RatioRank

ratiorank.com · a Thurakit OÜ project

Tallinn, October 2026

RatioRank is Thurakit OÜ's tool for keeping track of an investment portfolio and how it is taxed in Spain. It is built for private investors resident in Spain who hold their money across several brokers, want to see it all in one place, and want to reach their annual tax return with the numbers already worked out.

What it does

It brings together holdings from several brokers. Most are loaded from the broker's own statement (DEGIRO, Trade Republic, Trading 212, Revolut, Indexa Capital, Renta 4 or Kraken); Interactive Brokers connects in read-only mode.
It adds the rest of your net worth: cash, property, savings plans and debts.
The Tax tab (Renta, in the app) works out the year's capital gains and losses the way the Spanish tax authority does: first in, first out across every broker, the two-month wash-sale rule, fund switches and options. It produces the year's report as PDF and CSV, ready for filing in Renta Web.
On the website, it scores a portfolio on five ratios (risk-adjusted return, diversification, drawdowns, costs and concentration) and compares it with the IBEX 35 and other indices.

Where it stands

The website is live at ratiorank.com. The iPhone app is in development, with a public beta planned for November 2026. It will be distributed through TestFlight, Apple's app for testing apps before they reach the App Store, and the link will be posted at ratiorank.com/beta. The beta is free and has no in-app purchases.

What it does not do

RatioRank explains; it does not recommend investments. It shows the numbers behind a portfolio and how they are calculated, but it never tells you what to buy or sell. That is the line drawn by the CNMV, Spain's securities regulator: information and calculations, yes; investment recommendations, no.

Nor does it trade, hold money or securities, or have deals with banks or brokers.
