Email Hosting: Real Cost
Professional email on your own domain costs anywhere from nothing for basic free-tier services with usage limits to a meaningful annual sum per mailbox on full-featured platforms. The real cost depends on how many mailboxes you need and what the per-user rate is after any promotional pricing ends. This calculator shows the honest multi-year total.

Year 2 costs more than year 1. That is the renewal, not a price rise — it was in the terms when you signed up.
Totals assume the renewal price holds and no plan change. Hosts do raise renewal prices between terms, so treat this as the floor of what the years ahead cost, not a quote.

Why Email Costs Creep Up Quietly
Most small businesses start with one or two email addresses and a low per-mailbox rate. As the team grows, each new hire adds another monthly charge. Over three years with five mailboxes, email hosting can exceed the cost of the web hosting itself, a reality that surprises business owners who budgeted only for the domain and a hosting plan.
Free-tier email services exist with limits: a cap on the number of mailboxes, restricted storage per account, or branding in outgoing messages. These work for a sole trader or a tiny team. The moment you need more than the free tier allows, the jump to a paid plan applies to every mailbox, not just the new ones.
Bundled email from your hosting provider is another path. Some hosting plans include email accounts at no extra charge, but the storage and features are often basic compared to a dedicated email hosting provider. Evaluate what you are getting before assuming it covers your needs.
What the Calculator Shows
Enter three values: the number of mailboxes you need now, the monthly per-mailbox price, and any promotional discount that applies to the first term. The calculator returns your email hosting cost at one year, three years, and five years, including the rate change after the promotional window closes.
Use it to compare scenarios. Run the numbers for a free-tier provider with the maximum included mailboxes, then a mid-range paid plan, then the premium option. The three-year column reveals which approach is genuinely cheaper once promotional pricing expires and per-user fees stack up across your team.
If you are still deciding whether you even need email on your own domain versus using a generic provider, start with the total website cost breakdown to see where email fits in your overall budget. The numbers matter more than the branding pitch.
Email provider pricing can change at renewal. Verify current per-mailbox rates on the provider's pricing page before committing to a multi-year comparison.
