How to use
- 01
Enter the trade programme's cost and the number of months it runs, then what you earn during it — an apprenticeship wage, or part-time work — expressed as a yearly figure.
- 02
Enter the four-year degree's cost net of grants and scholarships, the years it takes, and what you would earn while studying. Most students earn something; entering zero overstates the degree's cost.
- 03
Enter the pay each route leads to and a growth rate for each. These two numbers decide the answer, so look them up rather than guessing: the Bureau of Labor Statistics publishes occupational wages, and College Scorecard publishes earnings by field of study.
- 04
Set the years to compare, the share of pay you would put into retirement on either path, and the return you assume on it. The retirement figures show what starting to contribute years earlier is worth.
- 05
Read the year the degree overtakes the trade, the head start the shorter programme buys by graduation day, and the year-by-year table and chart of both running totals.
Formula
Both paths run from year 1, the first day of either programme, so the shorter one's head start is counted rather than assumed away. Trade path: the programme is measured in months, so a programme ending mid-year gives a part year of training income and a part year of wages. For each year, the months overlapping the programme give that fraction of the training income and that share of the programme's cost; the rest of the year earns the post-programme wage, grown at its own rate for each full year already worked. Net = income − cost. Degree path: while in school, the work income you enter, less that year's share of tuition. After it, the starting salary grown at its own rate. Net = income − cost. Overtake year = the first year after the degree finishes in which the degree path's running total reaches the trade path's. The head start = the difference between the two running totals at the end of the degree's final year. Retirement pot on each path = the share of pay you set, contributed from each year's earnings and grown at the return you set for the years remaining in the comparison, summed.
Example
A twelve-month trade programme costs $12,000 and pays $22,000 during it, leading to $52,000 a year growing at 2.5%. A four-year degree costs $80,000 net of aid and pays $6,000 a year while studying, leading to $60,000 growing at 3.25%. Both put 6% of pay into retirement at a 6% return, compared over twenty-five years. Year 1 the trade path clears $10,000 — $22,000 of apprenticeship income less the $12,000 programme cost — against −$14,000 on the degree path, which earns $6,000 and pays $20,000 of tuition. By the end of year 4, when the degree finishes, the trade path is $225,933 ahead. The degree spends the next two decades closing that gap and overtakes in year 25. At that point it has cleared $1,711,605 against $1,692,150, ahead by $19,455 — a margin of about 1% after twenty-five years. Retirement tells the same story from the other side: the trade path reaches $205,043 against $194,139, an edge of $10,904 to the trade. Run the same figures over forty years and the picture changes character rather than degree: the overtake is still year 25, but the degree ends $557,749 ahead on earnings ($3,936,464 against $3,378,715), and the retirement edge flips to the degree by $21,078. The lesson is that the horizon you choose, not just the wages, decides which route looks better.
Definitions
- Head start
- The cumulative amount the shorter programme has banked by the time the longer one finishes. In the worked example, $225,933 — money the degree path must out-earn before it is merely level.
- Overtake year
- The first year in which the degree's running total of net earnings reaches the trade's. It can fall outside the period compared, in which case the page says so rather than inventing one.
- Registered apprenticeship
- A paid training programme combining on-the-job hours with instruction, so earnings begin immediately. Enter the wage during it in the training-income field; this page takes no view on which programmes are worth entering.
- Growth rate
- The yearly percentage by which pay rises on each path. Small differences compound hard over decades, which is why a degree with a slightly steeper growth rate can overtake a trade that started far ahead.
- Retirement pot
- What the share of pay you contribute is worth at the end of the period, at the return you set. Contributions made earlier compound for longer, which is the trade's advantage; larger contributions made later are the degree's.
