How to use
- 01
Enter the total cost of the degree net of grants and scholarships, adding every year together, and the number of years in school. If you only have a sticker price and an aid offer, work the net price out first and bring the result here.
- 02
Enter the two starting salaries: what you would earn with the degree in your field, and what you would earn without it on the work you would do instead. The gap between them drives the whole answer, so use real figures for your field and region rather than national averages.
- 03
Enter the earnings you give up each year while studying. Enter the full amount you would have earned to model leaving work entirely, or a smaller figure if you would keep working part-time.
- 04
Set the growth rate on each path, the years to compare, the share of the cost you borrow and your marginal tax rate. The loan rate and the two NCES medians keep their sourced defaults unless you change them.
- 05
Read the break-even year, then the year-by-year table of both paths and the chart of the two running totals. Check the premium after tax and after loan payments, which is the figure that actually reaches your bank account.
Formula
Two paths run side by side from year 1, the first year of school. No-degree path each year = the starting salary without the degree, grown at its own rate, times (1 − your marginal tax rate). Degree path each year, while in school = (the no-degree salary that year − the earnings you give up), never below zero, times (1 − tax rate), less the share of the year's tuition you pay in cash rather than borrow. The opportunity cost enters here, by subtraction, and is never added again as a separate charge. Degree path each year, after school = the starting salary with the degree, grown at its own rate, times (1 − tax rate), less the annual loan payment for as long as the loan runs. The loan = the borrowed share drawn evenly across the years in school, each drawing accruing interest to graduation. The standard plan's term follows from that balance under the 2026 tiers (under $25,000 → 10 years; $25,000 to under $50,000 → 15; $50,000 to under $100,000 → 20; $100,000 or more → 25), and the payment is the ordinary amortizing-payment formula. Break-even = the first year after school in which the degree path's running total reaches the no-degree path's. The lifetime gap is the difference between the two running totals at the last year compared.
Example
A degree costs $80,000 net of grants and scholarships over four years. The student gives up $25,000 of earnings each year while studying, expects $60,000 on graduating against $40,000 without the degree, and assumes 3% growth with it and 2% without, over twenty years, at a 25% marginal rate, borrowing half the cost at the 6.52% undergraduate rate. Year 1 the degree path clears $1,250 — $15,000 of reduced earnings after tax, less $10,000 of tuition paid in cash — against $30,000 on the no-degree path, a gap of $28,750 against it. The $40,000 borrowed reaches $46,959 by graduation, repaying over fifteen years at $410 a month, and interest adds $33,725, so the degree costs $113,725 all in. In the first year out, the degree earns $60,000 against $43,297, a premium of $16,703 before tax, $12,527 after tax and $7,612 after loan payments. The two paths cross in year 15. By year 20 the degree path has cleared $841,983 after tax against $728,921, a difference of $113,062. Change one thing at a time and the answer moves: paying cash rather than borrowing half brings the crossing to year 14 and widens the gap to $146,787; keeping your job through school so nothing is given up brings it to year 9 and $188,062; and comparing thirty years instead of twenty leaves the crossing at year 15 but widens the gap to $452,768.
Definitions
- Net price
- The cost of a degree after grants and scholarships that never have to be repaid, but before loans. Loans are not aid in this sense: they are the cost, deferred and with interest added.
- Opportunity cost
- The earnings given up by studying rather than working. Usually the largest single cost of a degree, and the one most often left out of informal comparisons. Here it is 56% of the total cost in the worked example.
- Break-even year
- The first year in which the degree path's cumulative after-tax earnings, net of tuition and loan payments, reach the no-degree path's. Counted from the first year of school so the years out of work are included.
- Earnings premium
- The gap between what the two paths earn in a given year. Worth reading three ways: before tax, after tax, and after loan payments, because only the last is money you can spend.
- Standard plan tiers
- For loans made on or after 2026-07-01, P.L. 119-21 sets the standard repayment term from the balance when repayment starts: 10 years under $25,000, 15 to under $50,000, 20 to under $100,000, and 25 above that.
