Maximum annual debt service coverage compares defined annual income with the largest annual payment requirement in a debt schedule. Work through the income bridge, identify the peak year, and reconcile the result against first scheduled-year coverage.
Maximum annual debt service coverage ratio compares defined annual income available for repayment with the largest annual debt-service requirement in a specified schedule. The word maximum belongs to the payment denominator. It does not describe a ceiling on an acceptable ratio.
Maximum annual debt service coverage ratio = Defined annual income available for debt service / Maximum annual debt service
Maximum annual debt service = Largest included annual total of principal and interest
This measure is often abbreviated as MADS coverage. It asks how a stated annual income amount compares with the heaviest included repayment year, even when that year lies ahead. The numerator might be historical income rather than income forecast for the peak year, so label the basis clearly.
For a real reporting example, Baylor Scott & White Health's annual disclosure, printed page 24, presents historical coverage of actual annual debt service separately from historical coverage of maximum annual debt service. Its definition takes the largest total annual requirement in the current or any succeeding fiscal year. That is an issuer-specific reporting example, not a definition to substitute into another organization's agreement.
The ordinary DSCR calculation compares income with the debt service for its stated period. Keep that label separate so a change in denominator does not masquerade as an earnings change.
Use the relevant agreement's definition of income or net revenues available for repayment. It may differ from net income, EBITDA, or operating cash flow. The Texas Water Development Board's debt-service coverage guidance specifically instructs borrowers to consult their covenants or loan agreement for the net-revenue definition, including which revenues and expenses are included or excluded.
For the worked example, a US equipment-services company uses operating revenue less operating expenses, with included depreciation added back. Assume its agreed preparation convention permits that addback and that no restricted revenue, unusual gain, or additional adjustment is present.
| Annual income bridge | Calculation | Amount (USD) |
|---|---|---|
| Operating revenue | Source P&L total | 9,500,000 |
| Operating expenses, including depreciation | Source P&L total | -6,750,000 |
| Operating income | 9,500,000 - 6,750,000 | 2,750,000 |
| Permitted depreciation addback | Included in expenses above | 250,000 |
| Income available for debt service | 2,750,000 + 250,000 | 3,000,000 |
The expenses in this example exclude interest, so interest is not added back again. If your source starts with a different profit line, rebuild the bridge rather than copying its adjustment labels. Keep the source account reference beside each amount so a reviewer can verify inclusion once.
This numerator is an agreed preparation measure. It is distinct from cash debt coverage, which compares operating cash flow with an average balance-sheet obligation measure.
Start with one row per required payment. Include obligation identifier, due date, principal, interest, currency, and agreement scope. Aggregate the payments into the fiscal years required by the reporting convention. A calendar-year company uses years ending December 31 in this example.
Assume the schedule below contains all remaining included obligations and no payments after 2031. The company has already confirmed the scope and treatment of each obligation; this example does not assume automatic refinancing of a future payment.
| Fiscal year | Principal (USD) | Interest (USD) | Annual debt service (USD) |
|---|---|---|---|
| 2027 | 900,000 | 600,000 | 1,500,000 |
| 2028 | 1,100,000 | 550,000 | 1,650,000 |
| 2029 | 1,500,000 | 500,000 | 2,000,000 |
| 2030 | 1,200,000 | 450,000 | 1,650,000 |
| 2031 | 1,100,000 | 400,000 | 1,500,000 |
In a spreadsheet, principal is column B, interest column C, and the annual total column D. Put =B2+C2 in D2 and fill down. The denominator is:
=MAX(D2:D6)
That returns $2,000,000, the total due in 2029. Select the maximum after combining each year's components. Taking principal from one year and interest from another constructs a payment requirement that does not belong to the schedule.
If the business needs an SBA-specific preparation file, use the separate SBA coverage input guide. This article's illustrative income bridge does not establish an SBA underwriting convention.
With income available of $3,000,000 and maximum annual service of $2,000,000, coverage is 1.50 times. Hold unrounded inputs and display ratios to two decimals.
| Test | Calculation | Result |
|---|---|---|
| First scheduled-year coverage, 2027 | 3,000,000 / 1,500,000 | 2.00 times |
| Maximum annual coverage | 3,000,000 / 2,000,000 | 1.50 times |
| Income above maximum service (USD) | 3,000,000 - 2,000,000 | 1,000,000 |
| Reconstruction of income (USD) | 1.50 × 2,000,000 | 3,000,000 |
The reconstruction must recover the numerator. Separately, confirm that the peak annual total equals its principal plus interest and that no other included year exceeds it. Those checks prove the arithmetic, while a payment-by-payment reconciliation proves the schedule is complete.
First scheduled-year coverage looks stronger because that year's payment burden is smaller. Neither result proves the business will generate the same income in 2029. Where future operating changes matter, project-finance DSCR addresses matching projected cash available and debt service across periods.
Suppose the 2029 principal payment rises to $1,900,000, with every other input unchanged. Interest remains $500,000, so that year's annual service becomes $2,400,000.
| Peak-year comparison | Original | Revised |
|---|---|---|
| Principal (USD) | 1,500,000 | 1,900,000 |
| Interest (USD) | 500,000 | 500,000 |
| Maximum annual service (USD) | 2,000,000 | 2,400,000 |
| Income available (USD) | 3,000,000 | 3,000,000 |
| Maximum annual coverage | 1.50 times | 1.25 times |
| Income above maximum service (USD) | 1,000,000 | 600,000 |
The revised ratio falls solely because the peak obligation increased. First scheduled-year coverage remains 2.00 times. That separation is useful when explaining a refinancing proposal or a revised amortization schedule to the business's finance team.

No. Maximum refers to the largest annual debt-service obligation included in the calculation. The ratio tests annual income against that peak payment requirement. Any required minimum coverage is a separate condition specified by the applicable agreement or reporting framework.
First add principal and interest within each included year, then select the largest annual total. Combining the largest components from different years can create a payment obligation that never occurs and overstate the denominator.
Only when the current year's debt service equals the relevant maximum annual amount and the numerator definitions match. Otherwise, current-year coverage measures that year's payment burden, while maximum annual coverage compares the numerator with the schedule's peak burden.
