Why calculate ATS ROI?
An ATS costs an average of €5,000 to €50,000 per year for an SMB. Without a numbers-driven business case, your project is unlikely to pass budget approval. The good news: a modern ATS's ROI is measurable and usually very favorable. Here's how to demonstrate it.
Step 1 — Measure current cost-per-hire
Cost-per-hire is the sum of all costs incurred to fill a role, divided by the number of hires. Three categories to add up:
- Direct costs: job board ads, agency fees, referral bonuses, paid tests
- Internal costs: HR and manager time (×loaded hourly cost)
- Opportunity cost: revenue lost while the role stays vacant
Step 2 — Identify productivity gains
A modern ATS frees up time on three measurable stages:
| Stage | Typical gain | Method |
|---|---|---|
| Resume screening | -60% to -80% | AI auto-sorting + ranking |
| Interview scheduling | -80% to -90% | Self-service candidate scheduling |
| Reporting | -70% to -90% | Native dashboards vs. Excel |
Step 3 — Quantify revenue gains
Beyond cost savings, an ATS generates indirect revenue:
- Reduced time-to-hire: each day less of an empty seat = recovered revenue. For a sales rep at €150k ARR, 10 days saved = €4,100 in revenue.
- Improved quality-of-hire: a bad hire costs 2x to 3x annual salary. Cutting probation exits by 20% saves tens of thousands of euros.
- Lower first-year turnover: better role fit extends average tenure by 6 to 18 months.
Step 4 — Build the ROI calculation
Simple formula:
Worked example: 50-person SMB growing fast
Profile: 50-person tech company in Dakar, 15 hires planned in the year, mix of tech and sales profiles.
Current annual costs (without ATS)
- Ads & job boards: €8,000
- HR time: 1 person × 60% × €35k loaded salary = €21,000
- Manager time (interviews, scorecards): 15 × 8h × €50/h = €6,000
- Opportunity cost (40-day average vacancy): €50,000
- Total: €85,000 for 15 hires → €5,667 per hire
Annual costs with Edomatch
- Edomatch license (5 users): €5,400
- Ads & job boards: €6,000 (-25%)
- HR time: 60% → 25% of time = €8,750 (-58%)
- Manager time: 8h → 4h per hire = €3,000 (-50%)
- Opportunity cost (TTH drops to 22 days): €27,500 (-45%)
- Total: €50,650 for 15 hires → €3,377 per hire
Pitfalls to avoid in your calculation
- Forgetting implementation costs (training, data migration) — typically 10 to 20% of annual license
- Overestimating year-one gains: full velocity is only reached by month 4-6
- Ignoring turnover opportunity cost: a good ATS improves retention via quality-of-hire
- Comparing sticker price without seeing what's included (AI, video, workforce) vs. add-ons
Frequently asked questions
- 01What minimum ROI justifies an ATS purchase?
- Most CFOs want to see >100% ROI over 12 months (break-even in under a year). A good SMB ATS typically reaches 300-500% in year one. If your business case shows <50%, check your assumptions — you're probably underestimating gains.
- 02How to quantify the opportunity cost of a vacancy?
- Quick method: ARR or revenue per year generated by the role ÷ 365 = daily cost of vacancy. For a €150k ARR sales rep, that's €411/day. For an engineer whose work gates a product earning €500k/year, that's €1,370/day.
- 03Does the ROI work for a micro-business under 10 people?
- If you hire fewer than 5 people a year, a paid ATS may not have positive ROI. Start with a free plan (Edomatch offers one) and upgrade once volume justifies it.
