Repair and Maintenance Ratio Calculator
Repair and maintenance spend is the first line most underwriters stress test. Too low and the property has deferred maintenance the new owner will inherit; too high and there's an operating problem or asset is past its useful life. This calculator ratios R&M to EGI and checks per-unit and per-SF against industry benchmarks.

How the math works
Repair and maintenance spend should land between roughly $550 and $850 per unit per year on stabilized multifamily. R&M ratio to EGI is another read on whether spend is in line — 6-9% is typical. Very low R&M usually means deferred maintenance that will hit capex later.
R&M does not include planned capex replacements (roof, HVAC, parking lot). That's a separate replacement reserve line.
How to Use
- Enter annual R&M spend from the T12 P&L.
- Enter effective gross income for the same period.
- Enter unit count and rentable square footage.
- Compare the ratios against typical multifamily benchmarks.
Frequently Asked Questions
What counts as R&M?
Paint, patch work, small plumbing and electrical, HVAC service calls, pest control, appliance repair, landscaping breakage, make-ready touch-up. Roof replacement, HVAC replacement, and paving are capex — not R&M.
Why does R&M grow with age?
Older buildings have more component failures. A 1970s multifamily can run $900-1,100 per unit per year on R&M alone. Newer construction settles around $450-600.
Low R&M — good or bad?
Often bad. It suggests the owner is deferring work. When you take over, expect a capex surge for items that should have been caught during regular maintenance.
