What will a new iPhone 7 cost you?

The new iPhone 7 will go on sale Friday. If you plan to buy one, where should you buy it and what plan should you select?

WalletHub, a personal-finance website, is offering its “iPhone Savings Report” to help consumers examine the different pricing options and find the best deal.

It used its Cell Phone Savings Calculator to compare the different ways that consumers can purchase the iPhone, evaluate coverage plans, and figure out when consumers are better off keeping their current phone.

WalletHub found:

• Individual consumers who want the new iPhone can save up to $1,074 by choosing a no-contract plan from RingPlus Mobile over the same types of plans from T-Mobile and Verizon.

• Individual consumers can save up to $1,324 by keeping their old phone and getting coverage from the Walmart Family Mobile.

• Families can save up to $1,705 for four lines with 12GB of data by choosing a no-contract plan from RingPlus Mobile over an Apple installment plan from AT&T for $4,694.

• Families can save up to $2,294 by keeping their old phones and getting coverage from RingPlus Mobile.

The calculator allows consumers to put in their upfront and monthly costs to directly compare the cost of two-year contracts, installment plans, and no contract plans from the major carriers.

Below is WalletHub’s infographic comparing plans offered by AT&T, Sprint, T-Mobile, and Verizon.
