Learn about partial-month charges and credits

If you change your plan or add-ons in the middle of a bill period, you’ll see partial-month charges or credits on your next bill.

Calculate your partial-month charges

For example, say you switch from a plan that costs $45 a month to one that costs $60. You make this change 10 days into your bill period.

1. Figure out the daily charge for both your old and new plans. Bill periods are always 30 days, regardless of the calendar month, so divide your monthly charge by 30.
   • Your old plan was $45 a month, which is $1.50 a day.
   • Your new plan is $60 a month, which is $2.00 a day.
2. Calculate the partial-month charges for your old and new plans. Multiply the daily charge by the number of days each plan was active during the bill period when you made the change.
   • Your old plan, at $1.50 a day, was active for 10 days, which is $15.
   • Your new plan, at $2.00 a day, was active for 20 days, which is $40.
3. Determine your partial-month credits and/or charges. We bill monthly recurring charges in advance for most plans, but bill some in arrears (afterward).
   • If you’re billed in advance: You already paid $45 for the full month of your old plan, so you’ll get a credit for the 20 days you didn’t use it. Multiply 20 days by $1.50 for a $30 partial-month credit. Your next bill will show a:
     • Partial-month credit (-$30) for the 20 days you didn’t use your old plan
     • Partial-month charge ($40) for the 20 days you used your new plan 
     • Full-month charge ($60) billed a month in advance for your new plan 
   • If you’re billed in arrears, your next bill will show a:
     • Partial-month charge ($15) for the 10 days on your old plan
     • Partial-month charge ($40) for the 20 days on your new plan 

Good to know: You can avoid partial-month charges by scheduling your new plan or add-on to start on the first day of your next bill period.
