The theory

Understanding Operating Expenses.

Operating expenses are the costs incurred to keep your rental property running, excluding mortgage payments (principal and interest). The Operating Expense Ratio (OER) is a key metric that shows what percentage of your gross revenue is spent on expenses.

/ Formula

A lower OER generally indicates better profitability and financial efficiency. For short-term rentals, a typical OER can range from 30% to 50%, depending on the level of service and management.

OER = (Total Operating Expenses / Gross Revenue) × 100
Questions, answered

Frequently asked questions.

Net Operating Income is your gross revenue minus your operating expenses. It's a measure of a property's profitability before considering debt service (mortgage) and income taxes. A higher NOI is better.
No, mortgage payments (both principal and interest) are considered a financing cost, not an operating expense. This calculator focuses on the operational efficiency of the property itself, independent of how it's financed.
A good OER for a short-term rental is typically between 30% and 50% of gross revenue. Self-managed properties often have lower ratios (30-40%), while properties using full-service management might be in the 40-50% range or higher.
Focus on the largest expense categories first. Common strategies include: shopping around for better insurance rates, appealing property taxes, performing preventative maintenance to avoid costly repairs, and buying supplies in bulk. If you self-manage, you can save significantly on management fees.
No, this calculator is for ongoing operating expenses. Initial setup costs like furniture, renovations, and initial deep cleaning are considered capital expenditures (CapEx) and should be analyzed separately as part of your overall investment return.
