An independent, free calculator that works out how many units of prepaid electricity your money actually buys in your part of South Africa.
Most prepaid electricity calculators divide the amount you spend by a single rate. In South Africa that produces the wrong answer for most people, for two reasons. Municipal tariffs are usually tiered, so the price per unit climbs as you buy more within a calendar month. And several metros deduct a fixed monthly service charge from your first purchase of the month before any units are loaded at all.
The practical effect catches people out constantly. In Johannesburg, a R200 first purchase of the month buys no units whatsoever, because the fixed charge alone is R241.50. Someone budgeting around a simple rate calculation would have no idea why their electricity did not arrive.
This site models both mechanics properly and shows the breakdown, so you can see exactly where your money went rather than just getting a number.
Rates are taken from each municipality's own published tariff schedule and Eskom's Schedule of Standard Prices — the primary documents, not third-party summaries. Every result displays the date the figures were last checked and links directly to the source document so you can verify them yourself.
Figures are stored VAT-inclusive, which is what actually leaves your prepaid balance. Some municipalities publish their schedules excluding VAT, which is a common source of confusion when people compare tariffs between areas.
South Africa has roughly 180 licensed municipal electricity distributors, each with its own NERSA-approved schedule. Covering all of them is an ongoing project. Where an area is not yet covered, the calculator says so plainly instead of substituting another supplier's rates — a confident wrong number is worse than an honest gap when someone is budgeting.
This site is not affiliated with Eskom, NERSA, or any municipality. It does not sell electricity, process payments, or handle prepaid tokens. It is an estimation tool only. For an exact figure, always refer to your own receipt or your municipality directly.
The site is free to use. Running costs are covered by advertising and, where relevant, affiliate links to energy-related products. This never affects the tariff figures shown — the rates come from official schedules and nothing else.
