ZESA Calculator

How much electricity do you get for the amount of money you have or how much will the units of electricity you want cost? This type of question is complex for a lot of people because of the way ZESA charges you for electricity. This is why we built this calculator to help domestic users of electricity easily answer this basic question.

To make electricity more affordable, ZESA has devised a stepped billing system which makes the first 300 units bought by a household in a calendar month cheaper. Households enjoy these 300 units whether they buy all the electricity at one go or even when they buy at different times.

For us to calculate what you need, we first need to know if you bought electricity earlier this month:

How much electricity did you previously buy for this month?

OK! Now that we know whether or not you bought electricity this month, we can calculate for your specific situation at this time with the calculator below. If you want to know how many ZESA units your money can buy just select to ‘calculate using ZW$’ then enter the money you have. If you know the number of units you want to buy but want to know how much you will pay, just select to ‘calculate using ZESA units’ then enter the number of units you want to buy:
