Rental Property Maintenance Budget Calculator

How much should a landlord budget for maintenance?

Three commonly-used rules of thumb produce defensible maintenance reserve estimates: the 1 percent rule (1 percent of property value per year), the $1 per square foot rule, and the percent-of-rent rule (5 to 10 percent of monthly rent). All three are approximations. Real maintenance spend depends on property age, build quality, tenant behavior, and how proactive the operator is.

The 1% rule vs the 50% rule

The 1 percent rule estimates maintenance alone (cleaning, repairs, routine systems work). The 50 percent rule, more famous in real-estate investing, estimates ALL operating expenses (tax, insurance, maintenance, management) at roughly 50 percent of gross rent. They're different metrics and shouldn't be used interchangeably. For maintenance-specific budgeting, use the 1 percent or %-of-rent approach.

Capital expenditure reserves

Routine maintenance is one bucket. CapEx (roof, HVAC, water heater, appliances, major plumbing/electrical) is a second bucket that should be reserved separately. CapEx events are larger (often $3,000 to $15,000+) and less frequent (once every 5 to 25 years per system), but they will arrive. A common framework reserves an additional 5 to 10 percent of rent specifically for CapEx, on top of the routine maintenance reserve.

How to use this calculator

Enter property value, square footage, monthly rent, and property age. The calculator returns reserve estimates from all three rules of thumb and a blended monthly target. Use the higher end of the range for older properties or properties with deferred maintenance from prior ownership.

Frequently asked questions

How much should I budget for rental property maintenance?

Common rules of thumb: 1 percent of property value per year, $1 per square foot per year, or 5 to 10 percent of monthly rent. Older properties tend toward the higher end (1.5 to 2.5 percent of value). The three rules typically produce similar numbers for typical SFR rentals, which is part of why they're widely used.

What is the 1% rule for rental property maintenance?

The 1 percent rule estimates annual maintenance at 1 percent of the property's current value. For a $300,000 property, that's $3,000 per year, or $250 per month. The rule scales to older properties at 1.5 to 2.5 percent of value depending on condition and build year.

Should maintenance reserves and CapEx reserves be separate?

Yes. Maintenance covers routine work (small repairs, cleaning, fixture replacement). CapEx covers major systems (roof, HVAC, water heater, appliances, major plumbing/electrical). CapEx events are larger and less frequent, so reserving them separately prevents using maintenance reserves for big-ticket work and running out when small things break.

What is the 50% rule and how does it differ?

The 50 percent rule estimates total operating expenses (including maintenance, tax, insurance, management, vacancy) at roughly 50 percent of gross rent. It's a quick screening tool for evaluating deals. The 1 percent rule, by contrast, is just for maintenance. Use the 50 percent rule for deal screening; use the 1 percent rule (or %-of-rent) for setting maintenance budgets.

How does property age affect maintenance budget?

Older properties typically need 1.5 to 2 times the maintenance budget of newer ones. A property under 10 years old can budget at 1 percent of value. A property 10 to 30 years old typically needs 1.5 percent. Properties over 30 years old often need 2 to 4 percent of value annually, especially if there's deferred maintenance from prior ownership.
