How it works
Total = upfront + monthly × months
A lower monthly price can lose to a plan with a device subsidy once you add the upfront cost and multiply over the contract. Comparing full totals over the same period settles it.
Worked example
$60/mo with $0 upfront over 24 months is $1,440; $40/mo with $200 upfront is $1,160 — Plan B wins.
Frequently asked questions
What period should I use?
Use how long you will realistically keep the plan or device — 24 months is common for contracts.
What about data limits?
This compares price only. Weigh data, coverage and perks alongside the totals.
