Energy Cost Calculator
Estimate your costs and potential savings.
How the calculator works
Annual electricity cost = monthly usage (kWh) × electricity price (per kWh) × 12. Estimated annual savings = annual cost × assumed percentage reduction. All inputs can be edited. Country selection changes the displayed currency and loads a starting example, not a verified current tariff.
The calculator does not include fixed utility charges, complex time-of-use tariffs, taxes, solar generation, battery losses, installation costs or financing. A 20% reduction is a hypothetical scenario, not a prediction of what solar or any product will achieve.
