How the Brokerage Account Calculator Works
The brokerage account calculator estimates your investment growth based on several key factors:
- Initial investment amount
- Annual return percentage
- Investment period in years
- Compounding frequency (annually, monthly, etc.)
- Estimated fees and taxes
Formula Used
The calculator uses the compound interest formula:
Future Value = P × (1 + r/n)^(nt)
Where:
- P = Principal amount (initial investment)
- r = Annual interest rate (return percentage)
- n = Number of times interest is compounded per year
- t = Time the money is invested for in years
The calculator then applies estimated fees and taxes to provide a more realistic projection of your account value.

| 1 | $10,000.00 | $700.00 | $10,700.00 |
| 2 | $10,700.00 | $749.00 | $11,449.00 |
| 3 | $11,449.00 | $801.43 | $12,250.43 |
| ... | ... | ... | ... |
| 10 | $20,124.75 | $1,408.73 | $21,533.48 |
