Xfinity billing statements can show active promotional discounts and their end dates. If a promotion disappeared between statements, the bill can rise by the amount of that lost discount.
Xfinity bill guide
Why did my Xfinity bill go up?
Compare your current Xfinity statement with the previous one to isolate the charge, discount, fee, or dated change behind the increase.

What to check
Four places the increase may be hiding.
Equipment charges and other recurring service charges can change or begin applying after a promotion no longer covers them.
Taxes, government fees, and provider charges can vary by service and location. Compare the line-item totals rather than only the amount due.
One-time charges, credits, or adjustments can make one statement higher even when the recurring monthly price did not permanently change.
Statement comparison
Use the bill before the increase and the bill after it.
Use two consecutive Xfinity PDF statements. Check the discounts, recurring charges, equipment, taxes and fees, and any notices that include an effective or expiration date.

Questions
Xfinity bill increase FAQ
Why did my Xfinity internet bill suddenly increase?
A common cause is a promotional discount ending, but recurring service charges, equipment, fees, taxes, credits, and one-time adjustments can also change. Comparing consecutive statements identifies which line actually moved.
Can I see when an Xfinity promotion ends on my bill?
Xfinity statements can include promotional discounts and stated end dates. If the end date appears on a supported statement, BillDiff can use that dated information when identifying a known future change.
How does BillDiff check a Xfinity bill increase?
BillDiff compares supported consecutive statements, reconciles the previous and current totals, identifies changed line items, and checks the statement for known dated billing changes.
Does BillDiff save my original bill?
BillDiff processes the original statement for the comparison and does not save the original bill. Optional non-identifying contribution is off by default.
