Average entry price calculator

When you buy (or sell) the same pair in several parts, this works out your average price. Enter each price and lot size to get the average weighted by lot size.

You getThe average price weighted by lot size, and the total lots

What to enter, and the terms used

You enterThe pair (for the number of decimals) and the price and lot size of each entry (2 to 6 entries)

Enter at least 2 entries to see the result. Empty rows are skipped. Work out buys and sells separately
Your entries stay on this device only and will be here next time. You can use . or , for decimals. If a number has separators, we show how it was read below the field.

Example: enter this, get this

  1. Pair: EUR/USD
  2. Entry 1: 0.2 lots at 1.0800
  3. Entry 2: 0.1 lots at 1.0850

(1.0800 × 0.2 + 1.0850 × 0.1) ÷ (0.2 + 0.1) = 0.32450 ÷ 0.3 = 1.08167, with 0.3 lots in total. It is not the simple average of the two prices (1.08250), because the lot sizes differ.

The example numbers only show how the calculation works. They are not recommendations. Replace them with your own account’s numbers, or use “Clear inputs”.

Where do I find these numbers?

Price
The Price column for each position in the Trade tab (the MT5 Toolbox or the MT4 Terminal). Leave out anything you have closed
Lots
The volume (lot size) column on the same tab

The mobile app and platforms other than MT4/MT5 may use different names or places. If you cannot find a number, check your broker’s help pages.

How it works

  1. Average price = sum of (price × lots) ÷ total lots
  2. Example: 0.2 lots at 1.0800 and 0.1 lots at 1.0850 gives (0.21600 + 0.10850) ÷ 0.3 = 1.08167
  3. The result is rounded to the number of decimals used for the pair you choose.

Formula, a worked example and common mistakes

The formula

Average price = (price 1 × lots 1 + price 2 × lots 2 + …) ÷ total lots

It is an average weighted by lot size. When the lot sizes differ, it is not the same as adding the prices and dividing by the number of entries.

A worked example by hand: EUR/USD bought in two parts
  1. Entry 1: 1.0800 for 0.2 lots → 1.0800 × 0.2 = 0.21600
  2. Entry 2: 1.0850 for 0.1 lots → 1.0850 × 0.1 = 0.10850
  3. Average price = (0.21600 + 0.10850) ÷ (0.2 + 0.1) = 0.32450 ÷ 0.3 = 1.081666… (shown as 1.08167)
The numbers only show how the calculation works. They are not recommendations, and the rates are examples.
3 common mistakes
  1. Adding the prices and dividing by the number of entriesThat only works when every entry has the same lot size. With different sizes, weight each price by its lots.
  2. Including the part you already closedAfter a partial close, use only what you still hold. The same goes when you compare with an average price shown in your platform.
  3. Mixing buys and sellsIf you hold both buys and sells (hedging), work out each side separately. Mixing them gives a meaningless number.

FAQ

Is this a tool for averaging down?

No. It only works out the average price of entries you split up. It does not suggest adding to a position. Splitting an entry still means a bigger total size, so the same price move changes your P&L by more.

Does it work for sells?

Yes. The math is the same for sells. If you hold both buys and sells, work out each side separately.

Why is it a little different from my platform?

Rounding and how partly closed positions are handled can differ. If your platform shows an average price, enter only what you still hold when you compare.

Do you log why you split your entries?
