Cheapest domain extensions by registration price

First-year registration price is useful when you need a temporary test domain, a short campaign URL, a staging project, or a side-project name that may not renew. It is less useful for brand domains because many low first-year offers renew at a much higher rate.

The table below uses live TLDPrice data from 13 registrars and 1538 active extensions. Open any TLD page to compare the full registrar list, renewal column and transfer column.

Cheapest domain extensions by renewal price

Renewal price is the better metric for a domain you plan to keep. A $1 first-year promotion can become expensive if renewal is $25 to $40 every year, while a domain with a slightly higher first-year price and a stable renewal can be cheaper over three to five years.

How to choose a cheap extension without overpaying later

Five-year cost example

A practical way to compare cheap extensions is to ignore the headline promo and calculate total ownership. Use this simple formula:

Cheap domain extensions vs cheap registrars

These are different decisions. The extension controls the registry cost and audience expectation; the registrar controls markup, privacy options, DNS tools, support and checkout experience. A low-cost extension at an expensive registrar can still be a bad deal, while a mainstream extension at a low-markup registrar can be cheaper over time.

Use the registrar comparison page to compare providers, then use a TLD page such as .com prices, .xyz prices or .online prices to compare exact registration, renewal and transfer rows.

When a cheap extension is the wrong choice

• Email-heavy projects: unfamiliar TLDs can reduce trust in cold outreach, support emails and invoices.
• Long-term brands: a cheap first year matters less than memorability, renewal stability and defensive registration needs.
• Investor portfolios: renewal math matters across hundreds of domains, and some promos have limits or special renewal rules.
• Transfer plans: ICANN transfer rules can affect timing, so compare transfer price before a renewal deadline and leave enough time to move.

Checklist before buying a cheap domain extension

1. Open the TLD page and compare at least three registrars.
2. Check registration, renewal and transfer prices separately.
3. Calculate the three-year or five-year ownership cost.
4. Confirm whether WHOIS privacy, DNS management and email forwarding are included.
5. Verify final checkout price on the registrar site because promos, taxes and regional fees can change.
6. Set a calendar reminder before renewal if the first-year price is promotional.
