#### Formulas Used

Per-System Annual Cost: Cost = BaseRate × LaborMultiplier × ClimateMultiplier × AgeMultiplier

HVAC: ($300 tune-up + $60 filters) × HVAC Age Factor × Labor × Climate
Plumbing: ($150 + $8 × bathrooms × 12) × Labor × Age
Electrical: ($200 + $0.02 × sqft) × Labor × Age
Roofing: (sqft × 1.15 pitch factor × $/sqft/yr by type) × Labor × Climate × Age
Exterior: ($300 gutters + $0.15 × sqft) × Labor × Climate
Pool (if applicable): $1,800 base × Labor × Climate
1% Rule Benchmark: Home Value × 0.01
$1/sqft Rule: Square Footage × $1.00
Emergency Reserve: Total Annual Cost × 10%
Monthly Savings Target: (Annual Cost + Reserve) ÷ 12
