College Major Earnings Comparison Calculator

How college-major salary paths are compared

Choosing a college major is never only about money, but earnings are often one part of the decision. Students may be weighing subject interest, job availability, flexibility after graduation, and the ability to support themselves over time. This college-major earnings calculator focuses on one limited part of that choice: a modeled salary path. It cannot tell you what you should study; it helps put one financial tradeoff into numbers so it can be considered alongside the rest of the decision.

A major's salary outlook is more than one entry-level-pay figure. A path with a high first-year salary may remain ahead for decades, while a path that begins lower can sometimes narrow the gap through faster raises and promotions. That is why the comparison uses both starting salary and annual growth. Career length matters too, because salary growth has more time to compound over a longer working horizon. A ten-year comparison can point in a different direction from a thirty-five-year comparison.

For college-major comparisons, the most useful approach is to treat the output as a scenario rather than a prediction. Try cautious, baseline, and stronger-growth assumptions. You can examine a shorter period before graduate school, a career with slower advancement, or a path where one major starts higher while another has steadier salary progression. Testing those assumptions is generally more informative than relying on a single lifetime-total estimate.

College-major earnings inputs explained

Starting salary ($) is the annual pay expected near the beginning of a full-time career related to that major. For many comparisons, that means first-year pay after graduation in a typical entry-level role. When using salary surveys, use figures from comparable sources and locations where possible. A salary from a high-cost city is not directly comparable with a national figure unless location is accounted for elsewhere.

Annual growth rate (%) estimates how pay associated with that major changes each year. In this model, the rate combines ordinary raises, promotions, moves into better-paying specialties, and career progression. A major with a lower entry salary but better long-run advancement can be represented with a higher rate. Enter the figure as a percentage: 3.5 means 3.5% per year, not 0.035. The calculator converts the entered percentage before calculating totals.

Career length (years) is the number of working years included in the major comparison. It is neither your age nor necessarily a formal retirement date. It is simply the span over which annual earnings are added. Someone considering a career from age 22 through age 57 might model 35 years, while someone planning for graduate school or a shorter decision horizon might examine 10 or 15 years.

Every input is annual. Starting salary is annual dollars, the growth rate is annual percentage growth, and career length is a count of years. Consistent units are essential for a meaningful comparison. For example, mixing a monthly pay estimate for one major with annual pay for the other would make the displayed totals misleading.

It is also important to recognize what the major earnings model leaves out. It does not know whether one degree requires graduate school, whether you will change industries, whether you will work part time, or whether one path creates substantially more debt. Those considerations may be decisive. This calculator isolates salary growth so that portion of the comparison is easier to inspect before adding broader personal and financial factors.

How career earnings are calculated for each major

For each college major, the calculator begins with the entered first-year salary and increases that salary by the same percentage every year. The resulting earnings path is a compounding sequence. This makes the assumptions visible: the starting salary establishes the initial level, while the growth rate determines how quickly later annual salaries rise.

If a major begins with salary S, grows at annual decimal rate g, and is modeled for n years, total nominal career earnings T are the sum of the salary in every modeled year:

For a positive growth rate, the calculator uses the equivalent geometric-series expression below. If growth is zero, it uses starting salary multiplied by career length:

The key implication for a major comparison is that a higher growth rate becomes more influential as the career horizon lengthens. When starting salaries are fairly close, a faster-growing path can eventually overtake the other path. Conversely, a large starting-pay advantage can remain important even if the other major has a higher annual growth assumption. Adjusting the years field helps show how those forces interact.

Default college-major earnings comparison example

With the default inputs, Major 1 starts at $65,000 and grows at 3.5% per year, while Major 2 starts at $48,000 and grows at 4.2% per year. Across a 35-year career, the calculator estimates about $4.34 million in nominal earnings for Major 1 and about $3.68 million for Major 2. Under these assumptions, Major 1 remains ahead because its initial salary advantage is large enough that Major 2's faster annual growth does not close the gap within the selected horizon.

This example shows why a growth rate should not be read in isolation. A higher annual rate can be powerful, but it compounds from the salary level at which the career begins. A lower starting salary that grows faster does not automatically produce the higher total. The salary gap, the growth-rate gap, and the number of working years must all be considered together.

The same two majors can also be reviewed over different time horizons. During the early career years, starting salary has an especially large effect on the total. As the horizon extends, the faster growth rate for Major 2 narrows the difference. At 35 years in the default comparison, however, Major 1's higher initial pay still produces the larger modeled total.

When testing your own major assumptions, change one field at a time. First keep the career length fixed and vary the growth rates. Then hold growth steady while shortening or extending the working horizon. That approach makes it clearer which assumption is changing the comparison.

Reading a college-major earnings result carefully

The main result reports modeled nominal career earnings for each major over the working years selected. The summary table also shows average annual salary, calculated as total modeled earnings divided by career length. That average can make the long-run totals easier to relate to the annual salary path behind them.

If one major leads by a large amount, the financial difference is worth examining. If totals are close, money alone may not be a useful tie-breaker. In close comparisons, subject fit, likelihood of completing the degree, graduate-school plans, work-life preferences, debt, and job opportunities can outweigh the difference displayed on the screen. A small percentage gap is often better interpreted as broadly similar pay potential than as a definitive winner.

The scenario table below the result tests the entered major assumptions by shifting both annual growth rates down one percentage point, leaving them unchanged, and shifting them up one percentage point. It is not a forecast. It is a way to see whether the comparison changes materially when salary-growth expectations are less favorable or stronger than the baseline you entered.

Limits of a college-major earnings projection

This college-major calculator deliberately uses a straightforward salary model so the comparison remains understandable. That simplicity is useful, but the result is a structured estimate rather than a promise about an actual career. Industries, cities, economic conditions, graduate programs, and individual choices can all alter salary paths substantially.

• Constant growth: each major uses one steady annual salary-growth rate. Actual careers can include uneven raises, promotions, plateaus, and setbacks.
• Nominal dollars: the calculator does not adjust for inflation, so its totals represent nominal future earnings rather than purchasing power.
• No taxes or education costs: taxes, tuition, student-loan payments, and graduate-school costs are not included, even though they can substantially affect financial outcomes.
• No employment gaps: the calculation assumes earnings continue throughout the selected years. Career breaks, unemployment, internships, and part-time work are not modeled.
• No regional adjustment: salary figures from different cities may not be comparable after housing and other living costs are considered.

Use the major comparison alongside personal judgment. A major that produces somewhat lower modeled earnings may still be a better choice if it fits your strengths, interests, and likelihood of graduating. Likewise, if two majors are equally appealing and one holds a financial advantage across several growth assumptions, that is relevant evidence rather than a final answer.

In practice, this tool is most useful for asking what conditions would allow one major's salary path to pull ahead. Run several plausible cases, watch how the result changes with the career horizon and growth rates, and treat the totals as one input in a broader education and career decision.
