Free crypto tools and calculators

Every tool on this page is free, runs in your browser and requires no account. We built them because the same questions come up constantly in reader mail, and because most of the calculators already out there either hide their assumptions or bury the result under an affiliate link.

What each one is for

Рентабельность майнинга

The one we are known for. Put in your hashrate, what the machine actually draws at the wall, and what you pay per kilowatt-hour. It returns daily, monthly and yearly net profit, your break-even date and first-year ROI. It will also tell you plainly when a setup never breaks even, which a surprising number of calculators refuse to do.

DCA-калькулятор

Models what a regular buying schedule would be worth today against a stated average entry price, and compares it with the equivalent lump sum.

Profit and loss

Entry, exit, and both sides of the fee. Returns profit in dollars and percent plus the sell price you would need just to get back to even.

Крипто-конвертер

Any of the top fifty coins to any other, or to US dollars, at live rates.

A word on the numbers

Prices come from CoinLore and are cached for five minutes, so a figure may lag a fast-moving market by a few minutes. Nothing these tools produce is a quote, a valuation or financial advice. Mining figures in particular assume today’s conditions hold indefinitely, and they will not: difficulty adjusts, rewards halve, and electricity contracts change.
