Formula
Cost = kWh × Rate per kWh
For periodic conversions:
Daily cost = (Monthly kWh ÷ 30) × Rate
Monthly cost = kWh/day × 30 × Rate
Annual cost = kWh/day × 365 × Rate
Monthly cost = kWh/day × 30 × Rate
Annual cost = kWh/day × 365 × Rate

Frequently Asked Questions
How do I convert kWh to cost?
Multiply kWh by your electricity rate. Cost = kWh × rate. If your bill shows 350 kWh at $0.15/kWh, the energy charge is $52.50. Your total bill will also include fixed charges like daily supply charges and distribution fees.
How much does 1 kWh cost?
It varies by country and utility. US average 2024: about $0.15/kWh. UK 2024: about £0.25–£0.30/kWh. Germany: around €0.32/kWh (one of Europe's highest). Australia: $0.28–$0.35 AUD/kWh. Always use your actual bill rate for accurate calculations.
How do I find my electricity rate?
Your electricity bill shows the rate per kWh — look for "unit rate," "energy tariff," or "price per kWh." It may differ from a quoted tariff if you're on block pricing (where the rate changes above a usage threshold). Time-of-use tariffs have different peak and off-peak rates — use the rate that applies to when the equipment runs.
