This calculator projects revenue the simple, reliable way: your tonnes CO2e per year, multiplied by the average value of each, multiplied by how often that value repeats across the year.
Breaking it into a monthly average makes the number easier to plan against — for staffing, capacity and cash flow — instead of a single annual figure that hides the peaks and troughs.
Change one input at a time to see which lever moves revenue most: often a small lift in repeat frequency or average value beats chasing raw volume.
Frequently asked questions
How accurate is a projection like this?
It is a planning estimate, only as good as your inputs. Use conservative averages and it becomes a dependable baseline you can compare actuals against each month.
Which lever should I focus on?
In most sustainability businesses, lifting repeat frequency or average value is cheaper than adding volume. Test each here before committing budget.
Is this calculator free to use?
Yes. It runs entirely in your browser, needs no signup or email, and nothing you enter is stored or sent anywhere.
