A pipeline degree — the real money starts at graduate school
Biology graduates earn a respectable $82,087 at the 10-year mark per Census PSEO, but the undergraduate entry is rough: bachelor's year-1 earnings are just $32,252, producing a debt-to-income ratio of 0.628 against the $20,240 institution-level median debt — well outside the 0.40 healthy threshold. BLS projects only +0.85% weighted employment growth for biology-linked occupations over 2024–2034, roughly one-fifth of the +4.0% all-occupations baseline. The largest single destination — secondary school biology teachers — is actually shrinking (-1.6%). The six-figure seats (medical scientists at $100,590 median, +8.7% growth; natural sciences managers at $161,180) all require a doctoral or professional degree. The typical path is a bachelor's in biology followed by medical school, a PhD program, or a lateral pivot. If graduate school isn't on the table, the undergraduate degree alone rarely delivers on its reputation.

Biology sits on a reputation gap. The field carries real cultural weight — pre-med, pre-dental, the research-scientist archetype — but the undergraduate numbers tell a story most advisors don't lead with. A bachelor's graduate earns $32,252 in year 1 per College Scorecard, putting the debt-to-income ratio at 0.628 against the $20,240 institution-level median debt. That's well past the 0.40 healthy threshold. The 10-year Census PSEO median climbs to $82,087, but that figure is propped up by graduates who pursued medical school, dental school, PhDs, or pivoted out of the field altogether.
The labor-market backdrop is also softer than the field's reputation suggests. BLS projects weighted employment growth of just +0.85% across biology-linked occupations for 2024–2034 — roughly one-fifth of the +4.0% all-occupations baseline. The single largest destination, secondary school biology teachers, is projected to shrink by 1.6% over the same period. The high-wage destinations — medical scientists at $100,590 median, postsecondary biology teachers at $83,460, natural sciences managers at $161,180 — all require a doctoral or professional degree.
The rest of this page walks through earnings by credential, debt load, and where biology graduates actually work — so a student deciding between biology and, say, nursing or engineering can see what the bachelor's alone is worth and what it takes to unlock the upside.
- ✓ Census PSEO shows median earnings of $82,087 at year 10, with the 75th percentile reaching $122,802.
- ✓ Doctoral graduates earn $76,854 at year 1 — debt-to-income ratio of 0.263, the only healthy credential tier.
- ✓ Three-year loan default rate across 1,781 biology-producing institutions is 0.002% — effectively zero repayment distress.
- ✓ BLS projects ~113k annual job openings across biology-linked occupations through 2034 — the market is deep even if growth is slow.
- ! Weighted employment growth is just +0.85% over 2024–2034 — roughly one-fifth of the +4.0% all-occupations baseline.
- ! Secondary school teachers (the single largest destination at 1.09M employed) is projected to shrink -1.6% through 2034 per BLS.
- ! Bachelor's debt-to-income ratio is 0.628 — debt $20,240 vs. year-1 earnings of just $32,252 — well past the 0.40 healthy threshold.
- ! Medical scientists ($100,590, +8.7%) and postsecondary biology teachers ($83,460, +7.3%) both require a doctoral or professional degree.
- ! College Scorecard field-level debt is null across all credential tiers; the $20,240 figure is an institution-level fallback.

Earnings by credential level
College Scorecard field-level earnings (years 1–4 post-grad, aggregated across institutions)
What it costs, what you earn, what's left over
College Scorecard does not publish field-level debt for biology at any credential tier — the fieldLevelSparse flag is true across all eight credential categories. The debt figure here, $20,240, is the institution-level median across the 1,781 schools producing biology credentials. That's a blunt instrument: it doesn't separate a two-year associate's at a community college from a four-year bachelor's at a private university, and it almost certainly understates borrowing at the master's and doctoral tiers. Anyone pricing a specific program should check net price data directly rather than lean on this aggregate.
