Fibonacci calculator.
Calculate EW-relevant retracement and extension levels from two price points.
Fibonacci retracements and extensions mark where a move is likely to pause or reverse. Enter a swing high and low to get the key levels — 38.2%, 50% and 61.8% pullbacks plus 127.2% and 161.8% extensions — the same ratios Elliott Wave counts use to project targets and place invalidations.

Frequently asked questions
How do I calculate Fibonacci retracement levels?
Pick a clear swing high and swing low. The retracement levels are the percentages (23.6, 38.2, 50, 61.8, 78.6%) of that range measured back from the end of the move — this calculator computes them instantly for both directions.
What is the difference between retracement and extension?
Retracements (under 100%) project how far a pullback may go within the prior move; extensions (127.2%, 161.8%, 261.8%) project targets beyond it, where a new impulse wave often ends.
Which Fibonacci levels matter most in Elliott Wave?
Wave 2 commonly retraces 50–61.8% of wave 1, wave 4 retraces 23.6–38.2% of wave 3, and wave 3 often extends 161.8% of wave 1 — so the 38.2%, 61.8% and 161.8% levels carry the most weight.
