COMMON QUESTIONS
Good to know.
Electricity tariffs and charges differ across South Africa.
Why did I receive fewer electricity units for the same amount?⌄
Block tariffs, increases, fixed charges, debt recovery or municipal fees may affect units.
Is buying at the start of the month cheaper?⌄
It depends on your tariff. Splitting purchases normally does not reset monthly usage.
Does the tool know my municipal tariff?⌄
No. The analyser uses the amount and units on your real token.
Are the results exact?⌄
No. Results are estimates based on your inputs.
OUR METHOD
Simple maths.
Transparent assumptions.
Effective token rate = rand paid ÷ units received.
Appliance consumption = watts × hours × quantity ÷ 1,000.
Days remaining = current units ÷ average daily usage.
