Electric blanket electricity cost calculator — daily and seasonal

Calculate with your own usage

No local tariff is supplied. Enter a rate from your bill or contract in the selected currency. This flat-rate estimate does not separately model tiers, time-of-use rates, standing charges or taxes.

Formula reviewed: 2026-09-19 · Inputs: your measurements or product labels, not an official tariff database.

Estimate electricity cost from average power and hours of use. Maximum rated power can differ from the average after temperature regulation.

Separate warm-up from normal use

Using warm-up power for an entire night may produce a poor estimate. Prefer measurements taken at your usual setting.

Enter your actual season

Reduce active months if the blanket is not used year-round. No calendar month is assumed to be summer or winter. Monthly averages include inactive months.

Illustrative calculation

60 average watts × 6 hours/day × 25 days/month × 4 months/year = 36 kWh/year. At an assumed rate of 0.2 currency units/kWh, this is 7.2 currency units/year. These are not product or tariff claims.

Check safety before cost

This tool cannot determine safe overnight use, temperature settings or product lifespan. Follow the product instructions; a low estimated energy cost is not a reason to keep using a damaged appliance.
