Fibonacci Calculator

How It Works

Fibonacci retracement levels identify potential support and resistance areas where price may reverse or pause. The key levels are 23.6%, 38.2%, 50%, 61.8%, and 78.6%. The 61.8% level (golden ratio) is considered most significant. Extension levels (127.2%, 161.8%, 261.8%) project potential profit targets beyond the original move. Enter the high and low prices of a swing move, and this calculator instantly generates all key Fibonacci levels. Many traders combine Fibonacci with other technical analysis tools to confirm trade entries and exits.
