What this calculator does
Estimate monthly utility cost and surface top savings opportunities.
How it's calculated
- Inputs are validated before running the calculator-specific compute() function.
- Core math is deterministic and implemented in src/lib/calculators/utility-bill-analyzer.ts.
- Results are recalculated instantly as values change and are shareable via query parameters.
- Disclosure assumptions and limitations are shown on-page for decision context.
Example
Example scenario: Electric: kWh used = 850 kWh; Electric: rate per kWh = 0.19 USD; Electric: fixed monthly fee = 18 USD; Gas: therms used = 40 therms. Sample output: Estimated monthly utility bill: $300.50
Common mistakes
- Using optimistic rates or appreciation assumptions without testing a conservative case.
- Ignoring taxes, insurance, HOA, or maintenance in monthly cost planning.
- Treating modeled outputs as guaranteed quotes rather than planning estimates.
- Not comparing at least two scenarios before making a financing decision.
- Skipping professional review for legal, tax, underwriting, or insurance details.
FAQs
What does seasonal multiplier do?
It scales all utility components together so you can model hotter, colder, or lower-use months quickly.
Can I leave gas or water at zero?
Yes. If a utility does not apply, set usage and fees to zero and the calculator will still work.
Are savings suggestions personalized with AI?
No. Suggestions are rule-based and prioritized from your largest cost components.
Should rates include taxes and riders?
Use your effective billed rate if possible, including recurring riders, to improve estimate accuracy.
Is this a bill replacement tool?
No. It is a budgeting estimate and does not replace your utility provider statement.
