The comparison that gets presented to boards is a day rate against a salary, and it makes offshore look like an obvious win. The comparison that predicts what actually happens includes ramp time, communication overhead, retention, and the cost of decisions made slowly because the person who could make them was asleep. Sometimes offshore still wins. Often it wins for different reasons than the ones in the business case.
01Build the honest comparison
A local salary is not the cost of a local engineer. Add employer taxes, benefits, equipment, workspace, recruitment fees and the management overhead they consume. The loaded cost is meaningfully above the headline number, which narrows the gap before you have considered anything else.
On the other side, an offshore day rate is closer to a true cost - it usually includes the equipment, the workspace and some management. But it excludes your own coordination overhead, and that is the line item nobody puts in the model because it is genuinely hard to quantify.
| Cost | In-house | Offshore partner |
|---|---|---|
| Base compensation | Salary | In the rate |
| Employer taxes and benefits | Add 15-30% | In the rate |
| Recruitment | 15-25% of first-year salary | In the rate |
| Equipment and workspace | Yours | In the rate |
| Ramp time | 1-3 months | 1-3 months, still yours |
| Coordination overhead | Low | Real, ongoing, rarely modelled |
| Attrition and re-ramp | Yours | Partner's, but you re-ramp again |
02Coordination overhead is the real variable
With a fully overlapping team, a question is answered in two minutes. With four hours of overlap, it is answered the same day if asked early enough. With no overlap, every question that blocks work costs a day, and a chain of three dependent questions costs most of a week.
This is why the same offshore arrangement produces excellent results for one team and disappointing results for another. Teams that write things down, work asynchronously by default and have clear ownership barely notice. Teams that operate on hallway conversations and implicit context feel the latency on every ticket.
03Attrition is the cost that compounds
Engineers who leave take context with them, and context is where most of the value lives after month six. A team with high churn never accumulates it - you pay ramp costs repeatedly and receive the productivity of perpetual newcomers.
This is the sharpest difference between good and bad offshore arrangements, and it rarely appears in the rate. Ask any prospective partner for average tenure on their existing engagements. A partner rotating people every eight months is selling you a permanent ramp-up, however good the individual engineers are.
| Scenario | Ramp | Retention | Effective multiplier |
|---|---|---|---|
| In-house, stable team | 2 months | 3+ years | ~1.1x |
| Offshore, dedicated, low churn | 2 months | 2+ years | ~1.15x |
| Offshore, rotating staff | 2 months | 8 months | ~1.5x |
| Offshore, no overlap window | 3 months | varies | ~1.4x and slower decisions |
04The mistake that ruins the model
Treating offshore engineers as implementers who receive specifications and return code is the single most reliable way to get poor results. It creates a translation layer, so every ambiguity becomes a round trip, and it means the people closest to the code have no context about why any of it matters.
The arrangements that work treat them as engineers who own outcomes, sit in the same rituals, talk to stakeholders and are trusted to push back. That requires a real overlap window and a manager who invests in them. It costs more than the specification-throwing model and produces work of a completely different quality.
05When offshore is genuinely the right call
It works well when you need to scale faster than local hiring allows, when you need skills that are scarce or expensive locally, or when the work is substantial and long-running enough to justify the ramp. It works badly for short projects, for work requiring constant stakeholder access, and where nobody internally has capacity to manage it.
The honest framing is that offshore is a way to access a larger talent pool at a different cost point, not a way to get the same work done for less through arbitrage. Companies that adopt the first framing tend to be happy with the outcome. Those that adopt the second are usually the ones renegotiating a year later.
