Fibonacci Calculator – Retracement & Extension Levels

Use the Online Fibonacci Calculator

Use this free Fibonacci Levels Calculator to quickly plot hypothetical Fibonacci retracement or extension levels for any Forex pair, index, stock or cryptocurrency.

What Are Fibonacci Levels in Trading?

Fibonacci levels are widely used support and resistance levels based on the Fibonacci sequence. They are not magical ratios, but popular price levels that many traders watch, which makes them self-fulfilling in liquid markets like Forex.

Fibonacci Retracement Levels

Fibonacci retracements are applied after a strong move up or down to estimate how far price might pull back before the trend continues. The most popular retracement levels are 23.6%, 38.2%, 50.0%, 61.8% and 78.6% (0.236, 0.382, 0.500, 0.618, 0.786).

Fibonacci Extension Levels

Fibonacci extensions project possible target levels in the direction of the main trend. Common extension levels are 38.2%, 61.8%, 100%, 138.2% and 161.8% (0.382, 0.618, 1.000, 1.382, 1.618).

Key Fibonacci Retracement & Extension Levels

23.6% (0.236) – shallow pullback in a strong trend
38.2% (0.382) – common corrective retracement
50.0% (0.500) – mid-point retracement watched by many traders
61.8% (0.618) – “golden ratio”, deeper but still healthy pullback
78.6% (0.786) – last defense before a trend reversal

Most Used Fibonacci Extension Levels

61.8% (0.618) – conservative take-profit level
100% (1.000) – equal measured move target

How to Use the Fibonacci Calculator Step by Step

1. Select Trend Direction

Choose Up if the market is in an uptrend and you want to measure a bullish swing, or Down for a bearish swing.

2. Choose Retracement or Projection

Select Retracement to calculate pullback levels within the trend, or Projection (Extension) to generate potential profit targets.

3. Enter the Low and High Price

For an uptrend, input the swing low as the Low price and the swing high as the High price. For a downtrend, reverse the inputs.

4. (Optional) Enter the End Price for Projections

When using projections, add the End price so the calculator can show up to six possible Fibonacci extension levels, up to 261.8% (2.618).

5. Click “Calculate” and Read the Levels

The calculator will instantly display the Fibonacci retracement or extension prices. You can then copy these levels to your trading platform to build your trading plan.

How Traders Use Fibonacci Levels in Forex

Using Fibonacci Retracements as Entry Zones

Many traders wait for price to retrace to the 38.2%, 50% or 61.8% levels to look for reversal candlestick patterns or confluence with support and resistance before entering in the direction of the trend.

Using Fibonacci Extensions as Take-Profit Targets

Fibonacci extensions are often used to set realistic profit targets. For example, a trader might scale out a position at the 61.8% extension and leave a runner to the 100% or 161.8% extension.

Combining Fibonacci with Other Technical Tools

Fibonacci levels work best when combined with price action, trendlines, moving averages or support/resistance zones, rather than being used alone.

A Fibonacci calculator is used to quickly calculate Fibonacci retracement and extension levels. Traders use these levels to identify potential support, resistance, entry points, and profit targets in markets such as Forex, crypto, stocks, and indices.

How do I calculate Fibonacci retracement levels?

To calculate Fibonacci retracement levels, choose a price swing (high and low), then apply Fibonacci ratios such as 23.6%, 38.2%, 50%, 61.8%, and 78.6% to measure potential pullback levels within a trend. This calculator does the math instantly for you.

What are the most important Fibonacci retracement levels?

The most commonly used Fibonacci retracement levels are 38.2%, 50%, and 61.8%. Many traders consider these levels as high-probability areas to look for price reactions when trading pullbacks.

What is the difference between Fibonacci retracement and extension?

Fibonacci retracement levels measure potential pullbacks within an existing trend, while Fibonacci extension levels project possible price targets beyond the current high or low. Retracements help with entries, and extensions are often used for take-profit targets.

Can beginners use Fibonacci levels in trading?

Yes. Fibonacci levels are beginner-friendly because they provide clear visual price areas. However, beginners should avoid using Fibonacci alone and combine it with trend analysis and proper risk management.

Does Fibonacci retracement work in Forex trading?

Fibonacci retracement works well in Forex because the market is highly liquid and many traders watch the same levels. Like all technical tools, it performs best in trending markets rather than ranging conditions.

Where should I place stop loss using Fibonacci levels?

Traders often place stop losses slightly beyond key Fibonacci levels, such as below the 61.8% retracement in an uptrend. This helps protect the trade if price breaks the structure of the trend.

Does Fibonacci trading guarantee profits?

No. Fibonacci tools do not guarantee profits. They are best used as part of a complete trading strategy that includes confirmation, position sizing, and strict risk management.
