Privacy-first portfolio tracker with PRR *.
* PRR (Personal Rate of Return, aka MWRR or IRR) is the APY of a fixed-rate account that, with the same cashflows as the portfolio, ends up with the same balance.
Future Calculator
Quickly see how your portfolio will evolve based on return rate (prefilled with your PRR), contributions, and withdrawals.
The chart lets you instantly visualize and explore the future evolution of cumulative contributions, withdrawals, and gains, and how compounding will impact your balance over time.
Taxes
FINARKY lets you know the net value of your investments by calculating capital gains taxes for both past and future sales.
Just set your tax brackets and holding periods once, then experiment with different sales combinations to find your optimal mix of gains and taxes, maybe taking advantage of tax-loss harvesting.
The "Sales details" show how sales are distributed among tax lots using FIFO.
Cashflow imports
Stock, crypto, ETF, or mutual fund transactions can be added directly in the app or imported using CSV files from Binance, Coinbase, DEGIRO, Indexa Capital, Nexo, or FINARKY's own format.
To make imports from other platforms easier and faster, the app provides a ready-to-use AI prompt to convert transaction statements into FINARKY's CSV format.
