Reduce Your Plastic Calculator

See how much plastic you save by cutting back.

Calculated Output

New plastic use (kg/yr) 28

Plastic saved (kg/yr) 12

Formula: saved = current * reduction/100

Step-by-Step Breakdown

1. Values used:

2. Current plastic use = 40 kg/yr

3. Reduction = 30 %

5. New plastic use = 28kg/yr

6. Plastic saved = (40 / 100) x 30 = 0.4 x 30 = 12kg/yr

Did this calculator solve your problem today?

The math behind it

saved = current use x reduction %; new use = current - saved.

Cutting 30% from 40 kg/year saves 12 kg — the weight of thousands of single-use bottles.

Where does most plastic go?

Over 90% of all plastic ever made has not been recycled.
