How much have you really earned on Goldsaver?
See the real return on your grams of gold after the 6.9% margin and the 19% capital gains tax—compared to CPI, the US dollar, or a gold ETF—and view gold's overall weight in your portfolio.
Goldsaver shows grams of gold — it won't tell you what that's worth after markup and capital gains tax.
Capitally tracks your gold grams from Goldsaver and shows you how much you are actually earning. You will see your rate of return (MWR and TWR) after accounting for the margin and Poland's 19% capital gains tax (podatek Belki), the cost of the margin over time, and gold's share of your total portfolio—all alongside your IKE, IKZE, and other investment accounts.
Do you also invest abroad? Capitally keeps a record of your purchase costs and helps you prepare your capital gains tax report for multiple jurisdictions, including the Polish PIT-38. We feature end-to-end encryption, no third-party aggregators, and you never have to provide your broker password.
Portfolio analysis app
See the real return, not just the grams
Goldsaver shows your gram balance and current value based on the NBP gold price. Capitally shows your actual earnings after applying the 6.9% margin and the 19% capital gains tax—presented as a rate of return (MWR and TWR) and the weight of gold in your overall portfolio results.
Compare your gold's performance against CPI inflation, the US dollar, or the WIG index to see if it is truly protecting your purchasing power—compared to any gold ETF you might hold through an international broker.
- Choose accurate metricsCalculate returns using MWR, TWR, or ROI depending on your investment type, what you want to measure and what you compare yourself against.
- Benchmark — or discount — by anythingStack up to 10 benchmarks side by side, or discount your return by inflation, a market index, any asset, or even a buy-and-hold version of your own portfolio to see your real and excess returns.
- Identify real return driversSee exactly what affects your returns - capital gains, currency fluctuations, income, fees, and taxes - all clearly broken down.
- Track your true performanceGet accurate metrics that account for all cash flows, reinvested dividends, and timing effects that most platforms ignore.
Your own portfolio organizer
Combine your gold with IKE, IKZE, and local brokers
Few people hold Goldsaver on its own — there's usually a Bossa account, eMakler, IKE (a Polish tax-advantaged retirement account), IKZE, sometimes Polish government bonds or Interactive Brokers alongside it.
Capitally connects these accounts in a single view, groups them by your goals (retirement, children, passive income), and converts everything to your base currency—showing how much your gold actually weighs in your portfolio and how your risk is distributed, all without ever sharing your broker passwords.
- Create nested account foldersBuild your accounts into subfolders that mirror how you manage your finances. This makes it easier to navigate, track, and compare different portfolios - so you always know exactly where to find what you need.
- Tag accounts, assets, and transactions flexiblyAdd custom tags on three levels - accounts, assets, and transactions - allowing you to filter and analyze your data in detail. Even the smallest details become easy to compare and track.
- Organize assets by Categories, Regions, and SectorsMarket assets are automatically categorized by kind, geography, and sector. You can categorize your custom ones too. You can instantly see your diversification level and exposure.
- Customize categories to fit your styleCapitally doesn’t just fit your data into predefined structures - you can modify existing categories or create your own, ensuring that all imported assets match your personal organization style.
- Save and pin your favorite views as bookmarksPin your most-used portfolio views to the main menu. Access your key insights instantly - without repeating their setup every time.

"Really pleased to be part of Capitally’s clients! Love the fact that it brings so many functionalities within an efficient interface. Every time I think of something I'd like to do or a piece of data I'd like to have, I always find a way to get it. It's amazing! I’ve also added a shortcut on my iPhone’s home screen, so I can easily access all my data even when I’m away from home. Perfect!"

"I'm really impressed by the quality and versatility of the app. I like that I can customize almost anything. I wanted to have a view of all of my family's assets in one place and the possibility to filter and organize data in any way I want, which is fantastic with the tags. The features that I love the most are the tags, the IRR data, the filtering capabilities and the X-Ray graph."

"As a finance director at a non-profit foundation, I needed a solution that could handle our complex investment mix - from managed funds to real estate. Capitally's flexible import options made it simple to track everything in one place. The affordable price means more of our budget goes to our mission. It's exactly what we needed to get our investment tracking in order."

