How is a debt ratio calculated?

Calculating your debt to income ratio is as simple as adding up all of your debt and subtracting it from your income.
Some calculations may exclude things like mortgage payments and property taxes, but to really get a complete picture it’s best to include everything.

DSCR = (Annual Net Income + Amortization/Depreciation + Interest Expense + other non-cash and discretionary items (such as non-contractual management bonuses)) / (Principal Repayment + Interest payments + Lease payments)

Debt ratio is a financial ratio.
It is used to measure the proportion of debt financing in making up total assets.
Its formula is total Liabilities/Total Assets.
It is a good measure to reveal the degree of liquidity risk of a company in terms of financial risk.
