How we source onboarding cost figures
Sources, refresh cadence, in-scope and out-of-scope lists, the calculation framework, known limitations, and the corrections process. Designed so anyone challenging a figure on the site can trace it back to a named publisher in under a minute.

In scope
- Published cost-per-hire and onboarding cost bands from SHRM, Brandon Hall, Aberdeen, and NSI.
- Role-specific ramp curves from First Round Capital (engineering), Bridge Group (SaaS AE), and HBR / Watkins (executive).
- Manager-time and senior-mentor-drag modelling at 25-35% and 20-40% bandwidth respectively for 60-day windows, with BLS OEWS median wages as the dollar anchor.
- Turnover-adjusted cost per stable FTE-year derived from BLS JOLTS quit rates by industry and NSI healthcare turnover data.
- Retained executive search fee schedules from Spencer Stuart and Korn Ferry public reporting.
- Onboarding-software category framing on /onboarding-software, linked to each vendor's own pricing page (BambooHR, Rippling, Gusto, Workday, SAP SuccessFactors, Lattice, 15Five, Culture Amp). We do not invent per-seat HRIS pricing.
- BLS OEWS as the wage anchor for default calculator salary inputs.
Out of scope
- Enterprise-negotiated HRIS contracts. We use vendor public pricing only.
- Internal change-management and organisational-design cost (related but a separate cost category).
- Employer-brand value of well-onboarded employees as an intangible asset.
- Region-specific compliance training cost beyond US, UK, and EU summary bands.
- Regional payroll-tax and statutory-benefit variance below country level.
- Individual-employee productivity outliers; the calculator works in role bands, not individual predictions.
Calculation framework
The six rules of math the calculator applies. Each rule is written so the assumption set is visible; nothing is hidden behind opaque scoring.
Total = recruiting + equipment and software + training and admin + manager and mentor time + productivity ramp gap. Recruiting is typically 15-25% of the total; productivity ramp is typically the largest line item for knowledge-worker roles.
Formula: salary x (1 - average_productivity_during_ramp) x ramp_duration_in_months / 12. For a $130K engineer at 50% productivity over 9 months: $130,000 x 0.50 x 9/12 = $48,750. This is money paid without commensurate output and is usually invisible in vendor cost calculators.
Manager attention runs at 25-35% of bandwidth for the first 60 days of a new hire. Cost = manager_loaded_hourly_rate x hours_in_60_days x bandwidth_share. With a $90 per hour blended rate and 30% bandwidth, that is roughly $11,500 of manager time per knowledge-worker hire.
Senior IC time spent supporting a new engineer runs 20-40% during the first months on a codebase per First Round Capital research. Modelled at senior salary x 0.30 x ramp_fraction. For a $200K senior engineer over 3 months: $200,000 x 0.30 x 3/12 = $15,000.
For high-turnover roles (retail 60-75% annual quit rate per BLS JOLTS; sales AE 30-35% per Bridge Group; nurse 27% per NSI), expected cost per stable FTE-year = onboarding_cost x (1 + turnover_rate). This converts the per-hire number into the budget reality of replacing leavers.
Expected cost per successful long-term hire = onboarding_cost / (1 - first_year_turnover_rate). At 25% first-year attrition: every hire effectively costs 1 / (1 - 0.25) = 1.33x. At 40% (executive external placement per Spencer Stuart): 1.67x.
Refresh cadence
The verification date is held in a single constant (LAST_VERIFIED_DATE in src/lib/schema.ts). Footer stamp, schema dateModified, and visible Verified badges all read from that single source so cosmetic date bumps are not possible. The current value is May 2026.
Out-of-cycle refresh triggers:
- Annual SHRM Talent Acquisition Benchmarking Report and Human Capital Benchmarking Report refresh.
- BLS OEWS annual update and material BLS JOLTS quit-rate trend changes.
- New Gallup State of the American Workplace or State of the Global Workplace report.
- NSI Nursing Solutions annual Healthcare Retention Report.
- Material change in BambooHR, Workable, Greenhouse, Gusto, Rippling, Lattice, or 15Five public pricing.
- New published research on remote vs in-person ramp differential, executive failed-hire cost, or sales-AE time-to-quota.
Limitations
- Ranges are bands, not predictions. Actual onboarding cost depends on local labour market, role complexity, and organisation maturity that the calculator cannot model precisely.
- Vendor pricing pages drift between monthly verifications; outbound links on /onboarding-software may show numbers that have moved since the last verified label.
- Salary aggregator data (Glassdoor and similar) lags real market shifts by 6-12 months. Where OEWS and aggregator data disagree, we use OEWS as the wage anchor.
- Region-specific cost (UK, EU, India, South Africa) is summary-band only. The default calculator inputs target US mid-market organisations.
