Enter the length of the longer period in years (e.g., 2 for 2 years). T₂ must be greater than T₁.

Formula:

The Forward Rate (F) is calculated using the following formula:

F = [((1 + S₂/100)T₂ / (1 + S₁/100)T₁))(1 / (T₂ - T₁)) - 1] * 100

Where:

  • F = Forward Rate (as an annualized percentage for the period from T₁ to T₂)
  • S₁ = Spot Rate for Shorter Period T₁ (annualized percentage)
  • T₁ = Length of Shorter Period (in years)
  • S₂ = Spot Rate for Longer Period T₂ (annualized percentage)
  • T₂ = Length of Longer Period (in years)

Note: T₂ must be greater than T₁.
