Several buys, one honest average.

Bought in pieces? Put each buy in and get the average price, the break-even once fees on the way in and out are counted, and where the position stands now.

Your buys

Costs and now

Average price and break-even are not the same

The average entry is what you paid per unit: total spent divided by units bought. The break-even is higher, because fees were paid on every buy and will be paid again when you sell. The calculator includes both, so the break-even is the price at which selling everything gets back exactly what went in.

average entry = total spent ÷ total units break-even = (total spent + entry fees) ÷ (units × (1 − exit fee))

Worked example: $500 at 76,600 and $500 at 74,000 buys about 0.01328 coins for $1,000, an average of about 75,278. With 0.1% fees each way the break-even is about 75,428.

Spent, or units?

Choose "money spent" if you bought a fixed dollar amount each time, the usual way to dollar-cost average. Choose "units" if you bought a fixed number of shares or coins. Mixing the two in one calculation gives a wrong answer, so convert first.

Averaging down is a decision, not a plan B

Buying more of a falling position lowers the average and raises the exposure at the same time. Done to a plan, with the total size and the stop set in advance, it is a way to scale in. Done to escape a loss, it is how a small loss becomes a large one. Size the whole position first with the position size calculator.
