The formula to calculate the Ultimate Forward Rate (UFR) is:
\[ UFR = (1 + LTR)^{\frac{1}{T}} - 1 \]
Where:
Let's say the Long Term Rate (LTR) is 0.05 (5%) and the time (T) is 10 years. Using the formula:
\[ UFR = (1 + 0.05)^{\frac{1}{10}} - 1 \]
We get:
\[ UFR \approx 0.00488 \]
So, the Ultimate Forward Rate is approximately 0.00488 (or 0.488%).
