What does this calculator show?

The What-If calculator answers the classic question: "What if I had bought Bitcoin back then?" You enter an amount and a date, and see how much BTC you would have received and what that position would be worth today.

  • One-time investment at any point in time
  • BTC amount bought, current value and return
  • Value growth charted over time

Methodology & data

For the chosen purchase date we use the daily close, the last price of that calendar day (UTC) in our database (5-minute resolution since 2012, daily data from 2010). For today that is the current price. US-dollar prices are real history; euro values are converted from USD at each day's ECB reference rate. Past performance does not guarantee future results.
