Formula used

Pool size = selected lowercase + uppercase + digits + symbols. Search space = pool size^length. Entropy bits = length × log2(pool size).

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Best for explaining password search space and choosing safer password-manager settings.

The entropy estimate assumes truly random independent character selection.
Human-made passwords, reused passwords and dictionary-based passwords can be much weaker.
This page is for strength estimation; use a trusted password manager to generate and store real secrets.
Do not send real passwords to chat, email or screenshots.

Master’s Tip

How to use the result well

Master’s Tip: length beats cleverness. A long random password stored in a password manager is better than a short memorable pattern with substitutions.

Method

Pool size = selected lowercase + uppercase + digits + symbols. Search space = pool size^length. Entropy bits = length × log2(pool size).

A 16-character password using lowercase, uppercase, digits and symbols has a pool around 94 characters. Entropy is 16 × log2(94), about 104.9 bits.

Assumptions

The entropy estimate assumes truly random independent character selection.
Human-made passwords, reused passwords and dictionary-based passwords can be much weaker.
This page is for strength estimation; use a trusted password manager to generate and store real secrets.
