How to Calculate Work Experience for Your Resume

When applying for jobs, accurately stating your years of experience is critical. Overstate it, and you lose trust; understate it, and you might not pass the ATS (Applicant Tracking System) filter.

How do you calculate work experience for a resume?

To calculate work experience, subtract your start date from your end date for each job. Calculate the total years and months for each role individually. If you held multiple jobs at the same time (overlapping employment), do not double-count those days. Your total experience is the sum of your unique days worked.

The 3 Rules of Resume Experience Calculation

1. Inclusive Counting: Count both your start month and end month. (e.g., January 2020 to January 2021 is 1 year and 1 month, not exactly 1 year).
2. Merge Overlaps: If you worked two jobs from June 2021 to August 2021, that period only counts once toward your total professional experience.
3. Identify Gaps: Be honest about career gaps. You do not need to list gaps on your resume, but knowing them helps you prepare for interviews.

Should I include part-time jobs in total experience?

Yes, if the part-time job is relevant to the role you are applying for. However, you may choose to pro-rate the experience. For example, 2 years of part-time work (20 hours/week) could be listed as "1 year equivalent full-time experience."

How do overlapping jobs affect my resume?

Overlapping jobs are common (e.g., consulting, transitioning between roles). When listing them on your resume, keep the dates clear. When calculating your total years of experience for a summary statement, merge the overlapping months so you don't misrepresent your tenure.
