Using a Fibonacci retracement calculator can help you quickly and accurately find key price levels during market pullbacks. Whether you’re trading stocks, forex, or crypto, this tool removes guesswork and gives you instant technical zones to work with.
In this post, you’ll learn how to use a Fibonacci retracement calculator, including a real example with step-by-step instructions.
What Is a Fibonacci Retracement Calculator?
A Fibonacci retracement calculator is a tool (online or manual) that computes the retracement levels between a swing high and swing low based on common Fibonacci ratios:
23.6%, 38.2%, 50.0%, 61.8%, and 78.6%
These levels are used to anticipate support and resistance areas where price may reverse or consolidate.
✅ When Should You Use It?
- After a strong uptrend or downtrend
- To plan entries on pullbacks
- To calculate stop-loss and profit targets
- When your platform does not automatically draw Fibonacci levels
✅ How to Use a Fibonacci Retracement Calculator
Step 1: Find the Swing High and Low
Identify the most recent impulse move. For example:
- Swing Low: $100
- Swing High: $150
Step 2: Input into Calculator
Enter the high and low into the tool. It will calculate retracement levels based on:
iniCopyEditRetracement = High – [(High – Low) × Fibonacci Ratio]
Step 3: Read the Output
Based on $100 (low) to $150 (high), the calculator returns:
- 23.6% = $138.20
- 38.2% = $130.90
- 50.0% = $125.00
- 61.8% = $119.10
- 78.6% = $110.70
These are the price levels to watch during a pullback.
Step 4: Apply to Chart
Plot the calculated values on your chart manually or verify with your platform’s tool.
