Fibonacci Retracement Calculator

After a strong move, price often pulls back part of the way before continuing. Fibonacci retracement marks the common pullback points - 23.6%, 38.2%, 50%, 61.8% and 78.6% of the move - and the extension levels project where the next leg might reach. Enter the swing high and low and this tool lays out every level as a price.

How to Use It

1. Choose Uptrend or Downtrend:
   • Uptrend - the swing ran from the low up to the high; retracements are measured down from the high, and extensions project above it.
   • Downtrend - the swing ran from the high down to the low; retracements are measured up from the low, and extensions project below it.
2. Enter the swing high and swing low.
3. Read the retracement and extension prices from the tables.

How the Levels Are Found

The move’s size is the range, $\text{range} = \text{high} - \text{low}$. Each level is that fraction of the range from the end of the move:

• A retracement at level $L$ (uptrend) is $\text{high} - \text{range} \times L$, so 0% is the high and 100% is the low.
• An extension at level $E$ (uptrend) is $\text{low} + \text{range} \times E$, so 161.8% sits above the high by 0.618 of the range.

The 50% level is not a true Fibonacci ratio but is included by long convention.

Notes

Levels are reference points, not predictions, and this is not financial advice. Numbers are unit-agnostic - use whatever price scale you are charting.
