Plastic Packaging Tax Calculator

Estimate UK Plastic Packaging Tax liability from weight and recycled content.

Ad placeholder (leaderboard)

The UK Plastic Packaging Tax (PPT) charges a flat rate per tonne on plastic packaging that does not contain at least 30% recycled content, to incentivise recycled material. This free calculator works out your annual tonnage, applies the recycled-content exemption and the 10-tonne registration threshold, and computes your liability at the current rate. It also flags the separate EU Single-Use Plastics obligations. It is built for packaging procurement, finance and sustainability teams.

How it works

The calculation chains three rules:

  1. Annual tonnage = unit weight (grams) × annual units ÷ 1,000,000, or your directly entered tonnage.
  2. 30% recycled-content exemption — if recycled content is 30% or more, the packaging is chargeable at GBP 0 per tonne but still counts towards the threshold. Below 30% it is chargeable.
  3. 10-tonne registration threshold — you must register and pay only if total finished plastic packaging is 10 tonnes or more in a 12-month period.

The tax is then chargeable tonnage × £217.85. The tool shows your total tonnage, whether you cross the threshold, the chargeable tonnage after the recycled-content test, and the resulting liability. The rate of GBP 217.85/tonne applies from 1 April 2025 and is uprated yearly by CPI.

Example and notes

Suppose you import 2,000,000 trays at 25 g each with 10% recycled content. Annual tonnage = 2,000,000 × 25 ÷ 1,000,000 = 50 tonnes. That is above the 10-tonne threshold and below 30% recycled, so all 50 tonnes are chargeable: 50 × £217.85 = £10,892.50. Raise the recycled content to 30% and the chargeable amount drops to £0, though you still register and report.

The EU has no single equivalent tax — instead member states levy an own-resource contribution and apply the Single-Use Plastics Directive (product bans, marking, separate EPR). Confirm specifics per country. Everything is computed locally.
