About the Average Down Calculator
Averaging down means adding to a losing position at a lower price to reduce your blended average entry. Enter each buy as a price and a quantity, and this calculator sums your total cost and quantity to give a single average entry. Add the current market price to see your live unrealized profit/loss, current value, and ROI — so you know exactly what a new buy does to your cost basis and break-even before you place it.
Frequently Asked Questions
How do I calculate my average entry after averaging down?
Add each buy as a price and quantity. Your blended average entry is total cost (sum of price × quantity) divided by total quantity. This calculator updates it instantly as you add or edit entries.
What new price do I need to break even after averaging down?
Your break-even is your blended average entry price shown in the results. Once the market trades back to that average, your unrealized P&L is zero; above it you are in profit.
Is averaging down a good idea?
Averaging down lowers your average cost but increases position size and risk if the price keeps falling. Use this tool to see exactly how each added buy changes your average entry and unrealized P&L before committing more capital.
