In hospital financials and Revenue Cycle Management (RCM), Gross Daily Revenue (often referred to as Average Daily Gross Revenue or ADGR) is a foundational metric used primarily to measure billing volume and to calculate other key performance indicators (KPIs), most notably Days in Accounts Receivable (A/R).

It represents the average daily dollar amount of services billed to patients and payers, based on the hospital’s chargemaster rates (list prices) before any insurance adjustments or contractual allowances are applied.

1. How to Calculate Gross Daily Revenue

To obtain this figure, you analyze the total gross charges posted over a specific lookback period (commonly 90, 180, or 365 days) to smooth out daily fluctuations caused by weekends or holidays.

• Example: If a hospital posted $50,000,000 in gross charges over the last 90 days:

$50,000,000 / 90 = $555,555 per day

 

2. Primary Application: Days in A/R

The most critical use of Gross Daily Revenue is as the denominator in the Days in Accounts Receivable formula. This KPI measures the average time it takes the hospital to be paid.

• Why it matters: If your Total A/R is $25,000,000 and your Gross Daily Revenue is $555,555, your Days in A/R is roughly 45 days.
• Benchmark: A lower number indicates a more efficient revenue cycle. Ideally, hospitals aim for roughly 30–40 days, though this varies by payer mix.

 

3. Gross vs. Net Daily Revenue

It is vital to distinguish between Gross and Net daily revenue, as they serve different financial purposes:

Feature	Gross Daily Revenue	Net Daily Revenue
Basis	Chargemaster (List Price)	Actual Expected Reimbursement
Formula	Total Charges / Days	(Total Charges – Contractual Allowances) / Days
Use Case	Measuring billing volume and AR Days.	Measuring actual cash flow and liquidity.
Financial Reality	Inflated (does not reflect cash collected).	Realistic (reflects cash expected).

4. Strategic Significance

While Gross Daily Revenue does not equal cash in the bank, tracking it is essential for:

• Volume Trending: A sudden drop in Gross Daily Revenue often points to issues upstream, such as a decline in patient volume, a failure in charge capture (missing charges), or a credentialing issue preventing billing.
• Staffing Ratios: Revenue cycle leaders often use gross charges to determine staffing needs for coding and billing departments.

Summary

Gross Daily Revenue is a measure of production, not collection. It tells you how much work the facility is generating in billable terms, but it must be paired with the Net Collection Rate to understand the actual financial health of the organization
