How to Calculate Apartment Turnover Rate
Apartment turnover rate is a critical Key Performance Indicator (KPI) for property managers and real estate investors. It measures the percentage of residents who move out of a property during a specific period, typically one year. Understanding this metric helps in budgeting for vacancy losses, marketing expenses, and unit preparation costs.
The Formula
The standard formula for calculating apartment turnover rate is simple:
(Number of Move-Outs / Total Number of Units) × 100 = Turnover Rate %
Example: If you manage a complex with 200 units and you had 90 move-outs over the last 12 months:
(90 ÷ 200) = 0.45
0.45 × 100 = 45% Turnover Rate
Why Turnover Rate Matters
A high turnover rate is expensive. Every time a resident leaves, the property incurs costs that directly impact Net Operating Income (NOI). These costs include:
Vacancy Loss: Rent not collected while the unit sits empty.
Make-Ready Costs: Cleaning, painting, carpet replacement, and repairs required to prepare the unit for the next tenant.
Marketing Expenses: Advertising fees, leasing commissions, and the time spent by staff showing the unit.
Administrative Costs: Processing applications, screening tenants, and drafting leases.
What is a "Good" Turnover Rate?
While averages vary by location and property class, the national average for apartment turnover in the United States generally hovers between 45% and 50%.
Below 40%: Indicates strong resident retention. This is ideal for maximizing profitability.
45% – 50%: Industry average.
Above 55%: Suggests potential issues. If your rate is this high, consider evaluating your renewal incentives, maintenance response times, or rental pricing strategy.
Tips to Reduce Turnover
Improving your turnover rate (lowering the percentage) is often more cost-effective than finding new tenants. Strategies include:
Responsive Maintenance: Fix issues quickly to keep residents happy.
Renewal Incentives: Offer small upgrades (e.g., carpet cleaning or a smart thermostat) upon lease renewal.
Community Building: Host events to create a sense of community, making it harder for residents to leave emotionally.
Fair Pricing: Ensure rent increases are reasonable and match the market value.
