    How we build these tools

    Calculators use only arithmetic you can verify yourself, and each page explains the formula it applies. Data pages state their provider, how often the figures refresh, and what we show when a provider is unreachable — we label delayed data rather than presenting it as current, and we never fill a gap with an estimate.

    Frequently Asked Questions

    Are these tools free?

    Yes. Every calculator on this page is free, needs no account, and runs entirely in your browser — the numbers you enter are never sent to us or stored.

    Do the calculators need live prices?

    No. Each one works from values you supply, which is why they keep working even when a market data provider is unavailable. Our live data pages — Bitcoin fees and the Fear & Greed Index — clearly label how recent their figures are.

    Can I rely on these results for tax reporting?

    No. They are educational aids. Tax rules differ by country and often require a specific accounting method, so use them for understanding, not for filing.
