About CryptoMathly
CryptoMathly is an independent website that builds free calculators and guides for people who buy, hold, stake, mine or trade cryptocurrency. Our goal is simple: help you see the real numbers before you make a decision — after fees, after tax and with your risk measured.
What we offer
- Six calculators covering profit and loss, dollar-cost averaging, crypto tax in the United States, United Kingdom and Canada, Bitcoin mining profitability, staking yield and trading position size.
- Five languages: English, French, Spanish, Russian and Chinese.
- Practical guides that explain the math behind each calculation with worked examples.
How our calculators work
Every calculation runs locally in your web browser. The numbers you type are never sent to our servers and we do not require an account. To show current market conditions, your browser requests public data directly from:
- Binance public market-data API — live prices and historical weekly and monthly candles (priced in USDT).
- mempool.space — the current Bitcoin network hashrate used in the mining calculator.
If either source is unavailable, every field can be filled in manually.
Editorial standards
- Formulas are shown on each calculator page so you can check the logic yourself.
- Tax figures are taken from official publications for the 2026 tax year (IRS inflation adjustments, HMRC rates and allowances, and Canada Revenue Agency rates) and are reviewed when rules change.
- Guides are written to explain concepts, not to promote any coin, exchange or investment. We do not accept payment to feature projects.
- When we find an error, we correct it and update the page date.
What we are not
CryptoMathly is an educational resource. We are not financial advisers, tax advisers or a regulated firm, and nothing on this site is a recommendation to buy or sell any asset. Read our disclaimer for details.