Applying that single figure across tiers, the debt-to-income picture is only healthy at the doctoral level. Associate's graduates earn $29,145 in year 1 — a debt-to-income ratio of 0.694, meaningfully outside the 0.40 healthy threshold. Bachelor's graduates earn $32,252 in year 1, producing a ratio of 0.628 — still unhealthy. The master's tier lands at 0.451 — improved, but still past the threshold. Only the doctoral tier, with year-1 earnings of $76,854, delivers a healthy 0.263 ratio. This isn't a debt-heavy field — the $20,240 figure sits near the national median — but early-career earnings for biology graduates are low enough that the ratio fails at every tier below the PhD.
One bright spot in the data: the three-year loan default rate across biology-producing institutions is 0.002% — effectively zero. That's an order of magnitude below the ~7% national average for two-year institutions and ~3% for four-year institutions. Graduates may be underpaid relative to debt in their first years, but they're not defaulting. Interpretation: biology students come from backgrounds, and go into second-chapter credentials, that support repayment — but the undergraduate-alone path is financially stressed in a way the default rate hides.
The credential paths that actually produce graduates
Scorecard field-level earnings + completions_by_program (most recent year) aggregated by credential tier
Associate's in Biology
A two-year program covering general biology, introductory chemistry, and lab technique — typically a transfer credential rather than a terminal degree. Leads to biological or agricultural technician roles, or (more commonly) articulates into a four-year program.
- Completions / yr 7,980
- Year-1 earnings $29,145
- Year-4 earnings $44,447
- Median debt $11,524
- % women 70.5%
- Schools 408
Best for students planning to transfer to a bachelor's program or entering entry-level lab-technician work — not a destination credential on its own.
Bachelor's in Biology (BS/BA)
The standard four-year path covering molecular and cell biology, genetics, ecology, physiology, and organic chemistry — along with labs and often a capstone research experience. The bulk of biology graduates (81,600 of 100,135 total completions in 2024) hold this credential. Year-1 median earnings are $32,252, rising to $58,010 by year four per College Scorecard.
- Completions / yr 81,600
- Year-1 earnings $32,252
- Year-4 earnings $58,010
- Median debt $22,735
- % women 68.4%
- Schools 1,389
The right choice for students aiming at medical school, PhD programs, or health-professional school — the undergraduate prerequisite for essentially every upper-path destination.
Master's in Biology
A one-to-two-year graduate program specializing in fields like microbiology, ecology, biotechnology, or bioinformatics — often with a thesis or applied-research component. Year-1 median earnings climb to $44,913, reaching $76,806 by year four per College Scorecard. The 0.45 debt-to-income ratio at this tier is still above the 0.40 healthy threshold.
- Completions / yr 7,759
- Year-1 earnings $44,913
- Year-4 earnings $76,806
- Median debt $42,435
- % women 66.6%
- Schools 470
Practical for students targeting industry research roles, lab-management positions, or a PhD on-ramp — less useful as a purely financial upgrade over a bachelor's.
Doctoral (PhD) in Biology
A five-to-seven-year research degree producing independent scientists. Year-1 median earnings are $76,854, rising to $122,666 by year four per College Scorecard — the only tier where the $20,240 institution-level debt figure produces a healthy 0.263 debt-to-income ratio. Opens tenure-track academia, industry R&D, and medical-scientist roles.
- Completions / yr 1,890
- Year-1 earnings $76,854
- Year-4 earnings $122,666
- Median debt $20,240
- % women 57.7%
- Schools 204
For students who want to run their own research program — either in academia or industry — and are willing to accept the long training window.
The bachelor's is the obligatory entry ticket, not a destination. The real earnings gap opens at the doctoral level — and that's the only tier where the debt math actually works cleanly.
Biology produces credentials at serious scale — 100,135 completions in 2024 across all tiers — but the distribution is heavily bottom-heavy. Bachelor's degrees account for 81,600 completions (81%), followed by associate's at 7,980, master's at 7,759, and doctoral at just 1,890. Certificates and post-bac credentials add another ~900 combined. Nearly 90% of biology graduates hold a bachelor's or associate's degree — and the earnings data for those two tiers is the softest in the dataset.
