The Electricity Consumption Calculator estimates a general arithmetic estimate for your scenario from the quantities, rates, period, units and other assumptions requested on the page. Replace the example values with your own electricity consumption figures and recalculate after changing an assumption. Use it to compare scenarios, then verify any current rate or fee before acting.
Estimates of electricity consumption for the next month.
This calculation result is suitable for preliminary planning. Actual figures should be checked from documents or official sources before making important decisions.
The calculation is based on the information you enter on this page.
Special cases may require additional information.

Yes, this is an estimate. The actual value may vary depending on the current conditions and prices.
Who should I consult for more information?
You should consult an architect, contractor or construction expert for advice.
What is the electricity rate in Thailand?
Progressive Rate — The more you use, the more expensive it is per unit. MEA/PEA has a rate of 3 per period as announced by the Energy Regulatory Commission (EGC) plus the FT (Fuel Tariff) that changes every 4 month.
What is the FT value and how does it affect the power value?
FT (Fuel Adjustment Charge) is an adjustment based on fuel costs, adjusted every 4 months. If FT is positive, it means the electricity bill is more expensive. If it's negative it's cheaper. As a result, the monthly electricity bill can change by 5-15%.
How can we save on electricity?
Turn off non-user devices (standby consumes 5-10% of electricity bills), replace old bulbs with LEDs, set air conditioning to 25-26°C, wash once full, check insulation and seal refrigerator doors.
What is the difference between the electric meter size 5(15) A and 15(45) A?
The size of the meter determines the maximum current. General households use 5(15) A sufficient. Large houses or those with high-power appliances should use 15(45) A. Electricity charges are the same, but the monthly service charges are different.

How to use the Electricity Consumption Calculator
Use this page to test a specific electricity consumption scenario. Enter your own values in the calculator above, review the units beside each field, and recalculate after changing an assumption. The result updates the electricity consumption estimate instead of relying on a generic example.
Build a baseline electricity consumption case with figures that match your situation.
Run a second electricity consumption case after changing the rate, period, quantity or other key assumption.
Record the difference between the two electricity consumption results and the input responsible for it.
Inputs for the electricity consumption estimate
For this electricity consumption calculation, check the quantities, rates, period, units and other assumptions requested on the page. The result is designed to show a general arithmetic estimate for your scenario, not a guaranteed provider price or official decision.
How the electricity consumption result is calculated
The calculator applies the displayed inputs to the stated arithmetic relationship. Reusing the same electricity consumption inputs will produce the same estimate, which makes the page suitable for controlled scenario comparisons.
Checks for a electricity consumption decision
Confirm any current rate, threshold or provider rule that could change the final amount. For electricity consumption, Use the result as a planning estimate and confirm any rate, rule or threshold that may have changed before acting. Recheck the entered values and units if the result looks unexpected.
