Graduate school is one of the most expensive purchases you will ever make, and the sticker price is only the beginning. Tuition gets all the attention, but rent, food, health insurance, fees, textbooks and foregone salary often add up to more than the tuition itself. This graduate school cost calculator rolls every line into one number — the true total cost of your degree — and then converts the amount you borrow into a monthly payment and a lifetime repayment figure, so you can see exactly what that diploma will cost you after graduation.
Adjust the sliders and every result updates instantly. Add a scholarship, push out your repayment term, or raise your savings contribution to watch the monthly bill shrink.
How to Use
- Enter Annual Tuition — the published yearly rate for your specific program, not the university's general undergraduate figure.
- Set Annual Living Expenses using the cost of living in your school's actual city. A program in San Francisco will feel very different from one in the Midwest, even with identical tuition.
- Add Fees, Books & Supplies. Most graduate students forget health insurance, lab fees, software subscriptions and travel to conferences — budget roughly $1,500–$5,000 per year.
- Choose your Program Length. Most master's degrees run two years; engineering and business often stretch to two; PhDs typically take four to six.
- Enter Scholarships & Grants in total dollars over the whole program. This includes fellowships, teaching assistantships, research assistantships and external awards.
- Add Out-of-Pocket Savings — money you or family will contribute while you are enrolled. Every dollar here is a dollar you do not have to borrow at interest.
- Set your expected Loan Interest Rate (APR). Federal Direct Grad PLUS loans are repriced annually; if you have not locked a rate yet, plug in 6%–8% as a planning estimate.
- Choose your Repayment Term. The standard federal plan is 10 years; stretching to 20 or 25 lowers the monthly bill but roughly doubles the interest you pay.
The result card shows the total program cost, your net cost after aid, the amount you actually need to borrow, your monthly payment after graduation, the total you will repay over the term, the interest alone, and the full lifetime out-of-pocket cost (savings plus every loan payment).
The Loan Payment Formula
Your monthly student-loan payment uses the same standard amortization formula that Fannie Mae and the U.S. Department of Education rely on:
M = P × r(1 + r)ⁿ / ((1 + r)ⁿ − 1)
Where:
- M is the monthly payment.
- P is the loan principal — your net cost minus scholarships and savings.
- r is the monthly interest rate — the annual APR divided by 12.
- n is the total number of monthly payments — the repayment term in years times 12.
Worked example on a $40,000/year tuition, $25,000/year living program over two years: total cost is (40,000 + 25,000) × 2 = $130,000. Subtract a $20,000 scholarship and you borrow $110,000. At a 6.0% APR repaid over 10 years, the monthly rate is 0.005 and n = 120. The monthly payment works out to $1,221.23, and over 120 months you repay a total of about $146,547 — meaning $36,547 of interest on top of the original $110,000.
If the interest rate is 0%, the formula divides by zero, so the engine simply splits the principal evenly across the number of months. On a $40,000 interest-free loan over 10 years, that is $333.33 per month and $0 of interest.
What Goes Into the True Cost of Grad School
Prospective students routinely under-budget by 30–50% because they only look at tuition. A realistic budget stacks five layers:
- Tuition — the per-credit or per-year rate published by the program.
- Fees — student activity fees, health insurance, technology fees, lab fees and graduation fees; often $1,000–$5,000 per year.
- Books and supplies — textbooks, software (many graduate programs require expensive statistical or engineering suites), a laptop, and conference travel.
- Living expenses — rent, food, utilities, transport and personal spending. In an expensive city this alone can exceed tuition.
- Foregone salary — the wages you give up while studying full-time. This is not a cash outlay, but it is a real economic cost that any serious ROI comparison must include.
A $50,000/year tuition with a $30,000/year living cost is $80,000 per year — and over a two-year master's that is $160,000 before interest. Add foregone salary and the true bill can approach a quarter of a million dollars.
10-Year vs 20-Year Repayment
Stretching your loan term is the single biggest lever on the monthly bill, but it comes at a price. Compare the same $110,000 loan at 6%:
- 10-year term: about $1,221/month, total interest around $36,500.
- 20-year term: about $787/month, but total interest balloons to roughly $78,000.
