Break-Even Rent Calculator
A break-even rent calculator estimates the monthly rent needed to cover operating expenses and debt service after vacancy. It helps pressure-test rent assumptions, but it does not verify market rent, tenant demand, repairs, or future cost changes.
Estimates are based on your inputs and assumptions. DealSharp does not provide financial, investment, legal, tax, or lending advice.
Run the number, then pressure-test the assumptions.

Use this working calculator as a starting point, then run the full deal in DealSharp when you need more inputs, side-by-side scenarios, and risk context.
Break-even rent = (monthly operating expenses + monthly debt service) / (1 - vacancy rate)
If monthly expenses are $800, debt service is $1,400, and vacancy is 5%, estimated break-even rent is about $2,316.

How to read this number
The useful move is not treating one number as a final answer. Use it to decide which assumptions deserve more review, then compare the result against cash flow, financing, reserves, repair risk, and your own constraints.
Inputs required
- Monthly operating expenses.
- Monthly debt service.
- Vacancy rate used to adjust collected rent.
Outputs explained
- Estimated break-even rent.
- Rent level needed before modeled cash flow turns positive.
- Context for comparing listed rent to required rent.
Assumptions to review
- Operating expenses and debt service are entered monthly.
- Vacancy is modeled as a percentage of potential rent.
- The calculator does not validate rent comps or lease-up risk.
What this tells you
- Break-even rent shows the rent level needed to cover modeled monthly costs.
- It can help spot thin cash-flow scenarios before making a deeper model.
- It is useful beside rental cash flow, operating expense, and vacancy analysis.
What this does not tell you
- It does not prove the market can support that rent.
- It can understate risk if repairs, CapEx, management, taxes, or insurance are missing.
Common mistakes
- Ignoring vacancy in the break-even rent calculation.
- Using mortgage payment only and excluding operating expenses.
- Assuming asking rent equals achievable rent.
FAQ
Is break-even rent the same as market rent?
No. Break-even rent is a cost threshold. Market rent depends on comparable rentals, condition, location, and tenant demand.
Should reserves be included?
Many investors include repair and CapEx reserves so the break-even estimate does not depend on a best-case month.
