Utility bills are the classic unaudited spend — paid monthly for decades, compared against nothing. The benchmarks are knowable: US households average ~$140–170/mo electricity, $60–80 gas, $50–70 water/sewer, scaled predictably by home size, occupants and region. This estimator builds your expected stack, flags the out-of-line total, and maps each bill to its highest-yield lever.

The National Stack (and What Moves Each Line)

BillUS averageThe 80/20 levers
Electricity$145/mo (16¢/kWh avg — 11¢ WA to 40¢+ HI)HVAC is half the bill: each degree of thermostat ≈ 2–3%; then water heating, then the second fridge in the garage ($15–25/mo by itself)
Natural gas$65/mo (winter-weighted)Heating schedule + water heater at 120°F + duct/attic sealing
Water/sewer$55–70/moIrrigation (up to half of summer use); one running toilet wastes 200 gal/day silently — the food-dye-in-tank test takes 10 minutes
Internet$72/moPromo expiry — the loyalty tax; an annual retention call or plan rightsizing saves $15–30/mo (see the Speed Test tool for what you actually need)

Reading a High Bill Like an Auditor

  1. Get the 12-month graph (every utility portal has one) — the shape diagnoses: summer spikes = cooling/irrigation; winter = heating envelope; flat-and-high = always-on loads or a bad rate plan.
  2. Check the rate plan: time-of-use plans reward laundry/dishwasher/EV-charging after 9pm with 10–20% savings; many households sit on default plans that punish their actual pattern.
  3. Hunt phantom loads: a $25 kill-a-watt meter (or your utility's free lending program) finds the old freezer, the always-hot media stack, the well pump running long — always-on load above ~150W deserves a name.
  4. The envelope beats the gadgets: attic insulation and air sealing outperform every smart plug ever sold (see the Energy Upgrades tool for what rebates cover).

How to Use the Estimator

  1. Set home size, region and occupants; enter your real all-in monthly total.
  2. Read the gap — within ±15% is calibrated; above +20% is an audit invitation with the lever table as the checklist.
  3. Re-benchmark after changes; utilities are the rare bill where fixes show up on the very next statement.

Frequently Asked Questions

Why is my electric bill so high with nobody home all day?

Always-on loads: HVAC cycling to an aggressive setpoint, water heater losses, old refrigerators/freezers, pool pumps on 24/7 schedules, and the 10-15% 'phantom' baseline of idle electronics. The 12-month graph plus a plug meter names the culprit in an evening.

Do smart thermostats actually save money?

Yes, modestly and reliably: 8-12% of heating/cooling in studies — mostly by enforcing the schedule you'd forget. The bigger win is the schedule itself (setbacks when away/asleep), which a $25 programmable does too.

Is it cheaper to keep the house at one temperature all day?

No — that's the most persistent utility myth. Setbacks always save: heat loss scales with the indoor-outdoor gap, so 8 hours at a lower setpoint burns less, period. 'Recovery' costs less than what the setback saved.

Which appliances matter most?

HVAC (~45% of energy), water heater (~18%), then laundry/fridge/dishwasher. A pre-2010 fridge costs $10-20/mo more than a new one; a second garage fridge for beverages is the classic $200/yr luxury nobody prices.

How do I lower water bills fast?

Dye-test the toilets (leaks are silent and huge), shorten irrigation runtimes (or add a $30 rain sensor), and low-flow showerheads (also cuts water-HEATING). Sewer charges often key off winter water use — fixing leaks in January pays all year in some cities.

Are budget-billing plans a good idea?

They smooth cash flow (same payment monthly, trued up yearly) without changing totals — useful for budgeting, dangerous only if the flat payment hides a growing leak. Keep reading the actual-usage line.

Is my information private?

Yes — every figure computes locally in your browser.

Benchmark once, pull the 12-month graph, and fix the top lever per bill — utilities reward the single evening of attention with savings that repeat every month, forever, without willpower.
