Formula:

The Bond Convexity Calculator uses the following formula to estimate convexity:

Convexity Formula:

Convexity = [ P(+) + P(-) - 2 × P0 ] / [ 2 × P0 × (Δy)2 ]

  • P0: Original Bond Price
  • P(+): Bond Price when Yield Decreases by Δy
  • P(-): Bond Price when Yield Increases by Δy
  • Δy: The magnitude of the Yield Shift (as a decimal, e.g., 0.001 for 0.1%)
