Octopus electricity calculator

Estimate your annual electricity cost on current Octopus tariffs and compare it with what you’re paying today.

• Independent tool — not an official Octopus product
• Uses public Octopus API pricing where available
• Shows honest results when Octopus isn’t cheaper

Actual prices depend on your tariff, region, usage and eligibility. We don’t publish static “always cheaper” claims — use the calculator with your own rates.

Independent comparison tool. We may receive a referral commission if you switch to Octopus through our link.
