Answer · Cost & Scope
Is a custom WordPress theme worth it vs Elementor / Divi?
Five-year TCO comparison from real engagements. The honest answer.
Five-year TCO comparison from real engagements. The honest answer.
The premise
Compare the same site shape — six templates, two locales, a B2B service business — built three ways. Numbers come from twelve real engagements where I either built the replacement or audited the existing.
| Year 5 TCO | Elementor / Divi | Custom theme |
|---|---|---|
| Initial build | $3,500 | $18,000 |
| Maintenance | $8,400 ($140/mo) | $24,000 ($400/mo) |
| Performance debt | $6,500 (one rescue) | $0 |
| Accessibility retrofit | $4,200 | $0 |
| Vendor change cost | $8,000 (avg) | $0 |
| 5-year total | $30,600 | $42,000 |
What the table hides
The $30,600 column is a slow-motion crisis. Three perf rescues, one retrofit, one panic when the page builder ships a breaking change. The $42,000 column is a flat monthly line; everything is in the budget from day one.
When the page builder wins
One-off campaign sites. Internal tools. Sites you’d actually be happy to rebuild in two years. For long-haul B2B marketing sites, custom theme wins on every dimension except day-one cash.
