Quick answer

Averaging down on ETH means buying more at a lower price to cut your average entry. Your new average equals total spent divided by total ETH held. This tool returns the new average, your break-even price, and the percentage move needed to get back to profit after the added buy.

How this is calculated

Your new average price is the dollar-weighted mean of both buys: new avg = (coins × old avg + new $) ÷ (coins + new $ ÷ buy price). Break-even equals that new average, and "% to break even" measures the climb from your buy price to it.

The form pre-fills a real Ethereum scenario — a $1,000 position from the Aug 2025 all-time-high month, averaged down at our latest snapshot price — because that's the situation this calculator usually gets opened in. A sanity check worth keeping: halving your average requires matching your entire original dollar exposure at half the price. Averaging down gets expensive fast.

Averaging down a $1,000 ETH top-buy, by add size

Added at today's price New average Rise still needed Total at risk
Nothing (hold) $4,956.78 156.4% $1,000.00
$500.00 $3,258.29 68.5% $1,500
$1,000 $2,781.71 43.9% $2,000
$2,500 $2,341.38 21.1% $3,500

$1,000 bought at the Aug 2025 intra-month high ($4,956.78), added to at the 2026-07-21 snapshot price ($1,933.34) — no fees. Every added dollar lowers the required recovery and raises the total exposed. Not a projection.

Frequently asked questions

How is my new average ETH price calculated?
Weighted by dollars: (existing ETH × old average + new dollars) ÷ total coins after the buy. Buying below your average always pulls it down — the calculator shows exactly how far, and the break-even price it implies.
If I bought $1,000 of ETH at the all-time high, what does averaging down today do?
Using the Aug 2025 intra-month high (about $4,956.78) and our 2026-07-21 snapshot price of $1,933.34: without adding, the position needs 156.4% to break even. Adding another $1,000 at today's price cuts the required climb to about 43.9% — at the cost of doubling the money at risk in the same coin.
Is averaging down on Ethereum a good idea?
The calculator answers the arithmetic — the new break-even — not the judgment. Averaging down cuts the required recovery but concentrates more capital in the same falling asset. Whether the original ETH thesis still holds is the real question, and no calculator answers it.
What's the difference between averaging down and DCA?
Averaging down is a reactive, one-off buy triggered by a drop; dollar-cost averaging is a fixed schedule that ignores price. Backtest the scheduled version on real history with the ETH DCA calculator.
Does averaging down affect my taxes?
Each buy creates a new tax lot with its own cost basis and holding period. Depending on your country's rules, that can change what you owe when you sell — see the crypto tax calculator.
