How the ATS Score Is Calculated

A transparent breakdown of the nine factors and their weights

Your ATS score is a weighted average of nine factors, scored from 0 to 100. We publish the weighting below so you know exactly what drives your score and where to focus. Keyword and skills matching together account for half your score — because that's what real applicant tracking systems weight most heavily.

Scoring Weights

FactorWeightWhat it measures
Job-description keyword match30%How many skills, tools, and terms from the specific job posting appear in your resume.
Skills match20%Alignment of your hard and soft skills with the role's requirements.
Resume parsing / readability15%Whether the ATS can cleanly extract your text. Image-based PDFs fail here.
Section headings10%Use of standard, recognizable headers (Experience, Education, Skills).
Job-title alignment10%Whether your titles map to the role you're targeting.
Formatting (columns / tables)10%Single-column, parser-safe layout vs. multi-column or table-based designs.
File type & date formatting5%ATS-compatible file format and consistent, parseable dates.

Weights are approximate and may be refined as ATS platforms evolve. The exact internal logic is proprietary, but these weights reflect how the score is composed.

Why Resumes Gain or Lose Points — Examples

− Lost points: keyword match

The posting asks for "stakeholder management" and "Agile delivery." The resume says "worked with teams" and "managed projects." The meaning is similar, but the exact terms are missing — so the keyword-match factor (30%) drops significantly.

− Lost points: formatting

A two-column template places skills in a sidebar. The parser reads left-to-right across both columns, scrambling the content. The formatting factor (10%) and parsing factor (15%) both take a hit.

+ Gained points: section headings + skills

Switching "My Journey" to "Professional Experience" and adding a clear "Skills" section with the posting's exact tools lets the parser categorize everything correctly — lifting the headings (10%) and skills (20%) factors.

+ Gained points: parsing

Replacing an image-based PDF (scanned) with a text-based .docx means the ATS can actually read the content. Parsing/readability (15%) jumps from near-zero to full credit.

How to Use the Weighting

Because keyword match (30%) and skills match (20%) are half your score, the single highest-impact action is tailoring your resume's keywords to each specific job posting. After that, fixing parsing and formatting issues (25% combined) protects the score you've earned. Standard headings, aligned titles, and clean file formatting handle the rest.

Frequently Asked Questions

How is the ATS score calculated?
A weighted average of nine factors. Keyword match is 30%, skills match 20%, parsing 15%, then headings, title alignment, and formatting at 10% each, with file type and dates at 5%. Range is 0–100.
Which factor affects my score the most?
Job-description keyword match at 30%. Combined with skills match (20%), keyword and skill alignment make up half your score.
Why did my resume lose points?
Usually missing keywords, multi-column/table layouts, non-standard headings, misaligned job titles, image-based PDFs, or inconsistent dates — each maps to one of the nine factors.
Is the exact algorithm public?
The factor weights are public so you know what to improve. The precise internal logic is proprietary, but the weighting gives you enough to act on.
