Where do the benchmark averages come from?

Electric + gas: EIA Residential Energy Consumption Survey + monthly retail price data (2025). Water: EPA WaterSense average household. Internet: FCC Communications Marketplace Report. Mobile: BLS Consumer Expenditure Survey. Streaming: Deloitte Digital Media Trends survey. Trash: BLS CES housing-services category. All US-residential figures.

What counts as an 'anomaly'?

Any line where your bill is more than 25% above the US average for that utility. The threshold is conservative — if you live in a high-cost state (CA, MA, NY, HI for electric; AK for everything) you'll legitimately be over the national average. The flag is a prompt to check, not a verdict.

Does it know my state's average?

Today the calculator uses national averages. State-level rates vary widely (e.g. Hawaii electric is ~3× the national average; Idaho is half). The next iteration will let you pick a state for state-specific benchmarks. For now, treat the comparison as a sanity check, not the final word.

Why no fixed recurring charge field?

Fixed charges are baked into the total bill amount you enter, so the comparison still works. If you want to break out demand charges + delivery fees + supply, the per-line tips for electric + gas explain how to read your bill stub. Most households don't have separate visibility into those without their utility's app.

Reduction tips per line

Power company

Switch to LED bulbs everywhere (save ~$45/yr vs incandescent)
Heat pump replaces resistance heat → 50–70% bill cut in winter
Smart thermostat (8% average HVAC savings)

Natural gas

Air-seal + insulate (typically 15% bill cut in cold climates)
Heat pump water heater replaces gas water heater (40–50% bill cut)
Lower thermostat 3°F overnight (saves ~10%)

City water + sewer

Check for hidden leaks: water meter shouldn't move when no one's using water
Low-flow showerheads (≤2.0 gpm) save 25–60% on shower water
Toilet flapper replacement ($5) fixes the #1 leak source

Home internet

Negotiate or threaten to cancel — $20–40/mo retention discount is typical
Drop the rented modem ($14/mo) for a $90 one-time purchase (payback 6 mo)
Switch to fiber if available — usually faster + cheaper than cable

Cell phones

Switch to MVNO (Mint, Visible, US Mobile) — same coverage, $15–25/line
Multi-line family plans on one carrier beat individual lines
Drop unlimited if you use <30 GB; pay-per-GB plans are cheaper

Streaming + subs

Audit annually — average household pays for 4+ streamers but actively uses 2
Bundle deals (Disney+/Hulu/ESPN+, Apple One, Spotify+Hulu) often beat à la carte
Family plans split 4 ways with friends save 60–75% per person on supported services

Trash + recycling

Smaller bin size (35 vs 96 gal) often cuts cost 30%
Drop weekly to bi-weekly pickup if your bin is half-full
Some municipalities run drop-off centers free on weekends — useful for big purges

What it does

Track every household utility bill — electricity, natural gas, water + sewer, internet, mobile, streaming, trash — in one dashboard. Most competitors give you a calculator per-utility and you stitch them together yourself. We do the stitching, then benchmark each line against 2025 US averages and flag anomalies before you ever look up your state’s rate.

Numbers come from EIA (electric + gas), EPA (water), FCC (broadband), and BLS (mobile, trash). Every benchmark is cited so you can verify the source. Saved to your browser localStorage so you can track month-over-month — no account, no upload.

Show the math + sources

Formula

Per line: monthly = amount × (30 / periodDays). Annualized = monthly × 12. Anomaly flag fires when monthly > avgMonthly × 1.25 for that utility category. Effective rate (where unit billing applies) = amount ÷ units, compared against avgRate per category.

What this assumes

US-residential averages from federal sources. Single-family / typical apartment household. Does not adjust for state-level cost variance (HI/CA/MA run higher; ID/WA/UT lower) or for income-based programs (Lifeline, ACP, LIHEAP). Tax + delivery fees are baked into the bill amount you enter.
