Break-even rent is not fixed costs divided by one. Vacancy, management, and maintenance reserves are all **percentages of rent**, so they grow as the answer grows — which means the equation has to be solved, not guessed. • **Fixed Costs** = P&I + Property Tax + Insurance + HOA + Other fixed monthly costs • **Net Factor** = (1 − Vacancy%) × (1 − Management%) − Reserve% • **Break-Even Rent** = Fixed Costs ÷ Net Factor **Worked example:** **$1,340** of principal and interest, **$320** of property tax, **$130** of insurance and **$60** of other fixed costs is **$1,850** a month of fixed cost. With **6%** vacancy, **9%** management, and **8%** set aside for maintenance and capital reserves, the net factor is **0.7754**. Break-even rent is **$1,850 ÷ 0.7754 = $2,385.87** a month, or **$28,630.38** a year. Note how far that is above the fixed costs: **$536** a month of the rent never reaches the mortgage at all, because vacancy, management and reserves take their share first. At a market rent of **$2,600** the property clears break-even by **$214.13**, a **8.98%** margin, producing **$166.04** a month of cash flow after all three percentage costs. ## How to Use This Calculator: A $2,386 Break-Even Enter the fixed monthly costs first. **Principal and interest, property tax, insurance, HOA dues, and anything else that does not vary with rent** — a lawn service, a pest contract, an umbrella policy allocation. These do not shrink when the unit sits empty, which is exactly why they set the floor. Then set the three percentages, and set them honestly. **Vacancy at 6%** is roughly 22 days a year; **management at 9%** is a normal headline rate, though the [property management fee calculator](/calculators/property-management-fee-calculator) usually shows the effective rate is higher once leasing fees are counted; and **8% for maintenance and capital reserves** is a conservative-looking figure that in practice is closer to a minimum on an older property. Setting reserves to zero because the roof is currently fine is the most common way a break-even rent gets understated. The **net factor of 0.7754** is the useful intermediate number. It says that only 77.5 cents of each rent dollar is available to cover fixed costs. Everything below that line is why a property renting at exactly its mortgage payment loses money reliably and steadily. The **target rent** row solves the same equation for a chosen cash flow rather than zero. To clear **$200** a month, the rent needs to be **$2,643.80** — and note that it takes **$258** of extra rent to produce **$200** of extra cash flow, because management and reserves take a cut of the increase too. That ratio is worth remembering before assuming a rent rise translates dollar for dollar, which the [rent increase calculator](/calculators/rent-increase-calculator) shows from the other direction. ## A Second Example: Self-Managed, With HOA Dues Removing management changes the shape of the answer. Take **$980** of principal and interest, **$210** of tax, **$95** of insurance, **$250** of HOA dues, and **$25** of other costs — **$1,560** fixed — with **5%** vacancy, **no management fee** because you self-manage, and **10%** reserves. The net factor is **0.85** and break-even rent is **$1,835.29**. At a market rent of **$1,900** the margin is only **$64.71**, or **3.53%**, producing **$55.00** a month of cash flow. That is a property that works on paper and has essentially no room for error. The **break-even occupancy of 92.11%** makes the fragility concrete: the property can afford to sit empty for **28.8 days a year** and no more. One slow turnover consumes the entire year's cushion, and a single significant repair consumes more than a year of cash flow. The [vacancy rate and loss calculator](/calculators/vacancy-rate-loss-calculator) prices what those empty days actually cost. The **$250** of HOA dues is the item worth interrogating. It is **16%** of the fixed cost base and it will rise — dues are not a fixed cost in the long run, only in the short one. The [HOA fee impact calculator](/calculators/hoa-fee-impact-calculator) compounds them properly. And the zero management fee assumes you will always self-manage, which is an assumption about your future time rather than about the property. Add it back at 8% to 10% and break-even rent moves to roughly $2,000 — above the market rent, which is the honest answer to whether this deal works with a manager. ## Break-Even Rent, Break-Even Occupancy, and the 1% Screen **Break-even rent answers the pricing question**: what must this property earn to stop losing money? It is the right number to know before setting an asking rent, before agreeing a renewal, and before buying — because if the market rent in the area is below your break-even, no amount of good management fixes the deal. **Break-even occupancy answers the risk question**: how much can go wrong before the property stops covering itself? At **86.98%** in the first example the property can absorb 47 vacant days a year; at **92.11%** in the second it can absorb 29. That single number tells you more about the fragility of a rental than the cash flow figure does, because cash flow looks the same whether it comes with a large cushion or none. **Neither is the same as the 1% rule.** That screen — monthly rent of at least 1% of purchase price — ignores financing entirely, which means it is useless for comparing a property bought at 25% down against the same property bought at 5% down. Break-even rent uses your actual debt service and is therefore specific to your deal rather than to the building. **A break-even property is not necessarily a bad investment.