Following formula to calculate experience points works for levels 0 - 6:

LEVEL * 500 + (15 * LEVEL * (LEVEL - 1) / 2)

For levels 5 and 6, following formula is added:

(LEVEL - 4) ^ 2

C# code snippet:

   int baseLevel = 500 * level;
   int triangularNumberSequenceModifier = 15 * level * (level - 1) / 2;
   int squareModifier = level - 4 > 0 ? (int)Math.Pow(level - 4, 2) : 0;

   return baseLevel + triangularNumberSequenceModifier + squareModifier;
   
This stops working after level 6.
