Developer Hiring Cost Calculator
Know the True Cost of Every Engineer
Calculate the true cost of hiring engineers: interviewing time, vacancy days, agency fees, and onboarding. Most engineering teams underestimate their real cost per hire by 40% or more.

Fully-loaded cost of the engineers running your interviews
Most technical rounds run 45–75 minutes
Interviewing cost per hire: $4,320 , that's 12 candidates × 4 rounds × 1.0h × $90/hr

The Hidden Cost of Engineering Interviews
For most engineering teams, 60–70% of total hiring cost is invisible , interviewing time and vacancy days, never tracked in recruiting budgets. Finance sees a job board invoice for $3,000. The actual cost of the hire was $45,000 or more.
Interviewing time is never budgeted
When a Senior Engineer at $200K/yr spends 48 hours interviewing candidates for a single hire, that's $5,500+ in labor cost, before a single offer is made. Multiply across 10 hires and the number is staggering. It's real spend, just invisible.
Vacancy cost dwarfs job board spend
Every day a senior engineering role goes unfilled costs the equivalent of 1/250th of that engineer's annual salary in lost productivity, delayed roadmap, and team strain. At 45 days to fill, a $200K role costs $36,000 in vacancy alone.
Most TA budgets miss 2 of 4 cost categories
The typical recruiting budget tracks job board spend and agency fees. It almost never captures interviewing time or vacancy cost, the two largest categories. This creates a systematic undercount that leads to wrong hiring ROI decisions and underinvestment in speed.

Engineering hiring cost questions answered
What is included in the 'total cost per hire' for engineers?
Total cost per hire for software engineers includes four major buckets: (1) interviewing time, the cost of your senior engineers and hiring managers spending hours in technical screens, system design rounds, and panels; (2) vacancy cost, the value lost every day a role goes unfilled, typically estimated at annual salary / 250 trading days; (3) external spend, job board fees, sourcing tools, and recruiting agency fees if applicable; and (4) onboarding, ramp time, tooling, training, and new-hire productivity delay. For most engineering teams, the first two categories are never tracked in recruiting budgets, which is why the true cost consistently surprises finance teams when surfaced.
Why is the average time to fill an engineering role 45 days?
The 45-day average is an industry benchmark for software engineering roles across US companies, drawn from data published by SHRM, LinkedIn Talent Insights, and internal analyses from RPO firms. It reflects a typical pipeline that includes sourcing (1–2 weeks), screening (1 week), technical interviews (2–3 rounds over 1–2 weeks), offer negotiation (3–5 days), and offer acceptance. Highly specialized roles (Staff, Principal, and niche-stack engineers) often run 60–90 days. You can adjust the inputs in this calculator to model your actual average time to fill once you have internal data.
How does outsourcing technical interviews reduce hiring cost?
Interview as a Service (IaaS) platforms like IncServe eliminate the largest hidden cost category: internal interviewer time. When a Senior Engineer at $200K / year (roughly $115/hr fully loaded) conducts 12 technical interviews per hire across 4 rounds of 60 minutes each, that's 48 hours, over $5,500 in internal interviewer cost per hire, before factoring in disruption to their project work. IaaS replaces that cost with a fixed, predictable per-interview fee, typically producing 35–45% savings on total interviewing cost. Beyond direct cost, IaaS also speeds up scheduling (no internal calendar coordination), improves evaluation consistency, and frees your senior engineers to build product.