** It still accrues principal repayment every month, may appreciate, and generates depreciation deductions. But it produces no cushion, and a rental with no cushion is a rental where every unexpected repair comes out of your own income. Carry the numbers through the [property cash flow calculator](/calculators/property-cash-flow-calculator) for the monthly picture and the [rental property ROI calculator](/calculators/rental-property-roi-calculator) for total return before deciding that break-even is enough. ## Limitations This calculator solves a steady-state equation and assumes your percentage inputs are accurate. They usually are not, and they usually err the same way: vacancy set below what the market actually experiences, management omitted because you self-manage today, and reserves set from recent repair history rather than from the age of the roof, the furnace, and the water heater. Under-setting any of the three understates break-even rent, which is the specific failure this page exists to prevent. It treats maintenance and capital reserves as a percentage of rent, which is a convention rather than a fact. Capital costs track the age and condition of the building, not the rent it commands, and a percentage-based reserve on a low-rent older property will be badly short. Where you have a component-based reserve estimate, convert it to a monthly figure and enter it as a fixed cost instead. The model is pre-tax and single-period. It excludes depreciation and its tax shelter, the principal portion of the mortgage payment that is building equity rather than disappearing, appreciation, rent growth, expense inflation, and the eventual sale — so a property at break-even is not necessarily an investment at break-even. It also assumes a fixed mortgage payment; on an adjustable loan, break-even rent moves at every reset. This is a general educational tool, not investment advice — verify assumptions against real operating data and consult a qualified professional before committing. ## Related Calculators Set the percentage inputs from real figures rather than habit: the [Vacancy Rate & Loss Calculator](/calculators/vacancy-rate-loss-calculator) prices vacancy in days rather than a rule of thumb, and the [Property Management Fee Calculator](/calculators/property-management-fee-calculator) shows the effective management rate once leasing fees are included. On a condo, the [HOA Fee Impact Calculator](/calculators/hoa-fee-impact-calculator) compounds dues that are only fixed in the short run. Then carry the result into the [Property Cash Flow Calculator](/calculators/property-cash-flow-calculator) for the monthly view and the [Rental Property ROI Calculator](/calculators/rental-property-roi-calculator) for total return, and use the [Rent Increase Calculator](/calculators/rent-increase-calculator) when a renewal needs to close a gap. ## Frequently asked questions ### How do you calculate break-even rent? Divide fixed monthly costs by a net factor that accounts for the percentage costs: Net Factor = (1 − Vacancy%) × (1 − Management%) − Reserve%. With $1,850 of fixed costs, 6% vacancy, 9% management and 8% reserves, the factor is 0.7754 and break-even rent is $2,385.87. ### Why is break-even rent higher than the mortgage payment? Because vacancy, management, and reserves take their share of rent before the mortgage does. In the worked example, $536 a month of a $2,386 rent never reaches the fixed costs at all. A property renting at exactly its mortgage payment loses money reliably. ### What is break-even occupancy? The occupancy rate at which a property exactly covers itself at a given rent. At 86.98%, the property can sit empty 47 days a year; at 92.11% it can absorb only 29. It tells you more about a rental's fragility than the cash flow figure does, because equal cash flow can come with very different cushions. ### How much should I set aside for maintenance and capital reserves? Eight to ten percent of rent is a common planning figure and closer to a minimum on an older property. Capital costs track the building's age rather than its rent, so where you have a component-based estimate — roof, furnace, water heater by remaining life — use that as a fixed monthly figure instead. ### Should I include a management fee if I self-manage? Yes, unless you are certain you will always self-manage. In the second example, adding management back at 8% to 10% moves break-even rent from $1,835 to roughly $2,000 — above the market rent, which is the honest answer to whether that deal works with a manager rather than with your own unpaid time. ### How much extra rent do I need for $200 of cash flow? More than $200. Management and reserves take a share of any increase too, so on the worked example it takes $258 of extra rent to produce $200 of extra cash flow — the rent goes from $2,385.87 to $2,643.80. ### Is break-even rent the same as the 1% rule? No. The 1% screen compares rent to purchase price and ignores financing entirely, so it gives the same answer whether you put 5% or 25% down. Break-even rent uses your actual debt service and is specific to your deal rather than to the building. ### Is a property at break-even worth owning? It can be. Principal repayment builds equity every month, appreciation may follow, and depreciation shelters income. But it produces no cushion, so every unexpected repair comes from your own income rather than the property's — and one significant repair can consume more than a year of cash flow. ## Related concepts - **Net Factor** — The share of each rent dollar left after vacancy, management, and reserves.
