Why Use the Average Down Calculator?
Manually calculating a blended average entry across multiple buys is tedious and error-prone. This calculator does it instantly — showing exactly how many additional shares or coins you need to buy at the current lower price to reach any target average cost. Plan your dollar-cost averaging strategy before committing capital.
Formula Used
New Average = (Shares1 × Price1 + Shares2 × Price2) ÷ (Shares1 + Shares2)Worked Example
You own 100 shares at $60 average (total cost $6,000). The stock drops to $45. You buy 133 more shares at $45 ($5,985). New average = (100×60 + 133×45) ÷ 233 = $11,985 ÷ 233 = $51.44 per share. You reduced your average by $8.56 and invested $11,985 total. The stock now needs to reach only $51.44 (not $60) to break even.

What Your Average Down Calculator Results Mean
New Average Cost
Your blended cost per share after both purchases. This is the price the stock must reach for you to break even on the combined position.
Total Units Held
The combined number of shares or coins in your position after the additional purchase.
Total Capital Invested
The total dollar amount you have put into this position across all purchases. Compare this to your available capital to ensure the full position is within your portfolio limits.
Average Cost Reduction %
How much you reduced your average cost per share as a percentage. A larger reduction means the new purchase was significantly lower than your original average.
Average Down Calculator — Frequently Asked Questions
Q.What does averaging down mean in investing?
Averaging down means buying more of an asset after its price has fallen to reduce your average cost per share. If you bought 100 shares at $50 ($5,000) and buy another 100 at $40 ($4,000), your new average is $45 (total $9,000 for 200 shares).
Q.Is averaging down a good strategy?
Averaging down works well for fundamentally sound assets in temporary downturns (quality stocks, major crypto). It is dangerous for assets in genuine decline or bankruptcy risk. Never average down on leveraged positions.
Q.What is DCA (Dollar Cost Averaging)?
DCA means investing a fixed dollar amount at regular intervals regardless of price. This is a form of systematic averaging that reduces the impact of volatility on your overall purchase price over time.
Q.How many shares do I need to buy to reach a target average?
Use the formula: Shares Needed = (Shares Held × (Current Avg − Target Avg)) ÷ (Target Avg − New Price). This calculator handles this math automatically — just enter your current position and target average price.
Q.Should you average down on forex or crypto losing positions?
Averaging down on leveraged forex positions is extremely dangerous and is the cause of many blown accounts — losses compound as price moves further against you. It works better on unleveraged stock or crypto positions in assets with strong fundamentals. Never average down on a leveraged position without recalculating your total risk exposure using this calculator first.
