The rule: the Ecosystem-Cost Rule.
Switching ecosystems isn’t just the price of the new phone — it’s the switching cost: repurchasing paid apps, replacing chargers, cases, and watch accessories, moving photos and messages, and weeks of relearning muscle memory.
Switch only if the savings or must-have features clearly outweigh those costs. A phone that’s $300 cheaper isn’t a deal if you spend $150 rebuying apps and accessories — and lose features you use daily, like iMessage threads or your smartwatch pairing.
Rate your lock-in honestly: 1 means you live in the browser and free apps; 5 means your watch, earbuds, tablet, and family sharing are all tied to one ecosystem.
Educational estimate only. Based on YOUR new phone cost, trade-in value, app and accessory replacement estimate, and ecosystem lock-in rating you enter. Uses the Ecosystem-Cost Rule: switch only if savings or must-have features outweigh the switching costs. Only you can weigh must-have features — this calculator can’t. Not tech advice.
