Formula & Methodology
The OIS zero rate is calculated using the following formula:
OIS Zero Rate = (1 + Overnight Index)^(1/Term) – 1 – Spread
The calculator uses this formula to calculate the OIS zero rate based on your inputs.
Real-World Examples
Example 1: If the Fed Funds rate is 1.5%, the term is 3 years, and the spread is 0.2%, the OIS zero rate would be approximately 2.15%.
Example 2: If the EURIBOR rate is 0.5%, the term is 5 years, and the spread is 0.3%, the OIS zero rate would be approximately 1.32%.
Example 3: If the SONIA rate is 0.1%, the term is 2 years, and the spread is 0.15%, the OIS zero rate would be approximately 0.45%.
