Tarkov Experience Levels Documentation

Overview

This document describes the structure and meaning of the levels.json file, which contains experience requirements for all player levels in Escape from Tarkov.

Data Source

All data is sourced from the official Escape from Tarkov Wiki: - URL: https://escapefromtarkov.fandom.com/wiki/Experience - Last Updated: January 25, 2026

File Structure

The levels.json file contains a JSON object where each key represents a player level (1-79) and contains the following properties:

Properties

• exp (number): The amount of experience required to advance from this level to the next level
• Example: Level 5 has "exp": 5824, meaning you need 5,824 XP to go from level 5 to level 6

• Level 1 has "exp": 0 as it's the starting level

• total (number): The cumulative total experience required to reach this level from level 1

• Example: Level 10 has "total": 63723, meaning you need 63,723 total XP to reach level 10

• This is the sum of all exp values from level 1 through this level

• group (string): The level grouping/tier for game mechanics purposes

• Values range from "1" to "16"
• Used internally for various game systems (trader unlocks, quest availability, etc.)

Example Entry

"15": {
  "exp": 34084,      // Need 34,084 XP to go from level 15 → 16
  "total": 177337,   // Need 177,337 total XP to reach level 15
  "group": "4"       // Belongs to group 4
}

Calculation Formula

The cumulative total for any level can be calculated as:

total[n] = Σ(exp[i]) for i = 1 to n

Or in simpler terms:

total[current_level] = total[previous_level] + exp[previous_level]

Notes

• The experience curve becomes significantly steeper after level 60
• Levels 76-79 were added in recent updates
• The highest level gap is between level 78 and 79, requiring over 27 million XP
• Group numbers generally increase with level ranges but don't strictly correlate 1:1

Usage Examples

Finding XP needed to reach a specific level

// To reach level 50 from scratch
const xpNeeded = levels["50"].total; // 9,055,144

Finding XP needed between two levels

// XP needed to go from level 30 to level 40
const xpNeeded = levels["40"].total - levels["30"].total; 
// 4,010,401 - 1,499,338 = 2,511,063

Finding current level from total XP

function getLevelFromXP(totalXP) {
  for (let level = 79; level >= 1; level--) {
    if (totalXP >= levels[level.toString()].total) {
      return level;
    }
  }
  return 1;
}
