Recycling Rate Calculator: Recycled as a Share of Total Waste
Work out a recycling (diversion) rate from the amount recycled and total waste — the standard sustainability metric for households, businesses, schools, and municipalities, with the landfilled share shown alongside.

Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Recycling rate | Sent to landfill |
|---|---|---|
| 350 of 1,000 (35%) | 35.00% | 65.00% |
| 500 of 1,000 (50%, target) | 50.00% | 50.00% |
| 900 of 1,000 (90%, zero-waste) | 90.00% | 10.00% |
| 120 of 1,000 (12%, low) | 12.00% | 88.00% |
How This Calculator Works
Enter the amount recycled or diverted and the total waste generated, in the same unit (usually weight). The calculator divides one by the other and multiplies by 100 to give the recycling rate, with the share sent to landfill shown alongside.
The Formula
Part as a Percentage of a Whole
Part is the portion, Whole is the total it belongs to
Worked Example
350 units recycled out of 1,000 total is a 35% recycling rate, with 65% going to landfill. Recycling rates are measured by weight and used at every scale — households tracking their own diversion, businesses and schools pursuing waste-reduction goals, and municipalities reporting performance. National and city rates vary widely; many places target 50%+ diversion, and 'zero waste' programs aim for 90%+. The rate is a useful headline, but what's recycled and whether it's actually processed matter as much as the percentage.
Key Insight
Recycling rate is a clean ratio, but interpreting it well requires looking past the headline number. First, contamination undermines it: materials placed in recycling that are dirty, non-recyclable, or mixed can cause whole loads to be rejected and landfilled, so a reported recycling rate can overstate what's actually recycled — keeping recyclables clean and sorted matters as much as the rate. Second, the waste hierarchy ranks reduce and reuse above recycling, so a high recycling rate isn't the whole story — generating less waste in the first place beats recycling more of it. Third, the rate is usually by weight, which can flatter or distort: heavy materials (glass, metal) dominate a weight-based rate, while light but high-impact items (plastic film, electronics) show up small even when they matter environmentally. For tracking improvement, measure consistently (same unit, same scope of what counts as 'diverted'), set a target appropriate to your context, and pair the rate with reduction efforts. Composting and reuse count as diversion in many definitions, so clarify what's included. The complement — the landfilled share — is the part to drive down, and the most effective lever is often reducing total waste, not just recycling a bigger fraction of it.
Frequently Asked Questions
How is the recycling rate calculated?
Divide the amount recycled or diverted by the total waste generated, then multiply by 100. 350 units recycled out of 1,000 total is a 35% recycling rate, with 65% sent to landfill. It's usually measured by weight.
What's a good recycling rate?
It varies by context and scale. Many municipalities and organizations target 50%+ diversion, and 'zero waste' programs aim for 90%+. National and city rates differ widely. Compare against your own trend and relevant benchmarks rather than a single universal figure.
How does contamination affect the rate?
A lot. Recyclables that are dirty, non-recyclable, or mixed can cause whole loads to be rejected and landfilled, so a reported recycling rate can overstate what's actually recycled. Keeping recyclables clean and properly sorted matters as much as the headline percentage.
Is a high recycling rate the main goal?
Not entirely. The waste hierarchy ranks reducing and reusing above recycling, so generating less waste in the first place beats recycling more of it. A high recycling rate is good, but pairing it with waste reduction is better — the most effective lever is often producing less total waste.
Why does measuring by weight matter?
Because heavy materials (glass, metal) dominate a weight-based rate, while light but environmentally significant items (plastic film, electronics) appear small even when they matter. A weight-based rate can flatter or distort the picture, so consider what materials make up your waste, not just the percentage.

Methodology & Review
The recycling rate is recycled (diverted) material divided by total waste, multiplied by 100. The complement is the share not diverted (landfilled/incinerated). It's typically measured by weight and does not distinguish material types or account for contamination that may render recyclables unusable.
