What will keeping the site online cost?
Hosting is the recurring bill after the site is built. Pick what you're running and roughly how busy it is for a budgeting range — not a quote from any vendor.
How this is calculated
Each site type carries a rough monthly base range — a static site costs little to serve, a CMS needs more resources, and e-commerce or a custom app needs more still. The traffic tier scales that base up, and each add-on adds its own small range. The low and high ends are summed to give you the range shown.
These are order-of-magnitude figures for planning, not offers. Build cost is a separate line item — the one-time price to get the site made is covered inbudgeting a small-business website and estimated in thewebsite cost estimator. When you're ready to build, aweb developer can size hosting to your actual stack.