The 20-year plan lowers the monthly burden by nearly $430, which can be the difference between affording rent and not, but it costs you over $40,000 in extra interest. Choose the longer term if you need the cash flow in your early career (especially if you plan to pursue Public Service Loan Forgiveness), but pay extra toward principal whenever you can to claw back the interest.
Examples
Example 1 — A full-time MBA with partial scholarship. A student pays $40,000/year tuition, budgets $25,000/year for rent and food, adds $2,000/year in fees and books, and attends a 2-year program. Total cost is $134,000. A $20,000 fellowship and $0 savings leaves a $114,000 loan. At 6% over 10 years, the monthly payment is about $1,267 and total repayment is roughly $152,000.
Example 2 — A PhD with a full stipend. A doctoral candidate receives tuition remission plus a $30,000/year living stipend, so tuition and living both net to $0 out of pocket. They borrow $5,000 for fees and moving costs over five years. At 5% over 10 years, the monthly payment is under $53 — a tiny burden relative to the lifetime earnings premium a PhD confers.
Example 3 — A high-cost private master's. Tuition is $60,000/year, living $30,000/year, fees $5,000/year, over two years, with only a $10,000 scholarship. Total cost is $190,000; the loan is $180,000. At 7% over 10 years the monthly payment is about $2,087 and total repayment hits $250,000. Running this number before applying is the best way to avoid signing up for a payment you cannot service.
Example 4 — The savings effect. On the same $110,000 loan, putting $25,000 of savings toward the balance at graduation drops principal to $85,000. The 10-year monthly payment falls from $1,221 to about $942, and total interest shrinks from $36,500 to roughly $28,300 — an immediate $8,000+ saving.
FAQ
How much does graduate school actually cost?
The average U.S. master's degree costs between $30,000 and $120,000 total, depending on the field and school. Tuition alone ranges from $15,000 to $60,000 per year, but once you add rent, food, fees and books, the true annual outlay is usually 50–100% higher than the tuition line. This calculator lets you stack all of those lines and see the full number.
Should I take out loans for grad school?
It depends on the expected earnings premium. A professional degree with a clear salary payoff (law, medicine, engineering, MBA at a top program) often justifies borrowing, especially if you target Public Service Loan Forgiveness. A low-paying master's with no clear career boost can leave you servicing $1,000+ monthly payments for a decade. Use this calculator next to a starting-salary estimate to judge whether the payment is below 8–10% of your gross monthly income.
What is the average grad school loan payment?
Borrowers who finish a master's typically owe $30,000–$70,000 and pay $350–$800 per month on a standard 10-year plan. PhD recipients with tuition remission often owe far less, while professional-degree recipients (law, medicine, dental) can owe six figures and face payments of $1,500–$3,000 per month.
How does grad PLUS interest work?
Federal Direct Grad PLUS loans disbursed after July 1 carry a fixed interest rate set annually by Congress, plus a 4.05% origination fee taken out of each disbursement. Interest starts accruing immediately while you are in school; you can let it capitalize (roll into principal at graduation) or make small interest payments to keep the loan balance from ballooning. Private loans usually have variable rates that can be cheaper initially but rise over time.
Is a 10-year or 20-year repayment plan better?
A 10-year plan costs much less in total interest but requires a higher monthly payment. A 20-year plan eases cash flow in your first working years but can double your interest bill. If you work for a government or nonprofit employer, the 10-year plan plus Public Service Loan Forgiveness after 120 qualifying payments may be the optimal path. Use the Repayment Term selector on this page to compare the two side by side.
Do scholarships and grants reduce what I borrow?
Yes — every dollar of scholarship, fellowship, grant or assistantship is a dollar that does not need to be financed. In this calculator, enter your total aid in the Scholarships & Grants field; it is subtracted directly from total program cost before the loan amount is computed. Teaching and research assistantships that cover tuition should be entered as the full tuition-equivalent value.
Does the calculator include undergrad loans I already have?
No. This tool models only the cost of the graduate program itself. To see your true post-graduation monthly burden, add your existing undergraduate loan payment to the monthly result, or run the calculation again by adding your outstanding undergrad balance to the loan principal.
