Why did my bill go up?
US consumer guidance
What to do
Match the billing dates, find the changed line and ask your provider which term explains it.
- Compare the same billing period.
- Separate service, usage, credits and one-time items.
- Check the offer or renewal notice you accepted.
- Ask about the exact line you cannot explain.

How much did it change?
Enter two totals to compare.
Use matching periods and the same currency. This shows the difference, not whether a charge is correct. Nothing is sent or saved.
Explain the gap
Add changes you have found on the bill. Use minus amounts for decreases. These are your entries, not detected causes.
Compare two totals first.
Then see how much of the difference your entries account for.
Message template
Replace the brackets with your details. Send through the business’s verified support channel.
My [service] bill changed from [previous total] to [current total] for [billing dates]. The line labeled [exact label] changed by [amount]. My written offer says [relevant term]. Which rate or term explains this line, and can you link the applicable notice?
Step-by-step detail
01Compare the same period
Check the start and end dates on both bills. Note a longer period, a balance carried forward or a one-time adjustment separately. Mark changes in service or usage. Keep private copies of the documents you compare.
02Separate the moving parts
Make three columns: recurring service, usage-based charges and one-time items. Record credits separately. For each change, write the label exactly as it appears and the difference in amount. A different label does not by itself explain a charge.
03Check the written offer
Find the price period, renewal date and exclusions in the agreement you accepted. A subscription promotion can end at renewal. The FTC advises checking renewal prices and contacting the business when the cost differs from your expectation. Keep any renewal notice with the offer.
04Ask about the unresolved line
Choose the line you cannot explain. Ask the provider for the period, rate or term behind it and the document that supports it. Save the dated response. For a suspected unauthorized charge, promptly use your payment provider’s official dispute process; this comparison does not replace that process.
