Use the following information to calculate the interest rate on a $30-$year Treasury Bond.

Inflation: next three years $=4\mathrm{.}5\%$

year $4-5=3\mathrm{.}5\%$

year $6$ and beyond $=3\mathrm{.}25\%$

Real Risk$-$Free Rate $($r$*)=2\%$

The maturity risk premium is calculated using the formula, MRP $=0\mathrm{.}1\%*($t $1),$ where t $=$ number of years to maturity.
