Demo portfolio with made-up data – try it out.

The overview your brokers won’t give you

Each broker shows only its own piece. Capitrea puts the whole picture together – from your transactions, so you never enter anything twice.

All accounts together

FIO, DEGIRO, XTB, Interactive Brokers, Portu, Revolut, eToro, Trading 212, Yahoo Finance, manual trades and cash in one total, in Czech crowns or euros.

Your real return

Gains from sales, dividends after withholding tax, currency effects and a performance chart against the S&P 500 or inflation.

Retirement income

How much you can withdraw from your investments each month and how long the money lasts – in today's money, with worse and better scenarios.

Targets and deposit calculator

Set target weights for your ETFs and with each deposit see what to buy to keep the portfolio balanced.

Built-in MCP server

Capitrea has its own MCP server. Add it as a connector in your AI assistant (Claude, ChatGPT and others) and ask about your portfolio in plain language – the assistant fetches the data itself.

Czech taxes

What you can sell tax-free thanks to the holding test, the CZK 100,000 limit, the 15 and 23 % rates and figures for your tax return.

How the return is calculated

Time-weighted return

How well the investments did – deposits and withdrawals don’t distort it.

Formula

daily changes in value without deposits and withdrawals, compounded over the period

Each day measures by how many percent the investments changed (without that day’s deposits and withdrawals, including dividends), and the days are compounded. It doesn’t matter when and how much you deposited – that’s how funds and indices are measured, so it’s comparable with the S&P 500.
