5 cups/week × 25p discount × 52 weeks × 5 years: 325 saved. Cafes increasingly offer 25-50p off with reusable cups. Cup 10-20 amortised over months. Plus 130,000 fewer disposable cups per habit over 5 years.
A worked example
Try the defaults: cups per week of 5, discount per cup of 0.25, years of 5. The tool returns 325.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Cups per Week, Discount per Cup, and Years. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
The formula behind this
Weekly × 52 × years. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
Cost vs value in green choices
Sustainable options usually cost more upfront and less over time. This tool separates the two so the comparison is fair — looking at purchase price alone consistently makes the green option look worse than it is once lifetime costs are tallied.
What this doesn't capture
Carbon reduction, health benefits, and local air quality have real value the financial figure doesn't price. The calculation gives the money side honestly; for the full picture, note the non-financial benefits alongside.
What to calculate alongside this
One figure by itself is fragile. The reusable vs disposable cost calculator, the car pooling savings calculator, and the carpool savings calculator cover adjacent ground — the answer to any one of them changes how you read the output from this tool. Worth a few minutes each, honestly.