The earnings gap between the associate's and bachelor's is real but narrow at the starting line. Associate graduates earn $29,145 at year 1 and $44,447 by year four. Bachelor's graduates start at $32,252 and reach $58,010 — a $13,563 gap at the four-year mark. That's meaningful, but nothing like the credential cliff the field implies. The real earnings jump happens at the doctoral level: year-1 earnings leap to $76,854 (a $44,602 premium over the bachelor's) and $122,666 by year four. The master's tier sits in between — $44,913 year 1, $76,806 by year four — a modest premium over the bachelor's but not the earnings transformation the doctoral degree delivers.
One demographic note: biology is 68.2% women across all tiers in 2024, with the share peaking at the associate's level (70.5%) and dropping through the credential ladder to 57.7% at the doctoral tier. That doctoral-level drop mirrors patterns across the natural sciences but is less severe than in physics or engineering. The completion trend is slightly down — 102,340 graduates in 2023 fell to 100,135 in 2024 — suggesting a marginal cooling of interest, not a collapse. Field-level debt data is missing across every tier, so all debt figures here lean on the $20,240 institution-level fallback.

The destination map for biology graduates is wider than most majors and that's part of the problem — the weighted picture averages across occupations that don't share a career ceiling. Secondary school teachers (SOC 25-2031) dominate raw employment at 1.09M workers, with a median wage of $64,580 and a projected -1.6% growth through 2034 per BLS. That single shrinking occupation accounts for roughly 60% of the ~113k annual openings the field generates — most of them replacement demand, not net new jobs. The typical education requirement is a bachelor's, which aligns with the dominant biology credential.
The high-wage destinations tell a different story but require different credentials. Medical scientists (SOC 19-1042) earn $100,590 median with +8.7% projected growth — but the typical requirement is a doctoral or professional degree, and only 165,300 positions exist nationally. Postsecondary biology teachers (SOC 25-1042) earn $83,460 with +7.3% growth, also requiring a doctorate. Natural sciences managers (SOC 11-9121) top the wage chart at $161,180 median, with +3.7% growth and a bachelor's-level educational floor — but that role is a mid-career destination, not an entry point, and only ~8,500 openings appear annually.
The bachelor's-level entry titles are where the wage story sours. Biological technicians (SOC 19-4021) earn $52,000 median with +3.5% growth and ~9,100 annual openings. Food science technicians ($49,430) and agricultural technicians ($46,790) sit in a similar band. The one bright outlier at the bachelor's level: forensic science technicians (SOC 19-4092) project +12.8% growth — the highest in the dataset — but the occupation is small (20,700 employed, ~2,900 openings per year). The pattern is consistent: biology's growth stories are in small occupations or in roles that require a doctorate, while its largest employment destination is shrinking.

Biology is worth it under two conditions. First: a concrete graduate or professional-school plan. The doctoral path delivers $76,854 at year 1 — the only credential tier where the $20,240 institution-level debt produces a healthy 0.263 debt-to-income ratio — and opens the high-wage occupations (medical scientists at $100,590, postsecondary biology teachers at $83,460, natural sciences managers at $161,180) that the bachelor's alone doesn't reach. Pre-med and pre-dental students use biology as a prerequisite pipeline, which works fine as long as medical school is the actual destination. The bachelor's is a ticket to the next stage, not an earnings credential on its own.
Second: genuine intellectual commitment to the subject. The numbers at the bachelor's level are hard to defend purely financially — $32,252 in year-1 earnings, a 0.628 debt-to-income ratio, and +0.85% weighted employment growth against a +4.0% all-occupations baseline. A student picking biology as a generic STEM default, or because it sounds more credentialed than the humanities, is choosing one of the weaker undergraduate ROI profiles in the natural sciences. Nursing, engineering, computer science, and even accounting deliver meaningfully better bachelor's-level earnings for similar debt loads.
If graduate school is off the table and the student is comfortable with teaching or lab-technician work at a $50k–$65k wage band, the degree still functions — but the family-funded cost calculus changes. An in-state public university with research opportunities, low net price, and a strong pre-health or pre-grad pipeline is the smartest version of this path. Private-university sticker price for a biology bachelor's with no grad-school plan is the hardest case to make in this dataset.
Informed inquiries
Is a biology degree worth it if I don't want to go to medical school or get a PhD?
