The most common version of this comparison: a senior engineer in Mexico costs $75/hour through a nearshore agency. A senior engineer in the US costs $190,000 per year in salary. Therefore nearshore saves money. This calculation is missing most of the cost on both sides.

The full cost of a full-time hire

  • Base salary
  • Benefits (health, dental, vision, 401k match): typically 20–25% of base salary
  • Employer payroll taxes: 7.65% of salary up to the Social Security wage base
  • Recruiting cost: $15,000–35,000 for a senior engineer
  • Onboarding cost: 3–6 months before full productivity
  • Management overhead: typically 15–20% of a manager’s capacity
  • Equipment and tooling: $3,000–6,000 upfront plus ongoing SaaS licenses
  • A $180,000 base salary senior engineer costs approximately $240,000–$260,000 all-in per year, or $115–125 per working hour.

    The full cost of staff augmentation

  • Agency rate: $65–95/hour for a senior nearshore engineer
  • Ramp time: 2–4 weeks before full productivity
  • Management overhead: same as full-time
  • No benefits, recruiting, or equipment cost
  • No severance or offboarding cost
  • The all-in cost of a nearshore senior engineer at $80/hour is approximately $85–90/hour or $170,000–180,000 per year assuming full-time equivalent hours.

    When full-time wins

    When the engagement is long-term (2+ years), when the work is core to your product and requires deep institutional knowledge, and when you need someone to grow into leadership.

    When augmentation wins

    When you need to move faster than hiring allows, when the need is time-limited, when you need a specific skill set for a specific project, or when you are not sure yet whether the role is permanent.
