Average Entry Price Calculator Crypto (DCA) & Break-even

Crypto Average Entry Price Calculator

Built a position in several fills, or dollar-cost averaged into a coin? Enter up to 10 fills (price and size, in dollars or coins) to get your average entry price, the total size and the break-even price once the fees on the way in and out are paid, for a long or a short.

A BTC long filled at $84,766.30, $81,375.60 and $77,985.00 averages $81,281.39; break-even after 0.05% fees each way is $81,362.72. With BTC at a live price of $84,766.30 that is $125.56.

Estimate: These are estimates. Exchanges use tiered maintenance margin (bigger positions need more), liquidate on the mark price rather than the last trade, and handle fees and cross margin their own way. Check your exchange's position screen before you trade.

Worked example

BTC long, the numbers above

Each fill's size in BTC is its dollar amount ÷ its price. Your 3 fills add up to 0.0369088 BTC for $3,000.00.
Average entry = total cost ÷ total size = $3,000.00 ÷ 0.0369088 = $81,281.39. Bigger fills pull the average towards their price.
Fees: 0.05% of each fill = $1.50 so far. Closing costs 0.05% again, so break-even = average × (1 + fee) ÷ (1 − fee) = $81,362.72, 0.10% above the average.
At the current price of $84,766.30 (+4.29% from the average) the long is at $125.56 after fees on the way in and out.

The formula

Average entry = (Price₁ × Size₁ + Price₂ × Size₂ + …) ÷ (Size₁ + Size₂ + …)

Size in coins = Size in USD ÷ Price · Fees paid = fee rate × Σ (Price × Size)

Break-even (long) = Average × (1 + fee) ÷ (1 − fee) · (short) = Average × (1 − fee) ÷ (1 + fee)

The average entry is weighted by size, so a big fill moves it more than a small one. Dollar-cost averaging a fixed amount buys more coins when the price is low, which pulls the average below the simple mean of your prices. Break-even adds the fee you paid on every fill and the one you will pay to close. Funding is not included.

Crypto Average Entry Price Calculator FAQ

How is the average entry price calculated?

Add up what every fill cost (price × size), then divide by the total size. It is a weighted average: a fill twice as big counts twice as much. With sizes in dollars, each fill's coins are its dollar amount ÷ its price, so cheaper fills buy more coins.

What is the break-even price?

The exit price where the trade makes exactly zero after fees. You paid the fee on every fill and pay it again to close, so for a long it sits a little above the average entry and for a short a little below.

Does leverage change the average entry?

No. Leverage changes the margin, not the prices you filled at. It does change the liquidation price: check it with the liquidation price calculator at your new average.

Is funding included?

No. A perp position also pays or receives funding while it is open, which moves your real break-even over time.
