Formula Used in Acorns Investment Calculator
This tool is based on compound interest with monthly contributions.
1. Future Value of Initial Investment
FV = P × (1 + r)ⁿ
Where:
- P = Initial investment
- r = Monthly interest rate
- n = Number of months
2. Future Value of Monthly Contributions
Each monthly investment grows individually using compounding:
FV = PMT × [(1 + r)ⁿ - 1] ÷ r
Where:
- PMT = Monthly contribution
- r = Monthly interest rate
- n = Total months
3. Total Future Value
Total Value = Initial Investment Growth + Monthly Contributions Growth
4. Total Profit
Profit = Future Value − Total Invested
Key Concept: Compound Interest
Compound interest is the process where your money earns interest, and that interest also earns interest over time. This is why long-term investing is powerful.
