How to Use This Tool

  1. Select curve type: Choose between linear, exponential, or custom XP progression
  2. Set max level: Adjust the slider to set your game's maximum level
  3. Configure base XP: Set the XP required for level 1
  4. Adjust curve parameters:
    • For linear: Set how much XP increases each level
    • For exponential: Adjust the growth factor
    • For custom: Write your own JavaScript formula
  5. Generate curve: Click the button to create your XP progression
  6. Review results: Examine the chart and data table to verify your curve
  7. Export: Download your XP curve as JSON or CSV for use in your game

Benefits of XP Curve Planning

Frequently Asked Questions

What's the difference between linear and exponential XP curves?

Linear curves add a fixed amount of XP per level (e.g., +100 XP each level). This creates steady progression where each level takes slightly less time relative to the player's power.

Exponential curves multiply the XP requirement by a factor each level (e.g., 1.2× each level). This creates accelerating progression where higher levels take significantly more time.

Which curve type is best for my game?

The best curve depends on your game design:

  • Linear: Good for games with consistent progression and many levels
  • Exponential: Good for games with prestige systems or where you want to slow high-level progression
  • Custom: Best when you need specific control over the progression curve
How do I write a custom XP formula?

The custom formula uses JavaScript syntax. You have access to:

  • level - The current level (1 to maxLevel)
  • baseXP - Your configured base XP value

Example formulas:

// Quadratic growth
return baseXP * level * level;

// Slow early, fast late
return baseXP * Math.pow(level, 1.5);

// Step function (same XP for groups of levels)
return baseXP * (Math.floor((level-1)/5)+1) * 100;
How do I determine good values for base XP and increments?

Consider:

  1. How much XP you expect players to earn per minute/hour
  2. How long you want level 1 to take
  3. How long you want max level to take
  4. The relative power increase between levels

Start with rough estimates, generate the curve, then adjust based on playtesting.

Can I model XP curves from existing games?

Yes! If you know the XP requirements for several levels, you can:

  1. Note the XP values for levels 1, 5, 10, etc.
  2. Try different curve types to match the pattern
  3. Use custom formulas for precise replication
  4. Adjust parameters until your generated curve matches the known values
How do I implement this in my game?

After exporting your curve:

  • JSON/CSV: Import into your game engine and reference the values
  • Formula: Implement the same calculation in your game's code
  • Hybrid: Use pre-calculated values with formula fallback

For large level caps, consider calculating values at runtime using your formula to save memory.
