Home Maintenance Budget Calculator
Calculate home maintenance budget using the 1-2% rule and square footage method.
Returns monthly savings target and category breakdown including HVAC and roof.
Annual home maintenance budgeting follows the industry-standard 1% Rule as a baseline, with several refinements based on home age, condition, and regional climate.
The 1% Rule:
Annual Budget = Home Value × 1%
The Square Footage Rule:
Annual Budget = Square Footage × $1.00
For older homes (20+ years), a more conservative estimate:
Annual Budget = Home Value × 1.5–2%
A more detailed bottom-up approach by system:
Total = HVAC + Roof + Plumbing + Electrical + Exterior + Appliances + Landscaping + Misc
Worked Example — $350,000 home, 2,200 sq ft, 15 years old:
- 1% rule: $3,500/year
- Square footage rule: $2,200/year
- Age-adjusted (1.5%): $5,250/year
Recommended budget: $4,000–$5,000/year (1.1–1.5%)
System-by-System Breakdown (annual reserve):
- HVAC (replace ~$6,000, lifespan 15yr): $400/yr
- Roof (replace ~$15,000, lifespan 25yr): $600/yr
- Water heater (replace ~$1,200, lifespan 10yr): $120/yr
- Exterior paint (~$4,000 every 7yr): $571/yr
- Gutters/drainage: $150/yr
- Plumbing/electrical miscellaneous: $300/yr
- Appliances reserve: $400/yr
- Landscaping/pest/misc: $500/yr
- System total ≈ $3,041/year
Key Insight: Homeowners who fund a dedicated maintenance account and spend proactively spend 30–40% less over 10 years than those who defer and pay emergency rates. A $500 HVAC tune-up can prevent a $7,000 compressor replacement.
