How to Calculate Breakeven Occupancy for Multifamily Properties

When underwriting a multifamily property, it's easy to get caught up in upside potential: rent growth, value-add opportunities, and projected returns. But savvy investors know that understanding the downside risk is just as important. One of the best metrics for quantifying this risk is the Breakeven Occupancy Rate. It answers a simple but vital question: "What is the minimum occupancy needed for the property to pay all of its bills?" This guide will walk you through the breakeven occupancy formula, show you how to calculate it, and explain why it's a must-have tool in your analysis toolkit.

What is Breakeven Occupancy?

Breakeven Occupancy is the occupancy level at which a property's total income equals its total expenses. At this point, the property is neither making money nor losing money; its cash flow is zero. Any occupancy percentage above the breakeven point results in positive cash flow, while any percentage below it results in a net loss, requiring the owner to inject capital to cover the shortfall.

It's a critical stress-test metric. Knowing your breakeven point tells you exactly how much vacancy your property can withstand before it gets into financial trouble.

The Breakeven Occupancy Formula

The formula for calculating breakeven occupancy is straightforward. You sum up all the fixed and variable costs and divide them by the property's maximum potential income.

Let's define the components:

• Operating Expenses (OpEx): All costs to run the property, including taxes, insurance, utilities, repairs, and management fees.
• Annual Debt Service: The total of all mortgage payments (principal and interest) over one year.
• Gross Potential Income (GPI): The total annual income the property would generate if it were 100% occupied at market rents, including other income sources like laundry or parking.

Step-by-Step Breakeven Occupancy Calculation

Let's calculate the breakeven point for a 50-unit apartment building.

Property Financials:

• Gross Potential Income (GPI): $600,000
• Total Operating Expenses (OpEx): $240,000 (40% of GPI)
• Annual Debt Service: $210,000

Step 1: Sum the Total Expenses.

This includes everything required to keep the lights on and pay the bank.

$240,000 (OpEx) + $210,000 (Debt Service) = $450,000 (Total Expenses)

Step 2: Divide Total Expenses by Gross Potential Income.

This tells you what percentage of your total potential income is consumed by costs.

$450,000 (Total Expenses) / $600,000 (GPI) = 0.75

Step 3: Convert to a Percentage.

0.75 × 100 = 75%

The Breakeven Occupancy for this property is 75%. This means that as long as 75% or more of the units are occupied and paying rent, the property will generate enough income to cover all its expenses. The income from the remaining 25% of units is the owner's profit. For another risk perspective, see our DSCR calculator guide and learn about analyzing multifamily properties.

What is a "Safe" Breakeven Occupancy Percentage?

A lower breakeven occupancy is always better, as it signifies a larger margin of safety. While there's no universal standard, here are some general guidelines for multifamily properties:

If your analysis reveals a breakeven point over 85%, it's a red flag. You should re-evaluate your assumptions. Is the purchase price too high? Are the operating expenses out of control? Is the proposed loan too large?

How to Lower Your Breakeven Occupancy

If you want to de-risk a project, focus on lowering its breakeven point. You can do this by:

1. Reducing Expenses: Lowering either your operating expenses (e.g., through better management, utility conservation) or your debt service (e.g., by making a larger down payment or refinancing to a lower rate).
2. Increasing Income: Raising the Gross Potential Income by increasing rents to market levels or adding new revenue streams.
