When is the right time to upgrade your gadget?
Traditional upgrade decisions only look at whether the new device is worth it financially, ignoring environmental cost. This tool calculates both financial break-even and carbon payback time for a more complete picture.
How is the financial analysis calculated?
We compare the monthly depreciation loss + repair costs of your current device against the new device price amortized over its expected lifespan to find the financial break-even point.
Why does carbon matter?
Manufacturing a new device consumes significant carbon. If your current device's degraded efficiency causes extra power consumption, upgrading can pay back that carbon over time. All estimates are transparently sourced.
