Website Maintenance Cost Calculator
Hosting, domains, updates, certificates — calculate your annual total
Site complexity is the single biggest driver of maintenance cost — e-commerce and SaaS sites require 3–5x more ongoing work than a simple landing page due to integrations, security surface area, and user data handling.
E-commerce and web apps carry payment integrations, user accounts, and legal compliance — each adds recurring maintenance effort regardless of how rarely the design changes.
Hosting is not just a line item — the wrong plan causes slow load times, security breaches, or surprise overage bills. Shared hosting saves money upfront but one noisy neighbour can tank your site's performance.
VPS gives you dedicated CPU and RAM — critical for sites with 500+ daily visitors. Cloud (Vercel/Cloudflare) auto-scales and eliminates server administration, making it cheaper than VPS at moderate traffic levels.
43% of cyberattacks target small businesses, and the average cost of a data breach in Europe is €4.45M (IBM 2023). Spending 100–400 PLN/mo on security typically prevents incidents that cost 10,000–100,000 PLN to remediate.
Daily backups add ~30 PLN/mo but a single data loss event can cost 10–100x more in recovery and downtime. Weekly backups mean you can lose up to 7 days of content, orders, or customer data.
80% of WordPress hacks target outdated plugins or missing WAF rules. Advanced protection (WAF + malware scanning) blocks most automated attack traffic before it reaches your server.
Unpatched dependencies are the root cause of 60% of known exploits. Monthly updates reduce exposure windows; weekly updates are recommended for sites handling payments or personal data.
Every extra week between updates is an extra week a known vulnerability stays open. Critical security patches are released on average 4–6 times per month across common CMS and npm ecosystems.
Regular content updates improve SEO ranking by 30-50%
Sites that track keyword positions and run quarterly technical audits recover from Google algorithm updates 2–3x faster than those that rely on passive monitoring alone.
GDPR fines in 2024 averaged €1.2M per violation. WCAG accessibility compliance is becoming mandatory in the EU under the European Accessibility Act (2025). Proactive compliance is far cheaper than remediation.
Each integration adds a recurring maintenance cost — API updates, authentication changes, and data sync issues require regular attention. The average site uses 5-10 third-party integrations.
Average response time directly correlates with downtime cost — 1 hour of downtime costs e-commerce stores 500–5,000 PLN on average, making faster SLA tiers a measurable business investment.
A 48h email SLA means a critical bug discovered Friday evening stays live until Monday morning. Priority (4h) or 24/7 (1h) support is strongly recommended for any revenue-generating site.
Each hour is billed at 150 PLN — a retainer of 5h/mo covers small fixes and minor features. Without a retainer, ad-hoc requests are typically billed at a higher one-off rate.
