Calculate exactly what your ceramic heater costs to run per hour, day, and month. Free US tool with 2026 rates.
Ceramic heaters use a heated ceramic element with a fan to distribute warm air. They warm rooms in 2–3 minutes but stop producing heat immediately when turned off. To calculate cost: divide wattage by 1,000 to get kWh per hour, then multiply by your electricity rate. For a 1,500W ceramic heater at $0.15/kWh: 1.5 kWh × $0.15 = $0.23 per hour.
Unlike oil heaters, ceramic heaters don't retain heat — they only warm the room while running. This makes them ideal for short sessions (1–4 hours) where you need quick warmth. For all-night use, the continuous running cost can add up. A 1,500W ceramic heater running 8 hrs/day costs ~$55/month at $0.15/kWh.

| Wattage | Cost/Hour | Cost/Day | Cost/Month |
|---|---|---|---|
| 750W | $0.11 | $0.45 | $13.50 |
| 1,000W | $0.15 | $0.60 | $18.00 |
| 1,500W | $0.23 | $0.90 | $27.00 |
| 1,500W (8 hrs) | $0.23 | $1.84 | $55.20 |
US average $0.15/kWh. 30 days/month. Day costs assume 4 hrs/day except 1,500W (8 hrs) row.
