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.

A useful sanity check: halving your average requires matching your entire original dollar exposure at half the price — averaging down gets expensive fast. The math is symmetric for averaging up into a winner, too.

Frequently asked questions

How is the new average price calculated?
Weighted by dollars: (existing coins × old average + new dollars) ÷ total coins after the buy. Buying below your average always pulls it down — the calculator shows exactly how far.
Is averaging down a good strategy?
It cuts your break-even, but it also concentrates more money in the same falling asset — 'catching a knife' when the thesis is broken, or a disciplined accumulation when it isn't. The calculator gives you the number; whether the thesis still holds is the real question.
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 with the DCA calculator.
Does averaging down help with taxes?
Each buy creates a new tax lot with its own basis and holding period. Depending on your country's cost-basis rules, that can matter a lot when you sell — see the crypto tax calculator.
