Orange Abacus is the one place for every Bitcoin calculation and tracking that matters. Free, accurate, no signup.
Every Bitcoin calculator we found either buried the math in a spreadsheet or assumed you already knew what a UTXO was. Every chart tracking difficulty or hash rate read like it was built for miners, not for someone trying to figure out what's actually happening. We got tired of decoding jargon before we could even use the tool.
So we built the calculators and trackers we wanted: plain words, visual results, formulas you can verify. Whether it's your first Bitcoin question or your hundredth, the answer arrives clearly.
Plain English, always. If a concept is complex, we visualize it instead of dressing it up in jargon.
Real Bitcoin price data drives every formula, and every output is checked against primary sources before it ships.

The abacus is the oldest surviving calculation tool in history. It represents transparency — every movement of a bead is visible, every calculation is auditable.
Bitcoin is the modern abacus. A transparent ledger where every "bead" (satoshi) can be accounted for. We chose this symbol to remind you that clarity doesn't require complexity. It only requires the right tool to see it.
Pick a calculator and see your numbers in seconds. No signup required.
