This calculator estimates utility savings from expected bill reduction percentages and applies optional utility rate escalation to project five-year outcomes. It helps homeowners, renters, and facility managers compare savings scenarios before committing to specific upgrade packages.

Decision Guidance

Start with lower-cost actions to lock in quick wins, then evaluate larger capital upgrades once baseline demand is reduced. This sequence often improves payback and can reduce the required size of downstream solar or HVAC investments.

• Use a 12-month bill average to avoid seasonal bias
• Model multiple reduction targets for sensitivity analysis
• Include expected rebate effects in upfront cost assumptions
• Account for projected utility rate increases over time
• Prioritize measures with shortest payback when budget constrained
• Revisit assumptions after implementing first-phase improvements
