Plan A
Plan B
Total cost is the monthly price across the contract, plus any setup or modem cost, less any introductory discount. After the contract, the ongoing monthly price is what matters, so check what it reverts to. Estimate only.
For each plan the calculator multiplies the monthly price by the contract length, adds any setup or modem cost, and subtracts the total introductory discount. Comparing the two totals shows which is cheaper over the contract. A plan with a tempting discount or low monthly price can still cost more once setup fees and the full term are counted, which is exactly what this reveals.
Plan A at $89 a month over 12 months with no setup or discount is $1,068. Plan B at $79 a month is $948, plus $100 setup, less $180 of discount, about $868. Plan B is cheaper over the year despite the setup fee, thanks to the discount and lower monthly price.
