Crypto Tax Gain Calculator: Realized Gains, Cost Basis & ROI

Crypto Tax Gain Calculator: realized gains, cost basis and ROI

Crypto Tax Gain Calculator

Sold crypto and want to see your realized gain or loss? Enter what you paid (including the buy fee) and what you received (after the sell fee). The calculator shows your cost basis, net proceeds, realized gain or loss, and ROI. Educational illustration only — not tax advice and not a tax return.

Please enter valid non-negative numbers for all amounts.

Cost basis (buy + buy fee)–
Net proceeds (sell − sell fee)–
Realized gain / loss–
Return on investment (ROI)–
How it is calculated. Cost basis = buy amount + buy fee. Net proceeds = sell amount − sell fee. Realized gain/loss = net proceeds − cost basis. ROI = realized gain/loss ÷ cost basis × 100. This matches the worked example many tax guides use: $5,000 buy + $25 fee → $5,025 basis; $7,000 sell − $35 fee → $6,965 proceeds; gain $1,940; ROI 38.61%.
Assumptions and limits. This is a single-sale calculator: it assumes the buy amount you enter is the full cost basis of what you sold. If you bought the same asset multiple times and sold only part of it, the basis must be allocated across lots (average cost, FIFO, or another method your tax rules allow) — that needs the multi-trade version, coming next. Fees are treated as added to basis on the buy side and subtracted from proceeds on the sell side, the common textbook treatment; your jurisdiction may differ. Currency conversion is not applied — enter all amounts in one currency.

For information only. Crypto tax rules differ by country and change over time; this calculator is not tax advice, not a recommendation to buy or sell any asset, and not a substitute for a tax professional. Figures: U.S. IRS Notice 2014-21 treats virtual currency as property; Canada's CRA guidance covers crypto dispositions — check the current official guidance for your tax year before filing.

What Is a Blockchain? A Plain-Language Explainer

Image
A blockchain is a shared record book. Entries are grouped into blocks, and each block carries a cryptographic fingerprint of the block before it, locking the blocks into a chain. On a public blockchain like Bitcoin's, copies of that record book live on many computers at once, and no single company owns it. Change an old entry and you have to rewrite every block after it — and get the rest of the network to accept the rewrite. That is the whole idea, and everything else is detail. Start with the record book, not the coin Strip away the coin and a blockchain is a ledger: a list of who sent what to whom, in what order. Bitcoin's ledger records bitcoin transfers. Other chains record other things. The problem the design solves is agreement: when nobody runs the central office, how do all the record-keepers agree on which entries happened, and in what order? The idea reached the public in October 2008, when a paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System,...

Crypto Taxes Explained: What Actually Triggers a Tax Bill in 2026

Image
No — buying crypto and holding it does not create a tax bill. In the United States, the IRS treats cryptocurrency as property, not currency (IRS Notice 2014-21), which means tax is triggered only when you dispose of coins or receive them as income. Selling for dollars, swapping one coin for another, or paying for something with crypto can create a taxable event. Buying and holding cannot, no matter how much the price moves. That single distinction — tax happens when you give up a coin, not while you own it — clears up most of the confusion around crypto taxes. This guide walks through what the IRS actually counts as a taxable event, the real 2026 rate numbers, the one place where crypto gets better tax treatment than stocks, and the new reporting paperwork that started this year. Try the Crypto Tax Gain Calculator → Crypto is property: the rule everything hangs on Because crypto is property, every disposal follows a simple formula: gain or loss = what you received minus what it...

Stablecoins Explained: What They Are and How USDT, USDC, and DAI Differ

Image
A stablecoin is a cryptocurrency designed to hold a steady value against a reference currency — almost always the U.S. dollar. One token is meant to equal one dollar, at all times. The design works only if there is something credible behind that one-dollar promise, and that backing is where stablecoins genuinely differ from one another. The scale is what makes the question matter. As of October 2026, Tether's USDT has roughly $184 billion in circulation, and Circle's USDC has roughly $73 billion — two private dollar tokens moving tens of billions between traders, businesses, and savers every day. They look interchangeable on an exchange screen. They are not. Understanding what sits behind each peg is the whole subject of this post. The One Idea Behind Every Stablecoin Strip away the branding and every stablecoin runs on the same mechanism: confidence in redemption. A token trades at $1 because holders believe they can always get $1 back — by redeeming with the issuer, or by...
