Hourly rate comparison is just the start. A real ODC cost analysis includes overhead, management bandwidth, ramp-up time, and quality risk. Here is the complete ROI framework we share with CFOs.
Every CFO evaluating an offshore development center starts with hourly rates. That is a mistake. The true cost comparison is more complex — and when done correctly, the ODC ROI is even better than the raw rate comparison suggests.
The Naive Model (And Why It Fails)
Naive model: "A US senior engineer costs $150/hr. A Vietnam senior engineer costs $40/hr. We save 73%." Reality: this ignores setup costs, management overhead, ramp-up time, productivity curve, and quality risk.
The True Cost Components
Fully-loaded cost per engineer (US): Base salary ($180K) + benefits (30%) + office + equipment + recruiting = ~$280K/yr per senior engineer. Fully-loaded cost per engineer (Vietnam ODC): Base salary ($35K equivalent) + partner margin + operational overhead = ~$75K/yr. True savings: ~73%.
Setup and Ramp Costs
First-year costs include: ODC setup fee (one-time), legal and compliance work (~$5K), ramp-up productivity loss (estimate 60% productivity for weeks 1–6, 85% for weeks 7–12, 100% from week 13). On a 5-person team, these setup costs typically represent 10–15% of first-year savings.
The ROI Calculation
For a 5-person senior engineering team: US equivalent fully-loaded cost: $1.4M/year. Vietnam ODC fully-loaded cost: $375K/year. First-year savings (after setup): ~$800K. Year 2+ savings: ~$1.025M/year.

Best Countries to Outsource Software Development (2026 Guide)
Software development outsourcing means hiring an external engineering team - usually based in another country- to design, build, or maintain software on your behalf, instead of hiring in-house. Most US, UK, and Australian companies do this to access skilled engineers faster and at a lower fully-loaded cost than domestic hiring allows.

How to Choose an Offshore Software Development Company in 2026
Search for "offshore software development company" and you'll get the same result every time: a list. Ten names, fifteen names, twenty-five names, each with a logo and a two-line pitch, and no real way to tell which one is actually right for your project

Are Developers Becoming Too Dependent on AI Tools?
AI coding tools went from novelty to daily habit in under two years, and the tools themselves keep getting better. But using a tool every day is not the same as trusting it, and a wave of 2026 research is starting to show a real gap between feeling faster with AI and actually being better at the job. Here is what the data says, and what it means for how you build and evaluate an engineering team.
