Frequently Asked Questions
Are these crypto calculators free to use?
+
Yes, all calculators on this page are completely free. There is no registration, no API key, and no usage limit. Every calculation runs locally in your browser โ no data is sent to any server.
Do the calculators use real-time crypto prices?
+
The profit/loss and DCA calculators ask you to enter your own price figures, giving you full control over the scenario you want to model. The unit converter lets you enter a custom price per coin to calculate USD values. The mining calculator uses hardcoded network difficulty estimates and also requires you to supply a coin price.
What is the difference between the DCA and Profit/Loss calculators?
+
The Profit/Loss calculator answers a retrospective question: given a specific buy price, sell price, and investment amount, what was the outcome? The DCA calculator answers a forward-looking question: if you invest a fixed amount on a regular schedule at a given annual return rate, how much will you accumulate over time?
Can I use these tools on mobile?
+
Yes, all calculators are fully responsive and work on any modern smartphone or tablet browser. No app installation is required โ just open the page and start calculating.
How accurate are the mining profitability estimates?
+
The mining calculator provides estimates based on hardcoded network difficulty figures that may not reflect current conditions. Network difficulty adjusts approximately every two weeks for Bitcoin, so real-world profitability can deviate from these estimates. Always cross-reference with a live mining pool dashboard before making hardware decisions.
