How is DSCR calculated?
Divide the cash flow available for debt payments by total annual debt payments. Cash flow usually starts with net income, then adds back non-cash expenses like depreciation and amortization plus interest expense. Debt payments include principal and interest on every loan, line, lease and financing arrangement, including the proposed new loan.
The basic formula:
- Cash flow available: net income + depreciation + amortization + interest expense (plus accepted adjustments).
- Annual debt service: all principal and interest payments due over twelve months.
- DSCR: cash flow available divided by annual debt service.
What does a worked example look like?
Here is a simple illustration using round, hypothetical numbers. A distributor reports net income of 300,000 dollars, with 80,000 dollars of depreciation and 40,000 dollars of interest expense, giving cash flow available of 420,000 dollars. Existing annual payments total 200,000 dollars, and the proposed term loan adds 100,000 dollars per year.
Total debt service would be 300,000 dollars. Dividing 420,000 by 300,000 gives a DSCR of 1.4x. That means the business generates about 1.40 dollars of cash for every dollar of debt payments. This is only an example; your funder's calculation may include different adjustments.
If the same company requested a larger loan adding 200,000 dollars a year, total debt service would be 400,000 dollars and DSCR would fall to about 1.05x, leaving very little room for a slow quarter.
What ratio do funders look for?
There is no single number. Many funders typically want comfortable headroom above 1.0x so the business can absorb a slower season, a lost customer or rising costs. Some cite targets around 1.25x, but it varies by funder, product, industry and collateral. A strong ratio alone does not decide the loan.
Underwriters also consider how stable the cash flow is. A company with long-term contracts and steady margins may be comfortable at a lower ratio than one whose earnings swing widely. Collateral, owner strength and credit history can also offset a tighter ratio.
What is global debt service coverage?
Global DSCR combines the business's cash flow and debts with the owners' personal income and obligations, such as mortgages and personal loans. Funders use it when owners guarantee the loan and business and personal finances are closely connected. A healthy business ratio can weaken if owners carry heavy personal debt.
This is why personal tax returns and personal financial statements are often requested. If an owner draws large distributions to cover personal obligations, the global picture reflects that. Our documents checklist covers what owners typically provide.
Which cash flow figure do underwriters use?
Most underwriters start with tax returns and financial statements for the most recent full years, sometimes averaging several years or weighting the latest year. Year-to-date results help show the current trend. They add back non-cash items and may adjust for documented one-time expenses or above-market owner compensation.
Not every add-back is accepted. Underwriters generally accept items clearly supported by documents and question aggressive adjustments. Distributions to owners may be deducted if they are needed for personal obligations. See how lenders read business tax returns.
What if your DSCR is below a funder's target?
You have options. Request a smaller amount or a longer term to reduce the annual payment, add collateral, show strong year-to-date improvement, or lower existing payments by moving recurring swings to an appropriately sized line. Sometimes the answer is waiting until a stronger year is documented before applying.
A longer-term term loan or equipment financing spread over the asset's useful life can reduce annual debt service meaningfully. If you want help seeing which structure your numbers support, start an application with 1Prime Capital.
Frequently asked questions
Does the new loan's payment count in the calculation?
Yes. Underwriters calculate DSCR on a pro forma basis, meaning they add the proposed loan's annual payments to your existing debt service. That shows whether cash flow can carry everything after the new loan closes, which is the question the funder needs answered.
Do credit line balances count as debt service?
Usually, though funders treat them differently. Some use the actual interest paid, while others assume a payment based on the full line or the drawn balance. Ask how a funder handles revolving lines, since it can change your ratio noticeably.
Can a strong DSCR make up for weaker credit?
It can help. Strong, stable cash flow is one of the most persuasive factors in underwriting and may offset a thinner credit file or limited collateral. It does not override serious recent credit problems, and most business loans still include personal guarantees.
How do leases affect DSCR?
Equipment and vehicle leases are commonly treated as fixed obligations and included in debt service or adjusted in the calculation. Real estate rent is often handled as an operating expense. Treatment varies by funder, so list every lease on your debt schedule.
Should I calculate my own DSCR before applying?
It is a smart step. A rough calculation shows whether your request is realistic and how much payment your cash flow supports. Your CPA can help identify supportable add-backs. Underwriters will do their own calculation, but you will know what to expect.
