Free tools
Free crypto calculators.
Instant, free, no sign-up. A new tool every week. Every result is plain arithmetic shown with its formula and a chart of your own numbers.
Every calculator
Each one runs in your browser on your own numbers.
Position size calculator
How big should this trade be? Enter what you are willing to lose and where your stop is — get the size in coins and in dollars.
DCA calculator
What would a recurring buy add up to? Compare scenarios for a plan you set up, or replay monthly buys into BTC or ETH on real historical closes.
Get the weekly email
Free, once a week: the market in one read, the coin review of the week, the best finds and the new free tool. Research, not advice. Unsubscribe in one click.
Educational tool, not financial advice. No tax calculators — tax rules depend on where you live, so we leave that to a qualified adviser.
