Not all debt is equally burdensome. The debt-to-income ratio is a useful measure of whether your debt level is manageable — and what lenders, financial planners and your own budget tend to use as a reference point.
Your debt-to-income ratio (DTI) measures how much of your gross monthly income goes toward debt payments. It is calculated as:
DTI = Total monthly debt payments ÷ Gross monthly income × 100
Expressed as a percentage
For example: if your gross monthly income is $5,000 and your total monthly debt payments (credit cards, car loan, student loan, mortgage) add up to $1,500, your DTI is 30%.
Important: DTI uses gross income (before taxes), not take-home pay. It also uses minimum payments on revolving credit, not what you actually pay.
Include all recurring monthly debt obligations:
Do not include: utilities, insurance, groceries, subscriptions or other non-debt living expenses. DTI is specifically about debt obligations.
Many lenders consider 36% or below as a healthy DTI, though the specific thresholds vary by lender and loan type. For conventional mortgages, many lenders look for a DTI of 43% or lower — though some allow higher with compensating factors. FHA loans may allow up to 50% in some circumstances.
These thresholds are general guidelines based on commonly cited industry standards. Actual lender requirements vary and should be confirmed directly. This is general information, not financial advice.
Beyond borrowing, DTI tells you something important about financial breathing room. If 40%+ of your gross income goes toward debt payments, that leaves less room to save, handle unexpected costs and build financial security.
A DTI above 35% does not mean you are in crisis — it means debt repayment is a significant part of your financial picture and worth addressing actively. Reducing DTI over time, by paying down debt or increasing income (or both), broadens your options and reduces financial stress.
DTI also does not capture the full picture. High-interest credit card debt at 20% DTI could be more financially damaging than a low-interest student loan at 25% DTI. The rate and type of debt matters alongside the total payment burden.
If your DTI is above a level you are comfortable with, there are two levers: reduce debt payments or increase income (ideally both).
Reduce debt payments by accelerating payoff of high-balance or high-rate accounts. Each debt you pay off reduces your monthly obligation and your DTI. Starting with the highest-rate debt reduces total interest; starting with the smallest balance frees up a payment sooner.
Increase income through a raise, career change, side hustle or additional hours. More income does not just reduce DTI mathematically — it also provides more money to put toward debt payoff, accelerating the process.
Avoid adding new debt while working to reduce your ratio. New borrowing makes the problem larger, not smaller, even if the new payments feel manageable in isolation.
