Explain What Each Line on a Utility Bill Actually Means

A utility bill mixes standing charges, usage rates, and the odd adjustment line with no explanation attached. This breaks down each item in plain terms, distinguishes the fixed charges from the usage based ones, and flags anything that looks like an estimate rather than an actual meter reading, so you know exactly what you are paying for.
