Debt Service Coverage Ratio (DSCR)

The ratio lenders use to check whether a property's own rental income is enough to cover its annual loan payments.

Debt Service Coverage Ratio (DSCR) is the number lenders use to check whether a property's own rental income is enough to cover its loan payments, without needing help from the investor's other income. The formula is DSCR = Net Operating Income divided by Total Debt Service. Net Operating Income (NOI) is what's left after collecting rent and paying the running costs of the property, before any mortgage payments. Total Debt Service is the full annual mortgage payment, principal and interest combined, sometimes shortened to P&I.

A DSCR of 1.0 means the property's income exactly covers its loan payment, with nothing left over. Anything below 1.0 means rent alone isn't enough to make the mortgage payment, so the investor has to top up the shortfall from their own pocket every month, similar to negative cash flow. A DSCR above 1.0 means the property earns a cushion above what's owed on the loan, which is exactly what lenders want to see before they approve financing.

For example, a rental building with $180,000 in annual NOI and a mortgage payment of $140,000 a year has a DSCR of 180,000 divided by 140,000, which equals 1.29. That means the property earns 29% more than it needs to cover its own debt each year. Drop the NOI to $130,000 with the same mortgage payment and DSCR falls to 0.93, a red flag for most lenders because the property can no longer fully pay for itself.

Lenders don't apply one universal minimum, but a DSCR of 1.20 to 1.25 is commonly cited as the baseline for stabilized investment and commercial property loans, meaning the property needs to earn at least 20 to 25% more than its annual debt payment. Riskier assets, such as single-tenant retail or properties with upcoming lease turnover, often require a higher DSCR, sometimes 1.30 or more, while a stable, well-occupied multifamily building may qualify at the lower end of that range. Always confirm the exact minimum with your lender, since it varies by property type, loan program, and country.

DSCR is easy to confuse with other property metrics because it uses similar numbers. NOI is the income figure that feeds into DSCR, but NOI on its own doesn't tell you whether that income is enough to cover a specific loan. Cash-on-cash return measures the investor's percentage return on the actual cash they put in, not whether the property covers its own debt. Cash flow is the simplest of the three, the raw dollar amount left over each month after every expense including the mortgage, while DSCR expresses that same relationship as a ratio lenders use to compare properties and set loan terms.

IONROI already tracks the numbers that feed into a DSCR calculation for residential portfolios, including rental income, operating expenses, and mortgage payments through the EMI schedule. IONROI doesn't currently generate a dedicated DSCR report formatted for lender submission, since DSCR is used mainly in commercial and larger investment property underwriting rather than day-to-day residential portfolio tracking. If your lender asks for a DSCR figure, you can pull your property's income and mortgage numbers straight from your IONROI dashboard and calculate it in a few seconds using the formula above.

Frequently asked questions

What is a good DSCR for an investment property?: There's no single number that applies everywhere, but a DSCR of 1.20 to 1.25 is commonly cited as the minimum lenders look for on stabilized investment and commercial property loans, meaning the property earns 20 to 25% more than its annual loan payment. Riskier property types, such as single-tenant retail or office space with upcoming lease expirations, often need a higher DSCR, sometimes 1.30 or above, to get approved. A well-occupied residential rental or multifamily building with steady income can sometimes qualify at the lower end of that range. Always confirm the exact minimum with your specific lender, since it depends on the loan program, property type, and country.
How do you calculate DSCR?: Divide the property's annual Net Operating Income (NOI) by its Total Debt Service, which is the full annual mortgage payment covering both principal and interest. For example, a property with $150,000 in annual NOI and a $120,000 annual mortgage payment has a DSCR of 150,000 divided by 120,000, which equals 1.25. NOI itself is rental income minus operating expenses like maintenance, insurance, and management fees, calculated before any mortgage payments are deducted. IONROI tracks rental income, operating expenses, and EMI payments separately, so you can pull both numbers you need for this calculation directly from your dashboard.
What is the difference between DSCR and cash-on-cash return?: DSCR measures whether a property's own income is enough to cover its loan payment, and lenders use it to decide whether to approve financing in the first place. Cash-on-cash return measures the investor's personal return on the actual cash they put into the deal, expressed as a percentage of income after all expenses including the mortgage. A property can have a healthy DSCR of 1.30 that satisfies the lender while still delivering a modest cash-on-cash return for the investor, because the two ratios use different denominators and answer different questions. DSCR protects the lender's risk; cash-on-cash return tells the investor whether the deal is actually worth their cash.
