Break even rent calculator

Cover costs before looking for a return

Break-even rent is the scheduled monthly rent needed to cover the costs you enter. It is useful when comparing a rental estimate with a known mortgage payment and a realistic operating budget. A result below an advertised rent does not establish profitability: it simply means the entered costs fit within that rent under the stated maintenance and vacancy assumptions.

Enter mortgage principal and interest for one month. Property tax and insurance are entered for a full year, then divided by twelve. HOA means homeowners association fees and uses a monthly amount. If an escrow payment already includes tax or insurance, separate those amounts before entering them again. Counting a bill twice makes the required rent too high.

Maintenance and vacancy both use scheduled gross rent as their base. For example, two separate five percent allowances leave ninety percent available to pay fixed costs. The formula must include both percentages. Dividing by one minus vacancy alone would omit the maintenance input and understate the result.

Keep the two allowances consistent

The result is an average over the year, not a promise that each calendar month pays for itself. Vacancy represents rent not collected because the property is empty. Maintenance represents an allowance for ongoing upkeep. This model deliberately uses the same scheduled-rent base for both, so the two percentages are added before calculating the retained share.

Maintenance plus vacancy must remain below one hundred percent: at that point there is no retained rental income available for fixed costs.

If all fixed costs are zero, the result is zero under the entered assumptions. It does not suggest that a real property has no expenses. Check whether the budget omits repairs, management, utilities or a planned replacement before using that number.

What this US comparison does not include

The output is a cash-cost comparison before income tax. It also excludes capital expenditure and any cost not entered. Mortgage principal is a cash payment, even though its tax treatment differs from a deductible rental expense. Depreciation is not entered because it is not a monthly cash bill. The IRS rental-property guidance linked below provides tax context; it does not prescribe a maintenance percentage, vacancy allowance or asking rent.

There are no inputs for acquisition costs, selling costs, appreciation or an investment return target. The calculator therefore cannot estimate a property's lifetime return or set a minimum acceptable profit. It also does not convert a budget into a legally permitted rent increase. Applicable rental agreements and state or local restrictions need their own review.

Compare the result with rent quoted for a complete month on the same property and with the same inclusions. A furnished or utilities-inclusive quote may not be comparable with a rent figure whose expenses exclude those services.

Review the budget before acting

Ask a property manager about realistic vacancy and maintenance expectations for the specific property. Use your lender's repayment figure and current bills. Irregular costs can be converted into a monthly budget outside this tool, but do not enter a monthly figure into an annual tax or insurance field.

Speak with an accountant about deductibility and a qualified local advisor if rent restrictions affect the decision. Recalculate when a mortgage rate resets, an insurance renewal changes or an association levy is agreed. A dated cost estimate is more useful than a precise-looking result built from old or incomplete inputs.
