Core utility paths

Start with one of the six main bill workflows.

The homepage now groups the site by intent: diagnose a bill, explain charges, estimate utilities, price a device, or plan payments.

Open path

Payment planning

Smooth or split a balance

Check budget billing, payment plans, late fees, and fixed-fee pressure.

Open path

Start with the problem

Open the path that matches what you are trying to solve.

Use this when you do not know which calculator to start with. Each path points to the strongest diagnosis, estimate, or savings workflow.

Start with my exact problem

Choose high electric bill, high water bill, appliance cost, confusing line item, or savings target.

Choose path

My utility bill is high

Diagnose the whole bill before deciding whether electric, water, sewer, or fixed fees changed.

Choose path

Audit my whole bill

Check billing days, daily kWh, daily water use, all-in rates, fixed fees, and meter reads.

Choose path

Compare billing days

Normalize two bills by days before blaming usage, rates, fixed fees, or a leak.

Choose path

Split a partial bill

Prorate utilities by move-in days, move-out days, roommate count, and one-time fees.

Estimate my total utilities

Combine electricity, water, sewer, fixed fees, and other monthly utilities before drilling down.

Choose path

Estimate utilities by state

Start from state-specific electric assumptions, then add water, sewer, fixed fees, and other utilities.

Choose path

My water bill jumped

Compare two water bills to separate gallons, leaks, sewer, and fixed-fee pressure.

Choose path

What usage is normal?
