Staff Augmentation ROI Calculator
Compare the fully-loaded cost of hiring in-house against staff augmentation, by seniority tier, headcount, and engagement type — then read the methodology to see exactly what's being compared and what isn't.
Compare Your Costs
The methodology behind this calculator
This calculator compares two costs over the same engagement period: the fully-loaded cost of an in-house hire, and the billed cost of a staff-augmented engineer at a comparable seniority tier. Fully-loaded in-house cost is calculated as base salary × 1.35 — within the commonly cited 1.25x-1.4x range that accounts for employer payroll taxes, benefits, equipment, office overhead, and standard recruiting cost, not base salary alone. Comparing an augmented hourly rate against base salary alone understates in-house cost and makes the comparison misleading in favor of augmentation — this calculator deliberately avoids that shortcut.
Augmented cost is calculated as hourly rate × 160 hours/month (a standard full-time-equivalent month) × engagement duration × headcount. The three engagement-type rate bands used here — offshore (~$35/hr), nearshore (~$50/hr), and onshore contractor (~$90/hr) — reflect typical blended senior-engineer rates for each category; actual rates vary by specific country, specialization, and staffing partner. Industry data puts realistic engineering cost reduction from staff augmentation at 35-60%, with the low-to-mid end of that range typical at nearshore rates and the high end typical offshore — this calculator's default scenario lands around 50%, consistent with that range.
Why fully-loaded cost, not base salary, is the right comparison
A $150,000 base-salary engineer costs an employer roughly $187,500 to $210,000 once payroll taxes, benefits, and overhead are included — the loaded-cost multiplier this calculator uses (1.35x, landing at $202,500 for this example) sits within that commonly cited range. Comparing a $50/hr augmented rate against a $150,000 base salary alone (roughly $72/hr at 40 hours/week, 52 weeks) understates the real savings; comparing it against the true $202,500 fully-loaded cost (roughly $97/hr) shows the actual gap — around half the cost at nearshore rates, more at offshore rates. This distinction is where most informal cost comparisons go wrong, and why quoting savings against base salary alone is misleading in either direction.
Recruiting cost is a real but harder-to-standardize addition on top of the loaded multiplier — external recruiter fees commonly run 15-25% of first-year salary for a direct hire, a cost staff augmentation avoids entirely since there's no placement fee. This calculator doesn't add that cost by default since it varies by whether an internal recruiting function or an external agency is used, but it's a real additional gap in augmentation's favor for any role requiring recruiter involvement.
What this comparison doesn't capture
- Time-to-fill cost — a technical hire commonly takes multiple months to source, interview, and onboard; a delayed project has real cost this calculator doesn't quantify, since it varies enormously by role and market
- Retention and institutional knowledge — for genuinely permanent, long-duration needs, an in-house hire who stays for years builds context an augmented engineer rotating off an engagement doesn't accumulate the same way
- Output variability — this calculator assumes comparable hourly output at a given seniority tier; verify the specific engineers proposed actually match the seniority and domain experience the rate tier implies
- Team cohesion and management overhead — a large augmented team requires real coordination and oversight from your side, a cost that scales with headcount and isn't purely a dollar figure
Why the savings don't come at the cost of quality
A large gap between in-house and augmented cost naturally raises the question of what's being traded away. The honest answer for a well-vetted staffing partner is: not engineering seniority. Rate differences between offshore/nearshore and onshore markets reflect cost-of-living and local salary economics, not a difference in skill — the same senior engineer who could pass a FAANG-tier interview loop commands a much lower dollar rate in a lower-cost-of-living market for the same output. The risk isn't the rate tier itself; it's an unvetted staffing partner that doesn't actually deliver the seniority a rate tier implies.
This is why the engineering process behind the augmented team matters as much as the rate. Code Ninety staffs engagements exclusively with senior engineers, operating under CMMI Level 5 and SOC 2 Type II-certified delivery processes — the same process rigor used across our full-scope development work, not a stripped-down process for augmentation clients. The cost gap this calculator shows is real; it exists because of where the engineering talent is based, not because of a quality tier being sacrificed to hit the price point.
When in-house hiring wins despite the cost gap
This calculator will almost always show augmentation as cheaper on a pure dollar basis, especially at offshore/nearshore rates — that's a mathematical fact of the rate spread, not a universal recommendation. In-house hiring remains the better choice when the role is genuinely permanent and central to the product's long-term direction, when deep institutional knowledge compounds in value over years, or when the team is small enough that culture and direct ownership matter more than marginal cost. Staff augmentation wins most clearly for time-boxed initiatives, specialized skills needed for a defined period, and situations where a multi-month hiring cycle would delay the project more than the cost differential is worth.
What Code Ninety does
Code Ninety provides staff augmentation and embedded engineering teams at nearshore-comparable rates, staffed exclusively with senior engineers who work under your technical direction inside a CMMI Level 5, SOC 2 Type II-certified delivery process — using the same fully-loaded cost comparison this calculator is built from to help clients make an honest build-vs-augment decision rather than a rate-only one. Code Ninety is an IT company in Islamabad with a 250-plus engineering team.
Frequently asked questions
What is the fully-loaded cost of an in-house engineer?
Fully-loaded cost is base salary plus benefits, payroll taxes, equipment, office overhead, and recruiting cost — typically 1.25x to 1.4x base salary in the US. A $150,000 base-salary engineer typically costs $187,500 to $210,000 fully loaded, which is the number that should be compared against an augmented rate, not the base salary alone.
Is staff augmentation always cheaper than hiring in-house?
Not always — for a permanent, long-duration need where retention and deep institutional knowledge matter most, in-house hiring can be the better long-term investment despite the higher fully-loaded cost. Staff augmentation wins clearly for time-boxed engagements, specialized skills needed briefly, and roles where a multi-month hiring cycle would delay the project more than the cost differential matters.
What's the real cost of a slow hiring cycle, beyond salary?
A technical role left unfilled for months means delayed delivery, other team members covering the gap at reduced velocity on their own work, and in competitive markets, the risk of losing the best candidates to faster-moving employers. This calculator doesn't quantify that cost directly since it varies enormously by project — but it should weigh into the decision alongside the direct dollar comparison.
How do augmented developer rates vary by engagement type?
Offshore engagements typically run $25-45/hr for a senior engineer, nearshore $45-70/hr, and onshore contractors $80-120/hr, depending on specialization and market — all well below the $91-97/hr typical fully-loaded cost of a US in-house senior hire. The gap versus fully-loaded in-house cost narrows as you move from offshore toward onshore, so the right tier depends on how much of the savings is actually needed versus how much real-time overlap the project requires.
Does this calculator account for productivity differences?
No — it assumes comparable output per hour between an in-house hire and an augmented engineer at the same seniority tier, which is a reasonable assumption for a well-vetted staffing partner but not guaranteed. Verify the specific engineers proposed have the seniority and domain experience the rate tier implies before assuming equivalent output.
Does a lower rate mean lower engineering quality?
Not with a well-vetted partner — rate differences between offshore/nearshore and onshore markets reflect cost-of-living economics, not skill differences. The risk isn't the rate tier; it's an unvetted staffing partner that doesn't actually deliver the seniority the rate tier implies. Verify the partner's delivery process and certifications, not just the headline rate.
Should I use staff augmentation or a fixed-scope project instead?
Staff augmentation suits ongoing, evolving work where you need embedded capacity under your own technical direction. A fixed-scope engagement suits well-defined projects with clear deliverables where you want a vendor to own outcomes, not just provide capacity. See our RFP template for structuring a fixed-scope engagement instead.
