Using this precise Fibonacci levels calculator, you can quickly plot hypothetical Fibonacci retracement or extension levels for any financial instrument.

What Are Fibonacci Levels?

Fibonacci levels and the Fibonacci sequence are not secret ratios or inherent price patterns embedded in the market. Rather, they are a popular method or technical indicator used to analyze asset price movements in financial markets. Like other widely used indicators, their effectiveness largely comes from a self-fulfilling effect created by a large number of traders watching and acting on them.

Fibonacci levels are generally divided into two categories: retracement levels and extension levels. Retracement levels are used after an asset price makes a new high in an uptrend or a new low in a downtrend, when traders assess whether a trend may be nearing a temporary pause or correction. During consolidation or corrective phases, prices often react around key Fibonacci retracement levels.

Major Fibonacci Retracement Levels

Commonly used Fibonacci retracement levels include: 0.236, 0.382, 0.500, 0.618, 0.764.

On the other hand, Fibonacci extension levels are applied during trend continuation phases. Prices may first retrace to a Fibonacci retracement level and then continue in the original trend direction to make new highs or lows. Alternatively, after a period of consolidation, prices may resume the original trend directly without touching every retracement level.

Major Fibonacci Extension Levels

Common Fibonacci extension levels include: 0.382, 0.618, 1.000, 1.382, 1.618.

Just as the golden ratio itself does not possess any so-called “mystical rules,” Fibonacci ratios are not magical laws of price behavior. They are simply mathematically interesting proportions that were later widely adopted by traders.

Because this technical indicator is closely watched by traders around the world—including many professionals—large numbers of buy and sell orders tend to cluster around these price levels, which often makes Fibonacci levels appear highly effective in real markets.

How to Use the Fibonacci Levels Calculator

Select the trend direction: Choose “Uptrend” or “Downtrend” in the “Trend Direction” field to simulate a rising or falling market. For example, suppose we want to calculate Fibonacci retracement levels for EUR/USD in an uptrend to identify a potential entry level.
Select the type: Select the “Retracement” radio button to calculate retracement levels. To calculate target levels, choose “Extension.”
Enter the low price: In the “Low Price” field, enter the lowest price of the EUR/USD pair at the start of the uptrend, for example 1.16653.
Enter the high price: In the “High Price” field, enter the highest price reached during the current uptrend, for example 1.20552.
Click the “Calculate” button: The calculator will automatically generate the corresponding Fibonacci retracement or extension price levels.

Example and Interpretation of the Results

The Fibonacci levels calculator uses two extreme points of the price movement (the lowest or highest swing points, referred to as Point A and Point B) and divides the vertical distance between them according to key Fibonacci ratios such as 23.6%, 38.2%, 50%, 61.8%, 78.6%, producing the corresponding retracement price levels.

In the example above, if the lowest point (Point A) of EUR/USD in an uptrend is 1.16653 and the highest point (Point B) is 1.20552, the calculator will generate retracement levels such as 23.6%, 38.2%, and 50.0%, helping traders identify potential support areas.

Using Extension (Projection) Levels

By default, the calculator displays retracement levels. To calculate projection (extension) levels, traders need to enter a target price in the “End Price” field (required). The calculator will then display up to six potential extension levels, reaching as high as 261.8% (the 2.618 Fibonacci level).

Common Fibonacci Levels Used in Live Trading

In financial trading, the three most commonly used Fibonacci retracement levels are 23.6% (0.236), 38.2% (0.382), and 50% (0.500). For extensions, the three most commonly used Fibonacci extension levels are 61.8% (0.618), 100% (1.000), and 161.8% (1.618).

FAQ

What are Fibonacci Levels?

Fibonacci levels are price ratios derived from the Fibonacci sequence (such as 23.6%, 38.2%, 50%, 61.8%, 78.6%, etc.), which appear as a series of horizontal price levels on a chart. Traders typically view these levels as potential support or resistance zones, helping them identify where price may retrace, rebound, or encounter selling or buying pressure.

How are Fibonacci retracement levels used in forex trading?

In a clear uptrend or downtrend, traders first identify the swing low and swing high of the move, then use a Fibonacci retracement tool or this page’s calculator to calculate the retracement levels. Traders observe how price behaves around these levels to identify potential entry points, scaling opportunities, or stop-loss adjustments, helping avoid chasing price movements blindly.

What data do I need to enter to use this Fibonacci level calculator?

Select the trend direction: upward or downward, to reflect the current market movement.
Choose the type: Retracement or Projection (Extension).
Enter the low price and high price of the price move.
To calculate projection levels, you can additionally enter the end price.
Click “Calculate,” and the calculator will automatically generate the corresponding Fibonacci retracement or projection price levels.

What is the difference between Fibonacci retracement and extension levels?

Retracement levels are used to measure how far price may pull back within an existing trend, estimating the depth of a correction. Extension levels are used to project potential price targets once the trend resumes, estimating future price objectives. In short, retracement levels are commonly used for entries or scaling in, while extension levels are often used to plan take-profit targets or partial exits.

Which Fibonacci levels are most commonly used by traders?

For retracements, the most widely used levels are 38.2%, 50%, and 61.8%, followed by 23.6% and 78.6%.
For extensions, common target levels include 61.8%, 100%, 161.8%, and more aggressive levels such as 261.8%.
Trader preferences may vary slightly across instruments and timeframes, but these levels are the most commonly monitored Fibonacci ratios.

Can Fibonacci levels be used as a standalone trading strategy?

It is generally not recommended to rely solely on Fibonacci levels for trading decisions. Fibonacci tools work best as a complementary indicator when combined with trend analysis, support and resistance, chart patterns, moving averages, or price action. When multiple signals align near a Fibonacci level, that price area becomes a more reliable reference for entries, stop-losses, or take-profit levels.