Good to know
Why both paths start on the same day
The commonest way to get this comparison wrong is to compare two graduates. A trade programme finishing in twelve months and a degree finishing in four years do not produce two people standing at the same starting line, and any comparison that begins when each one finishes has thrown away the shorter route's entire advantage. This page runs both paths from the first day of either programme, which is the only arrangement that counts the difference honestly. The effect is visible immediately. In the worked example, year 1 of the trade path clears $10,000: $22,000 of apprenticeship or work income during the programme, less the $12,000 the programme costs. Year 1 of the degree path clears minus $14,000: $6,000 of work income while studying, less $20,000 of that year's tuition. The degree is $24,000 behind after twelve months, and the running total stays negative for several years. The page shows those negative figures rather than starting the count at graduation, because that deficit is the thing the degree spends two decades repaying. By the end of year 4, when the degree finishes, the trade path is $225,933 ahead. That is the head start, and it is the whole financial case for a shorter programme. It is not a bonus or a windfall — it is money already earned and banked while the other path was paying tuition, and the degree must out-earn the trade by that much before the two are merely level. One mechanical detail matters for programmes that do not last a whole number of years. Because the trade programme is measured in months rather than years, a programme ending mid-year produces a part year of training income and a part year of full wages, with the programme's cost spread across the months it actually runs rather than rounded up to a whole year. A ten-month or eighteen-month programme is therefore modelled as it really behaves, which matters because the length of the programme is precisely what generates the head start being measured.
The overtake year, and how much the horizon decides
Whether a degree beats a trade depends enormously on how long you look, and the worked example is deliberately close so that this is visible. Over twenty-five years the degree overtakes the trade in year 25 and finishes ahead by $19,455, having cleared $1,711,605 against $1,692,150. That is a margin of about one percent after a quarter of a century — statistically indistinguishable from a tie, given that both figures rest on wage assumptions nobody can make precisely. Anyone reading that result as a victory for either route has read too much into it. Extend the same figures to forty years and the character of the answer changes. The overtake year does not move — it is still year 25, because that is when the cumulative lines cross — but the degree ends $557,749 ahead, having cleared $3,936,464 against $3,378,715. The reason is compounding in the growth rates rather than anything about the starting wages: the degree path grows at 3.25% a year and the trade at 2.5%, and a three-quarter-point difference applied to a larger salary pulls the two apart faster with every year that passes. This is the single most important thing to understand about the comparison. Over a short horizon the head start dominates and the shorter programme wins comfortably. Over a long one the growth rate dominates and the steeper path wins. The crossover sits wherever those two forces balance, and small changes to either growth rate move it by years. It follows that the honest way to use this page is to run it two or three times at different horizons and different growth rates rather than to read a single number. If the answer flips between twenty-five and forty years — as the example's does, from a near-tie to a half-million-dollar gap — then the comparison is not really telling you which route is better. It is telling you that the decision rests on assumptions about wage growth decades out, which is a different and more honest conclusion.
What starting to save earlier is actually worth
Earning sooner does more than bank a head start; it also starts the retirement clock earlier, and the page models that explicitly because it is the part people most often assert without checking. Putting 6% of pay into retirement on both paths at a 6% annual return, the example's trade path reaches $205,043 after twenty-five years against $194,139 on the degree path — an edge of $10,904 to the trade. The mechanism is exactly the one compounding is famous for: the trade's contributions begin three years earlier and therefore compound for three more years, and early contributions are the ones with the most time to grow. What is less often said is that this advantage is smaller than the rhetoric suggests, and that it reverses. Run the same figures over forty years and the retirement position flips: the degree path reaches $665,369 against the trade's $644,291, an edge of $21,078 the other way. The degree's contributions start later but are larger every year thereafter, because they are a percentage of a higher and faster-growing salary, and given enough time the larger contributions overtake the earlier ones. Both halves of that are worth carrying away. Over a working life of twenty-five years the earlier start wins; over forty it does not. The practical lesson from this section is not about which route to take at all. It is that the contribution rate and the start date do more work in these numbers than the choice of career does. A trade worker contributing 6% from age twenty and a graduate contributing 6% from age twenty-three end up within a few percent of each other after decades, while either one contributing 3% instead of 6% ends up with roughly half. The gap between the two career paths is small compared with the gap between saving and not saving. Whichever route you take, the decision that moves this number most is how much of the pay you put aside and how early you begin, not which pay it is.
