📐 Formula

Expected Utility EU = p1 × U(w1) + p2 × U(w2)
Expected Wealth EW = p1 × w1 + p2 × w2
Certainty Equivalent CE = U⁻¹(EU)
Risk Premium = Expected Wealth (EW) - Certainty Equivalent (CE)

💡 Practical Example

50% chance of $10,000 vs 50% chance of $40,000 under U(w) = √w: Expected Wealth EW = + = $25,000. Expected Utility EU = + = 150 utils. Certainty Equivalent CE = 150^2 = $22,500.00.
