PF2e uses a flat XP system based on creature level relative to party level. Each creature contributes a fixed amount of XP (e.g., a creature at party level is 40 XP). The total maps to difficulty thresholds: Trivial (40), Low (60), Moderate (80), Severe (120), and Extreme (160) for a party of 4.

A moderate encounter costs 80 XP for a party of 4. It's a decent challenge where the party uses some resources but isn't in serious danger. Most encounters in a session should be moderate or lower.
It depends on creature level relative to party level. A single creature at party level +2 makes a moderate encounter. Two at party level also work. The encounter builder calculates this automatically as you add creatures.
XP is based on creature level relative to party level. A creature at party level is 40 XP, one below is 30 XP, one above is 60 XP, two above is 80 XP. The builder handles this for every creature you add.
Severe (120 XP) is a major challenge that drains significant resources and may knock out party members. Extreme (160 XP) is life-or-death and could result in a TPK. GM Core recommends extreme encounters be rare and dramatic.
A classic boss fight uses a single creature 3-4 levels above the party (severe to extreme). You can also pair a creature 2 levels above with a few lower-level minions. The builder lets you experiment and instantly see the difficulty.