The wages this page cannot supply, and what it leaves out entirely
Every wage and salary on this page is a field you fill in, and the defaults are illustrative rather than researched claims about any trade or any degree. That is deliberate, because neither path has a single wage to assert. Pay in the skilled trades varies by trade, by region, and by whether the work is unionised, and the spread within a single trade across the country is wide. Pay by degree varies enormously by field of study — so much so that the gap between two degrees is routinely larger than the gap between having a degree and entering a trade. A national average for either side would be a number with no referent. There are two good places to replace the defaults with something real. The Bureau of Labor Statistics publishes occupational wage data by occupation and by area, which is the right source for a specific trade in a specific region. College Scorecard, at collegescorecard.ed.gov, publishes median earnings by field of study and by institution, which is the right granularity for a degree: not what graduates earn generally, but what graduates of your programme earn. Ten minutes with both will do more for the quality of the answer than any refinement of the arithmetic. It is equally important to be clear about what this comparison ignores, because it compares money and nothing else. It says nothing about physical wear and how long a body lasts in a demanding trade, which is a real and sometimes decisive cost. It says nothing about job security, about whether either field is hiring where you live, about licensing and continuing-education requirements and what they cost over a career, or about how easily one route leads to another later — a consideration that cuts both ways, since some trades fund further study and some degrees lead nowhere in particular. It also assumes both programmes are completed and both jobs are found, which is an assumption and not a fact. Those belong in the decision. None of them can be calculated here, and a page that produced a single verdict would be lying about its own competence.
Frequently asked questions
Does a four-year degree eventually out-earn a trade?
On this page's example it takes until year 25 to do it, and only just. With a $12,000 twelve-month trade programme paying $22,000 during it and $52,000 after, against an $80,000 four-year degree paying $6,000 while studying and $60,000 after, the degree overtakes the trade in year 25 — at which point it is ahead by $19,455 out of about $1.7 million earned on each side. Extend the comparison to forty years and the degree ends $557,749 ahead. Shorten it and the trade wins comfortably.
What is the head start worth?
In the example, $225,933 by the time the degree finishes. The trade path has been earning a wage for three years while the other path paid $80,000 of tuition and earned $6,000 a year around it. That is not a bonus — it is money already banked, and the degree has to out-earn the trade for two decades simply to get back to level. The head start is the whole financial case for a shorter programme, and it is why the comparison starts on the first day of either programme rather than on each graduation day.
Why does year 1 of the degree path show a negative number?
Because in that year the degree costs more than it earns. The example shows −$14,000 in year 1: $6,000 of work income less $20,000 of tuition. The running total stays negative for the first few years and the table shows it honestly rather than starting the count at graduation. The trade path shows $10,000 in the same year — $22,000 of apprenticeship income less the $12,000 programme cost.
Does starting work earlier help my retirement savings?
Yes, though less than people expect, and it eventually reverses. Putting 6% of pay into retirement at a 6% return, the example's trade path reaches $205,043 after twenty-five years against $194,139 on the degree path — an edge of $10,904, because the contributions start years earlier and compound for years longer. Run it over forty years, though, and the degree's larger later contributions win: $665,369 against $644,291, an edge of $21,078 the other way.
Are the wages on this page real figures?
No. Every wage and salary here is a field you fill in, and the defaults are illustrative only. Neither path has a single wage: pay in the skilled trades varies by trade, by region and by whether the work is unionised, and pay by degree varies enormously by field of study. The gap between two degrees is often wider than the gap between a degree and a trade. Look both up before trusting any result.
What does this comparison leave out?
A great deal that matters. It compares money only. It says nothing about physical wear and how long a body lasts in a given trade, job security, whether either field is hiring where you live, licensing and continuing-education costs, or how easily one route leads to another later. It also assumes both programmes are completed and both jobs are found. Those belong in the decision, and none of them can be calculated here.
