How to Calculate Cash Flow on a Rental Property

Understanding a rental property’s cash flow is crucial for evaluating its financial viability. Cash flow represents the net money moving into and out of an investment. For real estate, this means the funds remaining from rental income after all property-related expenses are paid. This metric provides a clear picture of whether a property generates a surplus of funds or requires additional capital from the owner.

Identifying Rental Property Income

A rental property generates income from various sources, with monthly rent payments forming the largest component. The rent amount is established through the lease agreement and collected regularly from tenants. Other charges also contribute to the property’s overall income.

Late fees are applied when rent payments are not received by the due date. These fees can be a fixed amount, often ranging from $25 to $100, or a percentage of the monthly rent, commonly between 3% and 10%. Application fees are non-refundable charges collected from prospective tenants to cover administrative costs like background checks and credit reports. These fees typically range from $25 to $75 per applicant.

Additional income streams include pet fees or pet rent. Pet fees might be a one-time payment, ranging from $100 to $500, while pet rent is a recurring monthly charge, typically between $10 and $75 per month. Some properties also generate revenue from shared amenities like laundry facilities or vending machines, or from rented storage units and parking spaces.

Cataloging Rental Property Expenses

Owning and operating a rental property involves various expenses. A significant recurring expense is the mortgage payment, which consists of both principal and interest. For cash flow analysis, the interest portion is considered an expense, while the principal payment reduces the loan balance and builds equity.

Property taxes are annual levies imposed by local governments based on the property’s assessed value. These rates can range from under 0.5% to over 2% of the property’s value annually. Property insurance, specifically landlord insurance, protects against perils like fire, theft, and liability, typically costing between $800 and $3,000 annually. Homeowners Association (HOA) fees apply to properties within an HOA and cover shared amenities and common area maintenance, with average monthly fees ranging from $170 to $293.

Maintenance and repairs are ongoing costs for property upkeep, such as plumbing fixes or appliance repairs. Budgeting 1% to 2% of the property’s value annually or 5-8% of total gross rent is a common guideline. Utilities, if paid by the owner, include water, sewer, trash, electricity, and gas. Property management fees, if a professional manager is employed, typically range from 8% to 12% of the monthly rent collected.

Vacancy costs represent lost rent during periods when the property is unoccupied. Budgeting for a vacancy rate of 5% to 10% of gross potential rent is common. Advertising and marketing costs are incurred to attract new tenants. Legal and accounting fees cover services like lease agreement drafting, eviction assistance, or tax preparation, often ranging from $200 to $1,000 annually. Capital expenditure reserves are funds set aside for large, infrequent expenses that extend the property’s life or improve its value, such as roof replacements or HVAC system upgrades. Recommendations suggest setting aside 10% of annual income or 1% to 2% of the property’s value annually for these reserves.

Executing the Cash Flow Calculation

Calculating cash flow involves subtracting total expenses from total income. First, aggregate all income sources, including monthly rent, late fees, application fees, and pet rent. This sum represents the gross rental income for the period.

Next, compile all property-related expenses, as previously outlined.

The core formula for cash flow is: Total Income – Total Expenses = Cash Flow. For example, consider a property with a monthly rent of $1,500, late fees of $50, and pet rent of $25, resulting in a total monthly income of $1,575. If the monthly expenses include $600 for mortgage interest, $200 for property taxes, $100 for insurance, $150 for maintenance, $150 for property management, $75 for vacancy reserves, and $100 for capital expenditure reserves, the total monthly expenses would be $1,375. Subtracting total expenses ($1,375) from total income ($1,575) yields a positive cash flow of $200 for the month.

Interpreting Your Cash Flow Outcome

The cash flow calculation provides a clear financial snapshot of the rental property. A positive cash flow indicates that the property’s income exceeds its expenses, meaning money is left over after all operational costs are covered. This surplus can be reinvested, used for other financial goals, or serve as a buffer for unexpected costs.

Conversely, a negative cash flow signifies that the property’s expenses are greater than its income. In this scenario, the owner must contribute additional funds each month to cover the property’s operational deficit. A sustained negative cash flow can impact personal finances and may signal that the investment is not performing as expected.

Zero cash flow occurs when the property’s total income precisely matches its total expenses. While the property covers its own costs, it does not generate any surplus funds for the owner. Cash flow is a dynamic metric; it can fluctuate due to unexpected repairs, changes in market rental rates, or adjustments in property taxes and insurance premiums.
