Kubera review: is $250 a year worth it for one balance sheet?

We linked a Coinbase account, a self-custody wallet, a brokerage account and a checking account to Kubera and left it running for a month, mostly to answer one question: does a single balance sheet spanning crypto and traditional assets earn its $250 annual fee, or is that a price built for portfolios much larger than a typical reader's.

One page, several account types

Most crypto portfolio trackers stop at wallets and exchanges. Kubera goes further, pulling in banks, brokerages, private stock, real estate, vehicles and jewelry alongside your on-chain holdings, and showing all of it as one net worth number rather than a pile of separate apps. Connecting our crypto side took a few minutes through standard exchange API keys and a public wallet address; the checking account synced through Plaid with no surprises.

That single view is genuinely useful the moment your money lives in more than two or three places. Watching a market swing move both our crypto and brokerage balances on the same screen, in the same currency, told us something a separate crypto app and a separate brokerage app never would on their own.

What $250 a year buys, and what $2,500 buys

Kubera's Essentials plan costs $250 a year and covers the core balance sheet, connected accounts and the estate-planning Dead Man's Switch. Step up to Black at $2,500 a year and you get ownership tags for splitting assets across people and trusts, plus nested portfolios that track money moving between them, features aimed at family offices and advisors rather than an individual with a few accounts.

For most readers of a crypto review, Essentials is the relevant tier, and $250 a year works out to about $21 a month, more than a coffee subscription but less than most paid tax software plans. Whether that is worth it depends entirely on how many separate apps you would otherwise be checking; if your whole net worth sits in one exchange account, you don't need this.

The Dead Man's Switch is not just marketing copy

We tested the inactivity feature by setting a short check-in period and letting it lapse. Kubera sent multiple warning prompts before granting our designated beneficiary read-only access, and it let us set a backup beneficiary in case the first one is unreachable. For anyone holding crypto that a family member would otherwise have no way to find after an emergency, this is a real feature, not a checkbox on a marketing page.
