How the Ethereum ROI calculator works

This tool measures the return on your Ethereum position using buy price, sell price, total ETH amount, and fees. It starts with your initial cost basis, compares it with the final exit value, and then shows both simple ROI and annualized return. That makes it useful for checking a single ETH swing trade, comparing different exit prices, or reviewing long-term holding performance alongside tools in the full category index and the Math & Statistics Calculators page.

Example Ethereum ROI calculation

If you buy 2 ETH at $1,800 each, your starting investment is $3,600. If you later sell those 2 ETH at $3,650 each, your gross exit value becomes $7,300. After subtracting $75 in total fees, your net exit value is $7,225. That produces a net profit of $3,625 and an ROI of about 100.69%. If the hold lasted two years, the annualized return is lower than the simple ROI because the gain is spread across multiple years.
