Average Marine Biologist Salary in Puerto Rico for 2026

How much does a marine biologist make in Puerto Rico?

A typical marine biologist working in Puerto Rico brings home around 2,558 USD a month before tax. Entry-level pay starts near 12,000 USD, and the top of the ladder reaches roughly 49,000 USD for the most experienced and specialised people in the role.

The wide gap between low end and top end reflects how much pay can vary inside the same job title. A junior marine biologist working at a small local employer earns very different money from a senior at a multinational. Skills, employer, city and years in the seat all push the number around. For a cross-country comparison, see the marine biologist salary in United States or Palau, both of which pay in the same currency.

How marine biologist pay ranges in Puerto Rico

A good way to think about salary in Puerto Rico is to look at the distribution rather than the headline average. Half of all marine biologists in Puerto Rico earn less than 30,700 USD a year, and the other half earn more. That middle number is the median, and it is usually more useful than the average for answering "is my pay normal here".

Looking at the quartiles fills in the picture. A quarter of earners take home less than 20,200 USD (the 25th percentile), and a quarter clear 44,800 USD (the 75th percentile). The middle 50% of marine biologists sit somewhere inside that band, which is where the typical reader of this page probably lives.

The very lowest reported salaries sit around 12,000 USD. The highest stretch to 49,000 USD, though only a small fraction of earners ever reach that level. If you are deciding whether your own offer or current pay is reasonable, work out which of those four bands you would fall into and use that as your reference point.

Marine biologist pay by experience in Puerto Rico

Years of experience is the single biggest lever on pay for a marine biologist in Puerto Rico, ahead of education and almost any other single factor. The longer you have been in the role, the more your employer can trust you to handle complexity, mentor others and act independently, all of which command higher pay. The chart below shows how the typical marine biologist salary changes as you move through the career ladder.

The single largest jump on the ladder is from 2 - 5 Years to 5 - 10 Years, where pay rises by about 40%. That is the point at which a marine biologist typically goes from "competent in the role" to "the person other people in the team learn from", and the market pays well for that step.

Marine biologist pay by education in Puerto Rico

Education sits alongside experience as one of the biggest factors driving marine biologist pay in Puerto Rico. Higher qualifications consistently pull higher salaries, but the size of the gap tends to be smallest at junior levels and widens as people move up. Two people in the same role with the same years of experience but different degrees can end up earning very different money once they reach mid-career.

Marine biologist gender pay gap in Puerto Rico

The gender pay gap is a stubborn feature of almost every labour market, and Puerto Rico is no exception. Male marine biologists in Puerto Rico earn an average of 32,900 USD a year, while female marine biologists earn around 28,800 USD. That works out to a 14% gap in favour of men, even when comparing people doing the same work.

A pay gap of this size has a real long-term cost. Over a typical thirty-year career it can add up to several years of pay, and it compounds through pensions, retirement contributions and bonus-linked stock. Some of the gap is explained by women being more likely to work part-time, take career breaks, or be steered toward lower-paying specialisations. Some of it is straightforward unequal pay for the same job, which is harder to defend.

Pay raises for a marine biologist in Puerto Rico

Most countries hand out at least some kind of pay raise every year, typically when an employee's contract is reviewed or as a cost-of-living adjustment to keep wages roughly in step with inflation. The rhythm and size of those raises varies hugely between industries.

A typical worker doing this role in Puerto Rico sees a raise of about 8% every 29 months, which works out to roughly 3% on an annual basis. That figure is the typical underlying rate; in years where inflation runs high you can usually expect a bit more, and in flat-economy years a bit less.

Across all jobs in Puerto Rico, the national average raise is around 4% every 29 months.
