Loading Degree Payback Period…
Only what studying adds. Rent and food you would have paid anyway are not a cost of the degree.
After tax and any loan deducted from pay. Your own figure — the rates differ everywhere.
Zero holds the difference flat, which is the cautious reading.
13.6 years
$114,000 of cost against $8,400 kept in the first year.
Of the $114,000 total, $66,000 was never paid to anyone — it is the salary you did not earn while studying. It is invisible on a bank statement and it is usually the larger half of the bill, which is why a course that looks cheap in fees can still take years to recover.
A payback period is not a verdict on a degree. This page knows two numbers: a salary difference you supplied and a cost you supplied. It does not know whether the degree caused that difference — graduates differ from non-graduates in ways that were there before anyone enrolled, and part of any gap belongs to those differences rather than to the course. It does not know the risk that you never reach the salary you typed, which is a real chance and not a small one. It cannot see what the qualification opens up later, and it has no way at all to value the part of an education that is not money.
Money in ten years is worth less than money today, and nothing here discounts it — a payback period counts dollars as equal whenever they arrive, so treat it as a rough rank against another option rather than as a precise date. It also assumes you finish, which not everyone does, and holds the gap steady unless you enter a growth rate. Interest on borrowing is not modelled: if the cost was borrowed, add the interest from a repayment schedule to the cost above.
A payback period answers one narrow question: how long the extra money a qualification brings in takes to cover what getting it cost. It is the same calculation a business runs on a machine — outlay first, a stream of returns afterwards, and a date where the two meet. Applied to a degree it is useful precisely because it is crude. It gives you a single number to compare one course against another, or against not going at all.
Tuition is the visible cost and it is often the smaller one. The larger cost is the salary you did not earn while you were studying, and because it never appeared in a bank account it rarely appears in anyone’s reckoning either.
Three years of a course at $12,000 in fees and $4,000 of additional living cost comes to $48,000. Three years away from a job paying $28,000, with $6,000 a year earned alongside the course, gives up another $66,000. The total is $114,000, and more than half of it is money nobody ever invoiced you for. This is also why a part-time route can be far cheaper in real terms while looking identical on a fees page.
Say the degree lifts pay from $28,000 to $40,000, a gap of $12,000 a year. Tax and any loan deducted at source mean you keep some fraction of that; at 70% you are $8,400 better off each year. Against $114,000 of cost, the break-even arrives after about 13.6 years, and by year twenty you are roughly $54,000 ahead.
Now let the gap grow 2% a year, as it might if the qualification also raises the rate at which you are promoted. Break-even moves to about 12.1 years. Change the assumed salary instead and the answer swings much harder: a $16,000 gap pays back in about ten years, an $8,000 gap in over twenty. The result is far more sensitive to the salary you assume than to anything else you enter, which is the strongest reason to run it several times rather than once.
This tool knows a salary difference and a cost. That is the whole of its knowledge, and four things follow from it.
It cannot tell whether the degree caused the difference. Graduates differ from non-graduates in ways that existed before anyone applied, and some of any observed gap belongs to those differences rather than to the teaching. It has no concept of risk: the salary you type is a hope, and the chance of not reaching it is real and unevenly distributed across subjects. It ignores everything that is not money — the work you would rather be doing, the people you meet, the doors that open a decade later. And it treats a dollar in year fifteen as equal to a dollar today, which no financial analysis would accept.
Use it to rank options that are otherwise similar. Do not use it to decide whether an education was worth having.
Because giving up income is as real as writing a cheque, and leaving it out makes every full-time course look artificially cheap. Any comparison against staying in work has to account for the salary that staying in work would have paid you.
Work it out from your own payslip rather than guessing. Take the extra gross pay, subtract the additional tax and any deductions collected on that extra, and use the fraction that survives. It is very often between two thirds and three quarters, but the rates that produce it differ by country and by income.
Yes, if you borrowed. The cost field here is a total, so add the interest that a repayment schedule says you will pay on top of the fees themselves. Ignoring it can understate a long payback by several years.
Only between options you would otherwise be indifferent about. A course paying back in eight years with a narrow, fragile job market may be a worse bet than one paying back in fifteen with broad demand, and neither number captures that. Treat it as one input among several.
