The real cost of a smaller phone bill.
Billing cycles, upfront charges, and the conditions behind an advertised price.
Start with the bill you actually pay
Compare plan service charges before tax, without device financing. If your bill includes payments for a phone, a smaller advertised plan price may not erase the balance still owed for that device.
Check the billing period
A $30 calendar-month plan costs $360 over 12 payments. A $30 plan renewing every 30 days has an annualized recurring cost of $365. That is 365 days divided by 30, multiplied by $30. Our calculator keeps those cycles separate.
Count the first-year costs
Activation and physical SIM fees can reduce the value of switching. A hypothetical $25 setup charge reduces a $360 first-year saving to $335. An unknown charge is excluded from our estimate and marked beside the result.
Make the conditions work for you
Automatic payments, a home-internet bundle, new-customer eligibility, or a subscription-area address can be required for an offer. Confirm the provider’s terms and coverage for the places you use your phone before switching.
