- •Long-term portfolio planning
The calculator demonstrates how small consistent gains can compound into large portfolio growth over time.
Formulas
Basic Compound Interest Formula
A = P (1 + r/n)^(nt)
Compound Growth With Contributions
FV = P(1+r)^t + PMT × (((1+r)^t - 1) / r)
Net Return Formula
Net Return = Gross Return - Trading Fees
ROI Formula
ROI% = ((Final Balance - Total Deposits) / Total Deposits) × 100
How The Calculation Works
Step 1 — Define Starting Capital
The calculator begins with the initial account balance.
Example: Initial Balance = 1000 USDT
Step 2 — Apply Compound Growth
Profits are continuously added back into the portfolio.
Example: Monthly Return = 5% (New balance grows every cycle)
Step 3 — Add Monthly Deposits
Optional recurring deposits accelerate growth.
Example: Monthly Deposit = 100 USDT
Step 4 — Subtract Estimated Fees
Trading costs can reduce long-term portfolio growth.
Example: Fee Reduction = 0.5%
Step 5 — Calculate Final Portfolio Value
The calculator outputs the projected future balance.
Example: Final Balance = 3100+ USDT

Why Compounding Matters
Compound growth is one of the most powerful concepts in finance and trading.
Instead of withdrawing profits, compounding reinvests gains back into the account, increasing future position sizes and accelerating growth over time.
This is especially important for:
- •Automated trading bots
- •Swing trading systems
- •Long-term investing
- •Passive crypto strategies
- •Portfolio management
Even relatively small monthly returns can generate significant long-term growth when compounded consistently.
Common Use Cases
Trading Bot Growth Simulation
Estimate how automated trading strategies may scale over time.
Long-Term Investing
Project future crypto portfolio value using recurring contributions.
Passive Income Planning
Analyze how compounding can build sustainable long-term capital.
Strategy Performance Analysis

Important Notes
- •Compound growth is not guaranteed
- •Real market conditions vary
- •Trading losses reduce compounding efficiency
- •Higher returns usually involve higher risk
- •Fees and slippage impact long-term results
- •Unrealistic ROI expectations can be dangerous