The honest answer is: not on the numbers alone. Bachelor's-level biology graduates earn $32,252 at year 1 per College Scorecard — below nearly every other STEM field. The $82,087 median at year 10 from Census PSEO is decent, but that figure is diluted by graduates who pursued medical school, dental school, PhDs, or pivoted into finance or consulting. The bachelor's-only path typically lands graduates in biological-technician roles ($52,000 median) or secondary school teaching ($64,580 median), the latter projected to shrink -1.6% through 2034. If graduate or professional school genuinely isn't the plan, a biology bachelor's is a weak financial bet compared to nursing, engineering, or computer science at the same undergraduate level.
Why is the debt-to-income ratio so bad for biology at the bachelor's level?
Because year-1 earnings are unusually low. The institution-level median debt of $20,240 isn't high by national standards — it's in line with most humanities degrees — but bachelor's graduates earn only $32,252 in their first year, producing a 0.628 debt-to-income ratio, well outside the 0.40 healthy threshold. College Scorecard's field-level debt data is null for biology across every credential tier, so the $20,240 figure is an institution-level fallback across 1,781 schools. The ratio only becomes healthy at the doctoral tier (0.263), where year-1 earnings reach $76,854. This isn't a debt problem — it's an entry-wage problem, tied to biology being a pipeline degree rather than a terminal one.
What jobs do biology graduates actually get right out of college?
The largest destinations are secondary school biology teachers (SOC 25-2031, 1.09M employed, $64,580 median wage, projected -1.6% through 2034), biological technicians (SOC 19-4021, $52,000 median, +3.5% growth), and a long tail of technician roles in food science, agriculture, and forensic science — most paying $46,000–$67,000. Bachelor's-only graduates rarely land the high-wage titles the field advertises: medical scientists ($100,590) require a doctoral degree, natural sciences managers ($161,180) require both a bachelor's and years of experience, and biological scientists ($93,330) typically need a PhD or master's. The realistic bachelor's-out-of-college wage floor is ~$32,000–$52,000, not the $75,325 weighted average across all experience levels.
If the upside is in grad school, does it matter which biology program I pick?
Yes — more than for most majors. Research opportunities, faculty mentorship, and MCAT/GRE preparation pipelines differ sharply between programs. The volume leaders — University of South Florida (1,091 completions), Florida International (1,023), Texas A&M (1,011), Arizona State (896), UCF (886) — produce large biology cohorts and have established pre-med and research tracks. Johns Hopkins (632) and UT Austin (744) send stronger flows into medical school and PhD programs. Community colleges like Houston Community College (626 completions) are transfer-oriented associate's programs, not terminal destinations. For students planning grad school, the right metrics are research participation rates, medical school acceptance rates, and PhD placement — none of which are in this data packet, but all of which should drive the choice more than undergraduate ranking.
Is a master's in biology a good step, or should I skip to a PhD?
It depends on the goal. Year-1 earnings at the master's level are $44,913 — a $12,661 premium over the bachelor's $32,252 — rising to $76,806 by year four per College Scorecard. The debt-to-income ratio improves to 0.451, though that's still above the 0.40 healthy threshold. For students aiming at industry research, biotechnology, or lab-management roles, the master's is a legitimate destination: 7,759 graduates earned one in 2024. But for an academic research career, most programs fund PhDs directly and view terminal master's candidates with some skepticism. If a PhD is the end goal, apply to PhD programs — a funded PhD means no added debt, which the master's tier cannot match.
How does biology compare to nursing or engineering for pure ROI?
Biology loses on the numbers at the bachelor's level. Nursing bachelor's graduates earn $75,348 at year 1 with a 0.23 debt-to-income ratio; biology bachelor's graduates earn $32,252 with a 0.628 ratio. The 10-year gap narrows — biology's $82,087 PSEO median is genuinely strong — but that's partly because the long-term cohort is heavy with medical, dental, and PhD graduates whose earnings reflect additional degrees, not the bachelor's alone. Against engineering, biology's weighted occupational growth of +0.85% is far below engineering-adjacent occupations, which typically exceed the +4.0% baseline. The defensible case for biology is love of the subject plus a concrete grad-school or professional-school plan — not ROI head-to-head.
