What does the degree actually cost, and when does it pay you back?
Tuition is the number everyone argues about, and it is usually the smaller half of the bill. The larger half is the salary you did not earn while you were studying — nobody sends you an invoice for it, so almost nobody counts it. This tool runs both paths month by month: the degree, with its tuition and its loan, against starting work now and investing the difference. It tells you the year the degree pays for itself, or tells you plainly that it never does inside your horizon.
The free version answers the question over 20 years and says so plainly when it has clamped. Pro extends it to 50, compares three scenarios side by side, unlocks the sensitivity grid — the break-even year across a range of graduate-salary assumptions, which is the honest form of this answer — and adds image and CSV export.
The shareable link is free, for everyone, always. Pro is a separate one-time purchase — if you already subscribe to DCA Simulator Pro, this is not included in it. Worth knowing before you click, rather than at the checkout.
Educational content only — not financial advice. This compares two financial paths and nothing else. It does not price the work itself, a licence you cannot practise without, what you learn, who you meet, or the life you would rather be living. A degree that never breaks even on this chart can still be the right decision, and this tool takes no view on that. Grants, scholarships you have not been awarded, income-contingent repayment, forgiveness schemes and tax relief are not modelled. Every figure rests on assumptions you can see and change, and none of them is a forecast.
Tuition is the small half of what a degree costs.
Almost every college ROI calculator compares what you pay to what a graduate earns. That comparison omits the single largest line in the decision, and it is not a small omission — on the defaults below it is roughly two and a half times the tuition.
$64,652
Four years of tuition and fees, opening at $15,000 and rising 5% a year. This is the number on the brochure, the number in the loan paperwork, and the only number most calculators ask you for.
$158,978
Four years of salary you did not earn, starting at $38,000 and growing 3% a year. You did not write a cheque for this, which is exactly why it disappears — but it left your life all the same.
The reasoning runs in one direction and it is worth following slowly. For a degree to pay, it has to earn back what it cost. For you to know what it cost, you have to count everything you gave up to get it. And the largest thing most people give up is not money they spent — it is four years of income they never saw, at the start of a career, when compounding has the longest possible runway.
That is the line this tool exists to put back. It is not an argument against degrees. Plenty of degrees clear this bar comfortably and the tool will tell you so. It is an argument against deciding on the brochure number.
Nothing here is hidden. Check every line.
These are the tool’s opening defaults, run out by hand so you can audit the method before you trust the output. Replace all of them with your own numbers — they are placeholders, not claims about your situation.
| Year of study | Tuition and fees | Salary not earned |
|---|---|---|
| Year one | $15,000.00 | $38,000.00 |
| Year two | $15,750.00 | $39,140.00 |
| Year three | $16,537.50 | $40,314.20 |
| Year four | $17,364.38 | $41,523.63 |
| Four-year total | $64,651.88 | $158,977.83 |
The correction that changes the answer
Here is where the usual sum goes wrong, and it goes wrong the same way almost every time. The graduate starts on $60,000. The alternative was $38,000. So the degree bought a $22,000 raise, and the payback looks easy to work out.
It did not. The person who skipped the degree did not stand still for four years. At 3% a year they are on 38,000 × 1.03^4 = $42,769 by the time the graduate collects a first pay cheque. The real gap on day one is $17,231, not $22,000 — about a fifth smaller than the figure most people run the decision on.
That gap then widens, because the tool lets the two paths grow at different rates — 4% with the degree against 3% without, on the defaults. Whether the widening gap ever repays the $223,630 of tuition and foregone income, and in which year, is precisely what the calculator above is for. It will also tell you plainly when the answer is never.
What the degree ROI calculator runs, year by year.
Every assumption is a field you can see and change. Nothing is inferred about you and nothing is looked up. Your figures are sent to this site to be calculated and are never written to a database, kept after the answer comes back, or passed to anyone else.
Describe the degree
Tuition in year one, how many years, how much is borrowed and on what terms. Tuition inflation opens at 5% a year, which is deliberately higher than general inflation — it has run ahead of it for decades.
