STR Profitability Ratios That Reveal Your Real Margin

Most STR operators know their revenue. Fewer know exactly where profit is being created—or lost.

That's the difference between tracking revenue and tracking profitability.

The most effective way to measure profitability is through a handful of financial ratios that reveal how efficiently your operation converts revenue into margin. Four metrics stand out: Revenue per Property, Fees-to-Rent Ratio, Cleaning Margin, and Operator NOI Margin.

Portfolio Revenue Doesn't Tell the Whole Story

A portfolio can look healthy while individual properties underperform.

Strong portfolio averages often mask units that consistently drag down profitability. That's why property-level reporting matters. While portfolio numbers show the outcome, property-level metrics reveal what's driving it.

Averages tell you what happened. Segmentation and ratio metrics tell you why. Here are 4 metrics you can use to better understand your performance:

1. Revenue per Property

Formula: Total Revenue ÷ Number of Properties

Revenue per Property measures the revenue contribution of each unit in your portfolio.

If total revenue is growing because you're adding properties while Revenue per Property remains flat, you're scaling volume—not performance.

Monitor year-over-year trends and investigate large gaps between top- and bottom-performing properties. Those gaps often point to pricing, marketing, or operational issues that can be addressed.

2. Fees-to-Rent Ratio

Formula: Total Fees ÷ Gross Rent

This ratio measures the relationship between management fees and rental income.

For commission-based STR management models, a healthy range is typically 18% to 28%.

A lower ratio may indicate outdated pricing, increasing operating costs, or a fee structure that no longer reflects the value you're delivering.

Small adjustments can make a significant impact. On $2 million in annual managed rent, a 1% fee increase represents an additional $20,000 in revenue.

3. Cleaning Margin

Formula: (Cleaning Revenue − Cleaning Cost) ÷ Cleaning Revenue

Cleaning Margin is one of the most overlooked profit drivers in STR operations.

Healthy margins generally fall between 10% and 20% or higher. If cleaning costs regularly exceed collected fees, you're subsidizing guest turnovers with management revenue.

Review cleaning fees against vendor invoices on a regular basis and flag properties where cleaning costs consistently erode profitability.

Many operators don't realize their cleaning margin is negative until they calculate it.

4. Operator NOI Margin

Formula: NOI ÷ Operator Gross Revenue

Operator NOI Margin measures how much revenue ultimately remains as net operating income.

For commission-based management companies, healthy margins typically range from 25% to 50%, depending on the operating model.

If revenue is growing but profit isn't, this ratio helps identify whether labor, software, vendor costs, or other expenses are absorbing the gains.

A growing top line doesn't always mean a healthier business. NOI Margin reveals whether growth is actually translating into profit.

None of This Works Without Clean Books

These ratios are only as accurate as the financial data behind them.

Common issues include misclassified expenses, owner-funded costs mixed into operating accounts, inconsistent fee categorization, and revenue grouped into catch-all accounts that provide little visibility.

When financial data is inaccurate, ratios become misleading. When ratios are misleading, decision-making suffers.

Before benchmarking performance, ensure your chart of accounts, expense categorization, trust accounting, and monthly close processes are consistent and reliable.

What to Do Next

Pull the last three months of financial data and calculate these four ratios:

• Revenue per Property

• Fees-to-Rent Ratio

• Cleaning Margin

• Operator NOI Margin

Most importantly, calculate them at the property level—not just across the portfolio.

If you can't easily produce these numbers, that's often a sign your reporting structure needs attention.
