The compounded annual return, its month-by-month texture, and the two months that did the most work in each direction.
This page lists every year of Ethereum (ETH)'s history on Coinfuty as a single compounded annual return, next to its month-by-month texture. Ethereum's yearly rows compress its cycle history into single figures: back-to-back triple-digit years into 2021, the deep 2022 unwind, and the choppier ETF-era years since. The month strip beside each total shows how much of every year came from just one or two months — a recurring ETH pattern.
Each year compounds its twelve monthly returns from UTC daily closes, with the current year riding as a year-to-date row until it closes. ETH's data starts at its perpetual listing in November 2019. That window frames Ethereum's modern era — DeFi summer 2020, the 2021 double-peak, the 2022 unwind and the ETF-era regime after it.
Ethereum is down 15.6% year-to-date in 2026, compounding 9 completed months plus October to date, through the daily close of 10 October 2026 (UTC). The YTD chip stays provisional until the year closes.
Ethereum returned −11.0% over calendar 2025, from the 2024 close to the 2025 close. Its best month was July at +48.8% and its worst February at −32.2%.
Ethereum's completed calendar years on Coinfuty: 2015 −67.0%, 2016 +753.6%, 2017 +9,396%, 2018 −82.4%, 2019 −3.2%, 2020 +470.2%, 2021 +399.3%, 2022 −67.5%, 2023 +90.9%, 2024 +46.1%, 2025 −11.0%. 6 of 11 years closed positive, and 2026 is down 15.6% so far.
The median completed year for Ethereum is +46.1%, across 11 full years on record. The median is used instead of the mean because Ethereum's yearly results are extreme in both directions, and one outlier year would distort a simple average.
Ethereum's best completed year on record is 2017 at +9,396% and its worst is 2018 at −82.4%. Both are compounded from monthly returns, so they match what a position held through the entire year would have earned.
Every completed year's compounded ETH return is listed here and the readout above the grid quotes the median across them. Because Ethereum's yearly results are extreme in both directions, that median is a more honest summary than a simple average.
ETH's history here begins at its first daily perpetual-futures candle on Binance in November 2019, and each row needs a calendar year — so the table is exactly as deep as its perpetual history and grows as years close.
Because returns compound. A +10% month followed by a −10% month leaves −1%, not 0%. The yearly totals multiply the monthly factors together, which is what a held position would have earned.
