What the numbers on your meter actually show
Your electric meter measures how much electricity you use, displayed as kilowatt-hours (kWh). The main number you need to know is the one that keeps climbing — that is your total electricity consumption since the meter was installed. Your utility company reads this number once a month (or you read it yourself if you have a smart meter) and charges you based on how much it increased from the previous month.
Most meters have a row of five to eight dials or a digital display. If your meter has dials, they work like an odometer in a car — each dial represents a different digit, and you read them from left to right. If it is digital, you straightforward read the numbers as they appear, ignoring any decimal points or letters after the main number.
The meter also shows you real-time information: how much power you are using right now, measured in watts or kilowatts. This changes constantly as you turn appliances on and off. Understanding both the total (kWh) and the current use (watts) helps you see which devices cost the most to run.
Key Takeaways
- The main number on your meter is kilowatt-hours (kWh), which shows your total electricity use — your bill is based on how much this number increases each month.
- On a dial meter, read left to right and note that each dial spins in the opposite direction from the one next to it, so you must watch carefully where the pointer actually lands.
- On a digital meter, straightforward read the numbers displayed, ignoring decimal points or letters that appear after the main reading.
- The real-time power display (in watts) shows what you are using at that exact moment and changes as you turn appliances on and off.
- Your monthly bill comes from subtracting last month's meter reading from this month's reading, then multiplying by your utility's rate per kWh.
How to read a dial meter step by step
Dial meters have four or five numbered dials arranged in a row. The leftmost dial represents the highest value (thousands), and each dial to the right represents a smaller unit (hundreds, tens, ones, and sometimes tenths). The pointer on each dial moves clockwise or counterclockwise depending on which dial it is — they alternate direction.
To read the meter correctly, look at each dial from left to right. Write down the number the pointer has just passed, not the number it is pointing at. If the pointer is between two numbers, always use the lower number. For example, if a pointer is between 3 and 4, write down 3. This matters because the dials do not all move at the same speed, and the pointer may be in between numbers when you look.
If you see a dial pointer pointing directly at a number with no room for doubt, that is fine — write that number down. But if it looks like it could be on either side, go with the lower number. Once you have written down all five digits in order from left to right, you have your meter reading.
How to read a digital meter
Digital meters are much simpler. The display shows a number that looks like an odometer reading — typically five to eight digits. Read the numbers exactly as they appear, from left to right. Ignore any decimal point or letters (like "kWh") that appear after the main number.
Some digital meters have a small LCD screen that cycles through different information: your total consumption, your current power use in watts, and sometimes your rate or time of use. The main reading you need for your bill is the one labeled as total consumption or cumulative use — this is the number that only goes up, never down.
If your meter has a button or you can see multiple screens, look for the display that shows a five or six-digit number without any decimal point in the middle. That is your consumption reading. Write it down exactly as shown, and compare it to last month's reading to see how much electricity you used.
Understanding kilowatt-hours and what they cost
A kilowatt-hour is the amount of electricity a 1,000-watt device uses in one hour. If you run a 1,000-watt space heater for one hour, you use 1 kWh. If you run a 100-watt light bulb for 10 hours, you also use 1 kWh. Your utility company charges you a set price per kWh — this rate varies by location and utility, but it is the number you multiply by your monthly consumption to get your bill.
For example, if you used 750 kWh last month and your rate is $0.12 per kWh, your electricity charge would be 750 × $0.12 = $90. Your actual bill may be higher because utilities also add fees for meter reading, delivery, taxes, and sometimes demand charges, but the kWh consumption is the main part you control.
The real-time power display on your meter (shown in watts or kilowatts) tells you what is happening right now. A microwave running might show 1,200 watts. A refrigerator might show 150 watts. By watching this number change as you turn things on and off, you can see which appliances use the most power at any given moment.
What the other numbers and displays mean
Many meters have additional information beyond the main consumption reading. Some show a demand indicator — the highest amount of power you used at any single moment during the billing period. Utilities sometimes charge extra for high demand, especially for businesses. This number resets each month.
Smart meters often display time-of-use information, showing you when you used electricity (morning, afternoon, evening, night). Some utilities charge different rates depending on the time of day, so knowing when you use power can help you shift usage to cheaper hours if you want to lower your bill.
You may also see a test button, a dial labeled "pulse" or "test," or a small red light that blinks. These are for utility company technicians and meter testing — you do not need to interact with them. If you see a tamper seal or lock on the meter, do not remove it; that is there to prevent unauthorized changes.
How to track your usage month to month
Write down your meter reading on the same day each month — many people do it on their billing date or the first of the month. Subtract the previous month's reading from the current month's reading. The difference is how many kWh you used that month. For example, if last month you read 45,230 kWh and this month you read 45,980 kWh, you used 750 kWh.
Keep a straightforward log in a notebook or spreadsheet. Over several months, you will see patterns: winter months may be higher if you use electric heat, summer months higher if you use air conditioning. If you see a sudden spike, check whether you left something running, had guests, or started using a new appliance.
If your utility offers an online account portal, you can also see your usage history there without reading the meter yourself. Many utilities now provide this data automatically from smart meters, updated daily or weekly. This makes it easier to spot unusual usage without having to write numbers down.
What to do if you cannot read your meter or it seems wrong
If your meter is blocked by vegetation, snow, or debris, clear it away carefully. Do not use force or tools that might damage the meter. If it is in a locked box or behind a gate, contact your utility company to schedule a reading — they have access and can read it for you.
If your reading seems unusually high, first check whether you have a new appliance, guests staying longer than usual, or a change in season. Then compare your reading to your bill — your utility should show the reading they used to calculate your charge. If the numbers do not match, call your utility's customer service line and ask them to verify the reading. They can also check for leaks or equipment problems if your usage has genuinely spiked without explanation.
If you believe your meter is broken or running fast, your utility can test it. There is usually a small fee for this service, but if the meter is found to be faulty, they will credit your account. Do not assume the meter is wrong just because your bill is higher than you expected — most meters are accurate, and higher bills usually come from higher usage.
Frequently Asked Questions
What is the difference between a kilowatt and a kilowatt-hour?
A kilowatt (kW) is a measure of power — how much electricity something uses at one moment. A kilowatt-hour (kWh) is a measure of energy — how much electricity you use over time. A 1,000-watt device running for one hour uses 1 kWh. Your meter measures kWh because that is what you pay for.
Why does my meter reading have a decimal point?
Some meters show tenths of a kWh for more precision. For billing purposes, your utility rounds to the nearest whole number. If your meter shows 45,230.7 kWh, your bill is based on 45,231 kWh. The decimal point does not affect your bill significantly unless you are tracking very small changes.
Can I read my meter wrong and get charged incorrectly?
If you read your own meter and report it to your utility, yes — a misread could affect your bill. But most utilities read meters themselves or use smart meters that report automatically, so your reading does not go on your bill unless you specifically submit it. If you are unsure, ask your utility whether they want you to report readings or if they handle it.
What does it mean if my meter is not moving?
If the main consumption number has not changed in several days, you are straightforward using very little electricity. Meters only move when you are drawing power. If you have been away or using almost nothing, the number stays the same. If you have been home and using appliances normally but the meter has not moved in weeks, contact your utility — there may be a problem.
Do smart meters show different information than dial meters?
Smart meters show the same main consumption number as dial meters, but they display it digitally and can send readings to your utility automatically. Many smart meters also show real-time power use, time-of-use breakdowns, and other details on a screen or through a mobile app. The billing information is the same — only the display method changes.
