Calculate the Rent This Property Needs
Find the break-even rent — the amount that covers every cost with nothing to spare — and see how much cushion your expected rent leaves above it. Then set a cash-flow target and see the rent it takes to get there.
The rent this property needs
The monthly rent at which cash flow is exactly zero — every dollar of rent covers a dollar of cost, with nothing left over.
Your margin of safety
Your rent sits $431/mo above break-even — that's the buffer that absorbs a bad month before you're paying out of pocket.
Rent for a cash-flow target
The rent you'd need to hit a monthly cash flow you choose.
Your margin of safety, in one number
Every rental has a rent floor — the point where income exactly meets cost. Knowing it turns a vague sense of risk into a concrete buffer: if the going rent is $2,400 and break-even is $1,900, you have $500 a month of room before the property costs you money.
The gap between market rent and break-even is your safety margin. A wide gap survives vacancies and repairs; a narrow one is fragile. When you're ready for the complete picture — returns, financing, and a verdict — run the full analysis.
Frequently asked questions
What is break-even rent?
Break-even rent is the monthly rent at which cash flow is exactly zero — every dollar of rent covers a dollar of cost (mortgage, taxes, insurance, vacancy, maintenance, and reserves), with nothing left over. Below it the property loses money; above it, the surplus is your cash flow.
Why does break-even rent matter?
It's a margin-of-safety check. If market rent sits comfortably above break-even, you can absorb a bad month or an unexpected repair. If it's close, small changes in vacancy or expenses can tip you into the red. It turns 'this seems fine' into a concrete threshold.
How is break-even rent calculated?
Start from all the property's costs — mortgage, taxes, insurance, HOA — plus the rent-linked costs (vacancy, management, maintenance, CapEx). The break-even rent is the amount that makes total income equal total cost. This calculator solves it for you and lets you set a cash-flow target instead of zero.
What's the difference between break-even rent and break-even occupancy?
Break-even rent asks 'how much rent do I need?' at full occupancy. Break-even occupancy asks 'how full does it need to stay?' at the current rent — the share of gross rent required to cover every cost. They're two views of the same safety margin; this calculator shows both.
Should I buy if market rent is just above break-even?
A thin margin is a warning sign, not an automatic no. It means the deal depends on everything going right — low vacancy, controlled expenses, no surprises. Many investors want rent well above break-even, or a lower purchase price, before committing. Run the full analysis for the complete picture.
