How to Use This Calculator
  1. Enter Home Value and Home Age — older homes typically require higher maintenance budgets due to aging systems.
  2. Input Home Sq Ft to scale maintenance costs proportionally to the size of the property.
  3. Select Climate (mild, moderate, or harsh) since extreme weather accelerates wear on roofing, siding, and HVAC.
  4. Review Annual Budget and Monthly Budget — the 1–2% of home value rule is a common starting point.
  5. Check HVAC Reserve, Roof Reserve, and Plumbing Reserve to see how the annual budget breaks down by system.
  6. Use Percent of Value to compare your budget to the industry benchmark and adjust for your home's specific condition.

How the result changes with Home Value

Home ValueAnnual Maintenance Budget
545,000$6,540.00
1,782,500$21,390.00

What each input means

Home Value
Current market value of your home. The 1% rule uses this as the starting point for annual maintenance budgeting.
Home Age
Age of the home in years. Older homes typically require a larger maintenance budget.
Home Size
Total finished square footage. Larger homes have more systems, surfaces, and components to maintain.
Climate
0 = Mild (temperate, minimal freeze/thaw), 1 = Moderate (seasonal variation), 2 = Harsh (extreme heat, cold, or humidity).

What each result means

Annual Maintenance Budget
Recommended total annual maintenance budget for your home.
Monthly Set-Aside
Amount to save each month toward maintenance expenses.
Percent of Home Value
Your maintenance budget as a percentage of home value (1% is the baseline rule).
HVAC Reserve
Recommended annual reserve for heating and cooling system maintenance and replacement.
Roof Reserve
Recommended annual reserve for roof maintenance and eventual replacement.
Plumbing Reserve
Recommended annual reserve for plumbing repairs and water heater replacement.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Home Value = 350000, Home Age = 15, Home Size = 2000, Climate = 1 = 4 input(s) provided
  2. Calculate Annual Maintenance Budget
    Annual Maintenance Budget
    4200 = $4,200
  3. Calculate Monthly Set-Aside
    Monthly Set-Aside
    350 = $350
  4. Calculate Percent of Home Value
    Percent of Home Value
    1.2 = 1.2
