Damage for Physical Attackers
Initial formula from this Google Doc, adjusted for Season 8.
Ignoring Monster Physical Damage Reduction, since unknown. Not considering additive Elemental.
Season 8 Physical Attacker Formula
Base Damage in this context is the initial value that gets multiplied by all the other modifiers.
Your weapons base damage is the value in white brackets on your weapon.
Enhanced Damage is the sum of the weapons enhanced damage with all the enhanced damage from other gear pieces except the other weapons, if dualwielding.
Flat Physical is the sum of all flat physical damage from gear and skills.
Your sources of Attack Damage are Strength (1% per point), stats on gear and skills.
Armor Break increases the physical damage enemies take. The most common source of Armor Break is Crushing Blow, which provides a 10% increase per stack, up to a maximum of 5 stacks. Additional sources of Armor Break are additive to the Crushing Blow effect.
Deadly Blows deal 35% increased physical damage
S8: Deadly Blow went from 50% to 35%, we got some Deadly Blow Effect on some few items
Critical Strikes deal more damage based on your Critical Strike Damage. Critical Strike Chance cap is 95%
Extra Damage is a multiplier for the damage you deal to enemies with certain debuffs. The debuffs are Bleeding, Burning, Poisoned, Stunned, (Deep) Frozen and Stasis.
Note: After further testing, it seems that the different extra damage modifiers are additive with each other and not multiplicative like previously stated.
Season 7 introduced a few new item affixes that can grant you extra damage:
Shadowburn
Frostbitten
Monsters Afflicted with Ailments, this one works once for each ailment (as of Season 7), changed to once for any ailment count in Season 8
From Season 9 onwards, there will be new variants like "Extra Fire to Burning Monsters" which (should) only provide extra damage if you deal Fire damage
Skill Attack Damage is what your skill shows on the tooltip. It is a multiplier for your total damage.

Damage for Casters
Not specifiying a certain element, since casters usually only do one element. Ignoring Hybrid skills. Only showing per Hit damage, without other multipliers like Elemental Breaks, Augment Damage%, Hit rate etc.
Season 8 Caster Damage Formula
Base damage is calculated by summing up the base damage of your skill and flat skill damage.
Synergy modifiers are calculated by summing up the synergy values of your skill and the listed attribute, usually intelligence.
Magic Skill Damage and your increases to your skills element are summed up for further calculations
Your damage is calculated against an Enemies resistances, this modifier is representing this penalty depending on your enemy resistance ignore stats. Currently using 85% Monster Resistances as a base value.
Extra Damage is a multiplier for the damage you deal to enemies with certain debuffs. The debuffs are Bleeding, Burning, Poisoned, Stunned, (Deep) Frozen and Stasis.
Note: After further testing, it seems that the different extra damage modifiers are additive with each other and not multiplicative like previously stated.

From Season 9 onwards, there will be new variants like "Extra Fire to Burning Monsters" which (should) only provide extra damage if you deal Fire damage
Note: There can be other factors to your damage, which are often multiplicative with the listed ones. These may include sources of Break and Damage from your Skills Sub Skill tree or effects from other skills.

Base Damage, or sometimes called Base Damage Scaling is the damage of your skill that it gains per level without any other modifiers. This is usually in the range of [3-30].
To calculate the Base Damage, you need to look at the tooltip of your skill and reverse calculate it by dividing the damage by your synergy %, increased damage %, subtracting the flat damage from other sources and dividing by your skill level. You can roughly estimate the Base Damage by looking at an empty character, unspeccing the skill tree and checking the level 0 tooltip. Then divide out the intelligence synergy to get the Base Damage.
