What Data Annotation Costs in 2026
Short answer: data annotation costs anywhere from $0.01 per simple image label to $300 per hour for credentialed experts. Managed services bill from about $6 per annotator hour for commodity work; per-image fees run $0.01–$5.00; expert RLHF and evaluation work bills at $60–$125+ per hour. The single most common pricing confusion in this market is mixing up what annotators are paid with what clients are charged — this page keeps them separate.
What clients are charged (published figures)
- Per image: $0.01–$5.00 per annotated image, depending on complexity (BasicAI, “How Much Do Data Annotation Services Cost?” pricing guide, accessed November 9, 2026).
- Per annotator hour, managed: about $6 per annotator hour for projects billed by time (Label Your Data, published pricing page, accessed November 9, 2026). This is the only public hourly rate card among the managed vendors we profile.
- Full range: AI data annotation costs run roughly $2 to $300 an hour, driven by task complexity, skill, and required quality (Outsource Accelerator, “What AI data annotation costs: From $2 to $300 an hour,” accessed November 9, 2026). LXT’s 2026 outsourcing guide puts the working range at about $10–$300 per hour, with commodity labeling at the bottom.
- Most vendors: 9 of the 10 companies in our comparison publish no rate card at all — pricing is quote-only. That is itself a finding: budget for a sales process, and convert every quote to a comparable unit before deciding.
What annotators and experts are paid (a different number)
- Bulk labeling: reported annotator pay runs from $2 an hour or less for bulk labeling in Kenya up to $150 an hour or more for software engineers (Second Talent, “Data Annotation Costs by Country,” 2026).
- Expert platforms: DataAnnotation.tech advertises expert rates of $75–$125+ per hour, with coding work up to $150+ per hour (dataannotation.tech, accessed November 9, 2026). Outlier, Scale AI’s expert platform, is reported at around $60 per hour for expert tiers (TIME, April 2024; community pay comparisons, 2026).
- Job postings: US data annotation job listings span $17–$100 per hour (ZipRecruiter listing snapshot, November 2026).
The gap between the two lists is the vendor’s margin: recruiting, training, QA, tooling, and profit. A $6/hour managed rate and a $2/hour annotator wage can describe the same hour of work. Neither number is “the price of annotation” on its own.
Why quotes vary so much
- Skill tier: commodity labeling vs. credentialed experts (medicine, law, finance, PhD-level) is a 10–50× hourly difference.
- Modality: image bounding boxes are cheap; video, 3D/LiDAR, and sensor-fusion work is not.
- QA depth: single-pass labeling vs. consensus + expert review multiplies cost per accepted label.
- Geography and workforce model: where annotators sit, and whether they are employees or contractors, drives both price and compliance exposure.
