Compounded price return for every calendar month on record. Read down a column for seasonality, across a row for the year's rhythm.
Ethereum's return calendar tells a different story from Bitcoin's, even though the two markets move together most of the time. ETH amplifies both directions: its strong months tend to stack during risk-on stretches when the ETH/BTC ratio is climbing, and its weak months cluster when capital rotates back into Bitcoin. Reading the monthly grid next to Bitcoin's makes those rotation phases easy to spot — the columns where ETH's cells run deeper in both directions.
The history here starts from Ethereum's first daily perpetual-futures candle in late 2019, which conveniently frames the modern era: DeFi summer 2020, the 2021 double-peak, the 2022 unwind and the ETF-era regime that followed. Use the Yearly tab to see how much of each year's result came from just one or two months — a recurring pattern in ETH's history.
Ethereum is down 6.6% in October 2026 so far, measured from the last daily close of the previous month to the daily close of 10 October 2026 (UTC). This is a month-to-date figure: it keeps moving with every daily close until October ends, and the cell stays italic in the grid until then.
Ethereum returned +8.8% in September 2026, its most recent completed calendar month, from that month's last daily close against the close of the month before. The median September return on record is −9.1%, so last month came in above its historical norm.
Ethereum is down 15.6% year-to-date in 2026, compounding 9 completed months plus October to date. A year-to-date return is what a position bought at the 2025 close would be worth at the 10 October 2026 close, not the sum of the monthly cells. For comparison, 2025 closed at −11.0%.
Ethereum returned −11.0% over calendar 2025, compounding its monthly returns from the 2024 close to the 2025 close. Its best month was July at +48.8%, its worst was February at −32.2%, and 3 of 12 months closed positive.
Among the 9 completed months of 2026, Ethereum's strongest was August at +32.5% and its weakest was June at −21.7%. 5 of the 9 closed positive. October is still in progress and is not counted until it closes.
Across 11 completed Octobers on record (2015–2025), the median October return for Ethereum is +2.3%. The best October was 2021 at +43.0%, the worst was 2016 at −16.8%, and 7 of 11 closed positive. The current October is excluded until it closes.
Ethereum is down 6.6% quarter-to-date in Q4 2026, compounding October so far. The previous quarter, Q3 2026, closed at +70.8%. Quarterly figures multiply the monthly returns together, so they match a position held through the whole quarter.
By median return across 134 completed months on record, January has been Ethereum's strongest calendar month at +32.5% and September its weakest at −9.1%. Medians shift as each new year is added, so treat this as a description of the past, not a forecast.
The Median row under the monthly grid computes it live — the calendar month with the highest median ETH return across all recorded years is its highest cell. It shifts as new years land, so the live grid is the authoritative answer rather than any fixed month.
Each coin's history begins at its first daily perpetual-futures candle. Ethereum's USDT perpetual started trading on Binance in November 2019, a couple of months after Bitcoin's, so its grid has slightly fewer rows.
Loosely. The broad risk-on and risk-off months often match, but ETH regularly diverges when the ETH/BTC ratio trends — some of its best months arrived while Bitcoin was flat. The medians on each page are computed independently from each coin's own history.
