How to use
- 01
Enter the dorm cost a term, the number of terms in your academic year, and the meal plan cost a term. Together these are what the institution would charge you.
- 02
Enter the apartment's rent a month for the whole unit before splitting, the months on the lease, and the months your academic year actually covers. The gap between the last two is where most of the surprise lives.
- 03
Enter the running costs: utilities and internet for the whole unit, then your own renters insurance, groceries and getting to campus. The first two are split with roommates; the last three are yours alone.
- 04
Enter furniture and deposits as a one-off for the whole unit, and the number of roommates you would split the rent, utilities, internet and furniture with.
- 05
Read the cost a year each way, the monthly difference, the summer months a twelve-month lease adds, and the rent at which the two tie. The line-by-line table shows where each dollar goes.
Formula
Dorm side = (the dorm cost a term + the meal plan cost a term) × the terms in the academic year. Apartment side: rent, utilities, internet and the one-off furniture and deposit are entered for the whole unit and divided by the number of people, which is your roommates plus you. Renters insurance, groceries and getting to campus are yours alone and are not divided. Apartment a year = (your share of rent + your share of utilities and internet + your own monthly costs) × the months on the lease + your share of the one-off costs. Monthly difference = the apartment's monthly total − the dorm's cost spread across the months the dorm actually covers. A negative figure means the apartment is cheaper per month, which a twelve-month lease can still reverse over a year. Summer months = the lease months − the academic months, never below zero, and their cost is the apartment's monthly total times those months. Rent at which the two tie = ((the dorm's yearly cost − your share of the one-off costs) ÷ the lease months − your own monthly costs) × the number of people, less utilities and internet for the whole unit. Reported only where it comes out above zero.
Example
A dorm costs $4,800 a term with a $2,600 meal plan, over two terms: $14,800 for the academic year, which runs nine months. The alternative is an apartment at $1,400 a month on a twelve-month lease, shared with one roommate, with $120 of utilities and $60 of internet for the unit, $15 of renters insurance, $350 of groceries and $80 of getting to campus for the student alone, and $2,000 of furniture and deposits for the unit. Your share of the rent is $700 and the apartment runs $1,235 a month all in, plus $1,000 as your half of the furniture and deposit: $15,820 for the year. That is $1,020 more than the dorm, even though $1,235 a month is $409 less than the $1,644 the dorm works out at across the nine months it covers. The three summer months are the difference — they add $3,705. The line-by-line table makes the swap visible: housing costs $9,600 in the dorm against $8,400 in the apartment, but the apartment then adds utilities, internet, insurance, transport and furniture that the dorm charge already included. The two tie at a whole-unit rent of about $1,230 a month. Two variations, both run. A nine-month lease on the same apartment costs $12,115 and saves $2,685 against the dorm, with no summer months and a tie rent of $1,997. Living alone in the same apartment costs $26,300 — $11,500 more than the dorm — and the tie rent falls to $442.
Definitions
- Academic year
- The months an institution's housing contract actually covers, usually about nine. The gap between it and a twelve-month lease is what turns a cheaper monthly rent into a dearer year.
- Summer months
- The lease months falling outside the academic year. They cost full rent whether or not you are in town, and subletting them is the usual remedy — where the lease permits it.
- Shared costs
- Rent, utilities, internet and furniture, entered for the whole unit and divided between everyone living there. The lever that most changes the comparison.
- Personal costs
- Renters insurance, groceries and getting to campus. They do not fall when a roommate joins, which is why each extra person saves less than the rent split alone suggests.
- Tie rent
- The whole-unit rent at which the apartment and the dorm cost the same over a year, on everything else as entered. Below it the apartment wins; above it the dorm does.
