# Average Cost & Invested Amount

> Learn how KoinX calculates amount invested and average cost for each asset so your portfolio view and crypto tax cost basis stay aligned across exchanges and wallets.

Your portfolio shows two columns that confuse most users: **Amount Invested** and **Average Cost**. If you have bought the same coin multiple times across different exchanges, you might wonder how that single number is calculated. Here is exactly how it works.

***

## What "Amount Invested" Means

**Amount Invested** is the total cost of acquiring the tokens you currently hold.

KoinX calculates this from your imported transactions, including buys, swaps where you received the asset, and other acquisition events in your history. If you later sell part of your holdings, the invested amount adjusts automatically to reflect only the cost of what you still own.

In simple terms, it answers: **"How much money went into the coins I currently hold?"**

***

## What "Average Cost" Means

**Average Cost** is the average price you paid per unit of that asset.

KoinX divides the total amount invested by the total quantity you currently hold. If you bought the same asset at different prices over time, this gives you a single blended acquisition price to compare against the current market value.

## Example

You bought Bitcoin twice:

* First purchase: 0.6 ETH at Rs. 2,20,000
* Second purchase: 0.183694 BTC at Rs. 28,000

Total investment: **Rs. 2,48,000** for 0.783694

Average Cost: **Rs. 3,17,000 per BTC**

This is the value shown as Average Cost in your portfolio.

***

## How the Wallet Filter Affects These Numbers

The values shown depend on which wallet is selected at the top of the dashboard.

**All Wallets selected:** KoinX combines transactions from all connected exchanges and wallets. The invested amount and average cost reflect your entire portfolio.

**Specific wallet selected:** The calculation uses only that wallet's transactions. This lets you analyse the performance of individual exchanges or wallets separately.

***

## Do Transfers Between My Wallets Change These Numbers?

No. Moving crypto between your own wallets does not change the invested amount or average cost. The original acquisition cost simply follows the asset to its new location.

***

## Why Your Average Cost Might Look Different Than Expected

Sometimes the average cost may not match what you remember paying. This usually happens for one of these reasons:

* You made multiple purchases at different prices over time
* Older transactions are included in the calculation alongside recent ones
* Fees were added to the acquisition cost of some transactions

Because KoinX uses your complete transaction history, the average reflects the true blended cost of your holdings, not just your most recent purchase.

***

## Why Portfolio Values May Differ from Your Exchange

Two common reasons for differences:

**Incomplete history:** If historical transactions are missing or not fully imported, the invested amount or average cost will appear incorrect. Syncing your full transaction history from when you first started trading is the fix.

**Price refresh timing:** KoinX is not a real-time portfolio tracker. Market prices refresh periodically, so values may differ slightly from what your exchange shows at any given moment.

## Frequently Asked Questions

<AccordionGroup>
  <Accordion title="Why is my Average Cost different from the price I remember buying at?">
    Average Cost is calculated across all acquisitions of that asset in your portfolio. If you bought the asset multiple times at different prices, the system calculates a blended average. Older purchases you may have forgotten are included in the calculation.
  </Accordion>

  <Accordion title="Does KoinX combine purchases from multiple exchanges?">
    Yes. When All Wallets is selected on the portfolio dashboard, KoinX calculates the average cost using transactions from all connected wallets and exchanges combined.
  </Accordion>

  <Accordion title="What happens if I select a specific exchange or wallet?">
    The invested amount and average cost are recalculated using only that wallet's transactions. This lets you analyse the performance of individual platforms separately from your overall portfolio.
  </Accordion>

  <Accordion title="Do transfers between my wallets change the invested amount?">
    No. Internal transfers move the asset from one wallet to another, but the original acquisition cost stays the same. The invested amount does not change as a result of transfers.
  </Accordion>

  <Accordion title="Why does my Average Cost look incorrect?">
    The most common reason is missing historical transactions. If older purchases were not imported, KoinX cannot calculate the correct acquisition cost. Syncing your full transaction history from when you first started trading usually resolves this.
  </Accordion>

  <Accordion title="Will editing a transaction update Average Cost?">
    Yes. If you edit a transaction, such as correcting the price, quantity, or fees, KoinX recalculates the invested amount and average cost automatically.
  </Accordion>
