Total Property Expenses = Mortgage Payment + Property Taxes + Insurance Costs + HOA Fees + Maintenance CostsTotal Monthly Debt = Total Property Expenses + Other Debt PaymentsEffective Income = Monthly Income + Monthly Rental Income (if rental income is included)Debt-to-Income Ratio = (Total Monthly Debt ÷ Effective Income) × 100Property DTI = (Total Property Expenses ÷ Effective Income) × 100Property Cash Flow = Monthly Rental Income - Total Property ExpensesMaximum Monthly Payment Room = (Effective Income × Maximum DTI Percentage) - Other Debt PaymentsRemaining Income = Effective Income - Total Monthly DebtThe calculator evaluates your DTI risk level using these standards:
1,000 dollars + 200 dollars + 100 dollars + 50 dollars + 150 dollars = 1,500 dollars1,500 dollars + 1,000 dollars = 2,500 dollars6,000 dollars + 1,500 dollars = 7,500 dollars(2,500 dollars ÷ 7,500 dollars) × 100 = 33.3%(1,500 dollars ÷ 7,500 dollars) × 100 = 20%1,500 dollars - 1,500 dollars = 0 dollars(7,500 dollars × 43%) - 1,000 dollars = 2,225 dollars7,500 dollars - 2,500 dollars = 5,000 dollarsMost lenders use a maximum DTI ratio of 43% for investment property loans. When evaluating an investment property, lenders typically look at both your overall DTI and the property's cash flow.

Some lenders may only count a percentage (typically 75%) of expected rental income to account for potential vacancies and maintenance issues.