Good to know
The twelve-month lease against the nine-month year
This is the trap the page exists to show, and it catches people because the monthly arithmetic genuinely favours the apartment. In the worked example the apartment costs $1,235 a month all in, against the $1,644 a month the dorm and meal plan work out at across the nine months they cover. On a monthly basis the apartment is $409 cheaper, which is the comparison most students make and the one that gets repeated. Yet over a year the apartment costs $15,820 against $14,800, so the dorm is $1,020 cheaper. Both statements are true at once, and the reconciliation is the lease. A dorm contract ends when the academic year does. A twelve-month lease does not. Three months therefore fall outside the academic year, and they cost $3,705 whether or not you are in town — more than enough to reverse a $409 monthly advantage. The page counts those months explicitly and names them in the monthly comparison, precisely so the two figures cannot be read as contradicting each other. Change only the lease length and the whole answer changes. A nine-month lease on the same apartment costs $12,115 and saves $2,685 against the dorm rather than costing $1,020 more, and the rent at which the two tie rises from $1,230 a month to $1,997. That is an enormous swing produced by a single term of the contract, and it is why lease length deserves as much negotiating attention as rent. There are only three real answers to the summer months. Sublet them, which requires that the lease permit subletting — many forbid it outright, and this is worth confirming in writing before signing rather than discovering in April. Find a nine- or ten-month lease, which some markets near campuses offer and most do not. Or plan to stay and work through the summer, so the months earn their keep rather than merely costing rent. If none of the three applies to your situation, the summer months are a real cost and belong in the comparison at full price.
What a dorm charge already includes
Comparing a rent figure with a dorm charge is not comparing like with like, and the error runs consistently in one direction. A dorm charge typically bundles utilities, internet, insurance, furniture and maintenance, and places you within walking distance of campus. Rent buys you the room and nothing else. Every one of those bundled items reappears as a separate line once you move out, and the page adds them back so the two sides are genuinely comparable. The line-by-line table in the worked example makes the swap visible. On housing alone the dorm costs $9,600 against the apartment's $8,400 — the apartment is genuinely cheaper for shelter. But the apartment then adds $1,080 a year of utilities and internet as your share, $180 of renters insurance, $960 of getting to campus and $1,000 as your half of the furniture and deposits. Those four lines come to $3,220, and they are the difference between an apartment that looks cheaper and one that is not. A student who compares $8,400 of rent against $9,600 of dorm housing and concludes the apartment saves $1,200 has made a $3,220 error, and it is the commonest error in this decision. Two of those lines deserve particular care because they are easy to underestimate. Utilities vary seasonally and by the age and insulation of the building, so a figure quoted by a departing tenant in October may bear little relation to a January bill; ask for a twelve-month average rather than a recent one. Furniture and deposits are a genuine one-off rather than an annual cost, which is why the page treats them separately and splits them — but the deposit portion is only partly a cost, since a returnable deposit comes back if the property is left in good order, while furniture does not. Someone staying for several years spreads those one-offs across all of them, which improves the apartment's case considerably in years two and three. The page prices a single year, so read the one-off line with your own intended tenure in mind.
Roommates split some costs and not others
The number of people sharing is usually the single largest lever in this comparison, and it is more powerful than rent itself. In the worked example, splitting a $1,400 apartment with one roommate takes your share of the rent to $700 a month and produces an annual cost of $15,820, which is within about $1,000 of the dorm. Live in the same apartment alone and it costs $26,300 — $11,500 more than the dorm, and no longer a close decision at all. The rent at which the two options tie tells the same story from another angle: it is $1,230 a month for the whole unit when shared with one person, and only $442 when living alone, which is below any realistic rent. Living alone near a campus is very rarely cheaper than a dorm, and the page makes that unambiguous. But the saving from each additional roommate is smaller than people expect, and the reason is worth understanding. Only some costs divide. Rent, utilities, internet and the one-off furniture and deposits are entered for the whole unit and split between everyone living there. Renters insurance, groceries and getting to campus do not divide at all — they are yours whether you live with three people or none. In the example those personal costs come to $445 a month, and they are unaffected by the number of roommates. So the first roommate halves the largest block of costs and transforms the comparison; the third and fourth make progressively less difference, because an increasing share of what remains is personal. There is a practical warning attached. These savings assume every roommate pays their share on time for the full term of the lease, which is an assumption about other people rather than about money. Where a lease is joint and several — as most are — each tenant is legally liable for the entire rent, not merely their share, so one roommate leaving or defaulting does not reduce your obligation to the landlord. The arithmetic on this page describes the intended arrangement; the lease describes what happens when the arrangement fails.
