The purchase price is the tax value attributed to an asset at the time of purchase, or after a tax-relevant event.

In other words, it is the cost recognised for tax purposes, which will be used to calculate any capital gains or losses at the time of sale.

In the software, the purchase price is determined automatically on the basis of the transactions imported (purchases, sales, conversions, etc.) and according to the applicable tax method.

The purchase price is essential because:

•it is used to calculate capital gains (when you sell at a higher price)

• it is used to calculate capital losses (when you sell at a lower price)

• it determines the actual taxable amount

• it affects the calculation of the total tax cost of the portfolio

Example:

If you sell an asset for £1,500 and its cost price is £1,000, the taxable capital gain will be £500, not the entire amount received.

It is important to distinguish between how much you have invested and the recognised tax value.

The amount invested simply represents the money you have paid in (e.g. by bank transfer or card).

The purchase price, on the other hand, is a tax figure that is recalculated over time based on the transactions carried out.

They do not coincide because:

1️⃣ Tax-relevant transactions change the carrying value.

Every time you carry out a transaction that generates a capital gain or loss (e.g. a sale or a crypto-to-crypto conversion), the system determines a new tax value for the assets purchased or remaining in your portfolio.

2️⃣ The calculation follows tax rules, not bank movements

The software does not rely solely on how much money you have transferred, but applies the tax rules for calculating taxes based on your country of tax residence.

3️⃣ The portfolio updates over time

If you sell part of your assets, the carrying price is recalculated only on the remaining amount.

If you buy again, the new purchase is added to the existing value for tax purposes.

For this reason, it is normal for the two amounts not to match: the loading price is a dynamic fiscal tool, not simply the total of payments made.

Practical example:

📌 Phase 1 – First purchase

You buy 1 BTC for £10,000.

• amount invested: £10,000

• cost price: £10,000

At this point, the two values are the same.

📌 Phase 2 – Partial sale

The value of BTC rises and you decide to sell 0.5 BTC at £15,000 (so you collect £7,500).

From a tax perspective, the following occurs:

• the cost price of the 0.5 BTC sold was £5,000

• you have realised a capital gain of £2,500 (£7,500 – £5,000)

You now have 0.5 BTC left in your portfolio.

• remaining cost price: £5,000

• total initial investment: still £10,000

👉 As you can see, you invested £10,000, but the current cost price of your portfolio is £5,000 because half of it has been sold.

📌 Step 3 – New purchase

You then buy 0.5 BTC at £12,000.

• new investment: £6,000

• updated total cost price: £5,000 (remaining) + £6,000 (new purchase) = £11,000

What does all this mean?

Over time:

• you have invested a total of €16,000 (€10,000 initially + €6,000 later).

• you have already cashed in €7,500.

• the current carrying price of your BTC is €11,000.
