FAQ > Billing and Payments > Why Does My Bill Vary from Month to Month?

If you notice that your V4 Consumer bill varies from month to month, it could be due to several factors. Understanding these can help you manage your account and anticipate any changes in your monthly charges. Here are the most common reasons your bill might fluctuate:

1. Usage-Based Charges

Pay-Per-Use Services: If you occasionally use services that are billed on a pay-per-use basis—such as international calls, additional data for mobile broadband, or on-demand content—these charges will vary depending on your usage each month.
Additional Services: Some services, like extra cloud storage or premium customer support, may be billed based on usage or specific needs during the month.

2. Promotions and Discounts

End of Promotional Period: If you signed up for a plan with an introductory discount or promotional rate, your bill may increase once the promotional period ends. The bill will reflect the regular price after the discount expires.
Temporary Discounts: Occasionally, you might receive a temporary discount or credit, such as a goodwill adjustment. These discounts can result in a lower bill for that month, but once they expire, your bill will return to the regular amount.

3. Changes to Your Plan or Services

Upgrades or Downgrades: If you’ve recently upgraded or downgraded your broadband plan, your bill will reflect the new pricing. The first bill after a change might also include prorated charges for the partial month at the new rate.
Added Features: Adding new features or services, such as security packages, premium support, or entertainment bundles, can result in additional charges, causing your bill to vary.

4. Billing Adjustments or Corrections

Billing Adjustments: If there were any billing errors in a previous cycle, the corrections might appear on your current bill, leading to variations.
Credits: Any credits applied to your account for overpayments or as a result of service issues will reduce your bill for that month.

5. VAT and Tax Adjustments

VAT Changes: If there are any changes to VAT rates or if a specific charge is subject to VAT in a particular month, this can cause your bill to fluctuate slightly.
Taxable Services: Some additional services or equipment rentals may be taxed differently, affecting your bill.

6. Partial Month Billing

Pro-Rated Charges: If you’ve made changes to your service mid-billing cycle, such as adding a new service or upgrading your plan, you may see prorated charges for part of the month. This can cause your bill to be higher or lower than usual depending on the timing of the change.
