ratio debt

This debt ratio and the rate of debt service of one and the same?

debt ratio is commonly used United States and the rate of debt service Canada. bbut I am very confused as to whether the debt to income is also used in the U.S.?

First to your second question makes no sense. Second Instead, I'm no expert, but I think they are the reverse: "" debt ratio = debt / income and debt service "ratio = income / debt.
