In SiteGround StartUp vs GrowBig, GrowBig is worth the upgrade if you run a second site, need staging or expect more than about 10,000 visits a month. For one small site, StartUp is enough. GrowBig costs $24.00 more in the first year ($59.88 against $35.88) and $456.00 more over four years ($1,139.52 against $683.52), because it renews at $29.99 a month against $17.99.
Prices were checked on October 15, 2026 on SiteGround’s US plan page, rates page and help center. Speed figures come from Cybernews, Mantrabrain and Website Planet tests, named below. Totals exclude taxes and domain renewals.

SiteGround StartUp vs GrowBig pricing and the real cost
| Plan | Intro price | Billing term | Paid upfront | Renewal price | Source |
|---|---|---|---|---|---|
| StartUp | $2.99/mo | 12 months | $35.88 | $17.99/mo | Official page |
| GrowBig | $4.99/mo | 12 months | $59.88 | $29.99/mo | Official page |
SiteGround’s page shows the intro price for a 12-month prepaid term and labels both plans 83% off. The paid-upfront figures are the monthly price times 12, not numbers printed on the page.
| Cost measure | StartUp | GrowBig |
|---|---|---|
| Four-year total | $683.52 | $1,139.52 |
| Average per year | $170.88 | $284.88 |
| Average per month | $14.24 | $23.74 |
| Each renewal year (years 2 to 4) | $215.88 | $359.88 |
| Websites included | 1 | Unlimited |
| Four-year cost per site, 1 site | $683.52 | $1,139.52 |
| Four-year cost for 2 sites | $1,367.04 (two plans) | $1,139.52 |
| Four-year cost per site, 3 sites | $683.52 (three plans) | $379.84 |
| Four-year cost per site, 5 sites | $683.52 (five plans) | $227.90 |
The totals are one 12-month intro term plus three 12-month renewals at $17.99 and $29.99 a month, assuming those rates stay the same. Our SiteGround renewal price guide lists both plans by renewal term. StartUp covers 1 site, so each extra site means another plan.
The gap starts at $24.00 in year one and grows to $144.00 a year at renewal, since a renewal year costs $359.88 on GrowBig and $215.88 on StartUp. Both plans bill every 12 months, so the cash difference is the size of each yearly bill. A second site is where the price flips: GrowBig for two sites costs $227.52 less over four years than two StartUp plans.
What GrowBig adds for the extra $456.00
Websites
StartUp hosts 1 website and GrowBig hosts unlimited ones, according to the plan page. If you will run a blog and a second project, or a client site next to your own, StartUp stops being an option on day one.
Staging
SiteGround’s plan and features pages list staging on GrowBig and not on StartUp, and its help center credits GrowBig with WordPress staging. Staging gives you a copy of the site to test a plugin or theme update before it reaches visitors. StartUp lists no staging tool. The steps are in how to create a WordPress staging site.
Backups
Both plans get automatic daily backups, and SiteGround’s backup help page, updated May 13, 2026, says standard backups keep up to 30 daily copies on shared hosting. The difference is on-demand backups. GrowBig gets 5 free slots, and StartUp gets them only with SiteGround’s Premium backup add-on, which adds 5 slots. The page lists no price for that add-on, so check the Marketplace before counting on it.
Resources and visits
| Limit | StartUp | GrowBig |
|---|---|---|
| Disk storage | 10 GB | 50 GB |
| Visits a month (SiteGround’s estimate) | About 10,000 | About 100,000 |
| CPU seconds a month | 300,000 | 600,000 |
| Inodes (files and folders) | 200,000 | 400,000 |
| PHP speed | Not listed | “30% faster PHP” (provider claim) |
The CPU and inode figures come from SiteGround’s fair-use page, which shows a 2021 update date, so confirm them before you rely on them. The visit figures are SiteGround’s approximations, and both plans list unlimited traffic. In practice StartUp is sized for a site below about 10,000 visits a month, and a help page for choosing a plan, which also shows a 2021 date, says a site above that will outgrow StartUp.

Support
Both plans list 24/7 expert support, free email and free site migrations. Priority support appears only on GoGeek, so support does not separate StartUp from GrowBig.
Start on StartUp and upgrade later?
You can. SiteGround’s help page says shared plans can only be upgraded to a higher plan, and that the billing cycle cannot change during an upgrade. It describes the upgrade price as the difference between the regular prices of the two plans for the time left on your term, so do not assume GrowBig’s $4.99 intro rate.
On the rates page the 12-month regular rates differ by $12.00 a month, $29.99 against $17.99. That makes an upgrade after six months an estimated $72.00, which would put the first year at about $107.88 against $59.88 for starting on GrowBig. This is an estimate from the rates page, not a quote, so read the checkout total. If you are fairly sure you will need staging or a second site within the first year, buying GrowBig first costs less.
Speed, uptime and support evidence
| Source | Method and period | SiteGround result |
|---|---|---|
| Mantrabrain | Hourly TTFB for 14 days from US East, Pingdom uptime; June 2026 | 240 ms TTFB, 99.99% uptime |
| Cybernews | Pingdom and GTmetrix; no SiteGround-specific test period stated; updated October 2, 2026 | 90 ms TTFB, 217 ms average response, 99.99% uptime |
| Website Planet | GTmetrix for one week, UptimeRobot for the monitoring period; updated June 8, 2026 | Loads in around 1 to 2 seconds, 100% uptime |
Two tests put SiteGround’s first-byte time at 90 ms and 240 ms, and all three put its uptime at 99.99% or better. None of the three pages says which plan it benchmarked, so none separates StartUp from GrowBig. Speed is not a reason to pay $456.00 more, and any speed gain from GrowBig rests on SiteGround’s own PHP claim.
Who should pick which
- One small blog or business site: StartUp, at $35.88 in year one. Expect $215.88 a year from year two.
- Two or more sites: GrowBig. Two sites cost $1,139.52 over four years, against $1,367.04 for two StartUp plans.
- A site you update often, such as a plugin-heavy WordPress site: GrowBig, for staging and 5 free on-demand backups.
- More than about 10,000 visits a month: GrowBig. SiteGround estimates about 100,000 visits for it.
- A project you will drop after a year: StartUp. $35.88 is the lowest bill and you avoid the renewal.
What would change this: if you plan to stay four years with one site and no staging, compare both against Hostinger Premium at $119.52 for the same period, which the SiteGround vs Hostinger comparison covers.
Is the SiteGround GrowBig upgrade worth it?
For most people weighing SiteGround StartUp vs GrowBig, the answer is GrowBig when you have a second site or need staging, and StartUp for a single small site that stays under 10,000 visits a month. The extra $456.00 over four years buys unlimited sites, staging, 5 free on-demand backups and 40 GB more storage.

Frequently asked questions
Can I downgrade from GrowBig to StartUp?
SiteGround’s help page says shared plans can only be upgraded to a higher plan and does not describe a downgrade. Choose GrowBig only if you are ready to keep it for the 12-month term.
Can I pay for 24 months at renewal?
The rates page lists a 24-month standard rate of $14.99 a month for StartUp and $24.99 for GrowBig. Compared with the 12-month rates, that saves $72.00 on StartUp and $120.00 on GrowBig across 24 months, but the bill is $359.76 or $599.76 at once.
What does month-to-month cost?
The rates page lists 1-month standard prices of $24.99 for StartUp and $34.99 for GrowBig. A 12-month intro term is far cheaper for the first year, which is why SiteGround leads with it.
Is migration free on both plans?
Both plans list free site migrations. SiteGround’s FAQ says your first migration is free, so ask what a second one costs before you plan to move several sites.
