Based on 2 swaps across 1 person. Figures are directional averages, not precise measurements — your prices, habits and local recycling all shift the result.

How to sequence these

  1. Start with the swap you repeat most often — frequency beats symbolism.
  2. Use what you already own until it fails. Buying a "sustainable" duplicate is a net loss.
  3. Add one swap per month so each becomes a habit before the next arrives.
  4. Re-run this calculator in three months and keep only what actually stuck.
