AT&T 24-month deal: what it really costs

AT&T's 24-month version shortens the same Extra 2.0-tied credit promo by a year, which changes the arithmetic more than the mechanics: the same phone's financed cost gets divided into 24 installments instead of 36, so each month's required bill credit is larger to still land at zero by the end of the term.

The requirement

This deal requires the Extra 2.0 plan, at $50 a month, held for the full 24-month term. Against US Mobile Unlimited Starter at $22.50 a month, that required tier alone adds $660 over the term, before any device credit is counted.

The Extra 2.0 requirement carries over unchanged from the 36-month version, and so does the all-or-nothing forfeiture on early exit. What differs is the exposure window: a customer who has already reached the back half of a 24-month term has banked a larger share of the promo's total credit value than someone at the same number of months into a 36-month term, since the 24-month schedule pays out the full credit over fewer months.

Not in these numbers

AT&T Extra 2.0 at $50 a month requires autopay and paperless billing, and is stated before taxes and fees. US Mobile Unlimited Starter at $22.50 a month does not require autopay, and is stated with taxes and fees included.

Taxes and fees, where a plan price is not taxes-inclusive
They vary by state and by line, so any single figure here would be wrong for most readers.
Promotional eligibility and credit-check tier
Carriers set both per customer, and a failed check changes the deal entirely.
Whether a trade-in passes inspection
A downgraded appraisal cuts the credit after you have already shipped the phone.
Line-count and bundle discounts
They depend on the rest of the account, not on the phone you are buying.
Autopay and paperless-billing requirements
Advertised plan prices usually assume both; losing them raises the monthly figure.
Device insurance and protection plans
Optional on both paths, so including them would change both totals equally.
