Debt Service Calculator

Compare your monthly debt payments and housing expenses to your gross household income.

Did You Know?

Mortgage professionals use 2 main ratios to decide if borrowers can afford to buy a home: Gross Debt Service (GDS) and Total Debt Service (TDS). This calculator will give you both.

• GDS is the percentage of your monthly household income that covers your housing costs. It should be at or under 35%.
• TDS is the percentage of your monthly household income that covers your housing costs and any other debts. It should be at or under 42%.

For more information on these calculations, including guidance on which rental income to include in your household income, see Calculating GDS and TDS