"I just wanted to share how brilliant your tool is for managing investments. It is so comprehensively thought-through and the ease with which it can be used is admirable. I used to actively manage my investments via Excel, but this helps to save a lot of time and effort. I'm very impressed!"

"Capitally is an absolutely great tool that allows you to grasp all your investments at a glance, thanks to its clear and well-designed appearance. At the same time, it provides practically unlimited possibilities for exploring data. The whole thing works equally well on a computer and a phone. As a user, I can count on excellent support (thank you!). I also like the pace of development and the features being added - since I purchased the license, the ability to calculate tax liabilities has been introduced, and I also have an early version of options support - something no other solution I know of offers. I definitely recommend it!"

"Not only does it provide a real value-add through tax reporting (others charge a monthly fee for only having pre-made portfolio analyses without the ability to customize while requiring the user to still use another way to do taxes), but it also excels at the various kinds of integrations of accounts, assets and currencies."

"I spent 4 years building my 16MB Excel spreadsheet for portfolio tracking. In just two evenings with Capitally, I replicated everything and got even better analytics!

This is next-level software and support! 😂"

"Capitally allowed me to transition from overcomplicated spreadsheets that needed to be updated manually (but never was) I used for tracking my investments, to just seeing the data at a glance, automatically updated and ready for me to analyze.

"The game changer that Capitally brings is that it has a very high degree of customization when it comes to selecting assets and recording transactions. For me the differentiator is the ability to record transactions in a currency that differs from the asset currency. My investment portfolio spans multiple global markets and accounts and normal portfolio tracking tools just don't recognize the fact that I may be purchasing a given equity in more than one currency in different accounts."
Stuart Davidson

"I tried Portfolio Performance, but quit it multiple times because of errors in currency handling, importing is too clunky and error-prone in general and there’s a lack of automatic adjustments for dividends and splits.

Frequently asked questions
No. Capitally never connects to your bank or broker through Plaid, Yodlee, or any other open-banking aggregator — no shared password, no read-only API token, no third party in the data path. Data comes in by CSV or Excel upload, paste from a spreadsheet, or manual entry, with native presets for most major brokers.
That is a precision choice as much as a privacy one, and it means no background auto-sync. Is my data safe? explains both.
Yes. One project holds any number of accounts — personal, company, trust, IRA, ISA, IKE/IKZE — plus the liabilities that finance them, so one net-worth view nets debt against holdings. Every metric works at any level: per account, per filter, or across everything.
When two entities must never appear in the same report, give each its own project — same login, fully isolated data. Projects covers which side of that line an entity belongs on.
TWR judges the strategy, MWR judges your result as an investor. Time-weighted return strips out when you added or withdrew money, which makes it the fair one to compare against a benchmark. Money-weighted return — also called IRR — includes your cashflow timing, so it tells you what the portfolio actually did for you.
Capitally computes both, plus ROI, for every account and for the whole portfolio, and any of them can be discounted by a benchmark for a real or excess return. Calculating returns has the worked examples.
Yes. Capitally is built and operated under GDPR: servers and databases sit in EU data centres, and your portfolio data is end-to-end encrypted on your device with AES-GCM, so we cannot read it even if asked.
Export and permanent deletion are both one-click operations inside the app, with no email or support ticket required. Is my data safe? covers the encryption and hosting model; the Privacy Policy is the full legal text.
Anything you can put a price on. Stocks, ETFs, mutual funds, currencies, crypto and commodities arrive with automatic pricing and dividend data, options with Greeks; cash, bonds, real estate, private equity, collectibles and liabilities are custom assets you value yourself. Depth is per asset: full transaction history, or periodic balance updates.
Market data lists what is priced natively, and Getting Started has a walkthrough per asset class.
You set the price yourself. Add it as a custom asset — private equity, property, collectibles, a closed fund — and feed in valuations by hand, by paste, or by CSV, as often as you get them.
From there it behaves like a listed position: cost basis, TWR, MWR, FX attribution and yield-on-cost all compute the same way, and dividends, rent or expenses can be logged against it. Between valuations Capitally holds the last price forward, or interpolates if you prefer.
