Formulas and Examples

The simulator uses a consistent and realistic two-sided fee model, meaning fees are applied when you buy and when you sell.

Core Formulas

Buy Fee           = Investment × (Fee% / 100)
Effective Invest  = Investment − Buy Fee
Coins             = Effective Investment / Buy Price
Gross Value       = Coins × Sell Price
Sell Fee          = Gross Value × (Fee% / 100)
Final Value       = Gross Value − Sell Fee

Profit & ROI

Profit / Loss = Final Value − Investment
ROI (%)       = (Profit / Loss / Investment) × 100

Example

Let’s say:

• Investment = $1,000
• Buy Price = $100
• Sell Price = $150
• Fee = 1%

Step-by-step:

• Buy Fee = $10
• Coins = 9.9
• Final Value = $1,470.15
• Profit = $470.15
• ROI = 47.02%

This shows how fees impact real returns—something many calculators ignore.

DCA Formula

Total Coins    = Σ (Monthly Investment / Price_i)
Average Cost   = Total Invested / Total Coins

DCA naturally lowers your average cost because you buy more when prices are low and less when prices are high.

Example 

You invest $100 every month for 3 months:

✅  Results

• Total Invested = $300
• Total Coins = 3.5
• Average Cost = 300 / 3.5 = $85.71

Break-even Formula

You must sell at $102.03 just to recover your $1,000 investment.

Break-even Price = Investment / (Coins × (1 − Fee% / 100))

This is the exact price required to recover your full investment after fees.

Example 

Let’s assume:

• Investment = $1,000
• Buy Price = $100
• Fee = 1%

Step-by-step:

• Buy Fee = $1,000 × 1% = $10
• Effective Investment = $990
• Coins Bought = 990 / 100 = 9.9 coins

Now calculate break-even price:

• Break-even Price = 1000 / (9.9 × 0.99) ≈ $102.03

✅ Result

You must sell at $102.03 just to recover your $1,000 investment.
