What is Avg Buy Price?

The Avg Buy Price column is an optional field you can enable in the Holdings section of your portfolio detail screen. It shows you the average amount you’ve paid for a stock or crypto — including brokerage — spread across all the units you’ve ever bought.

It’s a quick way to see your “blended entry cost” per unit.

How it’s calculated

Navexa adds up the total value of all your buy trades, including brokerage, then divides that by the total number of units you’ve bought.

⚠️ Important:

  • Sell trades are not included in this calculation.

  • Sell brokerage is not included either.

  • It’s a standalone performance measure — it doesn’t affect your tax reporting or realised/unrealised calculations.


Example

Let’s say you bought shares in ABC Ltd:

  • Buy 50 units @ $10.00 each + $10 brokerage = $510

  • Buy 50 units @ $12.00 each + $10 brokerage = $610

Total cost = $1,120
Total units = 100

Avg Buy Price = $1,120 ÷ 100 = $11.20

So the Holdings section on your portfolio detail screen will show an average buy price of $11.20 for ABC.

If you later sell 30 shares, the Avg Buy Price won’t change. It will still display $11.20, because the column is designed to give you a stable benchmark for what you’ve paid on average — not to track parcels or adjust with sales.


Why this is useful

  • Keeps your performance view consistent.

  • Reflects your true average cost including brokerage.

  • Avoids confusion that can come from parcel-matching rules (FIFO/LIFO).

Some brokers recalculate the average price after every sale, but that depends on which parcels are “deemed” sold. Navexa instead keeps the Avg Buy Price simple and stable, so you always know your blended entry cost per unit.

Tip: You can toggle the Avg Buy Price column on or off in the Columns menu on your Holdings section.
