Result

3.33%

Estimated interest expense ratio based on interest expense divided by total revenue.

Interest expense ratio3.33%
Interest expense used$1,800,000
Revenue used$54,000,000
Interest per $100 of revenue$3.33 per $100
  • $1,800,000 of interest expense against $54,000,000 of revenue gives an interest expense ratio near 3.33%.
  • That means about $3.33 of every $100 of revenue is being absorbed by interest expense in this simple view.
  • Use the result as a broad burden check only, because different businesses classify revenue and financing costs differently.

This is a simple ratio estimate, not financial advice. Revenue timing, nonoperating items, and how interest expense is classified can all affect the result.

Why compare interest expense with revenue?
