How this calculator works

Prices
Bitstamp BTC/USD daily closing prices since August 18, 2011. Today's value uses the live Bitstamp price, or Coinbase if Bitstamp is unavailable.
One-off
Buys your amount at the closing price on the date you pick (or the next day with data), then values those bitcoin at today's price.
Weekly or monthly
Buys your amount at the close every week or month from your start date until today, the approach known as dollar-cost averaging.
What it leaves out
Exchange fees, spreads and taxes, and inflation. Real returns would have been somewhat lower. See the full Bitcoin price history.
