The formula to calculate the Time Interest Earned Ratio (TIER) is:
\[ TIER = \frac{EBITDA}{E} \]
Where:
Let's say the total EBITDA is $50,000 and the total interest expense is $10,000. Using the formula:
\[ TIER = \frac{50000}{10000} \]
We get:
\[ TIER = 5 \]
So, the time interest earned ratio is 5, meaning the company earns 5 times its interest expense.
