Utilities Calculators
Estimate everyday running costs — electricity and other utilities — at South African tariffs.
Quick utility calculators that work in Rand and use realistic South African per-unit pricing so you can budget your monthly bill or compare appliance running costs.
Make household running costs visible
Electricity, generator fuel and solar payback decisions are easier when the monthly rand impact is clear. These utility calculators help households and small businesses turn kWh, litres, tariffs and system costs into plain estimates that can be compared against a municipal account, prepaid meter usage or installer quote before committing to a new appliance, backup system or tariff change. Use them when you want a quick sense of monthly affordability rather than a sales-led estimate.
Check your own tariff
South African electricity pricing varies by municipality, Eskom tariff, usage block and time of year. Treat the default values as examples and enter the rate from your own bill whenever possible. For solar and generator estimates, include maintenance, fuel changes, battery replacement, inverter efficiency and realistic load-shedding patterns before relying on a payback figure for a household or small business budget. Revisit the inputs whenever tariffs or fuel prices change.
