ROI —

ROI normalizes profit to capital deployed. Fee-aware ROI prevents overstating gains on high-turnover strategies.

ROI % = (Net profit ÷ Cost basis) × 100. Net profit = (Sell − Buy) × Units − Fees.

Buy $50,000, sell $65,000, 0.5 BTC, 0.2% fees → cost $25,000, gross gain $7,500, fees ≈ $115 → ROI ≈ 29.5%.

Buy $65,000, sell $60,000, 1 unit, no fees → ROI = −7.69%.

Is ROI the same as APY?

No. ROI is period return without annualizing. Use the compound / APY tools for time-based rates.

Should I include funding fees?

For futures, add estimated funding into the fee field or as a dollar adjustment for a truer net ROI.

Does this handle multiple lots?

Use average cost as buy price, or run each lot separately and sum profits.
