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 this calculator works

What this page estimates

This Repair and Maintenance Ratio Calculator is built to give a quick, browser-based estimate for repair and maintenance ratio. 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. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.
Check the related calculators below when the next decision depends on a different assumption.

How to interpret the repair and maintenance ratio result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this repair and maintenance ratio estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

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.
