What is Fallout 4 Build Calculator?

A Fallout 4 Build Calculator is a specialized tool used by players to plan their character’s initial and long-term attribute distribution. In the post-apocalyptic Commonwealth, your S.P.E.C.I.A.L. stats (Strength, Perception, Endurance, Charisma, Intelligence, Agility, and Luck) act as the foundation for your survival.

By using this calculator, you can determine if your character will have enough Strength to carry heavy weapons, enough Intelligence to hack terminals, or enough Agility to sneak through raider camps undetected. It helps in avoiding “wasted” levels by ensuring you meet perk prerequisites early on.

How to Calculate Fallout 4 Build (Example):

  1. Allocate S.P.E.C.I.A.L.: You start with 1 point in each and have 21 additional points to spend.
  2. Calculate HP: If your Endurance is 5 and you are Level 10, your HP will be calculated based on the base value plus level scaling.
  3. Verify Perks: Check if your Charisma is at least 6 to unlock the “Local Leader” perk for settlement building.

Frequently Asked Questions (FAQ):

  • How many starting points do I get? You start with 21 points to distribute among the 7 S.P.E.C.I.A.L. attributes, which all begin at 1.
  • Can I increase stats later? Yes, every time you level up, you can choose to increase a S.P.E.C.I.A.L. stat by 1 point instead of picking a Perk.
  • What is the maximum stat level? The natural cap is 10, but Bobbleheads and gear can push these stats to 11 and beyond.
  • How does Intelligence affect XP? Every point in Intelligence increases your XP gain by approximately 3%.
