What does the right-to-repair score measure?

It measures how easily a product can be repaired across the factors regulators focus on: whether spare parts are available and affordable, whether repair instructions are published, how deeply the device must be disassembled to reach common failures, whether ordinary tools suffice, and how long software and security updates are provided.

How is the weighted score calculated?

Each factor is rated 0 to 10 and multiplied by its weight. The weighted ratings are summed and divided by the sum of the weights, then scaled to a 0 to 100 index. This mirrors the approach of repairability indices, where the most impactful factors, such as spare-parts and disassembly, carry the largest weight.

Which laws does this relate to?

It reflects the EU Ecodesign for Sustainable Products framework and product-specific Ecodesign regulations that mandate spare-parts availability and repair information for goods such as appliances, displays, and electronics, along with the EU Right to Repair Directive and comparable UK measures. National details vary by product group.

What software-support duration should I aim for?

Longer is better and increasingly mandated. Regulators are pushing minimum security-update periods measured in years beyond the last unit sold. A device whose hardware is repairable but is bricked by an end of software support has poor real-world longevity, which is why software is a scored factor here.

Is the score an official repairability index?

No. It is an internal design and triage aid that approximates the regulatory factors. The official French repairability/durability indices and any product-specific Ecodesign scoring use prescribed sub-criteria and formulas. Use this to compare design options early, then validate against the binding methodology.

Right-to-Repair Product Scorer

Right-to-repair rules increasingly require manufacturers to make products repairable: spare parts must be available, instructions published, and devices designed so common failures can be reached without specialist tools. This scorer turns those factors into a single weighted repairability index so you can compare designs and spot gaps before launch.

How it works

Five factors are each rated 0 to 10 and combined with weights:

factors: spare parts, documentation, disassembly depth,
         tool requirements, software/support duration

score (0–100) = Σ(rating × weight) / Σ(weight) × 10

Spare-parts availability and disassembly depth carry the heaviest default weights because they most directly determine whether a repair is even possible. The lowest- scoring factors are surfaced so remediation effort goes where it moves the index most.

Notes and tips

A high hardware score is undermined by short software support — a phone you can open in two minutes is still e-waste once security updates stop, so treat the software factor as first-class. Aim for spare parts that are both available and affordable relative to the new product price; regulators look at price as well as existence. This index is a design-stage triage aid, not the official Ecodesign or French repairability/durability index — validate against the binding methodology for your product group.
