Break-Even Calculator

Average price and break-even for scaled-in positions.

Calculator

The break-even calculator finds the volume-weighted average entry price of a position you built in up to three parts. When you add to a trade at different prices, this average is your break-even: the price at which the whole position is flat, before trading costs. Enter each price and its lot size to get it.

How to Use the Break-Even Calculator

  1. Choose the Instrument. It sets how many decimal places the result shows.
  2. Enter Price 1 and Lots 1 for your first entry.
  3. If you scaled in, add Price 2 and Lots 2, and Price 3 and Lots 3. Leave unused rows empty.
  4. Press Calculate to see the average entry, the total size and the number of legs counted.

Average Entry Price Formula

Average entry = (P1 × L1 + P2 × L2 + P3 × L3) ÷ (L1 + L2 + L3)

  • P1, P2 and P3 are the prices of each entry.
  • L1, L2 and L3 are the lot sizes of each entry. Bigger entries pull the average towards their price.
  • A row is skipped if its price is blank or its lot size is blank or zero.

Worked Example

You buy EUR/USD in three steps: 1 lot at 1.10000, 0.5 lots at 1.09500 and 0.5 lots at 1.09000.

  • Price × lots: 1.10000 × 1 = 1.10000, 1.09500 × 0.5 = 0.54750, and 1.09000 × 0.5 = 0.54500
  • Sum: 1.10000 + 0.54750 + 0.54500 = 2.19250
  • Total size: 1 + 0.5 + 0.5 = 2.00 lots
  • Average entry: 2.19250 ÷ 2 = 1.09625

The whole 2-lot position is flat at 1.09625, which is 37.5 pips below your first entry.

Adding Costs and Checking Profit

The average is a raw price. For a buy, your true break-even sits a little higher once you add the spread and any commission; for a sell, it sits a little lower. Adding to a losing trade lowers your average but also raises your size, so plan the total risk before the first entry. To see the profit on the whole position at a target, enter the average price and total lots into the profit calculator.

FAQ

Does this include costs?

No. It is the raw volume-weighted average price. Add the spread, commission and any swap to find your true break-even. For a buy, move the level up by those costs in pips; for a sell, move it down.

Does it work for sell positions?

Yes. The average entry is worked out the same way for a buy or a sell. A buy is in profit once price rises above the average, and a sell once price falls below it. Enter legs from one direction only, as the calculator treats them all alike.

Can I add more than three entries?

The form takes three legs. For more, calculate the first three, then enter the result as Price 1 with the total size as Lots 1, and add your next two entries in the other rows. The average comes out the same.

What is a volume-weighted average price?

It is an average where each price counts in proportion to its size. Buying 2 lots at 1.1000 and 1 lot at 1.1030 gives an average of 1.1010, closer to the larger entry, rather than the simple midpoint of 1.1015.

What does the instrument setting change?

Only the number of decimal places shown: five for most pairs, three for yen pairs and two for gold, silver and bitcoin. The average itself depends only on the prices and lot sizes you enter.
