How the Fibonacci levels calculator works

The Fibonacci Levels Calculator is a valuable tool used in technical market analysis to identify potential areas of support and resistance. Based on the Fibonacci sequence, this calculator helps traders determine where price might reverse, pause, or extend during a trend using retracement and extension levels.

To use it, you enter the highest price, the lowest price, and select the trend direction (uptrend or downtrend). The calculator then returns key Fibonacci levels commonly used by analysts to outline zones for entry, exit, or setting stop-loss and take-profit levels.

What are Fibonacci levels?

Fibonacci levels are percentages derived from the Fibonacci sequence, applied to price movements. They represent potential reaction points where the price may pull back or continue in its trend.

The most common retracement levels are:

  • 0%, 23.6%, 38.2%, 50%, 61.8%, 76.4%, 100%

And the typical extension levels include:

  • 138.2%, 161.8%, 200%, 261.8%

These levels are calculated based on the difference between a swing high and swing low (or vice versa), and then applying the percentages to project price zones.

How to use the calculator

To calculate Fibonacci levels, simply enter:

  • Highest Price: the top of the recent price move

  • Lowest Price: the bottom of the price move

  • Trend Direction: choose uptrend or downtrend

The calculator will return:

  • Fibonacci retracement levels – used to identify where a correction might occur

  • Fibonacci extension levels – used to forecast continuation targets beyond the current move

Real example

Suppose you're analyzing a stock that moved:

  • From $15 (low)

  • To $30 (high)

  • Trend: Uptrend

The calculator will display the following retracement levels:

  • 0%: $15

  • 23.6%: $18.54

  • 38.2%: $20.73

  • 50%: $22.50

  • 61.8%: $24.27

  • 76.4%: $26.46

  • 100%: $30

And extension levels:

  • 138.2%: $35.73

  • 161.8%: $39.27

  • 200%: $45

  • 261.8%: $54.27

These values can help identify where the price may face resistance or where to place targets.
