Formula Used in Acorns Calculator
The calculator is based on compound interest with monthly contributions.
1. Compound Interest Formula (Initial Investment)
FV = P × (1 + r)^n
Where:
- FV = Future Value
- P = Initial investment
- r = Monthly interest rate
- n = Number of months
2. Monthly Contribution Growth Formula
Each monthly investment grows over time:
FV = M × [((1 + r)^n - 1) / r]
Where:
- M = Monthly contribution
- r = Monthly interest rate
- n = Total months
3. Total Future Value
Total Value = Initial Investment Growth + Monthly Contribution Growth
Example Calculation
Let’s understand with a real example:
- Initial Investment = $2,000
- Monthly Contribution = $300
- Time Period = 10 years
- Annual Return = 7%
Step-by-step outcome:
- Total Invested = $38,000
- Estimated Future Value = $55,500 (approx.)
- Profit Earned = $17,500
This shows how consistent investing can significantly increase wealth over time.
Investment Growth Table Example
| Years | Total Invested ($) | Estimated Value ($) | Profit ($) |
|---|---|---|---|
| 5 | 20,000 | 24,800 | 4,800 |
| 10 | 38,000 | 55,500 | 17,500 |
| 15 | 56,000 | 102,300 | 46,300 |
| 20 | 74,000 | 180,000 | 106,000 |
| 25 | 92,000 | 300,000 | 208,000 |
How Compound Interest Works in This Tool
Compound interest is the process where your money earns returns, and those returns also start earning returns.
Key idea:
The longer you invest, the faster your money grows.
For example:
- In early years, growth is slow
- In later years, growth becomes exponential
This is why long-term investing is powerful.