The meal plan swap, and where to check these numbers properly
Replacing a meal plan with your own cooking is the largest single swing in this comparison, and it is the number students most often get wrong. In the worked example the meal plan costs $2,600 a term, $5,200 a year, against $350 a month of groceries, $4,200 a year — a saving of $1,000. That saving is real but modest, and it rests entirely on a grocery figure that is easy to set optimistically. Someone who cooks less than they intended, orders in during exam periods, or shops without a list can spend well above $350 a month, and at around $433 a month the saving disappears entirely. Because the whole comparison in this example turns on about $1,000 a year, the grocery field alone can flip the answer. It deserves a proper estimate rather than a hopeful one, ideally from a few months of your own actual spending rather than from what a budget suggests food ought to cost. Three of this page's fields are deliberately single figures standing in for whole calculations, and each has a page of its own where the real work belongs. Groceries are one: what food at home genuinely costs for a household is a question with its own calculator, and it is worth answering there and bringing the result back. The cash a lease demands before you get the keys is another — the deposit, first month, application and administrative fees are itemised properly elsewhere, and the one-off field here is a summary of them rather than a substitute. Getting to campus is the third: a single monthly figure hides fuel, parking, insurance and the hours the journey takes, which a commute calculation sets out in full. There is also a prior question this page does not ask. It compares two housing options on cost alone and takes no view on whether either is affordable. Before signing a lease, check what rent your income actually supports, because an apartment that beats a dorm on this page can still be more than your budget can carry.
Frequently asked questions
Is living off campus cheaper than a dorm?
Often less than it looks. In this page's example the apartment costs $15,820 a year against $14,800 for the dorm and meal plan — so the dorm is $1,020 cheaper, despite the apartment costing less every month. The reason is the lease: the apartment is $1,235 a month against $1,644 for each of the nine months the dorm covers, but the three summer months outside the academic year add $3,705 and reverse the result.
What is the twelve-month lease trap?
A dorm contract ends when the academic year does; a twelve-month lease does not. In the example that means three months of rent falling in a summer when the dorm would have cost nothing — $3,705. Take a nine-month lease instead and the same apartment costs $12,115, saving $2,685 against the dorm rather than costing $1,020 more. There are only three answers to it: sublet the summer, find a nine- or ten-month lease, or plan to stay and work so the months earn their keep. Ask before signing whether subletting is permitted, because many leases forbid it.
How much difference do roommates make?
They usually decide the answer. In the example, splitting with one roommate takes your share of the rent to $700 a month out of $1,400, and the apartment costs $15,820 a year. The same apartment alone costs $26,300 — $11,500 more than the dorm. But the saving from each extra person is smaller than people expect, because groceries, renters insurance and getting to campus stay yours alone and do not fall when a roommate joins.
At what rent do the two break even?
In the example, about $1,230 a month for the whole unit — below that the apartment wins, above it the dorm does. That figure moves sharply with everything else: on a nine-month lease it rises to $1,997, because the summer months no longer count against the apartment, and living alone it falls to $442, which is below any realistic rent. Where it comes out negative, the page says plainly that no rent ties the two, because even a rent-free apartment would cost more once the other lines are counted.
What does a dorm price include that rent does not?
Usually utilities, internet, insurance, furniture and maintenance, and it sits within walking distance of campus. The example apartment adds all of those back: $1,080 a year of utilities and internet as your share, $180 of renters insurance, $960 of getting to campus and $1,000 of furniture and deposit. Comparing a rent figure with a dorm charge without adding those back will always flatter the apartment.
Does replacing the meal plan with groceries save money?
It is the largest single swing in the comparison, and this page takes your own figure for it rather than asserting one. The example uses $350 a month of groceries — $4,200 a year — against a meal plan of $2,600 a term, $5,200 a year. Whether your own cooking really costs that is worth checking properly rather than guessing, because it is easy to underestimate and it moves the result more than rent does at the margin.