Name both salaries
What you would earn starting now, and what the degree is expected to pay on graduation. Be honest with the second one. Use the median for the actual course at the actual institution, not the figure in the prospectus.
Add what you earn while studying
This field opens at zero, which is the harshest possible reading. Part-time work during study is the cheapest single way to move the result, and the tool will show you exactly how far it moves.
Read the crossover
Both paths run to your horizon — up to twenty years free, fifty on Pro — with the surplus on each side invested. The tool reports the year the degree path overtakes, or states plainly that it does not.
The one number worth arguing about
The investment return field is where this calculation is most sensitive, so it is worth being exact about what is in it. The default is 7% real — that is, after inflation. It is rounded up from a measured 6.74%: the S&P 500 with dividends reinvested returned 10.02% a year geometric over the 98 years from 1928 to 2025 (A. Damodaran, NYU Stern), against CPI-U inflation averaging 3.07% over the same window (US Bureau of Labor Statistics). (1.1002 / 1.0307) - 1 = 6.74%.
Two honest notes about that. First, it is a rounded figure and not “the historical average” — the measured number is 6.74% and the default is 7%. Second, and more usefully, know which way it leans. For the first four years the person without the degree is the one holding surplus cash, so they are the one earning this return. A generous return therefore makes the degree look worse. If you arrived hoping to be told the degree pays, this tool is currently arguing against you — so lower the field and watch what happens rather than accepting the verdict.
One more thing to hold on to. The two salary growth rates are nominal, not real, and the form says so at the field. The inflation field at the bottom exists only to restate the final figures in today’s money. Do not deflate the growth rates yourself and set the inflation field as well, or you will subtract inflation twice and the degree will look far worse than it is.
Most complaints about this tool are correct.
A calculator that pretends to settle a question this large is lying to you. Here are the four strongest arguments against the output, including the one that is a genuine defect in the method rather than a limit on the inputs.
“You are comparing pre-tax salary to after-tax tuition.”
Correct — and it is a real flaw
This is the strongest objection and it lands. The salary you did not earn is a gross figure. The tuition you paid came out of income that had already been taxed. Setting $158,978 of foregone earnings beside $64,652 of tuition therefore overstates the foregone side, and by a wide margin at higher marginal rates.
The tool does not model your tax position and will not pretend to. Read the foregone figure as the ceiling, not the number. The direction of the argument survives — the four years still dwarf the tuition — but the multiple is smaller than 2.5x once tax is applied.
“A degree is not only a financial asset.”
Correct, and out of scope
Entirely true. Degrees buy things this tool cannot price: the licence to practise at all in medicine or law, a professional network, a visa route, four years of being a different person. None of that appears in the output and none of it should.
What the tool gives you is the size of the financial bill for those things. That is a legitimate input to a decision that is not purely financial. Plenty of people run this, see the number, and go anyway — having decided rather than assumed.
“Your defaults are made up.”
Correct — they are placeholders
They are, and the page says so rather than dressing them as research. $15,000 tuition, $38,000 alternative, $60,000 on graduation: these are plausible round numbers chosen to make the mechanism legible, not medians for any country, course or year.
The one default with a source behind it is the 7% real return, and section 03 shows the derivation and the rounding. Every other field is yours to replace. An output built on defaults you did not change is not about you.
“This assumes I finish.”
Correct, and it matters more than people expect
It does. The model runs a degree that completes on schedule, and it has no term for dropping out. That is the single worst financial outcome available here: you pay the tuition, you lose the years, and you collect the alternative wage anyway.
If you want to see it, set the graduate salary equal to the alternative salary and run it. The result is the cost of a degree that does not finish, and it is the strongest argument in favour of choosing a course you will actually complete.
Built for people who want the number before the feeling.
This is a decision tool for one specific question, run once, carefully. If the question you actually have is a different one, the honest answer is that something else will serve you better.
It fits if
- You are weighing a degree, a second degree, or a career-change qualification and want the financial half of the decision priced properly before you commit years to it.
