Median first-year pay for Data Scientists runs close to $120,042 nationally. Here is how people get there, and how long it takes.


TL;DR

  • National median for Data Scientists: $120,042 (BLS OES, May 2025).
  • Most people enter through a bachelor's degree in a quantitative field. A small but growing share comes through bootcamps plus a graduate certificate.
  • Timeline from "I want to do this" to first paycheck: 18 to 48 months, depending on your starting point.
  • The occupation is projected to grow 33.5% by 2034. That is not a rounding error.

The Number (with Source)

Data Scientists earned a national median annual wage of $120,042 in May 2025 (BLS OES, SOC 15-2051, retrieved 2026).

The mean sits higher, at $126,321, which tells you the distribution is right-skewed. Senior specialists and quant-heavy roles in finance or tech pull the average up.

Employment total as of May 2025: 262,410 people held this title in the US.

Median is $120,042. From here we shorten to $120k for readability.


What the Number Does Not Say

BLS OES reports the median across all experience levels and all industries. A first-year Data Scientist at a regional insurer is not earning what a third-year Data Scientist at a San Francisco AI firm earns. Both sit inside that $120k figure.

BLS also suppresses small cells when employment in a given state or metro falls below a reporting threshold. If your state-level median shows "n/a" on the BLS state OES page, that is a suppression, not an absence of jobs.

The national median is a floor check, not a job offer.


The Decision Frame: Training, Timelines, and First-Year Pay

This is the structural question most career-changers search with. We break it into three tracks, because the answer genuinely depends on where you are starting.

Track 1: Traditional Degree Path

Most practicing Data Scientists entered through a four-year quantitative degree. O*NET classifies the typical entry requirement as a bachelor's degree with no prior experience required (O*NET 15-2051.00).

Common majors:

  • Statistics or applied mathematics
  • Computer science with a data-systems focus
  • Economics with a heavy econometrics load
  • Information science or data science (newer but growing)

Timeline: 4 years from enrollment to first role, assuming a direct path.

First-year pay for this track tends to land in the $85k–$105k range at mid-market employers, based on the distribution implied by BLS OES percentile data. The median of $120k reflects the full workforce, not just entrants.

Track 2: Graduate Degree After an Unrelated Bachelor's

A sizable portion of the workforce pivoted from a non-quantitative field and returned to school for an MS in Data Science, Statistics, or Applied Mathematics.

Timeline: 2 to 3 years (1.5–2 years of grad school plus a 3–6 month job search).

The advantage here is salary. Candidates entering with an MS from a known program often start closer to the median. The cost is real: tuition for a reputable MS ranges from $25,000 to $80,000 total.

Track 3: Bootcamp Plus Credential

A smaller but measurable segment enters through a 12–24 week intensive bootcamp followed by self-directed study for technical interviews.

Timeline: 12 to 18 months to first job, for a disciplined candidate with a strong portfolio.

The risk is real. Bootcamp graduates compete against candidates with stronger theoretical depth. First-year pay for this track is harder to peg because reporting is thin and bootcamp outcome surveys are self-selected.

The honest frame: bootcamps work as entry vectors when the candidate already holds a numerically literate degree (engineering, finance, biology with statistics) and is adding Python, SQL, and modeling skills on top.


Side-by-Side: Three Tracks Compared

TrackTypical DurationEstimated Entry PayCredential Cost
Bachelor's (direct)4 years$85k–$105k$40k–$120k tuition
MS after bachelor's2–3 additional years$100k–$120k$25k–$80k
Bootcamp + portfolio12–18 months$70k–$95k$10k–$20k

Entry pay figures are directional, not BLS-certified. BLS does not break out entry-level from the full median. We derived the ranges from the shape of the OES percentile distribution.


What Skills Actually Get You Hired

O*NET lists the core knowledge areas for SOC 15-2051 (O*NET summary):

  • Mathematics (statistics, linear algebra, probability)
  • Computers and electronics (Python, SQL, cloud tools)
  • English language (written and oral communication — hiring managers cite this more than candidates expect)
  • Administration and management (project scoping, stakeholder translation)

Three skills that consistently separate candidates who land offers from those who do not:

  1. SQL fluency at the window-function level, not just SELECT basics.
  2. A public portfolio with at least two end-to-end projects: raw data in, business answer out, with documented methodology.
  3. The ability to explain a model to a non-technical stakeholder in under three minutes.

