What Does an E-Commerce Website Actually Cost to Run Per Year?

The Costs Everyone Budgets For

Domain renewal, hosting or platform subscription, and an SSL certificate if not included. These are the predictable ones, they appear on an annual calendar, and nobody is surprised by them. They're also usually the smallest part of the total.

The Cost Nobody Adds Up: Apps

This is where budgets break. Apps get added one at a time — a reviews tool, an email integration, an upsell app, a popup builder, an SEO plugin, a shipping calculator. Each looks small in isolation. A mature store frequently runs a dozen or more simultaneously, and the annual total regularly surprises owners who have never listed them together.

Do this exercise: open your billing statements and write down every recurring software charge related to your store. Most people find two or three they'd forgotten they were paying for.

Payment Processing and Platform Fees

Payment processing is typically your largest running cost and scales directly with revenue — a percentage of every transaction plus a fixed amount per order. Separately, some platforms charge their own transaction fee on top, which applies unless you use their in-house payment product. That distinction catches a lot of merchants out, because the two fees are charged by different parties and appear in different places.

• — Domain and hosting or platform subscription
• — Every app and plugin subscription, listed individually
• — Payment processing (percentage plus per-transaction fee)
• — Platform transaction fees, where applicable
• — Email and SMS marketing platforms, which price by list size
• — Development retainer or ad-hoc developer hours
• — Security monitoring and backups, if not included

The Costs That Arrive Unplanned

Things break, platforms update, and integrations stop working. A payment gateway changes its API, a plugin becomes incompatible, or a security patch needs applying urgently. Businesses without a maintenance arrangement pay emergency rates for exactly these situations, usually at the worst possible time. Budgeting a modest amount for unplanned development is more realistic than assuming a year with none.

How Platform Choice Changes the Shape

Platform-based stores carry lower upfront cost and higher recurring cost — the app stack and transaction fees compound annually. Custom-built stores carry higher upfront cost and lower recurring cost, since functionality lives in owned code rather than rented subscriptions, and there are no platform transaction fees. Neither is universally cheaper; the crossover point depends on how many apps you need and how long you'll run the site.

The Comparison That Actually Matters

Compare total cost over three to five years, not the first invoice. A store paying substantial monthly app and transaction fees for four years will frequently exceed what a custom build would have cost in total — while a small store with simple needs may never reach that crossover. Run your own numbers rather than accepting either side's general claim.
