Quick Answer

Average Down Calculator: Weighted cost basis · breakeven move. Average Down Calculator uses standard finance formulas to compute accurate results instantly.

Average cost per share
17.5000
2,000 shares, total cost 35,000
Unrealized P&L-7000（-20.00%）
Breakeven move+25.00%
To reach 161,500 shares

Calculation steps

  1. 1Total cost = 20×1000 + 15×1000 = 35000.00
  2. 2Average cost = 35000.00 / 2000 shares = 17.5000
  3. 3At current price 14: P&L = (14 − 17.5000) × 2000 = -7000.00 (-20.00%)
  4. 4Breakeven needs +25.00% from current price
  5. 5To lower cost to 16: buy 1500 more shares at 14 (solve (cost + 14·x)/(qty + x) = 16)
Averaging down lowers your cost basis but increases concentration in a falling asset — the classic "catching a falling knife" risk. Before adding, ask: would you buy this position fresh today? The math: to halve your distance to breakeven you must roughly double your position at the current price. Never average down with leverage, and set a maximum position size in advance. Averaging UP into strength (pyramiding) carries the opposite risk-reward and is statistically kinder in trending markets.