Good to know
Why the clock starts on the first day of school
Most informal comparisons of a degree against no degree begin counting on graduation day. That single choice quietly makes the years in school free, and it flatters every degree ever considered. This page starts the clock on the first day of school instead, and the difference is large. In the worked example a student pays $80,000 net of grants and scholarships across four years and gives up $25,000 of earnings in each of those years. The earnings given up come to $100,000, against $80,000 of tuition — so the opportunity cost is 56% of what the degree really costs, and it is the part nobody puts on a spreadsheet. Year 1 of the table shows what this looks like in practice: the degree path clears $1,250, being $15,000 of reduced earnings after tax less $10,000 of tuition paid in cash, while the path without the degree clears $30,000. The degree starts the race $28,750 behind and keeps falling further behind until it graduates. The way the page handles opportunity cost is worth understanding, because it is easy to double-count. During the school years the degree path earns whatever the no-degree path earns, less the earnings you say you are giving up. That subtraction is the entire mechanism. The cost of the years out of work is never added again as a separate charge at the end, which is the commonest error in homemade versions of this calculation. It also means the field is a dial rather than a switch: enter the full salary to model leaving work completely, or a smaller figure to model keeping a part-time job through school. The effect on the answer is substantial. With $25,000 a year given up, the example's two paths cross in year 15. Set that field to zero, modelling a student who keeps working throughout, and they cross in year 9 — six years earlier, with the twenty-year gap widening from $113,062 to $188,062. Before reading anything into a break-even year, check that this field reflects what you would actually do.
What borrowing adds, and how the 2026 standard plan sets the term
Tuition is not the price of a borrowed degree; tuition plus interest is. The page models borrowing the way it actually happens rather than as a single lump at the end. The share of the cost you borrow is drawn evenly across the years in school, and each drawing accrues interest from the moment it is made until graduation. In the example, borrowing half of an $80,000 degree means $40,000 drawn across four years at the 6.52% undergraduate rate set for loans first disbursed between 2026-07-01 and 2027-06-30 by Federal Register 2026-18493. By graduation that $40,000 has become $46,959 — nearly $7,000 of interest accrued before a single payment falls due, which is the part of unsubsidized borrowing that surprises people most. What happens next is governed by a rule that changed in 2026. For loans made on or after 2026-07-01, Public Law 119-21 sets the standard repayment term from the total outstanding principal when repayment starts, in four tiers: under $25,000 repays over ten years, $25,000 to under $50,000 over fifteen, $50,000 to under $100,000 over twenty, and $100,000 or more over twenty-five. The example's $46,959 balance falls in the second tier, so it repays over fifteen years at $410 a month. Interest across the life of the loan adds $33,725, so the degree that cost $80,000 net of aid actually costs $113,725. That interest does not merely make the degree dearer; it delays the point at which it pays for itself, because the payment is subtracted from the degree path every year it runs. Paying cash rather than borrowing half brings the crossing forward from year 15 to year 14 and widens the twenty-year gap from $113,062 to $146,787. The tiers also produce a result worth noticing: because the term is set by the balance, borrowing a little more can push you into a longer tier and a smaller monthly payment that runs for five more years. A lower payment is not automatically a cheaper loan.
Three premiums, and only one of them reaches your bank account
The earnings premium is the number the whole decision rests on, and it is quoted in at least three different ways that differ by thousands of dollars a year. This page prints all three deliberately, because the gap between them is where optimism hides. Take the first year out of school in the worked example. The degree earns $60,000. The path without the degree, having grown at 2% a year for four years, now earns $43,297 rather than the $40,000 it started at — a detail that matters, because comparing a graduate salary against the alternative's starting salary overstates the premium permanently. The gross premium is therefore $16,703. Tax at a 25% marginal rate takes it to $12,527. The loan payment of $4,915 a year takes it to $7,612. That last figure is the one that reaches your bank account, and it is 46% of the number a prospectus would print. The three are worth carrying around separately. The gross premium is what job postings and salary surveys describe. The after-tax premium is what your household budget sees. The premium after loan payments is what you can actually spend, and on some perfectly ordinary inputs it is negative in the early years — a graduate who earns meaningfully more than the alternative but takes home less each month because the repayments swallow the difference. The page flags that case explicitly rather than burying it, because it is a real and disorienting experience for new graduates and it does not mean the degree was a mistake. It resolves as the loan ends or the salary gap widens. Which of those happens first depends on the two growth rates, and that is why the year-by-year table matters more than any single year's premium. A degree whose salary grows faster pulls away from the alternative and compounds; one whose growth merely matches never closes the gap the early years opened, no matter how large the first-year premium looked.
