30-Year Cost Projection
What does skipping home maintenance really cost?
Regular upkeep compounds quietly in your favor. Neglect compounds against you. This calculator shows the cumulative cost of each path over 30 years — select the tasks that apply to your home and see the gap widen in real time.
Cumulative Cost Over 30 Years
Maintained path: recurring service costs paid on schedule. Neglected path: full replacement costs incurred when items fail ahead of their serviced lifespan. Unchecked items use the maintained cost on both paths.

Common Questions
Home maintenance costs, explained
How much does home maintenance cost per year?
A commonly cited rule of thumb is 1–2% of your home's purchase price per year. For a $350,000 home, that's $3,500–$7,000 annually. Our calculator shows that proactive maintenance across 25 major tasks typically runs $3,000–$5,000 per year depending on which systems apply to your home — far less than the cost of emergency replacements when systems fail prematurely.
What happens if you neglect home maintenance?
Neglected maintenance shortens the lifespan of every major home system. A well-maintained HVAC lasts 20 years; a neglected one typically fails in 12. Clogged gutters cause foundation damage costing $10,000–$20,000. Skipped dryer vent cleaning is a leading cause of house fires. Over 30 years, cumulative neglect across all major systems commonly exceeds $100,000 in avoidable replacement costs.
How much money does preventive maintenance actually save?
Contractor data consistently shows that every $1 spent on preventive maintenance saves $5–$10 in emergency repairs and early replacement costs. Over a 30-year period, homeowners who follow a regular schedule for HVAC, roofing, gutters, plumbing, and major appliances typically save $50,000–$150,000 compared to those who only react to failures.
Which maintenance tasks have the highest ROI?
The highest-return tasks are those that prevent catastrophic failures:
- HVAC filter changes — $20/quarter prevents an $8,000 system replacement
- Gutter cleaning — $150/cleaning prevents $15,000 in foundation repair
- Dryer vent cleaning — $120/year prevents fire damage
- Sump pump testing — free DIY prevents $20,000 in flood cleanup
Tasks that protect structural systems and prevent water intrusion consistently deliver the best return.
How often should you do home maintenance?
Frequency varies by system:
- Quarterly: HVAC filter change
- Twice a year: Gutter cleaning (spring & fall)
- Annually: Water heater flush, chimney inspection, dryer vent cleaning, pest control
- Every 2–3 years: Deck sealing, driveway sealcoating, caulking
- Every 5+ years: Roof inspection, HVAC duct cleaning, electrical panel inspection
A home maintenance app or calendar reminders is the most reliable way to stay on schedule.
Is home maintenance tax deductible?
For a primary residence, routine home maintenance is generally not tax deductible. However, home improvements that add value or adapt the home for medical use may qualify for tax benefits. If you use part of your home as a dedicated business office, a proportional share of maintenance costs may be deductible. Consult a tax professional for guidance specific to your situation.
