Website Total Cost of Ownership Calculator

What this tool does

This calculator reveals the full 3-year cost of owning a website. Most people compare only the monthly hosting price and forget setup costs, plugin subscriptions, theme purchases, domain renewals, email hosting, and transaction fees. Over three years those hidden costs often exceed the hosting itself.

How to use it

• One-Time Setup Cost ($): What you pay a developer or agency to build the site, or your own time cost. DIY with a builder is typically $0-200. Professional setup ranges from $500 to $5,000+.
• Monthly Builder Plan ($): Your Wix, Squarespace, Shopify, or WordPress hosting plan. Ranges from $16/mo for basic to $299/mo for ecommerce tiers.
• Monthly Apps and Plugins ($): Recurring plugin or app costs. WordPress sites average $30-80/mo in premium plugins. Builder platforms range from $10-100/mo depending on integrations.
• Theme or Template Cost ($): One-time theme purchase. Free themes exist, but premium themes typically cost $50-200.
• Annual Domain and Email Cost ($): Domain renewal ($10-15/yr) plus professional email hosting ($6-12/mo per inbox). Total usually $80-200/yr.
• Estimated Monthly Transaction Fees ($): Payment processing and platform transaction fees for ecommerce sites. Typically 2-3% of revenue plus $0.30 per transaction.

Why it matters

A $39/mo builder plan looks cheap until you add 3 years of apps ($1,620), transaction fees ($2,880), setup ($800), domain and email ($360), and a theme ($250). The real 3-year cost is $6,802, not $1,404. Comparing builders on monthly price alone leads to expensive surprises 18 months later.

How to use the result

Run the calculator for each builder you are considering. The one with the lowest monthly plan often does not have the lowest 3-year total once plugins and transaction fees are included. Pay special attention to transaction fees if you run an ecommerce site: they scale with revenue and become the largest cost component.