- You are advising someone who is about to sign for a loan and you want a shared set of numbers to argue over rather than two sets of instincts.
- You suspect the brochure figure is not the whole cost and want to see how much of the bill is the four years rather than the tuition.
- You are comfortable changing assumptions and re-running, and you understand that a calculator is a way of thinking rather than an oracle.
It does not fit if
- The degree is a licence requirement. Medicine, law, accountancy, engineering in most jurisdictions — if you cannot practise without it, there is no alternative path to compare and the output is noise.
- You are already enrolled and part-way through. The tuition and the years are largely spent; the decision this tool models is behind you.
- You want a ranking of institutions or courses. This prices your two paths. It holds no data about any university and never will.
- You want the tool to tell you what to do. It reports a crossover year. Whether that year is acceptable is a judgement it cannot make for you.
The questions people ask before they trust the output.
Answered against what the tool actually does, not against what would be convenient to claim.
How do you calculate the ROI of a degree?
You run two futures side by side and find the year one overtakes the other. The degree path pays tuition, earns little or nothing during the study years, then earns the graduate salary. The alternative path starts earning immediately at a lower wage and invests the surplus. Return on a degree is the year the first path passes the second — not a percentage, and not a comparison of tuition to a starting salary.
The part that decides the answer is the part most calculations omit: the salary you did not earn while studying. On this tool’s defaults that is $158,978 against $64,652 of tuition, so the years cost roughly two and a half times what the fees do before tax is considered.
What is the opportunity cost of going to university?
It is the income you gave up, plus what that income would have compounded to had you invested it. Four years at $38,000 growing 3% a year comes to $158,978 of foregone earnings. That sum then loses its own future growth as well, which is why the cost of study years lands so much harder at 18 than at 40 — early money has the longest runway.
One honest caveat. Foregone salary is a pre-tax figure while tuition is paid from taxed income, so the two are not strictly comparable and the multiple above is a ceiling rather than a measurement.
Does the calculator include student loan interest?
Yes. You set the share of tuition that is borrowed, the interest rate and the repayment term — opening at 100% borrowed, 6%, over ten years, with the term adjustable up to thirty. The loan is drawn as tuition is actually paid rather than as a single sum on day one, so the interest the tool reports will not match a simple amortisation of the four-year total.
Set the borrowed share to zero to model paying cash, and compare the two runs. The difference between them is what the loan costs you, stated separately from what the degree costs you.
What graduate salary should I enter?
The median starting salary for the specific course at the specific institution, if it publishes one. Not the average across all graduates, which is pulled upward by a small number of very high earners, and not the figure in the prospectus, which is a marketing document.
There is a trap in the comparison worth naming. The default gap looks like $60,000 against $38,000, or $22,000. It is not: the person who started work four years ago is on 38,000 × 1.03^4 = $42,769 by graduation day, so the real gap is $17,231. Compare the graduate salary to what the alternative has grown into, never to what it was.
What if I work part-time while studying?
Enter it in the earnings-while-studying field, which opens at zero as the harshest case. This is the cheapest lever on the whole page: every dollar earned during study reduces the foregone-income side directly, and does it in the earliest years, where the compounding effect is largest.
Run it at zero, then run it again at what you would realistically earn. The distance between those two crossover years is the financial value of working through your degree, and for most inputs it is larger than people expect.
Is my data saved or sent anywhere?
No. There is no account, no email gate and no sign-up. Your figures are sent to this site to be calculated, and the answer comes straight back — no salary, tuition figure or result is written to a database, kept after the response, or passed to any third party. The only thing this page stores in your browser is whether you chose dark mode.
The shareable result link is free for everyone and always will be, and it carries only the assumptions you chose. Nothing is inferred about you and nothing is looked up.
Everything above stays free. Pro goes further.
Pro extends the horizon to fifty years, compares three scenarios side by side, unlocks the sensitivity grid — the break-even year across a range of graduate-salary assumptions, which is the honest form of this answer — and adds image and CSV export.
