Working out your average cost in ADA
Log each buy with its amount and price; the tool totals the invested capital, coins held and average cost, then values the position at a current price you provide.
Floating P&L is estimated at the 0.2197 USDT reference price by default — use the live-price button to refresh it.

The limit of averaging down in ADA
Buying lower does reduce your average cost, but it also increases position size and total risk. Average cost is an accounting number — it does not make a losing ADA position safe.
FAQ
How do I average the cost of several ADA buys?
Average cost = total invested ÷ coins held, where coins held is the sum of each amount ÷ price. Two 500 USDT buys at 0.1977 and 0.2417 USDT average about 0.2175 USDT, not the simple midpoint 0.2197 USDT.
How much am I down after scaling into ADA?
Floating P&L = coins held × current price − total invested. At the 0.2197 USDT reference price the two-leg example above shows about 10.1 USDT; below the average cost it turns negative.
