How do you calculate packaging tax exposure?

Multiply taxable tonnes by the per-tonne rate by the below-threshold share, then add filing overhead. For 200 tonnes at $260, 60% below threshold and $3,000 overhead, total exposure is $34,200.

What is the effective tax per tonne?

It is the total exposure divided by total taxable weight, including fixed overhead. In the worked example $34,200 over 200 tonnes gives $171 per tonne, higher than the pure variable rate because overhead is spread across the weight.

How does recycled content reduce packaging tax?

Tonnage at or above the recyclate threshold is not taxed. Lowering the below-threshold share from 60% to, say, 30% roughly halves the variable liability, which is why recycled-content investment pays back directly.

What is the difference between variable and fixed tax cost here?

Variable cost is the tax on below-threshold tonnage ($31,200 in the example); fixed cost is the $3,000 filing and compliance overhead that applies regardless of tonnage.

What is a good packaging tax exposure per tonne?

The floor is set by your filing overhead spread across weight; the goal is to drive the effective rate toward zero by pushing tonnage above the recyclate threshold. $171/tonne here is dominated by the 60% below-threshold share.

Packaging tax exposure vs full lifecycle cost — which do I use?

Tax exposure is one line in the broader lifecycle cost. Use this calculator to size the specific tax liability, and the lifecycle cost calculator to see it alongside material, conversion and end-of-life costs.

Sustainable Packaging & EPR Compliance calculator

Packaging Tax Exposure Calculator

Packaging Tax Exposure estimates your liability under a plastic packaging tax by applying a per-tonne statutory rate to the share of tonnage that falls below the recycled-content threshold, then adding the fixed filing and compliance overhead. Finance and sustainability teams use it to forecast the cost of packaging that doesn't meet minimum recyclate rules — for example the UK Plastic Packaging Tax's 30% recycled-content threshold. The below-threshold percentage is the lever a redesign moves: lift recycled content above the threshold and that tonnage drops out of the taxable base. The effective per-tonne figure shows the true burden once fixed overhead is spread across your weight.

What this calculator does

Estimate plastic-packaging tax exposure on tonnage falling below recycled-content thresholds.
A finance or compliance lead forecasting plastic packaging tax liability and the savings from raising recycled content.
It multiplies taxable weight by the per-tonne rate and the below-threshold share, adds filing overhead, and divides by weight for an effective rate.

Formula used

Total tax exposure = taxable weight x tax rate x taxable% + filing overhead
Effective tax per tonne = total / taxable packaging weight

Inputs explained

Taxable packaging placed on market:
Statutory tax rate per tonne:
Share of tonnage below the recyclate threshold:
Annual filing and compliance overhead:

How to use the result

Use it to forecast plastic packaging tax liability and model how raising recycled content shrinks the taxable base.
It uses one flat rate and one below-threshold share; real filings vary rates by material and require documented recycled-content evidence per component.
