Most articles about the hidden costs of web hosting list six add-ons and miss the one that actually costs the money. Here they all are, largest first.
1. The renewal jump — by far the biggest
Everything else on this page is rounding error next to it. Across the sixteen hosts we have reviewed the renewal price averages 3.5x the intro rate. On SiteGround's entry plan that is $2.99 becoming $17.99, which over three years adds roughly $360 compared with a host that holds its rate. No add-on on this list comes close. Every host ranked by the real total.
2. Domain renewal
Free for the first year at most hosts, then $10 to $20 annually. Genuine, unavoidable, and small.
3. Email hosting
Once bundled, now increasingly a separate product at around $0.39 to $2.95 per mailbox per month — see email hosting compared per mailbox. For a business with five staff that is a real line item.
4. Backups
Bundled by some hosts, a monthly add-on at others, and occasionally a fee to *restore* rather than to store. Check the restore terms, not just the backup terms. This one is worth paying for wherever it is not included.
5. SSL certificates
Should be free everywhere by now. Free certificates are standard and adequate for almost every site; a host charging for basic SSL in 2026 is charging for something it gets for nothing. Paid certificates exist for specific validation needs, which most sites do not have.
6. Migration
Free at most hosts, chargeable at a few, and worth checking before you commit rather than after. Two of the four host-to-host moves we have written up have a destination that charges.
7. Dedicated IP addresses
Usually a few dollars a month, and usually unnecessary. The old reason for buying one — SSL required it — has not applied for years.
The rule that covers all of it
Total the whole term before you buy, not the first month: the true cost calculator includes the domain assumption and shows its working. And read how to avoid a renewal increase, since that is where the actual money is.
