How This Calculator Works

Front-end DTI uses only your housing costs (mortgage/rent + property taxes + insurance + HOA) divided by gross income. Mortgage lenders look at this number first.

Back-end DTI adds all your other debt payments to the housing costs. This is the more important number for overall financial health and is what most people mean when they say "DTI ratio."
