PHP 8.2, still common on business sites, loses security support on December 31, 2026. TLS certificates are shrinking too. The CA/Browser Forum voted in 2025 to cut their maximum life from 398 days to 47 days by March 2029. Both changes land on whoever maintains your website.
Website maintenance cost is the monthly spend that keeps a live site secure and working, from software updates to backups and small fixes. Redesigns and new features sit outside it. Budgets range from about $130 a month for a small brochure site to several thousand for a custom web app.
This guide gives monthly and annual budgets by site type, with the labor math shown, and explains what a maintenance plan should cover.
Website maintenance cost per month runs from roughly $130 to $260 in labor for a small brochure site and $650 to $1,300 for an online store. A custom web app needs $1,300 to $3,900. Licenses and server fees come on top, and the site’s complexity drives the range.
The labor rate comes from federal data. The median web developer earned $92,650 a year in May 2025. Wages made up 68.5% of employer cost for full-time private industry workers in June 2026, according to the BLS compensation release. That gives a loaded rate of about $65 an hour.
| Site type | Hours per month | Labor at $65/h | Labor per year |
| Brochure site, 5 to 15 pages | 2 to 4 | $130 to $260 | $1,560 to $3,120 |
| Business site with blog and forms | 4 to 8 | $260 to $520 | $3,120 to $6,240 |
| Ecommerce store | 10 to 20 | $650 to $1,300 | $7,800 to $15,600 |
| Custom web app or portal | 20 to 60 | $1,300 to $3,900 | $15,600 to $46,800 |
The hours are planning ranges for routine upkeep, and they set your website maintenance cost. A site with weekly content changes or frequent campaigns sits at the top of its band. Agency rates differ from in-house payroll, so compare quotes on hours included per month.
So how much does it cost to maintain a website once hosting is added? A small business site on managed hosting usually adds $50 to $150 a month above the labor line. That puts the full website maintenance cost near $310 to $670 a month. Online stores add app subscriptions and payment-related scanning.
A maintenance plan covers the recurring technical work listed below, plus small content changes. Each task has a schedule. A good plan writes those schedules down, so you can see what you pay for each month and spot any task that slipped.
| Task | How often | Why it matters |
| CMS and plugin updates | Weekly or as released | Closes known security holes |
| Server and PHP version upgrades | Before end of support | Unsupported versions get no security fixes |
| Off-site backups with a restore test | Daily backups, quarterly restore test | A backup you never restored may not work |
| Uptime and error monitoring | Continuous | Finds outages before customers do |
| Certificate renewal | Automated, checked monthly | Expired certificates block visitors |
| Performance checks | Monthly | Slow pages lose search rank and sales |
| WCAG 2.1 AA spot checks | Quarterly | Reduces legal risk under the ADA |
| Content and small fixes | As requested | Keeps information current |
Shorter certificate lifetimes make automation essential. Under the CA/Browser Forum’s ballot SC-081, manual renewal stops being practical well before 2029.
Performance belongs in the plan as well. Google’s Core Web Vitals set a good Largest Contentful Paint at 2.5 seconds or less. A monthly check catches regressions after updates.
Not sure what your current website maintenance cost covers?

Security and updates take up most of the website maintenance cost because they never stop. Plugins release patches every few weeks, and server software reaches end of life on a fixed calendar. Attackers scan every public site around the clock. Skipping the work saves money for a few months, then costs far more in a single incident.
Version deadlines are predictable, so plan them. PHP 8.2 loses security support on December 31, 2026, and version 8.3 follows a year later. An upgrade often needs plugin and theme testing first, so book it a quarter ahead.
Updates are only part of the job. Firewall rules and login protection need checking every month, ideally against the OWASP Top 10. The guide on how to secure a website lists the controls in more depth.
Your server choice shapes the rest. Managed hosting costs more per month but includes server patching and backups, while a self-managed cloud server costs less and moves that work onto your maintenance hours.
Maintain the site in-house when the work fills most of a developer’s week, and use an agency or freelancer when it does not. One full-time US web developer costs about $135,000 a year once benefits and taxes are added. Routine maintenance rarely needs that much time. Do the math first.
| Option | Best for | Watch out for |
| In-house developer | Large sites with steady feature work | Single point of failure during leave |
| Agency retainer | Business sites and online stores | Unused hours that do not roll over |
| Freelancer by the hour | Small sites with rare changes | Slow response during emergencies |
Many companies mix the two. An in-house marketer handles content, while an agency covers updates and emergency fixes on a retainer, which keeps the website maintenance cost predictable without a full-time hire.
A retainer is usually cheaper than hourly support for any site that changes monthly or needs fast emergency response. You trade a fixed monthly fee for reserved hours and a response-time promise, for example, 4 hours for an outage. Hourly support suits small sites that need help only a few times a year. Retainers suit the rest.
Compare website maintenance packages on four points:
Read the exclusions closely, because they decide the real website maintenance cost. Some website maintenance packages cover plugin updates but bill separately for PHP upgrades or performance work. A cheaper plan with tight exclusions can cost more over a year.
Sites that are more application than brochure need a wider view. Our guide to web app development cost covers the build side of the budget.
A website maintenance budget checklist lists every recurring line, from labor hours to an emergency reserve. Give each line a monthly and an annual figure. Then compare actual spend with the checklist every 3 months and adjust.
Add a line for accessibility. US businesses face ADA website lawsuits, and our post on ADA website compliance explains what reviewers check.
A web development agency that builds and maintains sites can price every line on this list from one review. The website project estimator gives a first range for new builds.
Want a fixed monthly plan with every task written down?
Our web team maintains business sites and online stores on clear retainers, with a monthly report of every update and check.
A small business site with a blog and forms needs about $3,120 to $6,240 a year in labor at a $65 loaded hourly rate, plus hosting and licenses. Online stores usually need $7,800 to $15,600 a year in labor, and custom web apps need more.
A small business site needs about 4 to 8 hours of upkeep a month, or $260 to $520 in labor at a loaded US rate of $65 an hour. Managed hosting adds roughly $50 to $150. Sites that change weekly sit at the top of that range.
Plugins and server software fall behind on security patches, and the risk of a hack grows each month. Certificates lapse. Backups fail silently. Cleaning up a hacked site can take 20 hours or more of emergency work, plus lost sales while the site is down.
Some plans do, within a monthly hour limit, while others cover only technical upkeep and bill content changes separately. Check how many hours are included, usually 2 to 10 a month, and whether unused hours roll over, since both change your website maintenance cost.
Plan a redesign when maintenance hours keep rising, the platform is near end of support, or the site fails Core Web Vitals after tuning. An old site on an unsupported stack can push website maintenance cost above the price of a rebuild on a current one.
