How does damage resistance work?
Armor provides a certain amount of damage resistance against different types of damage. This value is obviously not just substracted from the damage, but I don't see any information in the game on how it actually works.
What is the formula for the reduction of damage base on the damage resistance of your armor?
Best Answer
Damage resistance in Fallout 4 is calculated differently from in the other Fallout games. Instead of being a straight calculation, the damage resistance is based not just on the resistance value, but also on the incoming damage. When your damage resistance is precisely equal to the incoming damage, the damage will be cut in half. Any damage resistance above that shows diminishing returns. The approximate formula, taken from here, is

What does resistance to damage mean?
Resistance to a damage type means that you take half damage when you're hit with damage of that type. You can gain resistance against a damage type, a source of damage, or a specific instance of damage. As always in 5e, when you divide the damage by 2, you'll round up.How do you calculate resistance damage?
For example, each level of difference would subtract (or add) 2% from the resistance. Example 1: Player is level 25, with 35% fire damage resistance. A monster (lvl 25 as well) attacks the player for 1400 fire damage. This would result in final damage of (1400 - 0.35 * 1400) = 910.How does damage reduction work in 5e?
When a creature you can see hits a target, other than you, within 5 feet of you with an attack, you can use your reaction to reduce the damage the target takes by 1d10 + your proficiency bonus (to a minimum of 0 damage).Does Damage Resistance stack NWN?
For the most part, damage resistance does not stack. For each damage type, only the highest resistance granted by a spell or (equipped) item is used.TF2: How Damage Resistances Work
