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