What a national median can and cannot tell you
The page prints two national figures for reference and refuses to build anything on them. The National Center for Education Statistics, in the Condition of Education indicator on annual earnings by educational attainment, puts median earnings for 25- to 34-year-olds working full time, year round, at $66,600 for those whose highest attainment is a bachelor's degree and $41,800 for those who completed high school, both for 2022. The gap is $24,800. The same body of data puts an associate's degree at $49,470 and some college with no degree at $45,230, and those two figures deserve as much attention as the headline pair, because they describe the outcomes of people who started a degree and did not finish it. Three cautions apply before anyone treats $24,800 as a personal forecast. First, a median is the middle of a distribution, so half of all bachelor's graduates earn less than $66,600, and the spread around it is enormous. Published median earnings by field of study vary so widely that the gap between two degrees is routinely larger than the gap between having a degree and not having one. Engineering, nursing, teaching and fine arts do not share an outcome, and no national average describes any of them. Second, these are earnings of people who already completed the qualification. They say nothing about the risk of not finishing, which is a real cost borne by anyone who pays tuition and leaves without the credential. Third, the figures describe 2022 and are not a projection. The remedy is to replace them with something specific to you. College Scorecard, at collegescorecard.ed.gov, publishes median earnings by field of study and by institution, which is the right granularity for this decision: not what graduates earn, but what graduates of your programme at your institution earn. Look that up, use it in the salary fields, and treat the result as arithmetic on your own assumptions rather than as a forecast about your life.
Frequently asked questions
How long does a college degree take to pay for itself?
On this page's example it takes until year 15, counting from the first year of school — eleven years after graduating. That example is an $80,000 degree net of aid, four years in school, $25,000 of earnings given up each year, and a starting salary of $60,000 against $40,000 without the degree. Over twenty years the degree path clears $841,983 after tax and the no-degree path $728,921, a difference of $113,062. The break-even moves a great deal with the inputs: paying cash instead of borrowing half brings it forward to year 14, and keeping your job through school instead of giving up $25,000 a year brings it forward to year 9.
Why does the break-even count the years I am in school?
Because those years are the largest part of the cost. In the example, four years of school give up $100,000 of earnings against $80,000 of tuition net of aid, so the earnings forgone are 56% of the total. A comparison that starts counting on graduation day has quietly made the years in school free, which flatters every degree. Starting the clock on the first day of school is the honest way to do it, and it is why year 1 of the table shows the degree path earning $1,250 against $30,000 on the other path.
Does this page tell me what my degree will pay?
No, and it deliberately does not try. Every salary on the page is a field you fill in. Published median earnings vary enormously by field of study and by institution — engineering, nursing, teaching and fine arts do not share an outcome, and the spread between two degrees is often wider than the gap between a degree and no degree. Look your own programme up on College Scorecard at collegescorecard.ed.gov, which reports median earnings by field of study and institution, and use that figure here.
What are the NCES figures on the page for?
For scale, not for prediction. NCES put median earnings for 25- to 34-year-olds working full time, year round, at $66,600 for a bachelor's degree and $41,800 for high school completion in 2022, a gap of $24,800. The same source puts an associate's degree at $49,470 and some college with no degree at $45,230. They are medians across every field, so half of all graduates earn less. They are useful for checking whether the salary you typed is plausible, and useless as a forecast for one person.
How does borrowing change the answer?
It adds interest and it delays the payoff. In the example, borrowing half of an $80,000 degree means $40,000 drawn across four years, which reaches $46,959 by graduation because interest accrues from each drawing. Under the tiers P.L. 119-21 set for loans made on or after 2026-07-01, that balance repays over fifteen years at $410 a month. Interest adds $33,725, so the degree costs $113,725 all in rather than $80,000, and the break-even slips from year 14 to year 15.
Why is the premium after loan payments so much smaller than the raw premium?
Because tax and repayments both come out of it. In the first year out of school the example degree earns $60,000 against $43,297 on the other path, a premium of $16,703 before tax. Tax at 25% takes it to $12,527, and the $4,915 a year of loan payments takes it to $7,612. The gross premium is the number people quote; the last one is the number they live on. It is worth checking whether the figure is still positive in the early years, because on some inputs it is not.
Should I use this page to decide whether to go to college?
Use it as one input. It is arithmetic on assumptions you supply, and it compares money only. It says nothing about what the work is like, whether the field is hiring where you live, the risk of not finishing, or what a degree opens up later that no salary projection captures. It also assumes you complete the degree, which not everyone does. Treat the break-even year as a way to test how sensitive the decision is to the salary gap, rather than as the decision itself.
