VPS vs Shared Hosting Cost Calculator

Shared hosting starts at $3/month. A VPS starts at $12/month. So shared is cheaper — right? Not once you factor in backups, the cost of downtime, and the migration work you'll do when you outgrow it. This calculator gives you the real monthly number for both.

Calculate your monthly cost

How this is calculated

The formula isn't just the sticker price on the hosting page. It's the total cost of ownership per month, including the migration work you'll do when shared hosting stops being enough.

// Shared true monthly cost sharedTrue = sharedPrice + (sharedDowntimeHours × (visitors / 10000) × 5) // VPS true monthly cost vpsTrue = vpsPrice + (vpsDowntimeHours × (visitors / 10000) × 5) + (migrationHours × hourlyRate / 12) // Example: 4 hours of migration work, amortized over 12 months migrationMonthly = (4 × $50) / 12 = $16.67

The downtime penalty is a rough proxy: we assume each hour of downtime on a shared server costs you about $5 per 10,000 monthly visitors in lost conversions, trust, and SEO momentum. This comes from analyzing the actual conversion drop our clients see during outages. If you have paid ads running during an outage, the real cost is higher.

The migration cost is amortized because you do it once, but you feel it over the first year. Four hours of DNS changes, database exports, file transfers, and testing at $50/hour is $200. Divided by 12 months, that's $16.67/month — enough to make a $12 VPS feel like a $28.67 VPS.

Worked example: A WordPress blog with 15,000 visitors

Here's a real scenario we ran into recently. A client had a WordPress blog on shared hosting paying $8/month. It was hitting resource limits during traffic spikes and going down about twice a month for an hour each — roughly 24 hours of downtime per year. They were considering a $20/month VPS.

  • Shared: $8 + (24 hours × 1.5 × $5) = $188/year or $15.67/month
  • VPS: $20 + (4 hours × 1.5 × $5) + ($200 / 12) = $20 + $30 + $16.67 = $80/year or $6.67/month more than VPS sticker price
  • Real VPS monthly: $20 + $2.50/month downtime + $16.67 migration = $39.17/month

At first glance, VPS looks like $20 vs $8 — a $12 gap. But including the downtime penalty and the migration work, the gap is $39.17 vs $15.67. The VPS needs to prevent at least $23.50/month in downtime loss to justify itself. In this case, it did — the site stopped going down during traffic spikes.

Shared vs VPS: what actually changes

FactorSharedVPS
Monthly cost$3–$15$12–$60
ResourcesShared with other accounts; limited to ~25% of server[citation:11]Dedicated CPU, RAM, SSD allocation; full root access[citation:5]
Traffic ceilingTypically fine up to ~10,000 visitors/month[citation:5]Handles tens of thousands+ with proper config[citation:5]
Downtime riskHigher — "noisy neighbor" spikes can take your site offline[citation:5]Isolated environment; other users can't affect you[citation:11]
Custom softwareRestricted; provider controls the stackFull root; install anything, any PHP version[citation:11]
Email deliverabilityShared IP; reputation can be hurt by other usersDedicated IP available; better control[citation:11]
Management burdenNone — provider handles itHigher — you patch, update, and monitor (unless managed)

Frequently asked questions

How do I know when I've actually outgrown shared hosting?
The clearest signs: your site goes down during traffic spikes, pages take 3+ seconds to load consistently, or you hit resource limits in cPanel. If you're seeing any of these more than once a month, shared hosting is costing you more in lost visitors than a VPS would cost in dollars.
Is a $12 VPS actually enough for a WordPress site?
Yes, if you're comfortable managing it. A $12 VPS typically gets 2 GB RAM and 1–2 CPU cores — enough for a lightweight WordPress site with caching[citation:8]. If you have WooCommerce or 20+ plugins, budget for 4 GB RAM, which usually means $20–30/month.
How long does migration actually take?
For a single WordPress site, expect 2–4 hours of active work: exporting the database, transferring files, updating DNS, configuring the new server, and testing. If you have multiple sites or custom email, double it. If you're paying someone, that's $100–$400 depending on complexity.
Managed VPS vs unmanaged — which is worth it?
Managed VPS costs $40–$100/month but removes the sysadmin work: OS updates, security patches, server monitoring[citation:11]. If your hourly rate is above $50 and you'd spend 1–2 hours/month on server maintenance, managed pays for itself. If you're comfortable in a terminal, unmanaged at $12–$20/month is fine.
Can I just stay on shared hosting and optimize instead?
Sometimes yes. Caching plugins, image optimization, and a CDN can buy you another 6–12 months on shared hosting. But they won't fix the core problem: you're still sharing CPU and RAM with other users who can spike at any time. Use optimization to delay the migration, not avoid it forever.
