Total Ownership Cost Calculator
Compare the real cost of open-source vs. commercial data catalog solutions. Discover hidden costs before you commit.
Open-Source vs. Commercial: Key Cost Factors
| Cost Factor | Open-Source | Commercial (Dawiso) |
|---|---|---|
| Initial deployment | 3–6 months, dedicated DevOps team | 2–4 weeks, guided onboarding |
| Infrastructure | Self-managed Kubernetes, $2k–8k/month | Managed SaaS or on-prem, included |
| Maintenance | 1–2 FTEs for upgrades and patches | Automatic updates, zero downtime |
| Vendor support | Community forums, no SLA | Dedicated support with SLA |
| 3-year TCO (100 users) | $400k–$900k+ | Predictable, typically 40–60% lower |
What Does Total Cost of Ownership Include?
Total Cost of Ownership (TCO) for a data catalog goes far beyond the license fee. It includes infrastructure setup, ongoing maintenance, team training, integration development, and opportunity costs. Organizations that evaluate only the sticker price often underestimate the true investment by 3–5×.
Our calculator models six cost categories over a 3-year period: initial deployment, infrastructure and hosting, personnel and training, integration and customization, maintenance and upgrades, and vendor support. Each category is weighted based on data from 50+ enterprise data catalog implementations.
Why Hidden Costs Matter
According to Gartner, 60% of data catalog projects exceed their initial budget due to underestimated integration and maintenance costs. Open-source solutions often appear cost-free but require significant engineering investment: custom connector development, security hardening, upgrade management, and user training.
Dawiso's TCO calculator helps data leaders make informed decisions by modeling real-world costs across both approaches, including the personnel time that is often the largest hidden expense.