The Growth Story

The BLS projects Data Scientist employment to grow 33.5% from 2024 to 2034, compared to the 4% average for all occupations (BLS Employment Projections).

Employment is projected to rise from 246,000 to 328,000 positions in that ten-year window. That is roughly 82,000 net new jobs, not counting replacements for attrition.

The occupation carries a "Bright Outlook" designation from O*NET. That flag is not marketing. O*NET applies it mechanically when BLS projects growth above 20% or absolute new openings exceed specific thresholds.

The job market is expanding faster than the pipeline of trained candidates, which puts negotiating leverage on the candidate side.


Building a Realistic Timeline

Here is how to map your personal path against the data:

If you are currently in a quantitative bachelor's program:

  • You are 0–3 years out from a competitive entry-level application.
  • Use the time to build a portfolio before graduation. Employers treat a GitHub with two well-documented projects as equivalent to a full semester of coursework for hiring purposes.
  • Target internships in data analyst or BI roles before applying to Data Scientist titles.

If you hold a non-quantitative bachelor's and are considering a pivot:

  • An MS is the highest-probability path to a first-year salary near the $120k median.
  • A self-taught route is viable but extends the timeline by 6–12 months and requires stronger portfolio evidence.
  • Read RateOrchard's full guide to becoming a Data Scientist before committing to a program.

If you are already working in a data-adjacent role (analyst, BI developer, statistician):

  • Your timeline is shorter than it looks. The technical gap may be 6–12 months of targeted skill-building.
  • Your negotiating position on first-year pay is stronger because you bring domain knowledge.
  • Check the Data Scientist salary page filtered to your state before you ask for a title change at your current employer. The number matters in that conversation.

FAQ

What degree do most Data Scientists hold?

O*NET classifies the typical entry-level education for Data Scientists (SOC 15-2051) as a bachelor's degree. In practice, a large share of the workforce holds a graduate degree, particularly in roles at technology companies, financial institutions, and research organizations. A bachelor's in statistics, computer science, or a related quantitative field is the minimum competitive credential for most job postings. Graduate degrees raise starting salaries and open roles with higher modeling complexity.


How long does it take to become a Data Scientist?

The range is 18 to 48 months depending on your starting point. A candidate completing a four-year quantitative degree reaches entry-level competition at graduation. A career-changer completing a 12-month MS program plus a 6-month job search arrives in 18 months from enrollment. A bootcamp-plus-self-study route typically takes 12–18 months for a disciplined candidate who already holds a numerically literate degree.


What is the starting salary for a Data Scientist in 2025?

BLS does not publish a separate entry-level figure. The national median across all experience levels is $120,042 (May 2025). Entry-level salaries at mid-market employers typically fall in the $85k–$105k range based on the percentile distribution. First-year pay at large technology or financial services firms can exceed $120k when total compensation includes equity or bonuses, but base salary for new graduates rarely starts at median.


Is a data science bootcamp worth it?

It depends on your existing background. Bootcamps work best as a skill-layer for candidates who already hold a quantitative degree and need to add Python, SQL, and machine learning techniques. For candidates without a mathematical foundation, a bootcamp is unlikely to produce a competitive portfolio in the time most programs run. The credential itself carries less weight than what you can demonstrate in an interview. Employers test for skill, not for the name of the program.


How fast is the Data Scientist job market growing?

BLS projects 33.5% employment growth for Data Scientists from 2024 to 2034. That compares to a 4% projected growth rate for all occupations in the same period. In absolute terms, the projection adds roughly 82,000 net new positions. The O*NET Bright Outlook designation reflects this same underlying BLS projection. The growth is driven by increased demand for predictive modeling in healthcare, finance, retail, and technology sectors.


Do Data Scientists need a PhD?

Most do not. O*NET and BLS classify the typical entry requirement as a bachelor's degree. PhD holders fill a specific subset of roles, primarily in research-intensive environments: academic labs, pharmaceutical R&D, and some AI research teams at large technology companies. For the majority of industry Data Scientist roles, an MS or a strong bachelor's plus a portfolio is the practical standard. A PhD extends the path by 4–6 years and is only worth it if the target role explicitly requires one.
