Debt-to-Income Ratio: What It Is and Why It Matters
Your debt-to-income ratio (DTI) compares your total monthly debt payments to your gross monthly income. It's one of the primary metrics lenders use to assess creditworthiness — and a powerful indicator of financial health.
The formula: DTI = (Total Monthly Debt Payments / Gross Monthly Income) x 100. If you earn $5,000/month and pay $1,500 across mortgage, student loans, and credit cards, your DTI is 30%.
Below 35% is generally healthy. Between 36-49% signals stress and may limit borrowing. At 50%+ more than half your income goes to debt — a serious warning sign. For mortgages, the 28/36 rule applies: housing under 28%, total debt under 36%.
A high DTI means less income is available to invest and build wealth. Every dollar going toward debt repayments is a dollar not compounding in your portfolio.
Reducing DTI involves increasing income, reducing debt (using strategies like snowball or avalanche), or both. Even dropping from 40% to 28% can meaningfully change your financial trajectory.
Tracking DTI alongside net worth and cash flow gives you a complete, three-dimensional view of your financial health.
