Earlier you start, more powerful the effect
- •Consistent contributions amplify growth
- •Higher rates and frequent compounding help
- •Time is the most critical factor
Compound Growth Formula
FV = PV × (1 + r/m)m×t
CG = FV - PV
- FV: Future Value (final balance)
- PV: Present Value (initial balance)
- r: Annual interest rate (as decimal)
- m: Compounding frequency per year
- t: Time in years
- CG: Compound Growth
Einstein reportedly said: "Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn't, pays it."
Factors Affecting Compound Growth
Initial Amount
Larger starting amounts provide more base for compounding
Interest Rate
Higher rates accelerate compound growth significantly
Time Period
Longer periods unleash the true power of compounding
Frequency
More frequent compounding increases effective returns
