Housing and Total Debt to Income Calculator
Calculate housing and total debt ratios from gross monthly income and recurring debt payments.
Calculate housing and total debt ratios from gross monthly income and recurring debt payments. Example result: housing dti (%) = 30%. Compare your own inputs below. Estimates depend on the stated assumptions and are not a quote or forecast. Defaults are illustrative, not recommendations.
Your result
- Housing DTI (%)
- 30%
- Total debt-to-income (%)
- 37.5%
- Gross income left after listed debts
- $5,000.00
With the example inputs, housing dti (%) is 30%. Use the all-in housing cost, including taxes, insurance and association dues. A ratio based on gross income leaves out payroll deductions and everyday living expenses.
How to use this housing and total debt to income calculator
- Gross monthly income: enter the amount in your selected currency. The worked example uses $8,000.00.
- All-in monthly housing payment: enter the amount in your selected currency. The worked example uses $2,400.00.
- Other monthly debt payments: enter the amount in your selected currency. The worked example uses $600.00.
Start with figures from the same statement date or planning period. Calculate once, save scenario A, then change one assumption to understand its effect. The comparison shows B minus A; a positive difference means the result increased, which is not automatically better.
Formula and calculation method
Housing DTI = housing / gross income × 100; total DTI = (housing + other debts) / gross income × 100.
The calculator evaluates this relationship directly in your browser. The displayed precision is for readability and does not imply a guaranteed outcome. Time periods and rate conventions matter: use the exact units in each input label and avoid mixing monthly and annual values.

Two worked examples
1. Illustrative planning scenario
Gross monthly income = $8,000.00; All-in monthly housing payment = $2,400.00; Other monthly debt payments = $600.00.
Apply the stated formula with these inputs. Monetary examples use USD; percentages are divided by 100 inside the calculation. Intermediate calculations retain full precision and displayed amounts are rounded.
| Output | Calculated result |
|---|---|
| Housing DTI (%) | 30% |
| Total debt-to-income (%) | 37.5% |
| Gross income left after listed debts | $5,000.00 |
2. Simplified calculation check
Gross monthly income = $10,000.00; All-in monthly housing payment = $2,000.00; Other monthly debt payments = $1,000.00.
Apply the stated formula with these inputs. Monetary examples use USD; percentages are divided by 100 inside the calculation. Intermediate calculations retain full precision and displayed amounts are rounded.
| Output | Calculated result |
|---|---|
| Housing DTI (%) | 20% |
| Total debt-to-income (%) | 30% |
| Gross income left after listed debts | $7,000.00 |
The second example uses simpler inputs to make the arithmetic easier to check. It is also included in the automated regression suite. These examples illustrate the model and are not market averages, live offers or personalized advice.
Assumptions and limitations
Not an underwriting decision or a universal qualifying threshold. Debt definitions vary by lender; the remaining amount is before tax and living costs.
Use this output to frame a question or compare consistent scenarios. Reconcile any decision involving an actual product, employment agreement or financial statement with its underlying documents. If a contract uses different rounding or timing, its result may differ from this estimate.
Frequently asked questions
Do utilities count as monthly debt?
Usually DTI focuses on required debt and housing payments. Utilities still matter for affordability even when a lender excludes them from DTI.
How do I interpret the housing dti (%) result?
Use the all-in housing cost, including taxes, insurance and association dues. A ratio based on gross income leaves out payroll deductions and everyday living expenses.
What assumptions can change this estimate?
Not an underwriting decision or a universal qualifying threshold. Debt definitions vary by lender; the remaining amount is before tax and living costs.
Can I compare two scenarios without creating an account?
Yes. Save scenario A, change one or more inputs to create scenario B, and compare each result with its difference. Neither scenario requires an account.
Can I use this calculator in another currency?
Yes. Select a display currency and enter every monetary input in that currency. This changes formatting only; it does not convert exchange rates or apply local laws. The static worked examples are in USD.
