Average-Down Solver
Solve how much size to add at market to hit a target average entry.
ℹ️Adding size to a losing position increases total exposure. This always shows your new liquidation price alongside the answer.

Solving Backward From a Target, Not Forward From a Guess
Most average-down thinking works forward. "If I buy this much more at this price, where does my average land?" This solver works backward instead. You specify where you want your blended average entry to land, and it calculates exactly how much additional size, bought at the current market price, is required to get there. This framing tends to match how the decision actually gets made, since "I want my average at $59,000" is usually closer to the real thought process than iterating through trial position sizes.
The Math Behind the Solve
Given your current quantity and average entry, the current market price, and a target average, the solver rearranges the standard weighted average formula to isolate the one unknown, how many additional units to buy, algebraically. It only produces a valid answer when your target sits between the current market price and your existing average, in the direction consistent with averaging down. Buying more below your current average pulls the blended price down toward, but never past, the current market price itself.
Liquidation Price Before and After
Adding size to an existing leveraged position changes its liquidation price, and not always in an intuitive direction. Because your new blended average entry is lower (for a long) than your old average, but your total position notional and required margin have both grown, the tool calculates liquidation price before and after the add side by side, so the tradeoff, a better average entry in exchange for a different liquidation buffer, is visible before you commit the additional capital.
| What Improves | What The Add Costs You |
|---|---|
| Lower blended average entry | More total capital and margin at risk |
| Closer to breakeven on paper | A shifted, not necessarily safer, liquidation price |
Why the Momentum Warning Exists
Averaging down works from the assumption that the market will eventually move back in your favor. If the asset's RSI on the 1H timeframe is still overbought while you're averaging down a long, or still oversold while you're averaging down a short, that assumption is running ahead of the chart. Momentum hasn't reset yet, and there may be more room for price to move against the position before conditions actually favor a reversal. This tool checks live RSI data and surfaces a warning specifically in that situation, rather than assuming a bounce is close just because the average down plan wants one.
This is a planning estimate assuming your add executes exactly at the market price you entered. Real fills can differ due to slippage, especially for the larger order sizes this kind of rescue averaging often requires.
