How to Calculate Electric Meter Reading
Understanding Your Meter Type
Identifying your electric meter type is crucial for accurate reading. There are three primary types: digital, dial (analog), and smart meters. Digital meters display electricity usage directly on an LCD display, making them straightforward to read. Dial meters, featuring five dials numbered from 0 to 9, require careful interpretation, as you need to observe the position of the dials. Smart meters, equipped with digital displays and connectivity for monitoring via apps, provide real-time data and detailed consumption patterns.
Reading Your Meter
To perform electric meter readings, follow specific steps based on your meter type. For digital and smart meters, simply record the numbers displayed on the screen, usually the first five digits which represent the total kilowatt-hours (kWh) used. For dial meters, read each dial from right to left. Note down the number the dial has just passed, only if the dial to its immediate right is past zero. If not, you take the lower number.
Calculating Usage
After obtaining your current reading, calculate your energy consumption by subtracting the previous month's reading from the current reading. Express this calculation with the formula: Current Reading - Last Month's Reading = kWh Used. This value indicates the total kWh consumed during the billing period.
How to Calculate Electric Meter Reading
Understanding Your Electric Meter
Electric meters, including digital, dial (analogue), and smart types, measure electricity consumption in kilowatt-hours (kWh). Digital and smart meters display the consumption directly on an LCD screen, making them easier to read by just noting the first five numbers displayed. In contrast, dial meters require reading the position of up to five dials, noting the numbers only if the dial to the right has passed zero.
Steps to Calculate Your Meter Reading
To determine the amount of electricity used, start by reading your electric meter. For digital meters, record the displayed number. For dial meters, read each dial from right to left, recording the numbers pointed by the dials unless a subsequent dial hasn't passed zero. Subtract the previous month's reading from the current reading to find the total kWh used during the period.
Calculating Your Electric Bill
After obtaining the total kWh usage, multiply this number by your utility's kWh rate to calculate the total energy charge. Add any fixed monthly fees to this amount to find your final electric bill. For example, if the rate is $0.10 per kWh and you used 55 kWh, your energy charge would be 55 x $0.10 = $5.50.
Example Calculation
Consider a previous meter reading of 12345 kWh and a current reading of 12400 kWh. The electricity used is 12400 - 12345 = 55 kWh. At a rate of $0.10 per kWh, the energy charge is 55 x $0.10 = $5.50.

Examples of Calculating Electric Meter Readings
Example 1: Basic Calculation for Digital Meters
Determine your electricity usage by subtracting last month's meter reading from the current reading. If your previous reading was 1275 and the current is 1325, your usage is 1325 - 1275 = 50 kilowatt-hours (kWh).
Example 2: Factor in Multi-Rate Meters
For meters with multiple rates (peak and off-peak), calculate each separately. Assume peak reading moves from 575 to 600, and off-peak from 1200 to 1250. Calculate: Peak usage = 600 - 575 = 25 kWh; Off-peak usage = 1250 - 1200 = 50 kWh. Add both for total usage.
Example 3: Analogue Meter Reading Correction
With analogue meters, align the number carefully, taking lower if between two numbers. If indicators point to 9 just before 0, and the next to 6, your reading should be 596. Calculate usage by subtracting from the previous month.

Frequently Asked Questions
How do I read an analog electric meter?
To read an analog electric meter, identify and observe the five dials. Record the numbers that each pointer is closest to, choosing the lower number if the pointer is between two numbers. Subtract the previous meter reading from the current reading to calculate usage.
How do I read a digital electric meter?
Reading a digital electric meter involves locating the display on the meter and recording the first five numbers displayed. Ignore any numbers starting with 0.1. The numbers indicate the total kWh used since the last meter reading.
How do I read a smart electric meter?
To read a smart electric meter, check the display on the meter. Smart meters often connect to apps that can provide detailed breakdowns and insights into your electricity usage. Brands like Itron, Landis+Gyr, or Sensus are common.
How do I calculate my electric meter reading for billing?
To calculate your electric meter reading for billing, subtract the previous meter reading from the current meter reading. This will give you the total kilowatt-hours (kWh) used, which is used to calculate your bill by multiplying by the rate per kWh.
What is the difference between an energy monitor and a smart meter?
Energy monitors and smart meters both track electricity usage but in different ways. Energy monitors provide real-time data and detailed insights, allowing homeowners to identify specific areas to reduce usage. Smart meters provide more general usage data and are often connected to utility systems.
Conclusion
Calculating electric meter readings accurately is crucial for managing energy consumption and cost efficiency. By understanding how to read and calculate these figures, you can track your electricity usage effectively.
