Whole-Home AC Bill Planner
Real homes rarely have identical AC units. Add each unit or group with its own input power, daily runtime and load factor, then see the combined monthly electricity impact under Saudi residential tariff tiers.
Use electrical input power in kW. Cooling tons and BTU/h describe cooling capacity, not electrical consumption. For truly identical units, increase quantity instead of adding duplicate rows.
Automatic follows the current Saudi date, not the date your bill was issued. For past bills choose the actual period of consumption; periods crossing 1 January 2027 need separate estimates for each part. official tariff.
From January 2027, the breaker-based fixed fee is 70โ100 SAR, prorated by bill days/30. The 2026 meter reading fee is 10โ30 SAR. Fees shown before VAT. official tariff.
Use a representative monthly figure from your bill when possible.
Monthly baseline use scales to the selected billing days. Above 30 days the tier limit expands proportionally. For shorter periods we assume the full 6,000 kWh tier (provider-caused); other reasons may change the threshold.
Why use a whole-home scenario?
The single-AC cost calculator is ideal for one unit or a group of identical units. This planner lets a bedroom AC, living-room AC and other units use different input powers, schedules and load factors while still sharing one household tariff baseline.
How the 6,000 kWh threshold is handled
The 2026 residential rates are 18/30 halala per kWh, rising to 21/33 halala from 1 January 2027, with the same 6,000 kWh monthly threshold. The planner calculates the energy bill before and after the AC scenario and shows how much added AC consumption lands in each tier.
What this does not model
This estimate adds the applicable 2026 meter-reading fee or 2027 breaker-based fixed fee, but is not a replica of a complete Saudi Electricity bill and excludes special adjustments. Load factor is an operating assumption; measured energy data or reliable annual label consumption can be more precise for model-to-model comparison.
See the official sources and methodology. If you are still deciding cooling sizes rather than actual AC models, start with the multi-room AC planner.
FAQ
Should every AC be a separate row?
Use a separate row when input power, runtime or load factor differs. For genuinely identical units, use quantity.
What happens if baseline use is close to 6,000 kWh?
The tool splits added kWh between the rates for the selected year: 18/30 halala in 2026 or 21/33 in 2027.
Do you upload my room or unit names?
No. The scenario is stored in Local Storage in your browser so you can continue later, and the CSV export is generated locally.
